Changing the port number of SSH daemon is a quick way of reducing the number of SSH brute force attacks your server might face (check the file /var/log/auth.log to see if there are many failed SSH login attempts). Just to be on the safe side, create a backup copy of the SSH daemon config file. […]
Here’s how to disable the annoying Update Manager pop-up (technically a “pop-under”) and instead have the update icon displayed in the notification area.

This post is an update on integrating Thunderbird with Ubuntu’s notification system. For Ubuntu 10.04 Lucid Lynx it supersedes my earlier post on the topic which was applicable previous versions of Ubuntu (Jaunty and Karmic). The big difference in Lucid Lynx is the Indicator Applet and the “Me Menu”, both of these incorporating features related […]

However during the compilation I got errors about virtual network device, even after trying to recompile several times including from command line.

Add the following line to the file /etc/vmware/bootstrap to fix […]

However, those steps were applicable to Ubuntu 9.04 only and have no effect in Ubuntu 9.10 (Karmic Koala). The necessary changes to enable Ctrl-Alt-Backspace to restart X in Karmic are below. Open Preferences > Keyboard and […]
This post is about how to change the resolution (i.e. font size) of virtual terminals or “tty” in Linux. Virtual terminal is the basic command line interface which you see when you press <Ctrl><Alt><F1> (note: to get back to your existing Gnome or KDE session press <Alt><F7>). This is different from the Terminal emulator, such […]
Unfortunately the default memory settings for Eclipse are not sufficient to run BIRT properly on Ubuntu. Editing BIRT reports was fine on my machine, but the preview always crashed or froze Eclipse. When run from the command line, errors like these came up: Exception in thread “SocketListener0-0” java.lang.OutOfMemoryError: PermGen space Exception in thread “SocketListener0-1” java.lang.OutOfMemoryError: […]
