It's an important design goal to keep the sshd process small and simple. So no, there's no interface to dynamically add code, and I doubt there will ever be one. Just create your own program on the server that does what you want and start it from a remote system either with "ssh server yourprogram" or alternatively you can configure the program to be a subsystem[1], in which case you start it using "ssh -s server yourprogram". See "Subsystem" in the sshd man page. //Peter _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
