Telnet vs SSH

I'm enlightened!

Till this moment, I
\* was in the idea that both Telnet and SSH were almost similar protocols.
\* never knew Telnet transmitted all information as plain text, including sensitive information like passwords etc.!
\* was unaware that SSH uses a very strong cryptography mechanism to shield the connection from possible hijackers & eavesdroppers.

Though there's a lot of debate going on about the "latency" and the "bandwidth hit" that comes along with using SSH, I guess those would make sense only if we're talking about a 33K or a 56K modem connection. With broadband connections of upto 1 Mbps being available so easily today, these questions of "latency" and "bandwidth hit" just don't arise! Even if it arises, I'm convinced that it's "pros" definitely outweigh its "cons".

It causes me jitters to even think of how faithfully I'd been using Telnet for around 3 years now without realizing the security threats it posed.

I've switched to SSH once for all. Is anyone going to talk to me about Telnet again? Ssssssssssssssh!

Comments:

ssh has compression so over slow links it better than telnet.

Also ssh allows tunneling of X, again compressed, which makes remote X faster and secure.

Also nautilus supports ssh as a remote transport which makes for a very useful option for remote file browsing.

ssh stands for Secure Shell, telnet is only kept around for old network appliances and routers as far as I'm aware. There are plenty of ADSL routers supplied off the shelf with telnet enabled, not to mention all the Windows PC's, permanently connected to the net, with unwitting owners hosting spyware, denial of service attacks and spam. Security is everyone's responsibility. ssh can also be use for secure ftp sftp. There's also telnet-ssl. Cheers, Peter.
