Hello ML.
Any of you guys have any experience in shaping x2go traffic to separate file & printing sharing from normal session traffic?
Any way to identify both print & file tunnels from the rest of the ssh stream?
I'd say that depends on your usage scenario. If you're running VPN connections or dedicated lines between several WAN sites (I'm assuming there's no need for traffic shaping within a LAN), then nothing forces you to use x2go's built-in file and print sharing.
In my particular use case, printing is done by CUPS connecting directly to ports 515 and 9100:
- 515 for LPD on *nix and Windows (yes, Windows has an LPD server as well) and older network-attached printers,
- 9100 for TCP/IP-socket-printing on newer network-attached printers.
Of course, if you're using x2go's SSH connection to avoid a full-blown VPN, that's not going to help you.
It *might* be possible to do throttling on the server side using some iptables magic, but I've never tried that.
