My thoughts on Slackware, life and everything

Month: February 2022 (Page 2 of 2)

LibreOffice 7.3.0 for Slackware 15.0 (and -current)

LibreOffice Community Edition 7.3.0 was released last week… on the day we were preparing the Slackware 15.0 release. You’ll forgive me that my focus was elsewhere and that it took until today to upload a new set of packages for Slackware 15.0 and -current.

The main selling point of the 7.3 release cycle is better interoperability with Microsoft’s Office file formats. Note that the Microsoft proprietary file formats are still based on a deprecated standard (since 2008 actually), whereas LibreOffice uses the ISO standard OpenDocument Format.
These improvements center on three areas (text copied partly from the release notes):

  • New ways to handle change tracking in tables and when text is moved, which have a positive impact on interoperability with Microsoft Office documents.
  • Performance improvements when opening large DOCX and XLSX/XLSM files. Improved rendering speed in general, but particularly of some complex documents.
  • Improvements to the import/export filters for the Microsoft Office document formats.

Furthermore, a lot of effort has gone into improving the first experiences of people who are migrating away from the Microsoft Office suite. The LibreOffice Help being the prime target since that is where new users look to understand the different ways of working with the LibreOffice applications.

The new libreoffice packages can be found in my repository (https://slackware.nl/people/alien/slackbuilds/libreoffice/) or any mirror if you wait a day, for instance https://slackware.uk/people/alien/slackbuilds/libreoffice/ . Rsync access is also available for these servers.


Enjoy the new release – Eric

PS:
A reminder for people running slackware-current and using my packages but not reading my blog… you slacker! I hope some else points you to this page.
Sometimes Slackware updates its boost, icu4c and poppler packages and a lot of non-Slackware packages break as a result of required shared libraries gone missing.
For that reason, my repository also contains the packages ‘boost-compat‘, icu4c-compat‘ and ‘poppler-compat‘.
Note that this ‘compat‘ has nothing to do with my multilib ‘compat32‘ packages! The three ‘compat‘ packages contain older versions of the Slackware packages in -current for compatibility with binary packages that are broken until their maintainer recompiles them.
You can install ‘boost-compat’, icu4c-compat’ and ‘poppler-compat’ alongside their brethren, they do not conflict with or replace them.

Slackware Cloud Server Series, Episode 4: Productivity Platform

Hi all!
Welcome to the fourth episode in a series of articles that I am writing about using Slackware as your private/personal ‘cloud server’.
Check out the list below which shows past, present and future episodes in the series, if the article has already been written you’ll be able to click on the subject.
The first episode also contains an introduction with some more detail about what you can expect.
These articles are living documents, i.e. based on readers’ feedback I may add, update or modify their content.

Nextcloud Productivity Platform

So far, I have explored Docker container infrastructure management, shown you how to build an Identity and Access Management service in Docker and used that to make a Video Conferencing platform available to the users of your Slackware Cloud server. Today we are going to explore other means of collaboration and personal productivity.
Some of the topics in the current Episode will cover cloud storage: how do you share your data (documents, music, photos, videos) across your computers with a safe backup copy on your Cloud server? How do you keep track of your activities, read your emails, plan your work, chat with your friends and setup video calls with them? Moreover, how can I achieve all of this without having to depend on the Cloud plaforms that Google, Dropbox, Amazon, Microsoft offer and which seem free but are most certainly not?

The Nextcloud platform which is the main topic of this article, offers a solution to this dilemma. Nextcloud is a spin-off from ownCloud. It was announced in 2016 by the original founder of ownCloud after he left the company because he did not agree to the course ownCloud was going to take. OwnCloud now offers part of its features exclusively as a paid-for subscription model, whereas Nextcloud is fully open source and all features are available to community users as well as paying customers.

The core of Nextcloud is called the Nextcloud Hub, the server product which integrates the three main components Files, Talk and Groupware and which you can host and manage on a server which you own and control. Client programs are available for Linux, Windows and Android platforms that allow you to sync your local files to the server, participate in videoconferences directly from your phone etc.

The goal of setting up Nextcloud on our Slackware Cloud Server is to achieve total control over your data, share these data securely with other people and eliminate dependencies on similar commercial offerings while enjoying the same functionality.

But first a slight detour before we dive into the setup of our Collaboration Platform.
Nextcloud allows for document collaboration in similar fashion to Microsoft Office 365. This is a topic which has its own Episode in the article series: the next one called “Collaborative Document Editing” will center around the integration of Collabora Online Development Edition (CODE) into our Nextcloud Hub.
Collabora is a major contributor to the LibreOffice suite. An online web-based front end to LibreOffice programs was initiated and is being developed by Collabora since 2014, and in essence, Collabora Online is the continued development of the original ‘LibreOffice Online’ code. Collabora moved the repository to github and it is the source used to build CODE, but is also used to create an “enterprise” version which has a paid subscription model. The pre-compiled CODE binaries have a limitation of 10 simultaneously edited documents, but compiling the source yourself will circumvent this artificial limitation.

Preamble

For the scope of this article I will assume that you have a Slackware 15.0 server with IP address “10.10.10.10“. Your own IP address is of course different but your (web)server needs to be accessible online.
Our example server (you need to apply real-life values here of course) has the following configuration:

  • a working Docker environment;
  • Apache httpd configured and running and reachable as “https://darkstar.lan/” with the DocumentRoot directory “/var/www/htdocs/” which is the default location for Apache httpd’s content in Slackware.
  • Keycloak configured and running at “https://sso.darkstar.lan/auth/”;
  • Jitsi Meet configured to use Keycloak for authentication and running at “https://meet.darkstar.lan/“; with the keycloak-jitsi bridge at “https://sso.meet.darkstar.lan/“.
  • PHP version 7.3, 7.4 or 8.0, which is the reason for the Slackware 15.0 requirement – the PHP of Slackware 14.2 is just too old.

Nextcloud Hub II

The Nextcloud Hub II is the new name of the Nextcloud server product which you can download as a single ZIP file and install into your webserver. Nextcloud Hub can be extended with plugins and for that, there is an active App Store. The Nextcloud administrator can search for, install, enable, disable, update, configure and remove these applications from the web-based management console or even from the command-line. This article will discuss some of these applications, in particular the ‘featured apps‘ which are the ones that are supported or developed by Nextcloud GmbH directly.
The core of Nextcloud Hub II consists of the following components:

Files:

Nextcloud Files allows easy access to your files, photos and documents. You can share files with other Nextcloud users, even with remote Nextcloud server instances. When CODE is installed (see the next Episode in this Series) you can even collaborate on documents in real-time with friends, family, team members, customers etc. We have inherent security through data encryption (in transit and on the local file storage) and access control mechanisms, so that only those people with whom you explicitly share your file(s) will be able to access them.

