Hello and welcome to Networking Mafia, in this blogs we are going to explain what is SSH and how to configure in Cisco devices, basically SSH is like a Telnet but SSH is a very secure protocol because it shares and sends the information in encrypted form. Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another.

SSH using by default 22 port number but it can be change easily.
SH is more secure so it uses public key encryption for authentication.
SSH suitable for Public networks because it is very secure.

1 Steps

Router>en
Router#configure t
Router(config)#interface gigabitEthernet 0/0
Router(config-if)#ip address 10.0.0.1 255.0.0.0
Router(config-if)#no shutdown

2 Steps

We have successfully configure basic configuration now we have to configure Hostname or Domain Name in same Router.

Router(config)#Hostname R1
R1(config)#ip domain-name www.networkingmafiablogspot.com

Note:-Hostname is your Router Name and domain Name you can give anything as per your requirement.

3 Steps

Now we have to configure vty connection in the same Router or SSH command.

R1(config)#Line vty ?
<0-15> First Line number
R1(config)#Line vty 0 4
R1(config-line)#login local
R1(config-line)#transport input ssh
R1(config-line)#exit

Note:-Total vty connection available on this router 16, vty means how many devices can access this particully router at a single time on remotely, you can allow all 16 connection it is depend on your requirement.
