I'll take a SWAG at it. Three possibilities I've experienced. 1) Is sshd actually running? (Don't laugh, I had this exact same problem when I first installed FreeBSD. It disappeared after I rebooted once. For some reason, the daemon did not start after install.) If it's not showing up when you ps ax, then it's not running. 2) Your host.domain.name has changed, and the other machines can't make the connection because the host name you're trying to connect to doesn't resolve properly. Can you connect if you try to connect by IP address instead of by host name? (I run into this every time I re-do my windows machine) 3) I experienced a similar issue, the last time I updated the SSH server software on my linux machines. I needed to use a different SSH server type in my client software before I could connect to the servers. Available choices were DataFellows, SSH Communications, and Standard. The version of SSH produced by www.ssh.com had been changed to require standard. Try updating the version of SSH on your other machines maybe. (Really shouldn't need to, but it's worth a try anyway) Tim Tim DeBoer http://www.snarfy.com It is by caffeine alone I set my mind in motion.
