Topic: Bandwith Monitors & limitors

[Caos]

Hello People

I was wondering if there is a  monitoring tool out there that can monitor network traffic both internal and external traffic. for example grand total of MB downloaded / uploaded  and then totals for each clients usage (uploads and downloads) and if possible be available to view the stats from the web brower??
I

and also
is there a method or a program out there that can limit the internet download speeds to individual cleints. I have 4 pc's on the network but one user has a habbit of downloading excessively.. how can i limit there download speed without impeading on the other clients?

can anyone point me in the right direction
 
i am not familiar with linux so a good how-to will help me even more


thanks
regards
Caos

First question: If your using your e-smith in gateway mode take a look at ntop. It works nicely. Short howto is on http://members.home.nl/timothee/ntop.html (in dutch if that's a problem check the forum for ntop)

Second question: It should be possible but don't think its been done yet. Check the forum for traffic shaping or use google. If you find something that works let me know I'm very interested to see what you come up with.

regards,

Jan

Hi jan  
thanks for that link and just to let you know there is an english version of that page  at  http://members.home.nl/timothee/ntop_en.html

and ofcourse ill let you know if i come across and simple bandwidth shaping program i know there is such a program becuase my previous ISP Optus@home cable has a 3GB download limit then after that the bandwith speed reduces from 400KB/s or below 28.8 Modem dial up modem speed.

but i will keep you informed

Hi,

  You can do this with Quality of Service (QoS). In e-smith (2.2 kernel based) you should go and use cbq and configure it through cbq.init There was some discussing about this in the forums. Actually I believe somebody already has done it. Even more, we were going to do a "web manager panel" for this but haddnet found the time and we are just awaiting for 5.6 to do it (in our case probably with HTB instead of CBQ as its better and supported in 2.4 kernels ome way).

Hi,

I personally use a little program called IPtraf. You can monitor any interface you want with it. I like it, it does the job well

As for the bandwith limitation, that is possbile using squidguard. You can limit the speed of transfer for any file by its file extension quite easily.

Thanks every one

Sam thanks for the squidguard info what i was really after is a program thats limits the bandwidth after a certain amount that the client has downloaded for example my home isp (optus@home) has no bandwidth limits or throttling till you reach 3gb then it limits the bandwidth speed to 28.8 k dialup modem speed. what i want to set on esmith (5.1.2) is soon as one client reaches an X amount of usage to limit that client only??
 but if its to complex to set this up (im very new to the world of linux) you know of any web sites or simple how-to's on installing and setting up squidguard??

thanks
