Hey all, I had asked a question a little while ago about CPU usage being outrageous while using tc and a cbq qdisc. Ed was very kind and offered a few suggestions. One of these was to look at hashing. So after pounding away at it for about a week, I have a general understanding of how it works and have tried to implement it. Unfortunately, and quite obviously since I''m posting here, it

Hey there everyone, I appreciated everyone''s help so much in the last few posts I decided to post some more! :) We implemented our bandwidth management machine on the network last week and everything looked great. After looking at it today, anything past the machine is losing major packets and the latency is high. I''m using RedHat 9.0 on a Pentium 4 2.8ghz with 512mb of ram.

Hey all, I wanted to let you all know the hex thing worked out for me. Thanks again. I had another question though that was sparked by Ionut Gogu''s question on monitoring. I setup and installed ntop for this purpose and noticed that we have so much traffic it is killing the machine. We have 1 GB of ram in there and it is not enough. It still overflows to the swap file and eats about

Here''s the script. I would have posted it to a website, but I figure this''ll be better so it is always on the list for people in the future in case they wanted to see it. If you have any questions about any of it, please let me know. Mike and I aren''t the cleanest of programmers. Cron the script to run whenever you need it to. :) #!/usr/bin/perl # # TC Helper Script:

My problem is I''m guessing the $variable is not allowed to be anything

Hey all, I recently read on a prior post as well as the FAQ that packets can be limited by mac address using the u32 filter. I attempted this and, while all the commands went through with no errors, it is not limiting at all. I''m attempting to limit all IP traffic to a specific destination mac address (00:12:3f:05:43:7f). Here is a quick rundown of the commands