Users store files in their account and this translates to a per-user directory in the host’s filesystem. By default this storage area is not encrypted. If you don’t feel at ease with the idea that unauthorized access to the server potentially exposes userdata to the intruder, the Nextcloud administrator can enable on-disk encryption of all the users’ files. Once encrypted, the userdata can not be decrypted by anyone else than the owner of the files (aka the user) and those with whom files are shared. An encryption key is created per user and the user’s password unlocks that key which is always and only stored on the server. If the user loses their password, they will permanently lose access to their data!
The administrator can configure a ‘recovery key‘ however. You may pose that this allows that administrator to gain access to the userdata, but that’s the other side of the coin of being able to decrypt userdata in the event of loss of the password…

Talk:

Nextcloud Talk offers screensharing, online meetings and web conferencing. The video conferencing capabilities are not yet as strong as Jitsi Meet (in particular it does not scale well to a lot of simultaneous users) but the Talk component is being improved continuously.

Groupware:

Nextcloud Groupware consists of easy to use applications for Webmail, Calendaring and Contacts and is integrated with Nextcloud Files. In webmail you can configure multiple IMAP server accounts, PGP encryption is supported. Calendars can be shared and have Nextcloud Talk integration for video conferences. You can create appointments and define and book resources. Contacts can be grouped, shared with others, and synchronized to and from your phone.
In addition, you can install the featured app ‘Deck‘ which enables you to manage your work with others through private or shared Kanban-style task boards.

Setting up MariaDB SQL server

Nextcloud Hub uses a MariaDB server as its configuration back-end. The users’ files are stored in your host file-system.
You could use SQLite instead… but that is really going to affect the performance of your server negatively if the load increases. In case you have never setup a MariaDB SQL server, I will give you a brief rundown.

MariaDB is part of a full installation of Slackware, and since ‘full install‘ is the recommended install, I will assume you have a mariadb package installed. If not, because you decided to do only a partial installation on your server, be sure to start with an installation of mariadb and its dependencies lz4 and liburing.

  • Create the system tables for the SQL server:
    # mysql_install_db --user=mysql
    Installing MariaDB/MySQL system tables in '/var/lib/mysql' ...
    OK
  • Make the MariaDB boot script executable:
    # chmod +x /etc/rc.d/rc.mysqld
  • Comment the ‘ SKIP="--skip-networking" ‘ line in ‘rc.mysqld‘ because we will use client connections from outside.
  • Execute the boot script (or reboot the machine):
    # /etc/rc.d/rc.mysqld start
  • Perform initial configuration of the database server:
    # /usr/bin/mysql_secure_installation
    Switch to unix_socket authentication [Y/n] n
    Set root password? [Y/n] y
    Remove anonymous users? [Y/n] y
    Disallow root login remotely? [Y/n] y
    Remove test database and access to it? [Y/n] y
    Reload privilege tables now? [Y/n] y

    This script locks down your SQL server properly. It will prompt you to setup the admin (root) password and gives you the option of removing the test databases and anonymous user which are created by default. This is strongly recommended for production servers. I answered “NO” to “Switch to unix_socket authentication” because the Docker containers on our Slackware Cloud server will need to access this MariaDB SQL server over the local network.

You now have MariaDB SQL server up and running, the root (admin) password is set and the root user can only connect to the database from the localhost. It’s ready to setup its first database.
We will manually create the required SQL database  for NextCloud (you might want to insert your own account/password combo instead of my example “nextcloud/YourSecretPassword“). Since we are installing NextCloud on the ‘bare metal‘, NextCloud can communicate with the SQL server via the ‘localhost‘ network address:

# mysql -uroot -p
> CREATE USER 'nextcloud'@'localhost' IDENTIFIED BY 'YourSecretPassword';
> CREATE DATABASE IF NOT EXISTS ncslack CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
> GRANT ALL PRIVILEGES ON ncslack.* TO 'nextcloud'@'localhost';
> FLUSH PRIVILEGES;
> quit;

Configuring Apache and PHP

First of all, we are going to increase the PHP memory limit from the default 128 MB to 512 MB (recommended value) in the file ‘/etc/php.ini‘ or else the more complex operations will fail:

memory_limit = 512M

Don’t forget to enable PHP support in “/etc/httpd/httpd.conf” by un-commenting the line:
Include /etc/httpd/mod_php.conf‘.

Your Apache server needs some directives inside the ‘<VirtualHost></VirtualHost>‘ block that are not enabled by default.
This section needs to be added:

  <Directory /var/www/htdocs/nextcloud/>
    Require all granted
    Satisfy Any
    AllowOverride All
    Options FollowSymLinks MultiViews

    <IfModule mod_dav.c>
      Dav off
    </IfModule>
  </Directory>
  Alias "/localapps" "/opt/netxtcloud/localapps"
  <Directory "/opt/nextcloud/localapps">
    Require all granted
    AllowOverride All
    Options FollowSymLinks MultiViews
  </Directory>

Also, the Apache httpd modules mod_rewrite, mod_headers, mod_env, mod_dir and mod_mime need to be enabled. This is usually done in ‘/etc/http/httpd.conf‘.

Configuring local storage

We are going to maintain all of the Nextcloud users’ personal data separately from the server code and even outside of the webserver document root. Nobody should be able to access your files through a possible hole in your webserver.

Also, when the Nextcloud administrator (you) is going to extend the server’s functionality by installing additional apps, you will want these apps to be installed outside of the Nextcloud application directory. This allows for a clean upgrade process if we want to install a newer version in the future. The “/opt/nextcloud/” will be the root directory for all of this. The httpd user account “apache” needs to own these files.

