	~~==<br/>FAQ ==~~

	~~=== Ethernet does not work ===~~
	~~Check if the line "allow-hotplug eth0" in the file "/etc/network/interfaces" is activated. You can activate the ethernet interface on a running system with the command:~~
	~~:{\| class="wikitable"~~
	~~\|<code>''ifconfig eth0 up''</code>~~
	\|}
	:'''Remark:''' To work with a nfs-rootfilesystem you have to disable the line "allow-hotplug eth0" in the file "/etc/network/interfaces". Maybe the system was prepared for this method for development and nobody did change it back.

	~~=== How to set a Linux environment variable? ===~~
	~~This example shows you how to configure the system to use a proxy-server with a environment variable.~~
	~~:{\| class="wikitable"~~
	~~\|<code>''export http_proxy=http://192.168.xxx.xxx:xxxx</code>~~
	\|}

	~~=== How to schedule jobs to run periodically at certain times or dates? ===~~
	~~You can use the cron daemon and/or anacron. To use anacron you have to copy or link your program or script into one of the the following folders:~~
	~~:{\| class="wikitable"~~
	~~\|<code>/etc/cron.hourly</code>~~
	\|-
	~~\|<code>/etc/cron.daily</code>~~
	\|-
	~~\|<code>/etc/cron.weekly</code>~~
	\|-
	~~\|<code>/etc/cron.monthly</code>~~
	\|}
	~~For further information have a look at the general linux documentation.~~
