One of my Cisco routers died over the weekend, Cisco sent the replacement and I restored the the config using copy tftp: running-config. Everything seems to work fine but I can no longer ssh into the router (I can telnet). The connection is refused, so it isn't listening on port 22 it seems like.

I had previously backed up the config by just doing ssh router 'show run' > backup_config from my workstation.

So:

Is there anything wrong with my method of backup vs copy running-config tftp:?
I know I haven't given any debug information, but is there something typical I need to do to get ssh working?