Let’s start with creating the userdata directory:

#  mkdir -p /opt/nextcloud/data
#  chown apache:wheel /opt/nextcloud/data

And the directory where the add-ons will be installed:

# mkdir -p /opt/nextcloud/localapps
# chown apache:wheel /opt/nextcloud/localapps

To the Apache httpd VirtualHost configuration you should add an  ‘Alias‘ statement which points the webserver “/localapps” path component to the filesystem location “/opt/nextcloud/localapps“. This line was  already mentioned in the Apache configuration snippet further up:

Alias "/localapps" "/opt/netxtcloud/localapps"

Installing the Nextcloud Hub

We will download the latest stable release from their server installation page.
At the time of writing, 23.0.0 is the latest available so:

# cd ~
# wget https://download.nextcloud.com/server/releases/nextcloud-23.0.0.zip
# unzip -n nextcloud-23.0.0.zip -d /var/www/htdocs/
# chown -R apache:wheel /var/www/htdocs/nextcloud/

We have already created the SQL database, so we can immediately continue with the Web setup. Point your browser at http://darkstar.lan/nextcloud/ :

This is where you will define the account and password for the Nextcloud administrator. It will be the only account with local credentials (stored in the SQL backend). All  future Nextcloud user authentication & authorization will be configured and managed via the Keycloak IAM program. The green text snippets match with configuration settings documented higher up in this article.

  • I will use the name “admin” for the account and give it a secure password.
  • Storage & Database:
    • Data Folder: “/opt/nextcloud/data
    • Database: MySQL/MariaDB
    • Database user: “nextcloud
    • Database password: “YourSecretPassword
    • Database name: “ncslack
    • Localhost: add the MariaDB port number so that it reads “localhost:3306”
  • Install recommended apps: Calendar, Contacts, Talk, Mail & Collaborative editing: ensure that this box is checked (note that the Collaborative Editing program – CODE – download will probably fail but we will install it as an external application later):

TIP: I experienced that when the password fields are set to “show password”, the installation will refuse to continue.

Click “Finish” to kick off the Nextcloud setup.

This configuration process ends with some screens that will show off the capabilities of the programs, you can either close these immediately (the “X” top right) or click through them until the end. You will end up in your Nextcloud dashboard:

Post-configuration

After installation and initial configuration we are now going to tune the server.

Pretty URLs

A Nextcloud URL looks like “http://localhost/nextcloud/index.php/apps/dashboard/” and I want to remove the “index.php” string which makes the URLs look nicer. Check the official documentation.

  • Edit “./config/config.php” file in the nextcloud directory. Add the following two variables right before the last line which goes like “);“:
    ‘overwrite.cli.url’ => ‘https://darkstar.lan/nextcloud’,
    ‘htaccess.RewriteBase’ => ‘/nextcloud‘,
  • We are going to use the NextCloud command-line interface ‘occ‘ (here it shows its heritage; ‘occ‘ stands for ‘Own Cloud Console‘) in order to apply the changes in ‘config.php‘ to the ‘.htaccess‘ file in the NextCloud installation directory.
    The ‘occ’ command needs to be run as the httpd user (‘apache‘ in the case of Slackware):
    # sudo -u apache php -d memory_limit=512M /var/www/htdocs/nextcloud/occ \
    maintenance:update:htaccess
    .htaccess has been updated
    Note that I have not been able to get this to actually work! Pointers with a fix for pretty URLs are welcome!

Server scan

You can run a “server scan” as admin user via “Settings > Administration > Security & Setup Warnings” to see if Nextcloud has suggestions on improving performance and functionality of the server.
In my case, it reports that a number of database indexes are  missing, and that the following commando will fix this:

# sudo -u apache php /var/www/htdocs/nextcloud/occ db:add-missing-indices

This scan will also point out performance issues about which I will share more details, below in “Tuning server performance” section.

Cron maintenance

It is advised to install a cron job which runs as the “apache” user, and performs maintenance every 5 minutes. In Nextcloud as the admin user, you configure the “Cron” maintenance type via “Settings > Administration > Basic Settings > Background Jobs“.
This needs to be accompanied by an actual cron job definition on the Slackware server; so this is the command that I added to the crontab for “apache“:

# crontab -u apache -l
# Run maintenance for NextCloud every 5 minutes:
*/5 * * * * /usr/bin/php -f /var/www/htdocs/nextcloud/cron.php

Install add-on applications outside of Nextcloud directory

We have already created a ‘/opt/nextcloud/localapps‘ directory with the intention of using that location for the installation of all the apps that we want to add to our Hub.
In order to enable a separate application installation path, you need to add the following lines to ‘./config/config.php‘:

'appstoreenabled' => true,
'apps_paths' => array(
    array(
    'path'=> OC::$SERVERROOT . '/apps',
    'url' => '/apps',
    'writable' => false,
  ),
  array(
    'path'=> '/opt/nextcloud/localapps',
    'url' => '/localapps',
    'writable' => true,
  ),
),

Note that if you get an error from external applications when they attempt to parse the ‘config.php’ file of NextCloud which looks like “Expected boolean literal, integer literal, float literal, string literal, ‘null’, ‘array’ or ‘[‘”, you may have to replace:
'path'=> OC::$SERVERROOT . '/apps',
with
'path'=> '/var/www/htdocs/nextcloud/apps',

Tuning server performance

Memory cache

The main optimizations which will boost your server’s performance and responsiveness are related to memory caching and transactional file locking.

You can address these both by installing redis (an in-memory key-value memory store) and php-redis (PHP extension for redis) as Slackware packages from my repository:

After installing redis, configure it correctly for Nextcloud.

  • Enable the php redis extension by editing ‘/etc/php.d/redis.ini‘ and removing the semicolon so that you get the following line:
    ; Enable redis extension module
    extension=redis.so

    Optionally add these lines to tune its performance:
    ; Should the locking be enabled? Defaults to: 0.
    redis.session.locking_enabled = 1
    ; How long should the lock live (in seconds)?
    ; Defaults to: value of max_execution_time.
    redis.session.lock_expire = 60
    ; How long to wait between attempts to acquire lock, in microseconds?.
    ; Defaults to: 2000
    redis.session.lock_wait_time = 10000
    ; Maximum number of times to retry (-1 means infinite).
    ; Defaults to: 10
    redis.session.lock_retries = -1
  • Make the redis daemon listen at a UNIX socket as well as a TCP port, uncomment these lines in the “/etc/redis/redis.conf” configuration file:
    unixsocket /var/run/redis/redis.sock
    unixsocketperm 660
  • Make the init script executable and start it manually (it gets added to rc.local so it will start on every boot from now on):
    # chmod +x /etc/rc.d/rc.redis
    # /etc/rc.d/rc.redis start

Enable the use of redis in Nextcloud’s main configuration file “/var/www/htdocs/nextcloud/config/config.php” by adding the following block:

'memcache.locking' => '\\OC\\Memcache\\Redis',
'memcache.local' => '\\OC\\Memcache\\Redis',
'memcache.distributed' => '\\OC\\Memcache\\Redis',
'redis' => 
array (
    'host' => '/var/run/redis/redis.sock',
    'port' => 0,
),

Finally, allow the “apache” user to be able to read the Redis socket by adding the user to the “redis” group:

# gpasswd -a apache redis

… and restart the Apache httpd service.

