Secure Shell on Linux System

A few years ago, telnet has used to connect with remote host or PC on another place. This utility or protocol didn't secure yet. Because the message that you sent did't encripted. Right now, linuxer use another protocol, such as SSH (secure shell). But, to connect with cisco router and other devices, peoples still use telnet. Telnet never die.

To use SSH, you must sure, SSH installed on both sides, local and remote computer. On remote computer, you need SSH server. And on local computer, you need SSH Client. To access remote computer with SSH from local computer, follow this syntax :



Code :
$ ssh user_name@ip_address

where user_name replace with your username on remote computer, and ip_address replace with IP Address on remote computer too.

Example :
[msmunir@msmunir1 ~]$ ssh nhc@202.46.3.75
nhc@202.46.3.75's password: *******
Last login: Mon Jan 12 13:51:04 2009 from 202.46.3.71
[nhc@psjumat4 ~]$

To disconnect from remote computer, just write "exit" than Enter.

[nhc@psjumat4 ~]$ exit
logout
Connection to 202.46.3.75 closed.
[msmunir@msmunir1 ~]$
by. msmunir@batan.go.id
