I've just enabled crypto - cry key generate rsa (1024) - on my Cisco

1700 router - but when I launch my Putty client in v1 or v2 SSH mode - they all tell me "Server unexpectedly closed network connection". What do I not have enabled?

IOS version c1700-ipbasek9-mz.124-19.bin

Thanks

Mik

New installation, or pre-existing with prior Telnet access?

Have you set login and passwords on the VTYs?

Is SSH a permitted transport on your VTYs?

Do you have an access list restricting source IP or port number?
