anybody know of some bandwidth throttling software
i want to monitor and restrict inbound/outbound traffic

IWatkins

I looked for the same thing a while back (for testing purposes) and failed to find anything either simple or cheap.

There does seem to be some stuff, but it is mainly firewall related or is hardware.

If you do find a simple solution I would like to hear about it.

I was after something that could slow a PC network connection to emulate various modem speeds (e.g. 56kbit, 64kbit, 128kbit etc).

isnt this classed as QOS?

Denzil_Dog

cant find anything out there

dsmith

it can be done with linux

Find 1 old PC with 2 10/100 cards. put it between the devices you want to throttle like an additional router - (can also be done with routers but fewer people have spare ones)

if you wanna spend loads of bucks try:
http://www.lightspeedsystems.com/

We demoed a package from them that sat on a pc on our network and allowed us to control bandwidth by application/protocol/time of day etc. You can be really nasty then and prevent everyone from surfing at lunchtime. (Unless their IT of course!)

Try http://www.shunra.com/nimbus.htm. Limits from modem speeds up to 256k bandwidth. Main limitation for us is that it won't work on a machine with two network cards, but other than that it's not bad.

cheers Dave
much appreciated mate
have you tried it with 2 nics? what happens?
does it just restrict one of the cards?
if so which one internal(lan) or external?
i will try it and find out myself

thanx again bud, i couldnt find anything like this anywhere on the net

DavidRB

No worries. From memory, I think it won't install on a 2nic machine.

Denzil_Dog,

AFAIK, the QoS stuff on Linux allows you to manage either (or both) NIC's. It will restrict on high level stuff like HTTP, FTP, etc., but it won't determine what services are running over these.

So, say you had requirements for teleworkers to connect to a Thin-Client over HTTP from their web browser. You couldn't say, give them 75% and the rest of the grunts 25% for all their web browsing cr@p. You could however, identify these services using IP addresses or port numbers, but it's a bit messy and cumbersome.

To do 'intelligent' bandwidth management, then you need something like PacketShaper. It's a tad expensive, but that would depend on what budget you have.

Cheers David,

It works a treat on a 1 NIC machine (which I need). Did try it on a 2 NIC machine and just wouldn't install.

Cheers
