User id for the forwarder ports
Hi,
Question:
Can a TCP server (running on the same host as the OpenSSH server) know
the user id/name of a user forwarding an TCP port ?
I.e. if someone on some client machine does
ssh -L9999:localhost:9999 someuser at somehost
nc localhost 9999
and a service accepts the connection on port localhost:9999 on
somehost, can it somehow safely read out the user name "someuser"?
Long explanation:
We consider using SSH port forwarding as a way to enforce
authentication and author...
