Putty

Getting Started with Putty

PuTTY is a free and open-source terminal emulator, serial console, and network file transfer application. It is widely used for establishing secure SSH, Telnet, and SFTP connections to remote servers.

When you first launch Putty, you will be greeted with the main configuration window. Here, you can specify the connection details, such as the host name and port number for SSH access. Once you've entered the details, simply click "Open" to initiate the connection.

Putty is straightforward to use and perfect for connecting to remote servers via SSH or Telnet. It’s an essential tool for network administrators and anyone who works with remote systems.

Configuring Putty Sessions

Putty allows you to save your session settings for future use. This means you don't have to re-enter connection details every time. To save a session, just enter your details and click "Save". You can then select your saved session and click "Load" whenever you want to connect to the server.

This feature is particularly useful for those who need to regularly connect to multiple servers.

SSH Key Authentication

Putty supports secure key-based authentication for SSH connections. This method is more secure than using passwords alone, and it’s highly recommended for any sensitive server connection. To set up SSH keys, use PuTTYgen to generate a public/private key pair.

Once your keys are generated, you can add the public key to your server’s authorized keys and configure Putty to use the private key for authentication. This ensures that your connection is both secure and convenient.

Putty Terminal Settings

Putty provides a wide range of customization options for the terminal interface. You can change font size, colors, and background images to personalize your terminal session. There are also advanced options for controlling the appearance of the text and cursor.

• Font Settings: Adjust the size, style, and family of the text displayed in the terminal.
• Window Colors: Customize the background, foreground, and ANSI color settings.
• Cursor Appearance: Choose from different cursor shapes and behaviors.

Logging and Session Recording

Putty allows you to log your sessions, which can be useful for troubleshooting and keeping a record of your actions during a connection. You can enable session logging in the configuration options, and specify where the log files will be saved.

Additionally, you can set Putty to log the entire session, including the text displayed in the terminal, which can be helpful for auditing or documentation purposes.

Advanced Features: Proxy Support

Putty includes built-in support for connecting through proxies, allowing you to bypass restrictions or access servers in regions where direct access is blocked. You can configure Putty to use a proxy server for SSH connections, including SOCKS and HTTP proxies.

This feature is useful for network administrators and users who need to access servers through a secure tunnel or hidden network.

Putty for Windows and Mac

Putty is available for both Windows and Mac. While the Windows version is widely used, Mac users can also enjoy a version of Putty, often through a package manager like Homebrew or MacPorts.

Putty for Mac works similarly to the Windows version, offering the same features and configuration options for SSH connections.

Why You Should Use Putty

In summary, Putty is a lightweight, free, and powerful tool for securely connecting to remote systems. It helps:

• Enable secure SSH connections for remote administration.
• Customize terminal appearance for better usability.
• Save session configurations to quickly reconnect to frequently used servers.
