And how is the memory and cpu usage ?Right now (night) the traffic shaping box is not loaded at all 10% cpu usage and 200MB ram used. Tho at the daytime cpu usage goes up to 70% or so. and ~ 500MB ram. Yes there are errors. Dec 10 22:59:28 p1 kernel: NET: 26 messages suppressed. Dec 10 22:59:28 p1 kernel: HTB: bad diff in events, cl=10243 diff=19E26000 now=434192384 then=4294893568 j=1101578 ... Like this. Just before i left work, i left a file d/ling, to test what happens. Right now i cant reach outside world from that computer (128MB with speed of 128kbit/s have downloaded and it has halted). I can reach the computer from the computer where the traffic shaping is being done. But not from a computer which is a hop from traffic shaping computer internet - router1 - traffic_shaping - ... - me 80.81.33.1 is the router1 at the ISP providing us 8mbit like. It cant be reached from the box which was being shaped. me@myplace$ ping 80.81.33.1 PING 80.81.33.1 (80.81.33.1): 56 octets data --- 80.81.33.1 ping statistics --- 3 packets transmitted, 0 packets received, 100% packet loss Tho it can be reached from box next to me. (my other workstation) me@myotherpc$ ping 80.81.33.1 PING 80.81.33.1 (80.81.33.1): 56 octets data 64 octets from 80.81.33.1: icmp_seq=0 ttl=252 time=62.6 ms 64 octets from 80.81.33.1: icmp_seq=1 ttl=252 time=20.8 ms --- 80.81.33.1 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 20.8/41.7/62.6 ms So there is a problem in the traffic shaping box. Traceroute also stops at the traffic shaping box. Huge problem. Ok, just a second ago i did ''/sbin/tc qdisc del dev eth2 root'' And added the classes again. me@myplace$ ping 80.81.33.1 PING 80.81.33.1 (80.81.33.1): 56 octets data 64 octets from 80.81.33.1: icmp_seq=0 ttl=252 time=24.6 ms 64 octets from 80.81.33.1: icmp_seq=1 ttl=252 time=21.9 ms --- 80.81.33.1 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 21.9/23.2/24.6 ms I can reach ISP''s gateway very smoothly now! Any idee?

The machine is also similar. I had the same problem half a year ago. Anyway, can you tell us what is the version of htb? It''s htb2, isn''t it? Try upgrading to htb3, this will solve your problem. If not, just put a crontab job to restart (i.e. delete and the recreate) the htb classes every 1/2 hour. Hth, Nickola

Will see what the clients gonna do tomorro. Btw, how do you solve this problem? I am about to test it more with 2.4.20 (HTB included) on Sunday P.Krumins ____________________________________________________________ Reģistrē un lieto savu Apollo e-pastu www.e-apollo.lv www.apollo.lv _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

I''m really sorry that I didn''t test and debug this when it was happening, but this is a production machine and I had to find a solution fast. But now I''m rid of it (after upgrading to htb3 in may). [cut]> > delete and the recreate) > > the htb classes every 1/2 hour. > > Yes, i just did it.

I just upgraded, that''s all. Nickola
