Hi Stef, lo all, Am hoping someone could have the time to look at my simple script, it basically tries to restrict users based on their ip, but I also incorporated the hints given by Stef on being able to allow local traffic unrestricted. no iptable marking (fw filter) is used, just tc. I see traffic passing thru all the classes when ever those systems are in use. Ave done some stress test on the local traffic by plugging p2p/web crawlers on the LAN of one of the systems, each time i notice that the parent ceil limit is being broken. I have met the one major requirement, sum of child classes rate <= parent rate. I dont know what else i might be doing wrong, once placed perturb to 1, and internally(kernel) am using PSCHED_CPU and a sfq buffer length of 15 as against 128. (notes on docum.org) to try and increase speed. (Processor has TSC flag) Would be much obliged on any comments/improvements i can make on the script. Using kernel 2.4.22 TIA K _________________________________________________________________ MSN Shopping upgraded for the holidays! Snappier product search... http://shopping.msn.com

It''s better to add 1 class to the root qdisc and attach all other classes to that class.

Thanks Stef,
but then, what bandwidth should I place on the first class, 10mbit or
90Kbit?
am re-writing the script to follow what you''ve just suggested, it will
look
like this...
root (1:0)
|
class (1:2)
(10mbit or 90Kbit or nothing ?)
/
\
class (1:3)
class (1:4)
(LAN Traffic) (10Mbit) (90Kbit)
(Internet Traffic)

1:10
1:11 - 1:31 1:50
(high prio icmp,ack)
(sys01 ... sys20) (default)
1. Is this what you''re asking?
2. Is there any other improvements I can make on the script to make it
efficient?
Thanks
K
