How to change timezone and synchronize time in Debian Linux

To ensure that things are being logged with correct time stamps in your system logs, it is important that your system is configured for your particular timezone and that your system clock is being synchronized to a correct time source. Normally when you set up your Debian Linux system the correct time zone will be choosen. If the time zone is set wrong for some reason it needs to be adjusted.

To check your current time zone issue the command:

# date
Wed Jul 15 11:05:15 UTC 2009

Horde Groupware Webmail alarms.php memory problem

To enable alarms in Horde Groupware Webmail you must add the following to your crontab:

# Horde Alarms
*/5 * * * * /usr/bin/php /var/www/horde/scripts/alarms.php

Depending on your system, the paths above might be different.

You may experience the following error message when the script is run by cron:

Allowed memory size of 8388608 bytes exhausted (tried to allocate 147 bytes)

To resolve this, edit the file /etc/php4/cli/php.ini. Depending on your system it might be located somewere else on your particular system. Change the memory limit to 128 MB by changing the memory_limit parameter:

memory_limit = 128M

The above problem has occured with Horde Groupware Webmail version 1.2.3 but might occur in other versions as well.

Mysterious new mail icon in system tray

A new mail notification that occurs on the system tray looking like this:

Mysterious new mail icon in system tray

Nothing will happen when you hover the mouse over it or clicking on it. It is hard to understand which software this icon belongs to.

The answer is Vodafone Mobile Connect which is a software used to connect with 3G mobile networks as well as WLAN/Wifi networks using built in devices in your computer. It is being shipped with HP Compaq laptop computers for example.

The icon indicates that you have new unread SMS messages in your mobile device. To read the SMS click on the red Vodafone Mobile Connect icon in the system tray. You can see a bit of the red icon in the right edge of the picture above. Then choose “Show” and then “SMS” in the Vodafone Mobile Connect software.