PHP OPcache

OPcache is a PHP extension for Apache httpd which stores (pre-)compiled PHP script bytecode in memory. This speeds up the performance of PHP-based applications like Nextcloud, because it reduces or eliminates the need to load PHP scripts from disk and parse them every time they are called.
Slackware’s PHP has opcache enabled in “/etc/php.ini“. Relevant settings are:

opcache.enable=1
opcache.memory_consumption=128
opcache.max_accelerated_files=10000
opcache.revalidate_freq=200

These are default values for Slackware and therefore they are commented-out in the “php.ini” file but you can validate that they are enabled via the command:

# php -i |grep opcache

If you find that OPcache is disabled, you should fix that ASAP.

Check your security

Nextcloud offers a neat online tool that connects to your Nextcloud instance and performs a series of security checks, and will advise you in case you need to improve on your server security: https://scan.nextcloud.com/ .

Commandline management

The web-based management interface for the “admin” user is ‘https://darkstar.lan/nextcloud/index.php/settings/user‘ but a lot of administration tasks can also be done directly from the Slackware server’s command prompt (as root) using the “Own Cloud Console” program ‘occ‘ I already briefly touched on earlier in this article.

Some examples:

Install an application, say “richdocumentscode” which is a built-in low-performance version of CODE (Collabora Online Development Edition):

# sudo -u apache php -d memory_limit=512M /var/www/htdocs/nextcloud/occ app:install richdocumentscode

App updates can be done on commandline too:

# sudo -u apache php -d memory_limit=512M /var/www/htdocs/nextcloud/occ app:update --all

Remove an app:

# sudo -u apache php -d memory_limit=512M /var/www/htdocs/nextcloud/occ app:remove richdocumentscode

Get the list of possible occ command options:

# sudo -u apache php -d memory_limit=512M /var/www/htdocs/nextcloud/occ app:list

Integration with Keycloak IAM

The server is running nicely, and it is time to invite users. All our users will be managed by our Keycloak IAM program.
To integrate Keycloak into Nextcloud we first create a “Client ID” for Nextcloud in our Keykloak admin console and copy the relevant secret bits from that ID into Nextcloud. Nextcloud will contact Keycloak with a URL that will ebable login for the users in our “foundation” realm, i.e. the realm which we created when we setup Keycloak.

Keyloak:

  • Login to the Keycloak Admin Console, https://sso.darkstar.lan/auth/admin/ .
    • Under ‘Clients‘, create a new client:
      Client ID‘ = “nextcloud
      Root URL‘ = “darkstar.lan/nextcloud
    • Save.
    • In the ‘Settings‘ tab, change:
      Access Type‘ = “confidential” (default is “public”)
    • Save.
    • In the ‘Credentials‘ tab, copy the value of the ‘Secret‘, which we will use later in Nextcloud: “61a3dfa1-656d-45eb-943a-f3579a062ccb” (your own value will of course be different).

Nextcloud:

  • Login to Nextcloud as the admin user: https://darkstar.lan/nextcloud
    • In ‘Profile > Apps‘, install the ‘Social Login‘ app.
  • Configure Nextcloud’s social login to use Keycloak as the identity provider
    • Make sure ‘Disable auto create new users‘ is UN-checked because every user logging in via Keycloak for the first time must automatically be created as a new user.
    • DO check ‘Prevent creating an account if the email address exists in another account‘ to ensure that everyone will have only one account
    • Add a new ‘Custom OpenID Connect‘ by clicking on the ‘+‘:
      ‘Title’ = “keycloak”
      ‘Authorize url’ = “https://sso.darkstar.lan/auth/realms/foundation/protocol/openid-connect/auth”
      ‘Token url’ = “https://sso.darkstar.lan/auth/realms/foundation/protocol/openid-connect/token”
      ‘Client id’ = “nextcloud
      ‘Client Secret’ = “61a3dfa1-656d-45eb-943a-f3579a062ccb” (this is the value you obtained earlier in the Keycloak Client definition)
      ‘Scope’ = “openid”
      ‘Default group’ = “none”
    • ‘Groups claim’ = “nextcloud” (optional setting, make sure you create a group “nextcloud” in Keycloak’s “foundation” realm and have added your future Nextcloud users as members of this group).
    • Also optional, ‘Add group mapping‘ can automatically arrange that the Keycloak group “nextcloud” is mapped to Nextcloud group, e.g. called “My social circle” with which you can limit access in Nextcloud to only those apps that you approved.
    • Save.

Your Nextcloud login page will now additionally offer a ‘Login with Keycloak Authentication” option. Clicking this will redirect you to a Keycloak authentication page. Screenshots of how this looks exactly can be found further down in the section “Nextcloud clients“.
After successful login and authorization with an existing Keycloak user account you will be returned to Nextcloud and logged in. If this was the user’s first login to Nextcloud using Keycloak credentials, Nextcloud will create an internal user account which is linked to the Keycloak credentials.

Integrating Jitsi Meet

The integration of an embedded Jitsi Meet window into Nextcloud requires some configuration in Apache httpd (for the embedding) and in Nextcloud itself (securing the intercommunication via a JSON Web Token).

Apache:

Add the following to your httpd global configuration, for instance to ‘/etc/httpd/httpd.conf‘ (the parts in green need to be replaced by your real-life hostnames of course):

# Mitigate the risk of "click-jacking" (other sites embedding your pages
# and adding other, possibly malicious, content)
# See https://developer.mozilla.org/en-US/docs/HTTP/X-Frame-Options
Header always append X-Frame-Options SAMEORIGIN
# And allow embedding of Jitsi Meet in Nextcloud (add any URL for which you would also allow embedding):
RequestHeader set X-HTTPS 1
Header always set Content-Security-Policy "frame-ancestors 'self';"
Header always set Content-Security-Policy "frame-ancestors https://darkstar.lan https://sso.darkstar.lan https://meet.darkstar.lan ;"

Followed by a restart of Apache httpd.

