Feature request: virtual servers

[Philipp Marek]

Hello everybody,

I'd like to get SSH provide some virtual server feature.


Eg. when connecting to an existing server on a different port I'd like to 
chroot all users to some directory.


This can currently be done by starting sshd twice, with different config 
files (or perhaps command line options); but getting that "right" for all 
circumstances (init.d, upstart, systemd, ...) is hard.

So I'd like to ask for the "Match" statements to allow matching the 
accepting port number and/or IP address.


Another example: when connecting to a service-IP-address I want to use some 
"common" host keys, not the per-server generated ones; but, as the files 
might only get accessible when the service IP is on this machine, too, that 
would mean loading the server keys _after_ accepting the connection ... so 
that might be a bit more work, but would be much appreciated!


Regards,

Phil
