Linux.com forums seem to be running Ninjaboard (see the source). I found this link which seems to confirm the issue.

Get familiar with the server. What is its primary functions and what applications does it run.

Then run these applications up on your own system, learn them. Play with them and break them. Just do it on your test box not the production box.

Google is your friend.

As long as the system is currently stable and in good shape, any problems will be likely to due to changes YOU make on the system. So be careful and ready to back out of your changes if required.

OpenVPN is a top solution.

I have a guide up on my site for those wishing to install on Ubuntu Jaunty.

Keep it simple.

Use winscp and a batch file called by the windows scheduler to automate a push from the Windows2003 server. Obviously will need to setup keys as well so that login is successful.

Watch it though - I would be ok with signature updates being automated but would prefer to do patching of the IPS manually, you do not want it to break in the middle of the night.
