Re: telnet vs ssh on Core equipment , looking for reasons why ?

Hi

Pardon for blowing your bubble but sniffing ssh keyexchange does not do you any good. The symmetric key is exchanged via a channel aready secured. The keys that is used to secure the channel used to exchange the symmetric key are exchanged via DH-based protocol. If you want to spend your time factoring primes for next 500 years to extract the key, you are more than welcome to try. It is crypto-101.

ssh1 keys can be sniffed easily enough with things like ettercap and the like. Last I checked, it couldn't do ssh2, dunno what the status is now.... --Rob
