but it is not complete. Specifically, I am trying to find out what runs
on ports 6010 and 6011 on linux boxes.
x11 6010/tcp # x window system
x11 6010/udp # x window system
x11 6011/tcp # x window system
x11 6011/udp # x window system
A bit busy at the moment, so hopefully this 'quick' explanation
When you enable X11 forwarding with ssh, each session is allocated
a unique display - typically starting at :1 or :10. These
displays correspond to ports 6001 and 6010, respectively.
Just some trivia you may not know about X11 forwarding:
- the X11 traffic is not sent through an encrypted channel
- a remote user can 'spy' on an ssh session under certain
circumstances by reading off those ports (ie. xkey).
