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).

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. Hit Alt-F2 to open the “Run Application” dialog. Type in gconf-editor to run the GNOME Configuration Editor. Navigate to Apps > Update Notifier. Untick the auto_launch checkbox.

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 [...]

In order to show dates as yyyy-mm-dd instead of the default (for US locale) mm/dd/yyyy I use the following script to launch Thunderbird in Ubuntu (tested with Thunderbird 3.0.4 on Lucid): #!/bin/sh export LC_TIME=en_DK.utf8 [ "$LC_ALL" != "$LC_TIME" ] && unset LC_ALL exec thunderbird “$@” This handy tip comes from mozillaZine.

UPDATE: The issue has been fixed in a subsequent Ubuntu system update, so there should be no reason to go through the steps below if your system is up-to-date. After a recent system update in Ubuntu 9.10 (Karmic) I started getting an error message in Thunderbird starting with “Could not initialize the browser’s security component”. [...]

VMware Player experiences mouse capture problems when run under Ubuntu 9.10 Karmic host. Inside the guest window, the mouse pointer works fine in a top-left rectangle of the window (640×480 pixels?) but outside of this area the mouse pointer switches its focus to the host. Add the following line to the file /etc/vmware/bootstrap to fix [...]
