I suppose that works, but it'd be better to do this server-side. That way,
the script run on the server doesn't have to trust the client to pass along
correct information. For example, if a client tries forwarding thousands of
ports, the script could reliably detect that and close the connection.
(This is a remote diagnostics script; the remote client is untrusted.)
By the way, it'd be helpful to be able to specify eg. "PermitOpen none"; I
ended up arriving at the same hack that this guy used:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543683. It's minor, but
it'd be nice to be able to do this correctly.
