Hi,

I've posted before about using tethereal for some analysis based on tcpdump-files from a network. While playing around with ethereal and tethereal I realised that I don't know what the difference between the two programs are or if there even is one? That was just something I took for granted that there was no difference. 

I've been trying to do something very simple to start with in tethereal and that is to get the average paketsize from a dump and save the results to a file. However what I get is basicly a copy of the dump-file since tethereal prints the packets to the file and not the result of the statisticquery. How would I do to only get the statistics written?

The next step I wanted to go exploring is to get a output of the usage of different ports by the captured packets. I guess just to count the number of times all ports are used and save the results to a file. Is this possible?

Thanks in advance,

Nicklas
