Bandwidth monitoring

vinhhv · 07-20-2003, 03:04 AM

Hello all,
I'm using Squid for proxy server but in my LAN has many user download file and sometime internet connection is down.
Can i monitor and control bandwidth with Squid? Or in Linux can support it ?
Thank you very much

i have never used it so all i can do is throw it out there.

snmp (Simple Network Monitoring Protocol)

i'd suggest maybe looking for tools online for such a thing if none come with your linux distribution. i have never needed anything of the sort so i cant really offer any suggestions.

I'm also looking for a monitoring system. I'm looking for a console based, so i can ssh to the box and run it.

If anyone knows of one please let us know

Is there a realtime console based or webbased network monitoring system?

i hope there is, please say there is

I use iptraf, its great if you configure it so it resolves the MAC addresses to a name you specify.
You can run it in Lan-station monitor mode to se how much each computer in your LAN is using..

MRTG comes bundled with RedHat and perhaps Slackware too and you can use your browser to monitor bandwidth usage.

SNMP+MRTG+Apache on Server

and

any browser to connect to the MRTG page.

For a slightly more elegant and systematic approach, you could use iptables - built into any recent kernel. This allows you to keep track of bandwidth with a precision of single packets...

Have a look at

http://www.oreilly.com/catalog/linag2/book/index.html

if you're interested, especially Chapter 10 - IP Accounting, although the others are excellent reading material on basic networking as well.

Good luck...

more than monitor, you can manage the traffic with usefull tool named tc (a part of iproute2+tc ).
