Hi,

Hi,

You could look into the "dscp" module for iptables, and match on both TCP port and DSCP markings. OpenSSH uses different IPQoS configuration settings for interactive sessions and bulk transfers.

Today I Learned that OpenSSH has IPQoS options to differentiate interactive vs non-interactive connections.

You can check your settings with "ssh -G":

     $ ssh -G ssh.example.com | grep -i ipqos
     ipqos lowdelay throughput

Search the ssh man page for IPQoS for more details.

TL;DR: The first option is interactive and the second option is non-interactive.
