Hello, I have problems setting up HTB. This is my setup : NET 1024/256 ADSL || eth1 Linux Firewall eth0 || LAN 10.a.a.a I want to GUARANTEE for an IP (10.x.y.z) a 800kbit bandwidth for HTTP download. But When 10.x.y.z does no HTTP download, other trafic must get the whole bandwidth, of course. The script I use (see below) is quite the same as presented at (the greeeeat page) : http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm, the only difference is that I use only 2 classes (HTTP trafic vs other) BUT ( :-(( ) When I root@test# wget ftp.fr.debian.org/debian/ls-lR (...) 21% [==========> ] 4,984,704 106.39K/s root@test# It goes at ~110 Ko, as expected when no other trafic is generated. But if I root@test# wget ftp://ftp.fr.debian.org/debian/ls-lR after the beginning of the HTTP download, the latter goes dooown, and if I run a second wget ftp://..., the HTTP download goes UNDER (really under) the 800 kbits...??!! It seems like there's no difference whether the shaping is done or not. Trafic seems to be classified (tc -s -d class show dev eth0 / eth1), but... Actually my goal is more complicated than HTTP downloads (I need to guarantee bandwidth for H323 -> Netmeeting & co, so both down&up-loads), but I'm just testing for now, and if I can't shape such a simple trafic as HTTP download... Could anyone tell me what I did wrong, or didn't understand... Is this only because one can't shape incoming trafic ? Could Ingress solve my pb ? I don't think so, as Ingress seems to limit the WHOLE bandwidth... Is it a "prio" question ? Thanks for your help PSes : - has anyone experienced H323 trafic shaping ?? if so, scripts are welcome !!! - If CBQ can do better, then I'll turn to CBQ, but it's just like chinese for me...
