Bandwidth limiting - comp.os.linux.misc

I have a netork made by a router and two pcs connected to it, one via ethernet (running linux gentoo 2.6.11) and the other via wireless (running mac os 9.2). Since the linux box is always connected and the other in't, i'd like to make it "slow down" downloads when the other one (with mac os) accesses the internet. Is this possible?

Is this possible? What kind of downloads? With p2p you can reasonable use tc to shape outgoing to your needs, preventing the system from hogging your whole bandwidth. If those are http/ftp downloads, you could use squid (http://www.squid-cache.org/) and look into it's delay classes feature. -- Michael Heiming (X-PGP-Sig > GPG-Key ID: EDD27B94) mail: echo zvpunry@urvzvat.qr | perl -pe 'y/a-z/n-za-m/' #bofh excuse 39: terrorist activities

Yes it's p2p, but the point is to activate the limitations only when the other computer is active

I can limit the bandwidth on my linux box (which is *not* the router of the network!), but i have to do it *only* when the other (mac) computer accesses the internet. I think that two possible solutions could be: a) tell the router to redirect all the traffic to/from the mac computer to the linux box, then configure the linux box so that the packets to/from the mac are treated with some priority using queing disciplines. b) write something that when executed on the mac computer sends to the linux box a signal, and configure the linux box to throttle down bandwidth upon receipt of that signal. this should be simpler if only i knew anything about coding under mac os :\ any other suggestion?

This is a good option, but you need the Linux box always on to act as a router and bandwidth limiter. The good thing is you can use it as a firewall, proxy, etc. > b) write something that when executed on the mac computer sends to the > linux box a signal, and configure the linux box to throttle down > bandwidth upon receipt of that signal. this should be simpler if only i > knew anything about coding under mac os :\ I've never used a Mac, so I can't help you there, but I think it can be done. If you are using MacOS X there should be a way to know if the machine is connected, and using an expect script from the Linux machine you could check if the connection is up. But as I said I've never used a Mac.

But as I said I've > never used a Mac. Unfortunately it's mac os 9.2 :\ however i could do a ping every n minutes from the linux box to the mac, which would be a lot simpler but less accurate, or as i said write a little program to manually inform the linux box of the mac connection. I'll manage to solve the problem however, thanks for the help :-)
