The box will provide the following services:
The resulting machine will have quite a small footprint: about 600M, and except if your network is intensively used, a low spec computer can be recycled to do the job. As the machine is going to operate as a router/firewall Fri, 20 Jun 2008 19:14:01 +0200 When copying files over the network, the files informations can be modified. When using cp, one can avoid this issue by using the -a which will do the copy in archive mode, meaning that it will keep the links, preserve mode, ownership and timestamps and the copy is recursive. the solution to this over the network is rsync alongside with ssh.

Sat, 03 May 2008 16:26:15 +0200 This tutorial will go over the steps to go through in order to set up a serial console on Debian Linux. Debian uses sysvinit to handle the booting process, amongst the different task, and as such, there is a few differences between most of the tutorial that you might find on the internet regarding how to set up a serial console.
