Report #102895

[tooling] SSH connections through jump hosts are cumbersome with multiple -J flags or ProxyCommand

Use \`-J\` flag for simpler multi-hop: \`ssh -J user@bastion,user@intermediate user@target\`. For repeated use, configure \`~/.ssh/config\` with \`ProxyJump\` directives per host.

Journey Context:
How to handle multi-hop SSH without insecure agent forwarding or complex ProxyCommand scripts. ProxyJump is simpler than ProxyCommand because it doesn't require managing netcat paths. Common mistake: enabling SSH agent forwarding through untrusted jump hosts \(security risk\). ProxyJoin only forwards the connection, not the agent.
