That's right. I knew I would have to set up the IP beforehand, and that would not be a problem for me. > Also, security is a concern - you'll do this in a private environment, but > giving the user semi-automated tools for such stuff is not exciting. con=port > is not ideal for non-local connection (we listen on *, not on lo, and this > can already be bad but...). The user can break his (her) system as much as he (she) likes. I don't consider it is a problem. As long as the user does not escape UML, con=port can't be modified, and there's no problem. And if he (she) escapes, he (she) can run anything and bind to any port on any IP, so I don't think it is any worse. Moreover, the ability to bind to a specific IP would allow to bind to 127.0.0.1 (or ::1 iv IPv6 is supported) which would be safer than *. > Wouldn't it be simpler to setup port forwarding on the host (either with > iptables or with a forwarding daemon) than to add this code to UML itself? > Optimization is not a concern here, maintainability is. I don't care about optimization here... ;-) Anyway, as far as I (as a user) am concerned, I think it would be easier to attribute a management IP to each guest, and have each guest listen on the same port on its own IP, rather than attribute a port number to each guest + have to remember what host it runs on or have to setup some redirection.