Nextcloud:

  • Install the “Jitsi Integration” app as the admin user via ‘Profile > Apps
  • Go to  ‘Profile >Settings > Jitsi’
    • ‘Server URL’: enter “https://meet.darkstar.lan
    • ‘JWT Secret’: enter “NmjPGpn+NjTe7oQUV9YqfaXiBULcsxYj” (this is the JWT token which you entered as the value for ‘JWT_APP_SECRET‘ variable in the ‘.env‘ file of  our ‘docker-jitsi-meet‘  instance, see the previous Episode on Video Conferencing for details)
    • JWT App Id‘: enter “jitsi” (which is the value of the  ‘JWT_APP_ID‘ variable in that same ‘.env‘ file)
    • Save

That’s it!
Users will now find a ‘Conferences‘ icon in the application bar at the top of their Nextcloud home. Clicking it will open an embedded Jitsi video conferencing window.

One obvious advantage to using this NextCloud embedded Jitsi Meet is that the resulting Meet URLs are impossible to guess, they will not mention the meeting room name but instead use a UUID like ‘https://meet.darkstar.lan/06135d8e-5365-4a6f-b31b-a654d92e8985‘.
If you compare this to the regular Jitsi Meet at ‘https://meet.darkstar.lan/‘, your meeting room with the name ‘roomname‘ would be accessible as ‘https://meet.darkstar.lan/roomname‘ which is a lot easier to guess… un-desirable if you want to hold private meetings.

Adding new apps

I encourage you to check out the Nextcloud App Store. There’s a wealth of cool, useful and fun applications to be found there.

Some of the apps that I installed are: GPXPod (visualize your GPX routes); Carnet (powerful note-taking app); Music (listen to your local collection or tune into online streams); PhoneTrack (keep track of your phone, needs the Android app to be installed too); Element (messenger app with bridges to Matrix and Libera.Chat for instance); Cookbook (maintain your own recipe database and easily import new recipes from external websites using only the URL to the recipe), etc…

Adding client push daemon

Extremely useful is Push update support for the desktop app. The 21 release of Nextcloud introduced a ‘high performance backend‘ for filetransfers. This increases the speed of filetransfers substantially, but it needs a couple of things to make it work.

  • The worker app is called “Client Push” and needs to be installed on your server from the Nextcloud App Store. Once the app is installed, the push binary still needs to be setup. The README on github contains detailed setup instructions. For the Slackware way, read on.
  • You need to have the redis package installed and the redis server needs to be started and running. We already took care of this in the section ‘Performance tuning‘.
  • Slackware, Apache and Nextcloud need to be configured for redis and the notify_push daemon.

Slackware:

The notify_push binary gets installed as ‘/opt/nextcloud/localapps/notify_push/bin/x86_64/notify_push‘. Hint: this is 64-bit only. This binary needs to run always, so the easiest way is to add a Slackware init script and call that in ‘/etc/rc.d/rc.local‘.

The init script can be downloaded from my repository, but it’s listed here in full as well. I highlighted the texts in green that are relevant. Save it as ‘/etc/rc.d/rc.ncpush‘ and make it executable:

#!/bin/bash
# Description: Push daemon for NextCloud clients.
# Needs: redis php-fpm mariadb
# Written by: Eric Hameleers <alien@slackware.com> 2021
daemon=/usr/bin/daemon
description="Push daemon for Nextcloud clients"
pidfile=${pidfile:-/var/run/nextcloud/notify_push.pid}
ncconfig=${ncconfig:-/var/www/htdocs/nextcloud/config/config.php}
command=${command:-/opt/nextcloud/localapps/notify_push/bin/x86_64/notify_push}
command_user=${command_user:-apache}
command_args="--bind 127.0.0.1 --port 7867 $ncconfig"

[ ! -x $command ] && exit 99
[ ! -f $ncconfig ] && exit 99

RETVAL=0

start() {
  if [ -e "$pidfile" ]; then
    echo "$description already started!"
  else
    echo -n "Starting $description: "
    mkdir -p $(dirname $pidfile)
    chown $command_user $(dirname $pidfile)
    chmod 0770 $(dirname $pidfile)
    $daemon -S -u $command_user -F $pidfile -- $command $command_args
    RETVAL=$?
    [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$(basename $command)
    echo "- done."
  fi
}
stop(){
  echo -n "Stopping $description: "
  kill -TERM $(cat $pidfile)
  RETVAL=$?
  [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$(basename $command)
  echo "- done."
}
restart(){
  stop
  start
}
condrestart(){
  [ -e /var/lock/subsys/$(basename $command) ] && restart
}
status() {
  pids=$(cat $pidfile 2>/dev/null)
  if test "$pids" ; then
    echo "$description is running."
    ps up $pids
  else
    echo "$description is stopped."
  fi
}
# See how we were called.
case "$1" in
start)
  start
  ;;
stop)
  stop
  ;;
status)
  status
  ;;
restart)
  restart
  ;;
condrestart)
  condrestart
  ;;
*)
  echo "Usage: $0 {start|stop|status|restart|condrestart}"
  RETVAL=1
esac
exit $RETVAL
# ---

The script is then called on boot by adding the following to your server’s ‘/etc/rc.d/rc.local‘:

if [ -x /etc/rc.d/rc.ncpush ]; then
  # Start Nextcloud Client Push Daemon
  echo "Starting Nextcloud Client Push Daemon: /etc/rc.d/rc.ncpush start"
  /etc/rc.d/rc.ncpush start
fi

Apache:

Setup the bits of Apache configuration for your webserver. The following block of configuration needs to be added:

ProxyPreserveHost On
ProxyTimeout 900
SSLProxyEngine on
RequestHeader set X-Forwarded-Proto "https"

# Setup a reverse proxy for the client push server
# https://github.com/nextcloud/notify_push/blob/main/README.md :
<Location /push/ws>
    ProxyPass ws://127.0.0.1:7867/ws
</Location>
<Location /push/>
    ProxyPass http://127.0.0.1:7867/
    ProxyPassReverse http://127.0.0.1:7867/
</Location>

# Do not forget WebSocket proxy:
RewriteEngine on
RewriteCond %{HTTP:Connection} Upgrade [NC]
RewriteCond %{HTTP:Upgrade} websocket [NC]

You know where to add the above.

