I would like to forward-on-demand a local port to remote one over ssh. Currently as a hack I use a socket unit with accept=yes together with a service template unit that looks like:
[Service] ExecStart=-/usr/bin/ssh options sever nc localhost port StandardInput=socket This works, but rather inefficient. The data is first copied to systemd, that copies them to ssh, that forwards them to the nc command running on the remote host that finally sends the data to the port. It would be much better to use ssh -L port-forwarding option to avoid all those extra data copies. Unfortunately ssh with its -L option does not support inetd-style socket passing and always binds itself. I suppose I can try to patch ssh to support that, but perhaps there is some magic option in systemd that allows to redirect the accept request to a new listening socket that ssh creates with its -L option? _______________________________________________ systemd-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/systemd-devel
