Hello, Steve and Alex.

I agree with Steve that you would be better to use LTS versions on a 
server. I'm still running 6.06 LTS on some of our servers, but I will 
upgrade these to 8.04 LTS before 10.04 LTS. We mainly run 8.04 LTS.

Re: Your 'crashes' - Your server may be ping'able in single-user, when 
the web server and SSH daemons are not running. Have you checked the 
uptime and tried running "last reboot"?

If your server reboots itself, because of a power failure or some other 
problem, it may end up in single-user mode if filesystem corruption has 
occurred that requires manual intervention to fix. In this state, the 
server may be ping'able, but the web server and SSH daemons won't be 
running.

Bye,

   Tony.