Nextcloud:

Add these lines to “./config/config.php“. Relevant pieces are highlighted in green, you should of course change that into your own Internet IP address:

‘trusted_proxies’ => [‘10.10.10.10‘],
‘forwarded_for_headers’ => [‘HTTP_X_FORWARDED’, ‘HTTP_FORWARDED_FOR’, ‘HTTP_X_FORWARDED_FOR’],

Piecing it all together:

Preparations are complete after you have restarted Apache httpd and started the ‘rc.ncpush‘ script. Redis should also be running.
Now we can finally enable the app we installed in Nextcloud:

# sudo -u apache php -d memory_limit=512M /var/www/htdocs/nextcloud/occ app:enable notify_push

Setup the connection between the app and the daemon:

# sudo -u apache php -d memory_limit=512M /var/www/htdocs/nextcloud/occ notify_push:setup https://darkstar.lan/push/
> redis is configured
> push server is receiving redis messages
> push server can load mount info from database
> push server can connect to the Nextcloud server
> push server is a trusted proxy
> push server is running the same version as the app
configuration saved

Upgrading to newer release

Here is an example of the steps to take when you upgrade from one major release to the next (for instance you want to upgrade from 23 to 24).

First, download and extract the release tarball, and set the file ownership to the ‘apache‘ user:

# cd ~
# wget https://download.nextcloud.com/server/releases/nextcloud-24.0.0.tar.bz2
# tar xf nextcloud-24.0.0.tar.bz2
# chown -R apache:wheel /root/nextcloud

Disable the server-maintenance cronjob of the “apache” user before continuing, for instance by adding ‘#” in front of the cron commandline!

# crontab -u apache -e
# crontab -u apache -l
# Run maintenance for NextCloud every 5 minutes:
####*/5 * * * * /usr/bin/php -f /var/www/htdocs/nextcloud/cron.php

Stop the Apache httpd:

# /etc/rc.d/rc.httpd stop

Rename the old “/var/www/htdocs/nextcloud/” installation directory and move the new ‘nextcloud‘ directory in its place:

# mv -i /var/www/htdocs/nextcloud /root/nextcloud.orig
# mv -i /root/nextcloud /var/www/htdocs/nextcloud

Copy your Nextcloud configuration into the new directory (this should only overwrite the ‘config.sample.php‘ file):

# cp -ia /root/nextcloud.orig/config/* /var/www/htdocs/nextcloud/config/

Start the Apache httpd again:

# /etc/rc.d/rc.httpd start

Start the commandline updater. This MUST be done from within the Nextcloud installation directory:

# cd /var/www/htdocs/nextcloud/
# sudo -u apache php -d memory_limit=512M occ upgrade

Now, re-enable the cronjob for user “apache“.
Then re-create the now again missing database indices:

# sudo -u apache php /var/www/htdocs/nextcloud/occ db:add-missing-indices

Stable versus beta channels

Nextcloud offers “Stable” and “Beta” channels of its software. From time to time, new functionality becomes available in the Beta channel that you really want to use.
As the admin user, you can configure your preferred release channel in “Settings > Administration > Overview > Version > Update Channel” if you have installed Nextcloud from a release tarball like we did.

NOTE that you can only upgrade to a newer versionSkipping major versions when upgrading and downgrading to older versions is not supported by Nextcloud.
For instance, if you went via ‘Beta‘ to 24.0.0rc4 and ‘Stable‘ is still on 23.0.5, you have to wait with further upgrades until 24.0.0 or later becomes available in the ‘Stable‘ channel.

Nextcloud makes new versions incrementally available to user installations in the Stable channel which means it can take a while before your server alerts you that a new release is available.

Nextcloud clients

Nextcloud mobile and desktop clients are available from https://nextcloud.com/clients/ .

Client applications can keep your files synchronized between Nextcloud server and your desktop or phone; can manage your passwords that you store securely on the server; can manage your calendar, setup chat and video connections to other users of your server; and more.

The desktop file-sync client (nextcloud-client) is available in my own repository as a package and on SlackBuilds.org as a build script (but the SBo version is actually still the old OwnCloud mirall client). Its GUI is Qt5-based. This is a free alternative for Dropbox and the likes!

When you start the nextcloud-client desktop application for the first time, you will go through an initial setup. The client needs to get configured to connect to your Nextcloud server:

After clicking “Log in to your Nextcloud” you can enter the URL at which your server is available:

The client will open your default browser (in case of my KDE Plasma5, this was Konqueror) and ask you to switch to that browser window to logon to your Nextcloud:

You can click “Copy Link” so that you  can use another browser if you are not happy with the default browser choice. The next steps take place inside that browser window:

You need to login with your Nextcloud user account. In this dialog we click on “Log in with Keycloak Authentication” instead of entering an account/password into the top entry fields – remember, only the admin user has an account with local credentials:

You will probably recognize the familiar Keycloak Single Sign On dialogs from the previous Episode (Video Conferencing):

This account has 2-Factor Authentication (2FA) enabled:

After succesful login, the Nextcloud server wants to get your explicit permission to grant access for the desktop client to your server data:

After you click “Grant access” the client will finally be able to connect to your data and start syncing:

You get a choice of the local desktop directory to synchronize with your server data – by default this is ‘~/Nextcloud/‘:

The client docks into the system tray from where you can access your files and manage the sync. The desktop client integrates nicely with KDE’s Dolphin and Konqueror, and shows the sync status of the ‘~/Nextcloud/‘ directory (and the files in it) with a badge – similar to what Dropbox does.
All files inside ‘~/Nextcloud/‘ will have a right-mouseclick context menu offering some filesharing options and the possibility to open the serverlocation of the file in your webbrowser.

Fixes

To end this Episode, I will collect the fixes that were necessary to make Nextcloud do what I wanted it to do.

Enable geolocation in the NextCloud phonetrack app by applying this patch:

# diff -u lib/public/AppFramework/Http/FeaturePolicy.php{.orig,}

Slackware 15.0 has been released on 2022-02-02

Pick your favorite quote for today!

