Network measurement tools

[Kenn Chen]

Any idea to measure the data packets (byte) sending from clients(PC-win98) to server (HP-UX)? Glance and lanadmin are providing insufficient information to me. Please help, thank.

In order to trace all packets sent by node and addressed to node :

1) start trace putting data into 1MB trace file ( /tmp/raw.TRC0, raw.TRC1).
/etc/nettl -tn -pduin -pduout -e all -f /tmp/raw

2) stop trace -> /etc/nettl -tf -e all
3) Format traces into a file like this :

/etc/netfmt -N -n -l -f /tmp/raw.TRC0 > /tmp/file0

/etc/netfmt -N -n -l -f /tmp/raw.TRC1 > /tmp/file1


-n option -> print IP addresses, not hostnames



I hope this helps

Another nice tool is ethereal. Through which you can see every packet (in fairly good presentation format) being sent between any 2 hosts, as well as a summary on the all the traffic.

The software is free and can be retrieved from
