Unsetting parameters for specific hosts in SSH config

Question

In .ssh/config, I have set a RemoteForward for all hosts in a given domain:

Host *.[domain]
   RemoteForward [remote-port] 127.0.0.1:[local-port]

How do I unset that parameter for a specific host within that domain (e.g., git.[domain])?

The ssh_config manpage mentions the use of negation to exclude certain hosts, but only for keys in the .ssh/authorized_keys. Have tried similar combinations in .ssh/config but no dice — Gingi

From the manpage I'd expect Host !git.[domain],*.[domain] to do what you want. What are the combinations you tried? — dave4420

Try the ClearAllForwardings setting:

Host *.[domain]
   RemoteForward [remote-port] 127.0.0.1:[local-port]

Host git.[domain]
   ClearAllForwardings yes

Does git not automatically set ClearAllForwardings=yes, as scp and sftp do?

It does not seem to. I had set RemoteForward 52698 127.0.0.1:52698 on top of ~/.ssh/config to use rsub on all domains, but then started getting Warning: remote port forwarding failed for listen port 52698 when connecting to GitHub (since it obviously doesn't allow forwarding a port). With ClearAllForwardings=yes under Host github.com the error went away.
