There was a problem hiding this comment.
Should this also call forwardSSH(ctx, sshConfig, port, localUnix, remote, true) to tear down the unused forward?

On macOS, listening on 127.0.0.1:80 requires root while 0.0.0.0:80 does not require root. For such ports, the hostagent launches "pseudoloopback" forwarder that listens on 0.0.0.0:80 but rejects connections from non-loopback src IP. Signed-off-by: Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp>
