But normal ssh commands should, of course, be in 10: I don't know why it is not working for you, but I've just tried the above commands myself and it works for me, so at least you know that the example is correct. > The system is running within a VM on linux kernel 3.7.10. > I can't figure out what's wrong here. Any help is really appreciated. My test was with Linux 3.0.0, not inside a VM. You could maybe use some iptables logging to see if the packets have the TOS value that you expect? You could also try setting some TOS values with iptables and see if that works.
