Hi all

i am new to this group.
i have pcap trace files containing netflow data. i want to extract src
ip & dst ip address columns from the pcap files & store the extracted
data in .mat format.
The .mat format is the format which MATLAB reads.
the whole idea is to extract src ip & dest ip addreses , then try some
compression algorithms to compress these data. For trying compression
algorithms, i need to work in MATLAB, that's why the need to extract
the required data from pcap files & store them in .mat (MATLAB)
format.

Hope someone has a solution for this

Thanks in advance,

Amogh Rajanna

Yah, don't do it that way. Extract the src and destination IP addresses
as text, and read that text file in Matlab.

Trying to create a .mat file outside of Matlab is a nuisance,
because the file format for .mat files is not simple.
