DVB-C TV on Raspberry PI with LibreELEC/Kodi

There are plenty of TVs to chose from and nowadays they all know DVB-C so why go through all the trouble of building a TV player with a Raspberry PI?

Well… because it’s fun and because of the freedom of being able to watch your favourite TV channel on any of your devices – even when away.

Automatically restart Webmin/Virtualmin in case of failure

Running out of memory sometimes happens on swap-less VPSes, and it seems Webmin (together with its twin, Virtualmin) are among the first processes to die in out-of-memory cases.

Setting up a little script to check for and restart Webmin if it is no longer running is a pretty simple (workaround) solution – but should never replace the proper procedure of adjusting the settings or upgrading the VPS to avoid running out of memory in the future.

Directory listing failed in FileZilla with ProFTPd on Virtualmin

Everything appears normal in the FTP server’s log:
fr01-srv proftpd[5591]: 192.168.0.1 – USER testuser: Login successful.

However, in Filezilla things are different:
Error: Connection timed out after 20 seconds of inactivity Error: Failed to retrieve directory listing

How to exclude subfolder from password protection with .htaccess

You sometimes need to password protect a folder or an entire account/website from direct access. That’s easily done with the appropriate .htaccess file in the protected folder plus the mandatory .htpasswd file with the correct user and password combination(s).

Fixing Postfix authentication issues on CentOS 6 with Virtualmin

The weirdest errors are those occurring on a freshly installed system where you’d expect for everything to simply work (with the default configs). But such new installs rarely work.

Roudcube successfully connects and sends emails through localhost. At the same time, external clients are unable to send emails through SMTP. The issues is…

Emails not visible on freshly installed CentOS 6 with Virtualmin

Main symptom of a problem is that emails are visible in the Read User Mail utility in Webmin but they do not show up in either webmail (Roundcube/Squirrelmail), Usermin or any email client configured to connect to the server.

After further inspection, it appears the emails get delivered to /var/mail/usermailbox@domain.tld instead of /home/username/homes/usermailbox/Maildir.

Setting up guest wireless access on Tomato

Guest wireless access is handy when you want to separate guest devices (your friends’ phones and laptops) from your own devices connected to the main network.

To get started, you need a router capable of guest wireless (not every router can do this) already set up and running either DD-WRT or Tomato. This tutorial explains how to set up a router running Tomato that is used only as access point (WAN is disabled/unplugged).

Recover from a broken rpmdb and missing rpm/Packages in CentOS

One can never have too many backups. There’s always room for one more backup. Backups are what keep computers running (most of the time)… Except when backups are not set up. At all. Not even a single antiqued copy exists of what broke down…

Let’s imagine that worst case scenario. Let’s imagine…
