My ssh isn't working for some domains (VPN), but Virtualbox can connect

Hi!

As of yesterday I have this perculiar problem. When I try to ssh into my account I have on a linux server where I keep some of my files (I'm using Cisco VPN) ssh claims it can't find the address.

It's worked fine before, and if I connect using putty in Virtualbox on the same machine it works.

The problem applies both to command line ssh and NetBeans (which uses a java client).

I've tried setting SSH not to resolve DNS in the config file but it doesn't help.

I'm using Fedora 14.

Thanks in advance!

Not sure I can help here, but as a check, before and after you start VPN, can you ping/traceroute to the linux server in question?

When you start VPN, do your DNS servers change?

I get unknown host both with and without VPN.

Yes, the DNS changes

Thanks for replying

Sorry still not much help here, but how does VirtualBox work with establishing its connection to the host if DNS is not working? Are you trying to ssh to hostname or IP?