What would you do if you were stuck in one place,
and every day was exactly the same and nothing that you did mattered?

… or rather:

Welcome to Adventure!!  Would you like instructions?

Wed Feb 2 22:22:22 UTC 2022
Slackware 15.0 x86_64 stable is released!

Another too-long development cycle is behind us after we bit off more than
we could chew and then had to shine it up to a high-gloss finish. Hopefully
we've managed to get the tricky parts out of the way so that we'll be able
to see a 15.1 incremental update after a far shorter development cycle.

I honestly kept my breath and have had some difficulty believing that this would eventually really happen, but yet here it is. Slackware 15.0 stable! Released yesterday and available on mirrors across the globe today.
I am fiercely proud of Patrick Volkerding who has again showed all of us that the oldest actively maintained Linux distribution is more than a rolling release for Linux enthusiasts.
The latest stable release 15.0 is packed with applications for both desktop and server usage. It is truly a modern Linux platform that power users can and should embrace as their daily driver.

I will share with you some of the highlights and particulars of the development process between the release of Slackware 14.2 (the previous stable) and the new 15.0.

  • With five years and seven months in the making, this has been the largest interval between stable releases.
  • We said ‘farewell’ to the Slackware Store and goodbye to printed DVD and CDROM sets.
    A major reason for this dragged-out development cycle is the realization that for a long time, Pat and family have been deprived of substantial amounts of revenue which the people of The Store reaped through the sales of Slackware installation media, clothing and other paraphernalia. The truth was shared by Pat in a post on LinuxQuestions and resulted in a long-running thread discussing how the community could help with the funding: https://www.linuxquestions.org/questions/slackware-14/donating-to-slackware-4175634729/ .
    Luckily a new means of securing an income for Pat was established through Patreon, which allows Pat to focus again on his Slackware distro. After all, Slackware is his only source of income; the rest of the coreteam have regular day jobs and we don’t get (nor want) any part of the revenue.
  • A ChangeLog.txt of roughly 40,000 lines makes the process of “slackpkg install-new” (churning through all that text) to find all those added packages a long and painful one.
  • The Slackware 15.0 core distribution consists of 1590 packages, a 19% increase from the 1332 packages in Slackware 14.2 core (i.e. everything not in ./extra or in ./testing).
    A lot of packages have been removed (276), many of those belong to KDE4 and 82 of them are the old language packs. You won’t miss a thing there because language support in Plasma5 is now included in all the application packages.
    If you look at the number of packages that have been added to the distro (i.e. did not exist in Slackware 14.2), that’s an impressive 534.
  • The compressed size of these packages went up from 2.4 GB to 3.0 GB. Uncompressed and installed onto your computer, the difference will be significantly larger. The recommended disk space needed for a full installation, increases from 9+ GB (Slackware 14.2) to 16+ GB.

So what about that exciting content you can find in the new 15.0 release?

  • Slackware 15.0 installs Linux kernel 5.15.19.
  • The kernels all have preemption enabled and you can configure your bootloader for full, dynamic or no preemption.
  • The installer properly supports installing to NVMe disks and has improved support for installing on UEFI platform.
  • Slackware still supports 32bit hardware platforms and is one of the few relevant Linux distros that do so today.
    Both the 64bit and the 32bit distro are built from a single source tree.
  • Collaboration with smart people on the LinuxQuestions.org forum resulted in the ability for Slackware to be reliably built from scratch these days. Thanks in particular to worsel and nobodino. The latter maintains his efforts in a git repository from which Slackware has borrowed several patches. Slackware itself has a ‘master build script’ called make_world.sh and Patrick keeps a log of everything that “fails to build from source” aka the FTBFSlog files which you can find in the source-directory root of every package series. Nothing in the distro fails to build from source right now, which is awesome and a definite change from previous stable  releases.
  • In ./source/installer you find the complete sources to easily rebuild the Slackware installer from scratch.
  • ConsoleKit2 was replaced with elogind as the session/seat manager. Elogind is a standalone version of the logind code in systemd and independently maintained at https://github.com/elogind/elogind .
  • FFmpeg and Lame have been added to the distro, yay! Also, it includes SDL2, speex, opus, fluidsynth.
  • A new command-line ISO creation tool to supplement cdrtools was added: xorriso.
  • Python3 was introduced but Python2 stuff remains available and is still the default python. Its most relevant modules have been bundled in a compatibility package.
  • Postfix has been added and Sendmail moved to ./extra where it still receives upgrades. Lucky me, I still prefer and use Sendmail on my boxes.
  • Dovecot is the powerful new IMAP and POP3 server, replacing the old imapd and ipop3d.
  • The Qt4 graphical toolkit has been removed and Qt5 came in its place.
  • KDE 4 (which was already abandoned at the release of Slackware 14.2) has been replaced with KDE Plasma5. More specifically, with Frameworks 5.90, Plasma 5.23.5 and Applications 21.12.1, meaning the very latest versions; all released this January 2022. This is topped with some cool additional Plasma5 applications like the Calligra office suite, Krita vector drawing program, Digikam photo management, KMymoney personal finance management, the Chromium- and Qt5-based webbrowser Falkon and Kyle LaTeX editor (and then some). And of course KDevelop.
  • The latest XFCE 4.16 is included and it’s a very nice step-up from the version of Slackware 14.2.
  • Wayland 1.20.0 is available as alternative to the venerable X.Org 1.20.14 which is still the default graphical display system.
  • The latest Mesa and Vulkan libraries are installed and GLvnd (the GL Vendor-Neutral Dispatch library) ensures that for instance NVIDIA’s binary driver is a breeze ti install and will not overwrite any system files.
  • Pulseaudio has competition from Pipewire which has been added to the distro and ships with a configuration that can mostly replace pulseaudio with this new low-latency audio server.
  • The whole build toolchain has seen a thorough refresher, with glibc 2.33, GCC 11.2.0 and LLVM 13.0.0 and the addition of Rust which is now at 1.58.1. Also essential tools that are part of modern-day software compilation like meson, ninja, scons and icecream are new in Slackware 15.0.
  • … and there’s a lot of other stuff that you have to find out for yourself.

