I am trying to capture some specific live IP traces with following cmd


"tshark -i bond0 -R'udp.port==9200 || udp.port==9201' -w WSP_traffic.test.trc"

This cmd should capture all traffic which is going to udp port 9200 or 9201 and
save the trace in WSP_traffic.test.trc file. This file should contain only
traffic from or to udp port 9200 and 9201.

Its seems like the cmd is capturing full traces rather than filter traces.


12:53:02 [rkparc10:~]$ tshark -i bond0 -R'udp.port==9200 || udp.port==9201' -w
WSP_traffic.test.trc
Running as user "root" and group "root". This could be dangerous.
Capturing on bond0
5 12:54:15 [rkparc10:~]$ ls -l WSP_traffic.test.trc
-rw-------  1 root root 148064452 Sep 14 12:54 WSP_traffic.test.trc
12:54:27 [rkparc10:~]$


The file size in huge as copare to 5 captured packets. I checked that file too,
all sort of traffic is there(its a full trace).

If I dont save the output in file and see it on monitor only then it work fine,
it shows only filtered traces.

Please have a look and suggest some solution for the same.

Thank
