Hi,
I am wondering how I can use tethereal
to do the following:
I want to write a program that will run continuously in the
background on a VoIP server and display VoIP analysis information on a per call
basis. I would like it to be real-time. I want it to filter out RTP/RTCP
packets so I can retrieve the jitter, packet loss, delay info etc. I know about
using the “Decode as” etc functionality of ethereal. My problem is
that I don’t know if its possible to see this in real time i.e. without having
a person there all the time to stop the capture, save the file etc etc. …Does anyone have suggestions about this?
Slightly off the point, I looked at using tcpdump (linux) to do this but I
would need to know the src IP address/port and the
destination IP address/port. I would rather that all RTP/RTCP streams be
monitored.
Any help appreciated,
Aisling.