Using Slackware

All in all, when you install Slackware 15.0 on your computer you will be able to work in graphical desktop environments and using tools that are on par with all the big distros. When looking for software that is not part of the core distro you can turn to slackbuilds.org (SBo) which is a curated platform for Slackware package build scripts. Tools like sbopkg, sbotools and slpkg will assist you in automating the build- and dependency resolving process when using these scripts from SBo.
Third-party package repositories are also available to quickly install binary packages if you do not trust yourself when compiling from source. You can think of my own alien and restricted packages but also Robby Workman’s package repository or the SlackOnly collection of packages that have been pre-compiled for you out of all the SBo scripts.
Slackware’s own slackpkg package manager which only deals with official Slackware packages can be extended with the plugin slackpkg+ if you want to be able to easily manage a mix of official and 3rd-party packages using a single tool.

Slackpkg with the slackpkg+ plugin also supports managing a multilib installation (i.e. a 64bit Slackware OS which is capable of running and compiling 32bit software). With multilib, running the Steam gaming platform is fully supported on your 64bit Slackware, and Steam applications run as fast on Slackware (or faster) than on Windows.

I hope you are all as excited about this new release of Slackware Linux as I am, and I hope you will have a lot of fun using it. Of course, those of you who have been running the ‘bleeding edge’ all the time, aka Slackware-current, can keep doing that. The Slackware-current tree is still there and it will now focus on post 15.0 development towards the next stable release.

Upgrading from 14.2

People upgrading from Slackware 14.2 have multiple options. You should definitely read the CHANGES_AND_HINTS file to get a good picture of the many package additions and removals. The UPGRADE.TXT file is an invaluable source if you want to perform a manual upgrade.
The Slackware Documentation Project contains an article called “upgrading Slackware to a new release“. It describes how to use the slackpkg tool (which is part of Slackware) to perform the upgrade with a large degree of automation.

Still, it is good to be aware that Slackware moved from ConsoleKit2 to elogind and one thing will be immediately obvious if you start an X session after upgrade and reboot:

With elogind as the session/seat manager instead of ConsoleKit2, if you run ‘startx’ or ‘startkwayland’ at the console, you won’t see a VT (virtual terminal) switch. In the past, your console TTY would usually be tty1 but your graphical session would start on tty7 and you would automatically be switched from tty1 to tty7. This is no longer true – the graphical session will re-use your console TTY.

You can read more details about the implications of the switch to elogind in my 2020 blog post here on Alien Pastures.

Get Slack

Download your official ISO images from any of the Slackware mirrors. We use mirrorbrain to ensure that a visit to mirrors.slackware.com will lead you to a server that is near to you.

Support Slackware

Please consider supporting Patrick and his family by visiting his Patreon Page, choosing a membership category and becoming a Patron. If you can spare a dollar or so per month, it will help keeping this unique distribution alive. All that money goes only to Pat.
If you are longing for the stuff that The Store used to sell, you can have a look at this CafePress URL which is Pat’s. Anything you buy there generates some money for him: so on you go to Patrick’s CafePress Shop.
Don’t fall for the fakes (several others on Cafepress sell clothing and gear with Slackware’s logo on them)!

Give Slackware a test-drive

Has the article made you curious or interested but you don’t yet feel comfortable installing Slackware on your computer?
We’ve got you covered!
There’s a Slackware Live Edition waiting for you. It is the same Slackware 15.0 but it will run entirely from a USB stick, won’t touch your harddisks and you don’t have to install anything.
Unlike Slackware itself, the Slackware Live Edition supports Secure Boot but you’ll have to enroll the liveslak certificate into your computer’s MOK first.
And if you do want to install Slackware after seeing the Live Edition, there’s a “Install Slackware” icon right there on the graphical desktop, which you can click (and use the password “live“!) to run through a slightly modified but still very familiar Slackware setup program (called ‘setup2hd‘ in the Live Edition).

Get the ISO for Slackware Live Edition 15.0 here: https://slackware.nl/slackware/slackware-live/slackware64-15.0-live/ (rsync via rsync://slackware.nl/mirrors/slackware/slackware-live/slackware64-15.0-live/). Instructions about installing the ISO to a USB stick and using Slackware Live can be found at https://liveslak.org/ or https://docs.slackware.com/slackware:liveslak#enduser_documentation .

Choosing development or stable

Slackware comes in two flavors:

  1. The stable releases (14.2 and 15.0 being the most recent ones) which get regular security updates but no changes in functionality;
  2. And the development release called ‘slackware-current’ which has a lot of activity with sometimes daily updates, new functionality and basically being there for all of us to test and find the bugs.

Note that the designation ‘-current‘ confuses some people who interpret “current” as “latest stable“. It is not!

Are you running ‘-current’ but want to switch to Slackware 15.0 and enjoy a stable experience with regular security updates but without the hassle of daily upgrades and occasional breakage? It’s as easy as opening the mirror list (/etc/slackpkg/mirrors) for your package manager slackpkg, and selecting a Slackware 15.0 mirror instead of a Slackware-current mirror.
To give an example: I myself would change the single un-commented line in that file  “http://slackware.nl/slackware/slackware64-current/” to  “http://slackware.nl/slackware/slackware64-15.0/“, and then run “slackpkg update ; slackpkg install-new ; slackpkg upgrade-all“. Now my computer is fully up-to-date with Slackware 15.0 and ready to receive future security upgrades.

Note that if you are not only interested in security updates but actually want to be able to run new software all the time, then the development release  “Slackware-current” is still the better option for you; but you need to be able to fix the occasional breakage which is inherent to walking the bleeding edge. If you want to switch from a stable release to -current, the process is simular to the example above: change the mirror line in “/etc/slackpkg/mirrors” to the URL of a slackware-current repository and be sure to read the documentation.

Looking forward

Things I hope to see in that next release post 15.0:

  • Out-of-the-box support for SecureBoot
  • The switch from Elilo to Grub as the default bootloader for UEFI platforms
  • Getting rid of the huge kernel and automatically generate and use initrd.gz images with generic kernels in Lilo and Grub
  • Full integration of Pipewire as an audio/video server replacing Pulseaudio and making Jack2 superfluous
  • A basic firewall as part of the initial installation

Not all of that will probably be achievable, but we’ll see…

In memoriam

A long-standing member of the Slackware core team passed away during the development process towards Slackware 15.0. Erik Jan Tromp (alphageek) would have loved to have been able to witness the release of Slackware 15.0 but circumstances decided otherwise. We said goodbye to him in March 2020.
He will be remembered fondly.
