What is PuTTY? A free Telnet and SSH terminal software for Windows and Unix platforms that enables users to remotely access computers over the Internet. PuTTY was written by Simon Tatham. You can download PuTTY from here.
What is SSH? stand for “Secure Shell”. 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. It provides strong authentication and secure communications over insecure channels. It is a replacement for rlogin, rsh, rcp, and rdist.
SSH protects a network from attacks such as IP spoofing, IP source routing, and DNS spoofing. An attacker who has managed to take over a network can only force ssh to disconnect. He or she cannot play back the traffic or hijack the connection when encryption is enabled.
This article will show you how to use PuTTY to SSH to your server:
Launch your downloaded PuTTY application.
- Now Fill Your IP Address you obtained from your host provider in the Host Name / IP Address Field.
- Leave the port field as it is (port 22 – default) unless your provider changed it to another port but they should tell you.
- Make sure the “SSH” option is checked.
- If you want to save the session, so you won’t need to fill the setting again every time you used PuTTY, then fill the Saved Sessions field and then hit save.
- That’s it now click open to open your connection.
- If it is your first time using PuTTY to SSH connect to your server, you may notice an alert like this one. Simply hit Yes button.
After you hit open, PuTTY will bring you to login to your server via SSH connection. In this case you may enter login as root and the root password provided by your host provider.
That’s all you need to know about PuTTY the next step would be getting familiar with the terminal. Next time I will post a snippet lists for most used command when using the terminal console.
