SSH Problem on FC2

dougwo · 07-03-2004, 09:30 AM

I just installed Fedora Core 2 and when I try to connect to anything else with SSH, the system just hangs. I suspect that it is the new firewall but I cannot figure out how to disable it completely. I stopped iptables but that didn't help. BTW, I also can't ping anything.

Any ideas what to check next?

O, and it's not a DNS lookup problem because I tried with IP addresses as well.

Welcome to LQ.

Is this just affecting ssh?

When you say "hangs" do you mean that the whole system becomes unresponsive?

What happens when you try in verbose mode:
ssh -vvv user@host

If I am root, and I type ssh xx.xx.xx.xx I get the normal response. If I try to use ssh as a user, I get no response. If I am root and I try ssh user@xx.xx.xx.xx I also get no response.

-vvv yeilds Rhosts authentication disabled. We have a problem houston...

Are you trying to use Rhosts auth? If not - what are you trying to use?

Actually, I was confised with sshd config. I usually just leave ssh in default mode. I'm back to thinking it has somethign to do with the firewall. Why would it work as root and not as a user?

this is a classic questions about RH and ssh
the reason why is because u your firewall is blocking all connections into your box
run lokkit ( go to terminal and type in command lokkit) and check enable ssh coming in.

Good luck

Thanks, I'll check it. But I also foudn out I had two numbers switched in an IP address declared in my hosts file. duhh... Seems to work now. Seems I was trying the IP approach from root, but only with hostname from user account. Me bad.

But I also want to know more abotu the fiewwall so I'l llook at lokkit.

Thanks!
