Connect to Sigma via SSH

- The user ‘sigmacomputing’ is configured to authenticate via public key. Authorize Sigma's public key according to the instructions of your SSH server.
- For most servers the SSH default port is 22, which is also the default port on Sigma. Check the port on your SSH server matches the port on Sigma.

Sigma defaults to port 22, as is common for most servers.
