This is basically how the multiplexing protocol works right now. Take a look at mux.c:mux_client_request_session() - it passes the stdin, stdout and stderr fds to the primary multiplexing process. >From what you describe, you couple probably use this facility with a custom client that spoke the simple (but undocumented) multiplexing protocol to do what you need. -d _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
