That sounds to me like an upgrade was done, and it didn't finish properly, or the disk ran out of space or something along those lines. Can you check "df -h" and do you see any full file-systems?

I think you're right. I did the "df -h" check and all of the file systems have at least 5GB of space left. (Aside from procfs and devfs, of course.) But I popped the live DVD in and found ssh worked fine from there, so I think an update must have failed.

This install is just a few days old, so I'm going to re-install, do an update and see what happens. I'm going to mark this issue as "fixed", if it comes up again after the update, I'll re-open.

Okay, I just performed a fresh install. Immediately tried to ssh to another machine and received the error

"ssh_askpass: exec(/usr/local/bin/ssh-askpass): No such file or directory Host key verification failed."

So, for some reason, it works fine for me when running off the DVD, but not when installed locally. Any suggestions would be welcome.

That is odd. On my fresh install here, I have /usr/local/bin/ssh-askpass, and it seems to work ok. What utility are you using to run SSH which is calling ssh-askpass? Does regular "ssh" from a konsole session work?

Also, if you run "dmesg" are you seeing anything weird, like disk read errors?

I checked and I do have that file, /usr/local/bin/ssh-askpass.
Actually, I rebooted the system this afternoon and, since then, I've been able to ssh and sftp into remote servers without any problems. (I had previously been using plain "ssh" and "sftp" commands and getting the error.)

As suggested, I looked at dmesg and found no errors or anything of concern. It sounds crazy, but I can't find any reason why it wasn't working and I haven't done anything (aside from reboot) which might have fixed it. But, it is working now, so I'm happy.
