On Mon 13 Jan, savanna bloviated thus: I'm in an interesting situation - I actually want to slow down my network connection, as our users are sucking down too much stuff. Any ideas or pointers or tools to look for? The response is good. In particular, check out the Hierarchical Token Bucket (HTB) queuing discipline (qdisc) which is easy to understand and does a good job of it. It's also in the latest stable kernel, 2.4.20. -- Rev Simon Rumble [EMAIL PROTECTED] www.rumble.net Send email with subject send key pub for public key.

Re: [SLUG] *limiting* bandwidth?
Hi Savanna Very easy to do under linux. Grab the latest version of cbq.init from ftp.equinox.gu.net/pub/linux/cbq/ and also a copy of the linux advanced routing howto from LDP so you understand what the script does. Read the script as it contains all setup doco (or did at v0.6.2) Provides excellent control of per workstation BW on a LAN with a big internet pipe. Started to use it when we had some filesharing apps cause us problems. Should see what a fast PC with bearshare installed (or whatever its called) can do to your internet feed! The script also supports different rates ect due to time of day (but I havent played with that). An example config for one of our workstations is:- DEVICE=eth1,10Mbit,1Mbit RATE=96Kbit WEIGHT=6Kbit PRIO=5 RULE=,1.2.3.4 This limits the BW out of the router to IP 1.2.3.4 on the lan attached to eth1 from any source IP:Port to 96K total. You can also set limits based on source IP and src:port dest:port if you need to. An old P90 with ISA NICs was easily able to cope with 10 PC's.

Any ideas or pointers or tools to look for? The situation is that I've got a Debian server connected to an ADSL connection, with a whole lot of workstations in a 'kiosk' situation - ie no logons. So whilst I could make my Squid server transparent, require passwords, and have some sort of quota system, this wouldn't be good as I don't want passwords. What I'd like to do is limit each workstation connection speed to say modem speed, but not have that affect other users. And of course do it via open source, not using Cisco, etc. Ideas, anyone? www.lartc.org Anand -- `` We are shaped by our thoughts, we become what we think.
