i am connected to internet through linux router. I want to prioritize all SSH traffic over other traffic. I tried to do this using: iptables -t mangle -A PREROUTING -i eth0 -p tcp --sport ssh -j TOS --set-tos Minimize-Delay but it was not effective at all. so i tried this: # i think this creates 3 bands (1,2,3) and band 1 has the highets priority # and i think than every normal packet go to band 2 tc qdisc add dev eth1 root handle 1: prio # marked SSH packets with 1 iptables -t mangle -A OUTPUT -i eth1 -p tcp --sport ssh -j MARK --set-mark 1 # all packets with mark 1 goes to band with highest priority tc filter add dev eth1 parent 1: protocol ip prio 1 handle 1 fw classid 1:1 but the ssh connection was not interactive. My bandwidth is 256kbit. Please can someone help me?
