Today we will have a look at SSH, primarily on Linux. This tutorial will show you how to ssh to a server called Server1 (ip address 192.168.1.2) from a PC called PC1 (ip address 192.168.1.3) both on the same network and both running Linux Mint 10.
Most modern Linux distributions come with ssh installed by default but if not you will need the following packages:
ssh (so you can ssh clients from your machine)
openssh-server (allowing remote access to your machine).
You will need to install openssh-server on Server1 and ssh on PC1. Before we can connect to Server1 open up port 22 on any firewalls between PC1 and Server1 (including any routers).
Once installed open up a terminal on PC1 and type:
ssh (username)@192.168.1.2 or alternatively ssh (username)@Server1
replacing (username) with a valid user on Server1. You will be asked for a password so when prompted enter the users password. Once done you will be connected to Server1. It is that easy!!
So that is internal on the same network how do we do it over the internet? You will need to find out the address of your router and then port forward to your Servers internal ip address. For example to ssh to Server1 over the internet you would type the following:
ssh user@routers_ip_address
replacing user with a valid user on Server1. If you have opened port 22 on the router and forwarded any ssh traffic to Server1 at ip 192.168.1.2 then you would be connected to Server1.

Remarkable knowledge! I have been looking for anything like this for a time finally. Regards!
Telnet sends all information in clear text which means anyone snooping around can catch the data and read it. SSH sends the data in encrypted format so even if someone gets hold of the data they can’t read it.
I am a newbee so please have patience with my question. Why use this over telnet?
Thanks
