[LARTC] tcng and scheduling ssh

["Michael P. Soulier" <michael_soulier@mitel.com>]

Hey people,

I have the following tcng configuration:

#include "fields.tc"
#include "ports.tc"

dev "eth0" {
    egress {
        // Voice traffic
        class (<$voice>)
            if udp_dport >= 20000 && udp_dport <= 23000;
        // SSH connections
        class (<$interactive>)
            if tcp_dport = PORT_SSH;
        // Everything else
        class (<$other>)
            if 1;

        prio {
            $voice = class { fifo; }
            $interactive = class { fifo; }
            $other = class { fifo; }
        }
    }
}

So, this should be a simple prio queue, with the above udp traffic
classified as voice, and getting the highest priority. Second, should be
ssh traffic, and then everything else.

The problem is that while the packet counts on the second band go up
initially after the ssh connection, the subsequent traffic, obviously
handled by iptables connection tracking, seems to all go to the third
band. Should it not all go to the second, as it's still tcp port 22?

Thanks,
Mike
