The Roundcube version (0.3.1) in Debian Squeeze is just too outdated. To create a new Debian package, using the latest version of Roundcube, is fairly easy. Download the latest source (currently 0.8.1) from http://www.roundcube.net/download, and put the TAR image (roundcubemail-0.8.1.tar.gz) in /usr/src. Now execute at the command line $ cd /usr/src $ apt-get install devscripts […]
One way to secure your MySQL backups, is to encrypt the backup file using PGP/GnuPG. Of course you will need to own a PGP/GnuPG private key, which can be easily created using the PGP/GnuPG tools. On a Debian/Ubuntu Linux host, install the ‘gnupg’ package. # apt-get install gnupg After installation, generate a PGP/GnuPG key using […]
It can happen that a VMWare virtual machine (VM) runs out of space after a certain amount of time. If the installed Debian Linux (actually any kind of Linux) has been set up with LVM, resizing the partition is fairly easy. This article assumes that the VM has been installed with just one root partition, […]
When you are not using Debian unstable or some kind of Linux distro that hasn’t got the latest version of the dmesg command, you will not be able to execute ‘dmesg -T‘ to see human readable timestamp in the output. A small Perl script does the trick: #!/usr/bin/perl -wn use strict; foreach my $line () […]

Recently I have been asked to write a Syslog event generator, but not just a normal syslog generator, it had to be able to generate events coming from different hosts. The normal ‘logger’ command sends Syslog messages using the machine’s IP address, so logger wasn’t very useful. The only thing useful seem to be, to […]
Introduction OpenVPN is an opensource Virtual Private Networking (VPN) solution which can be downloaded freely on the Internet. It also included in almost every Linux distro to-date, so it can be easily installed using your distro’s favourite package manager tools. It uses the SSL/TLS VPN stacks, which makes it different from almost every other VPN […]
On Debian based distributions, a handy tool called dh-make-perl can be installed to ease the installation of CPAN Perl modules on the system. This tool will create a Debian package of the CPAN module, and can also install this package automatically. The advantage of this procedure is that when the CPAN module is picked by […]
This Perl script was initially written about 3 or 4 years ago, but still does its daily job: monitor that certain processes are running and if not, restart them (plus send out a notification). The script should run as the root user (since it will be restarting services or processes), and can easily be configured […]
