Pointers on Getting Started with PuTTy SSH Client on Ubuntu 22.04

General Pointers with PuTTY on Ubuntu

• SSH Key Pairs: Before logging in to a remote server, make sure you have the necessary SSH key pairs. These are necessary for connections to be secure. The following command can be used to generate them if you do not already have them:

ssh-keygen

• Save Sessions: After configuring your connection parameters, save the session. By doing this, you won't have to enter your information again every time PuTTY launches.
• Ping Before Connect: Pinging the destination server is a recommended practice prior to establishing an SSH connection. Make use of these:

ping <server_ip_or_hostname>

Customizations with PuTTY on Ubuntu

• Change Font and Size: To change the readability of your PuTTY session, change the font size and style. Go to Window > Appearance, then choose the font and size you want.
• Color Schemes: You can change the color scheme if you don't like the default selections. Select Window > Colours and make the necessary changes.
• Window Behavior: You can set the behavior of the window, such as keeping it always on top, under Window > Behaviour.

Other Pointers with PuTTY on Ubuntu

• Log Session: You can log the session if you need a record of what you did. Navigate to Session > Logging and select your preferred logging technique.
• Port Forwarding: Local and remote port forwarding is supported by PuTTY. This is particularly helpful when tunneling is being set up. To configure this, go to Connection > SSH > Tunnels.
• Keep Alive: Establish a keep-alive data packet interval to avoid timeouts. Select the "Seconds between keepalives" interval that you would like. Go to Connection.
• SCP with PuTTY: PuTTY is primarily an SSH client, but it can also be used with SCP to perform secure file transfers. For this, use the command line utility pscp:

pscp local_file.txt user@remote_host:/path/on/remote/host/

• Key Agent with PuTTY: PuTTY's SSH authentication agent, pageant, can be used to manage your SSH keys and enable password-free login.

PuTTY is very strong and versatile, but learning how to use it effectively requires experimentation and practice. You'll find ways to improve your SSH sessions and expedite your work as you become more acquainted with its features.

PuTTy Terminal Commands Examples on Ubuntu 22.04

A Linux command terminal with PuTTY is an excellent tool for accessing remote servers and carrying out different operations. We'll go over some of the most popular PuTTY commands in this section, such as creating SSH RSA and DSA keys, managing files on remote servers securely with SFTP, and using the secure copy client (SCP).

Connect to a remote server:

The following is the basic PuTTY command to connect to a remote server:

putty [user@]hostname

Where hostname is the hostname, or IP address, of the remote server, and [user@] is the username you wish to use to connect to it.

Example:

putty [email protected]

This command will establish a connection to the remote server at IP address 192.168.1.100 using the username root.

Transfer files securely with PuTTY SCP

Using PuTTY's secure copy client (SCP), you can move files from your local computer to a remote server. To guarantee the safe transfer of your data, SCP makes use of SFTP (SSH File Transfer Protocol).

The fundamental command to use SCP to move a file from your local computer to a remote server is:

scp local_file user@host:remote_file

Where user@host is the hostname and username of the remote server, remote_file is the path to the file on the remote server, and local_file is the path to the file on your local computer.

Example:

scp /home/user/file.txt [email protected]:/root/file.txt

Using this command, the file /home/user/file.txt will be moved from your local computer to the remote server located at IP address 192.168.1.100. It will then be stored in the remote server's /root directory.

puttygen

This will start the PuTTY Key Generator, allowing you to create keys using either DSA or RSA. To generate your key, choose the kind of key you want to create and adhere to the on-screen directions.
