[Mandrake 9.1] Login problems with OpenSSH

Hello,

I am running a Mandrake 9.1 server with OpenSSH 3.6.1. I can login on the localhost but when I try to login from the internal network or from outside the internet it gives this error:

ssh_identification_exchange: Connection closed by remote host

My log files give this error:

sshd[4823]: refused connect from 193.172.*.* (193.172.*.*)

(I have replaced the last two bits of the IP with astrics so my IP-adress is not fully revealed)

I am running a firewall (shorewall) but it has port 22 open, so I don't think that that is the problem, since the problem remains when I shutdown the firewall. I can't really think of any more info at the moment which is relevant. I hope anybody can help me out with this.

Thanks in advantage.

Hi,

Can you run ssh with debug and post the output.

ssh -vvv 193.172.*.*

Hi,
Can you post your sshd_config file?

Try renaming your ~/.ssh directory to another name (i.e. move it) and see if that makes a difference.

Here is my sshd.conf: (On my server, of course)

Unfortunately that did not made a difference.

Can anybody help me out with this? If not it is all right, but I would definitely would like to have my SSH server running.
