Hello!
I have an internet connection of 64kbps garanteed
in a channel of 256kbps. On this connection the metropolitan speed is 10Mbps and
in the provider's network the speed is 100Mbps.
I have a few clients behind my linux box and i want
to set up some limitations because some of them are using it
irrational.
I am marking the packets with 0 for internet; 1 for
metropolitan 2 for provider's network.
Afther the mark i send the packets to the followind
classes:
script for eth0 (eth0 is my local
network)

After i start the scripts all the hosts encounters difficulties in
accessing the internet... the web from the internet (class 1:1) are loading
verry slow (20-30 seconds); i have ping timeouts... yahoo messenger is
connecting in about 20-30 seconds... iti si a mess...
I know the bandwidth is verry small but even if there are 8 users online
the bandwidth should divide and work much faster at least for web...
I think the script has problems in the part with the burst of 15k... can
somebody tell me where is going wrong?
Please help,
Claudiu. |
