Greetings, So, the typical use of -Ocancel is quite straightforward: > ssh -Oforward -R 12345:127.0.0.1:56789 user@remote > ssh -Ocancel -R 12345:127.0.0.1:56789 user@remote But this is not so good: > ssh -Oforward -R 0:127.0.0.1:56789 user@remote Allocated port 12345 for remote forward to 127.0.0.1:56789 12345 > ssh -Ocancel -R 0:127.0.0.1:56789 user@remote mux_client_forward: forwarding request failed: port not in permitted opens muxclient: master cancel forward request failed > ssh -Ocancel -R 12345:127.0.0.1:56789 user@remote mux_client_forward: forwarding request failed: port not forwarded muxclient: master cancel forward request failed I'm not sure whether this is a "bug" or not, because I really don't understand what the intended behavior is. But I think that at least in the second case, where you know what port is allocated, using -Ocancel should work to cancel the forwarding request. -Sean Patrick Santos _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
