I have a hobby server running Ubuntu 7.1. I can use SSH to connect to it just fine from my powerbook, but i cannot connect from my powermac. I type ssh dave@192.168.1.254 in terminal, and the system just sits there for about 30 seconds, then returns this:
Wrie failed: Broken pipe
Any ideas why i can connect from one machine but not another? Any log files from either machine that i should be looking at?

Can you ping that IP from your Power Mac?

Also, try ssh -v dave@192.168.1.254 (-v is for verbose mode) to get some more details about the connection attempt and failure. Share the results in a [code][/code] block.

Hmmm... it seems there are other Ubuntu users with similar issues out there. Try this idea: on the server, edit your /etc/ssh/ssh_config file to set GSSAPIAuthentication to "no" instead of "yes". Then restart sshd and try connecting again.

Im just a little confused as to why one machine can connect to it while another cannot.

I'll go edit the file, but how do i restart sshd?

You're running a Linux server and you don't know how to restart the daemons?

It varies by distro, but this probably works:
Code:
sudo /etc/init.d/sshd restart

still no go after the reboot. i think that the sshd is working just fine since i have never had a problem connecting with my powerbook, so wouldnt the problem be with my pmac and not the server?
