Re: Packet loss whilst using ssh

Yes, though I now know QoS can be set in sshd directly.

Indeed, specifying <<IPQoS lowdelay throughput>> in sshd_config made the problem
immediately disappear. I could induce it 100% of the time by simulating traffic
congestion (e.g. streaming a video in the background whilst ssh was running).

Debian patching alternate defaults into sshd as opposed to changing the default
sshd_config they ship is like wallpapering over mould on a wall. It may solve
the problem in the immediate future, but really concealed a problem festering
elsewhere in my network.

Thank you for the inputs.

Lloyd
