Hey guys. I have OpenSSH installed on a Slackware 12.0 machine. I'm trying to ssh into it from Fedora 9.

I get in, and then at random times it tells me the connection was reset by peer. When I try to log in again after that, it tells me "port 22: connection refused."

I've used netstat -alnp to make sure that the Slackware server is listening on port 22, and it is. sshd doesn't go down.

After this point, I can never log invia ssh again.

However, if I remove ~/.ssh and redo the keys, I can log in again...but only until it resets on me yet again.

/etc/hosts.deny never changes. There is no firewall involved. This is all on a LAN, so port forwarding shouldn't be an issue.

Any ideas?

[EDIT]
The log in /var/log/secure provides no information, either. Simply redoing the key and deleting ~/.ssh on the client is not enough, either. It has to be done on the server, too.

That's a doozy, could be anything.

If it's possible, the next time your server disconnects and refuses connections can you do a :

and also (if you can, since running sshd in verbose mode makes it run single threaded and die after the connection closes)

on the sshd server that's refusing the connects, kill all you sshd's and run

and connect from the original host

Then post both of those outputs to this thread. That might show us something that will ring a bell.

Best wishes,

Mike
