Hi Scott, the server is in the USA, and I'm in ZA. I've been trying to
get the IDC to look into the problem, but they're not very helpful and
recon I need to check my software. I know the "server" runs desktop
hardware, so it could be a hardware problem, but they don't seem to
think so.

So, I'm trying todo everything I can, from my side, via SSH to see if
I can figure it out.
