hi! I'd like to priorize ssh traffic, but of course I don't like scp to get priorized, too. In the "actual script" of the howto priorization is done with this: | # TOS Minimum Delay (ssh, NOT scp) in 1:10: | tc filter add dev $DEV parent 1:0 protocol ip prio 10 u32 \ | match ip tos 0x10 0xff flowid 1:10 I'm not sure if I got all of it, but it seems to me, that there is no port match - it seems to me that this rule matches all packets with a Minimize-Delay 16 (0x10) TOS value. I watched some packets with tcpdump and it also seems that scp packets all have the Maximize-Throughput 8 (0x08) TOS value, but all "pure ssh" packets have Normal-Service 0 (0x00). It's no problem to match these packets with iptables (just drop me a note if you want to have the iptables syntax). But the question I have is: Are these TOS-values standard for ssh and scp or do all ssh/scp-clients use the values they like? I searched the net, but haven't found anything usefull, yet. best regards Sebastian -- Sebastian 'spax' Pape | A diplomat is someone who can tell you to go mailto: sebastian@p-a-p-e.de | to hell in such a way that you will look gpg: http://p-a-p-e.de/gpg.asc | forward to the trip. --- Do you want to know more? http://www.p-a-p-e.de/ --- _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
