Hello! Sorry for posting this, i know its slightly OT. But i hope to get help here cause most of the networking/sysadmin ppl hang around here! ;) I have read the Howto (Section 9 exspecially!) a few times. It might be the language that i not get this or whatever! I want to make sure that port 14567 (upd) is in a priority 1 band (Minimum Delay). Port 14567 is used by an Online game, a low ping is badly needed. I decided to use Token Bucket Filter ( i hope i have chosen the right one) (...)Note that we use 'tc class add' to CREATE classes within a qdisc, but that we use 'tc qdisc add' to actually add qdiscs to these classes.(...) 1.) Do i have to create a class first ? example: tc qdisc add dev ppp0 root handle 1: htb default 30 2.) then i have to add qdisc to a class? example: tc qdisc add dev ppp0 root tbf rate 220kbit latency 50ms burst 1540 3.) set filter ? example: tc filter add dev eth0 protocol ip parent 10: prio 1 u32 match ip dport 22 0xffff flowid 1:1 I have read the howto but i can not find my mistake! I hope u can help me, i am really new to this! Cheers, Mario
