Port efficiency on pwn-qemu #132
Description
Currently, we have to expose like a chill ~10000 ports in order to run the pwn-qemu challenge. On each instance spawn we spawn a qemu instance and expose the port 22 to one of the PUBPORTSTART - PUBPORTEND ports. The problem however is, that we have to expose all of them, s.t. the users can access them.
It might be more efficient having an SSH Proxy forwarding the user's connection to the designated SSH connection.
Either we write our own proxy. @ecomaikgolf suggested a library, which one was it again?
Otherwise we can use this:
However this probably limits the use of scp, but I haven't tried it yet.
