Hello everyone,

I'm looking for a bandwidth shaper that can limit downloads from certain IPs on a LAN.

Any suggestions? I'm thinking of something that's easy to set up and configure. Even better if there's already a package that's on the CentOS repositories (or if not, maybe an RPM).

It's non-trivial to set this up on linux but it can be done with the kernel QoS support. Look at www.lartc.org.

actually, i just saw this and it looks interesting:

Please report back to the list with a summary on this if you get it working.

As an alternative, you can use FreeBSD and its DUMMYNET driver, which does this stuff in a more simple-to-understand fashion.

warning: the linux 2.4 kernel simple traffic shaper was abandonware, and did not work for me despite lots of effort.

caveat: I last did any significant research into this stuff about 5 years ago and while i've generally tried to keep up to date there may be new tools i'm not aware of.
