sorry for previous post. I have no idea what was the reason :-(. I am sure it was set to ''plain-text'', but I have changed email anyway... ----------------------------------------------- hi there! For weeks I am trying to set my network in such a way: server (linux) is connected through ppp0 to internet. There is MLDonkey running on that and it is also Internet default gateway for my LAN. I want as fast access to the Internet as there would be no MLDonkey running - I mean: -- I want MLDonkey to be using ONLY IDLE BANDWIDTH -- After reading HTB manual I configured it in this way: --------------------------- tc qdisc add dev imq0 root handle 1: htb default 10 tc class add dev imq0 parent 1: classid 1:1 htb rate 70kbit tc class add dev imq0 parent 1:1 classid 1:10 htb rate 70kbit prio 0 tc class add dev imq0 parent 1:1 classid 1:11 htb rate 10kbit ceil 70kbit prio 2 tc filter add dev imq0 protocol ip parent 1:0 prio 1 u32 \ match ip sport 4662 0xffff flowid 1:11 tc filter add dev imq0 protocol ip parent 1:0 prio 1 u32 \ match ip dport 4662 0xffff flowid 1:11 ip link set imq0 up --------------------------- So I want MLdonkey to be using low-priority class, becouse I want have fast connection when I am browsing WWW or doing anything else. Here you can see output of tc -s -d class show dev imq0 when there is only MLDonkey running: ---------------------------------- http://josh876.republika.pl/class.txt ---------------------------------- Looking at class.txt it seems it should be working very well, but it is not!!! :-((( but traffic is filtering correctly. Here you can see output of netstat -n ---------------------------------- http://josh876.republika.pl/netstat.txt ---------------------------------- It seems to be hard fighting with such an amount of opened connections (4662), but it was not written anywhere that HTB would not be able to handle that... When I am browsing WWW it is almost as slow as there would be no HTB at all. Why is that??? What is wrong? -josh p.s. I set HTB to 70kbit, which is 8,75kB/s. My connection''s maximum speed is about 11,2kB/s. (my tests) I did write that, becouse many of you would say that all this is becouse queues are growing in my modem - which can not be true.
