Can't log in to router using SSH v1 since domain name change
 

I had to change the domain name on my Cisco router, and since then my Slackware 11.0 PC cannot ssh in. I shut off / restarted the SSH server on the router (which re-generated a new rsa key required to log in), but I don't know how to get my Slackware PC client to delete the former key and create a new one so it can ssh in.

Any ideas?

Keys are generally held in $HOME/.ssh/known_hosts. You can delete the old key from there to prevent the error.

Thanks for the quick reply!
 

How would I clear that out? Would I do:

root# rm /etc/ssh/known_hosts ?

open it using vi or other text editor and remove the line which contain the host (it's actually one host per line)

rming the file would just remove ALL known host keys. As willysr said, just remove the one relevant line.
