How to Connect to Your GPU Instance with PuTTY on Windows

Solidus AITECH Compute Marketplace GPU instances are Linux-based virtual machines (VMs) running on virtualized hardware. Each GPU instance acts as an independent server or can be part of a larger cloud-based environment.

PuTTY is a free, open-source SSH and Telnet client for Windows that allows you to securely access remote servers from a local Windows machine.

If PuTTY is not already installed, visit the official PuTTY website and download the Windows installer from the Package files section. After installation is complete, launch the PuTTY application.

We recommend reviewing the official PuTTY documentation to get familiar with the basics of starting a session.

Configure a PuTTY Session

PuTTY’s documentation explains how to initiate a connection. To avoid re-entering the same settings every time, you can save your configuration as a session.

1. In the Host Name field, enter the GPU instance’s IP address, which is available in the management dashboard.
2. Set the Port to 22 and select SSH as the connection type.
3. Ensure the SSH protocol version is set to 2.
4. If you are using SSH keys, browse to and select your private key file.
5. To skip entering your username on each connection, configure an auto-login username.
6. Save the session configuration.

Once saved, you can reuse this session to quickly connect to your GPU instance in the future.
