WinSCP Plink

WinSCP Plink” refers to the integration of PuTTY’s command-line tool with WinSCP, a popular open-source SFTP (SSH File Transfer Protocol) client for Windows. Plink is part of the PuTTY suite, which is a group of networking utilities for securely connecting to remote servers through SSH, Telnet, and other protocols.

When WinSCP cannot use its primary SFTP engine (for example, when connecting to specific servers or settings with special setups), it can use the PuTTY “plink” utility to create a secure SSH connection and perform file transfers or other SFTP activities.

WinSCP Plink: Working

1. Plink is a command-line utility included with PuTTY. It connects to remote servers via SSH, enabling secure shell sessions, remote command execution, and port forwarding. Plink supports a variety of authentication mechanisms, including password-based and public-key authentication.

2. When the built-in SFTP engine is unavailable, it can use Plink as a fallback method. This is typical when the remote server’s SFTP subsystem is not correctly configured or when specific SSH server settings are incompatible with WinSCP’s SFTP implementation.

3. When WinSCP needs to use Plink, it will launch the Plink executable with the necessary parameters, such as the target host address, username, and authentication mechanism (password or secret key). Plink will then connect to the remote server through SSH.

4. Once the SSH connection is established, WinSCP can use the secure channel provided by Plink to perform file transfers, directory synchronization, and remote command execution on the server.

Conclusion

To use WinSCP’s Plink integration, we must have both WinSCP and PuTTY installed on the Windows PC. The article also outlines the working of WinSCP Plink provided by our Tech team.
