phpBB: Upgrade fails (timeout) – solution and how to update on the CLI

Filed under: PHP,Server Administration — Tags: , , , , , , , — Christopher Kramer @ 10:46

So if you are getting a Timeout when updating phpBB to 3.2.2, it tells you to either increase the maximum time limit or do the update on the CLI.

How to update on the CLI

Of course, this requires that you have access to the CLI.

  • On the CLI, go into the install folder of phpBB
  • Create a file named config.yml that contains this: 
    updater:
    type: db_only
  • Make sure the above file does not end with newlines
  • Run: 
    php ./phpbbcli.php update config.yml

Fixing the update timeout problem

In my case, the CLI update gave this error:

PHP Fatal error:  Call to a member function fetch_array() on resource in [...]/install/update/new/phpbb/db/migration/data/v32x/fix_user_styles.php on line 42

This is a bug in the migration script. The most easy way to fix it, is to go into your config.php and change the $dbms from mysql to mysqli. This is recommended anyway.

If this is not possible for you, open the mentioned file and search for:

$enabled_styles = $result->fetch_array();

And replace this with:

$enabled_styles = $this->db->sql_fetchrowset($result);

Thanks to RMcGirr83 and Marc on this thread.

Clementine Music Player needs to be started twice, no window on first start

Filed under: Linux — Tags: , , , , , , , , — Christopher Kramer @ 15:01

clementine music player logoIn Ubuntu 18.04, I start Clementine Music Player, but no window is coming up. But once I start Clementine another time, it comes up.

This is not a bug, it is a setting. So this is what you want:

Tools -> Preferences -> Behaviour -> When Clementine starts -> Always show the main window

No, you are not alone, it is you, me, and a bunch of other people.

Debian Unattended Upgrades: Upgrade Third Party mono packages (sury.org, icinga)

Filed under: Linux,Security,Server Administration — Tags: , , , , , , , , , — Christopher Kramer @ 19:36

When using the official third-party repository of mono in Debian, unattended Upgrades will not upgrade the mono packages unless you allow the origin. To do so, edit your /etc/apt/apt.conf.d/50unattended-upgrades , which may look like this:

Unattended-Upgrade::Origins-Pattern {
      "o=Debian,n=${distro_codename}";
      "o=Debian,n=${distro_codename}-updates";
      "o=Debian,n=${distro_codename}-proposed-updates";
      "o=Debian,n=${distro_codename},l=Debian-Security";
};

To also update mono packages on Debian Stretch, add XamarinStretch as Origin:

Unattended-Upgrade::Origins-Pattern {
      "o=Debian,n=${distro_codename}";
      "o=Debian,n=${distro_codename}-updates";
      "o=Debian,n=${distro_codename}-proposed-updates";
      "o=Debian,n=${distro_codename},l=Debian-Security";
      "o=XamarinStretch";
};

If you use another Debian version or Distribution, like Jessie or Ubuntu, search for the file /var/lib/apt/lists/download.mono-project.com_repo_*_InRelease and check the “Origin: ” line and adjust the origin in the config file accordingly.

Repositories with empty Origin like packages.sury.org

If you find that the Origin of the packages in the repository is not given, then you can also tell unattended upgrade to select them based on the given site. For example, this works for the packages from sury.org:

"site=packages.sury.org";

Icinga repository

The packages.icinga.com Repository has the Origin “debian icinga-stretch”, so this is what you need to add to /etc/apt/apt.conf.d/50unattended-upgrades:

"o=debian icinga-${distro_codename}";

Test your changes

To test if it works, you can run unattended updates manually like this (as root or with sudo):

unattended-upgrade -d

iptables: Accept IP address of current ssh client

Filed under: Linux,Security,Server Administration — Tags: , , , , — Christopher Kramer @ 20:39

You have some service, e.g. webmin, that should not be accessible to the public and block access with iptables? And sometimes you connect from a client that is not yet whitelisted in iptables, and always need to look up its IP and add an iptables rule by ssh. Here is a small shell one-liner that makes your life easier:

iptables -I INPUT -p tcp -s `echo $SSH_CLIENT | awk '{ print $1}'` --dport 10000 -j ACCEPT

This just adds an accept rule to iptables that accepts requests from the IP address of the ssh client to port 10000. Of course, you need to adjust the port. You can just paste this in a bash-script, add a bash alias for it or whatever you want to access it fast.

To remove the iptables rule, just replace -I with -D:

iptables -D INPUT -p tcp -s `echo $SSH_CLIENT | awk '{ print $1}'` --dport 10000 -j ACCEPT

You can create one script or shell alias or for each one for easy access.

If this made your day, just leave a comment.
