Tips on Getting Started with PuTTy SSH Client on Ubuntu 22.04 or 20.04

General Tips with PuTTY on Ubuntu

  • SSH Key Pairs: Ensure you have the required SSH key pairs before connecting to a remote server. These are essential for secure connections. If you don’t have them already, you can generate them using the command:
ssh-keygen
  • Save Sessions: Save the session once you’ve set up your connection parameters. This will prevent you from re-entering details each time you launch PuTTY.
  • Ping Before Connect: Before initiating an SSH connection, it’s a good practice to ping the target server. Use the following:
ping <server_ip_or_hostname>

Customizations with PuTTY on Ubuntu

  • Change Font and Size: Adjust font size and style by adjusting your PuTTY session readability. Navigate to Window > Appearance and select the desired font and size.
  • Color Schemes: If you’re not a fan of the default colors, you can customize your color scheme. Go to Window > Colours and adjust as desired.
  • Window Behavior: Under Window > Behaviour, you can decide how the window should behave – such as keeping it always on top.
  • Cursor Appearance: Set your cursor to block, underline, or blinking via Window > Appearance.

Other Tips with PuTTY on Ubuntu

  • Log Session: If you need a record of your activities during the session, you can log it. Head to Session > Logging and choose the desired logging method.
  • Port Forwarding: PuTTY allows local and remote port forwarding. This can be especially useful when setting up tunneling. Navigate to Connection > SSH > Tunnels to set this up.
  • Keep Alive: To prevent timeouts set an interval for keep-alive data packets. Go to Connection and set your desired interval for “Seconds between keepalives”.
  • SCP with PuTTY: Although PuTTY primarily functions as an SSH client, you can also use it for secure file transfers with SCP. Use pscp from the command line for this:
pscp local_file.txt user@remote_host:/path/on/remote/host/
  • Key Agent with PuTTY: Use pageant, PuTTY’s SSH authentication agent, to manage your SSH keys and allow password-less logins.

While PuTTY is incredibly versatile and powerful, the key to mastering it lies in practice and exploration. As you get more familiar with its features, you’ll discover ways to streamline your work and enhance your SSH sessions.

PuTTy Terminal Commands Examples on Ubuntu 22.04 or 20.04

PuTTY in a Linux command terminal is a great way to access remote servers and perform various tasks. In this section, we’ll explore some of the most common commands you might use with PuTTY, including the secure copy client (SCP), utilizing SFTP to manage remote server files securely, and generating SSH RSA and DSA keys.

Connect to a remote server:

The basic command to connect to a remote server using PuTTY is:

putty [user@]hostname

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

Example:

putty root@192.168.1.100

Using the username root, this command will connect to the remote server at IP address 192.168.1.100.

Transfer files securely with PuTTY SCP

The secure copy client (SCP) in PuTTY lets you transfer files between your local machine and a remote server. SCP uses SFTP (SSH File Transfer Protocol) to ensure the secure transfer of your data.

The basic command to transfer a file from your local machine to a remote server using SCP is:

scp local_file user@host:remote_file

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

Example:

scp /home/user/file.txt root@192.168.1.100:/root/file.txt

This command will transfer the file /home/user/file.txt from your local machine to the remote server at IP address 192.168.1.100, placing it in the /root directory on the remote server.

puttygen

This will launch the PuTTY Key Generator, where you can generate RSA or DSA keys. Select the type of key you want to generate and follow the on-screen instructions to generate your key.
