reg: network utilization

[p.balamurugan]

We are using redhat linux enterprise 2.1 and kernal is 2.4. In this how we can check the network utilization and capture the output for 3 mins ones.

rather lame perhaps....but will work!

let i=0
until [ $i -gt 9 ]
do
echo "------------------------------------- $(date)"
let i=$i+1
netstat -i
cat /proc/net/dev
sleep 18
done

Hi

You can look at using tcpdump between your interface.

tcpdump -i eth0 host $localhost host $remote_host

Cheers

Maybe is a good idea to enable snmp and configure mrtg to graph the network utilization. It's a very simple process.

i used ethereal today for this.
you can capture on all or specific interfaces and get the analysis/stats generated in graphic.

There is a cli version too if you don't use gnome... tethereal.
