SSH Passthrough

Quick Reference Need to connect to a private host behind a jump host? Here are a couple of quick approaches:

1. Use the -J (ProxyJump) Option

ssh -J user@jump-host user@internal-host

This passes your SSH session through jump-host to reach internal-host without extra config files. 2. Utilize SSH Agent Forwarding

ssh -A user@jump-host

Now from jump-host:

ssh user@internal-host

With -A, your SSH keys stay local, but are “forwarded” through jump-host to authenticate on internal-host.
