Dear Harris,

Thank you for your help. I very appreciate it. I found that my problem was caused from the reason 1 as you suggested.

Best Regards.

By either

                 1) capturing either on Ethernet or a PPP interface on an OS
                    where libpcap supplies PPP packets as PPP or fake Ethernet
                    packets (note that Linux is *NOT* such an OS);

                 2) if you are capturing on one of those, getting a newer version
                    of Ethereal (it didn't handle some types of PPP captures with
                    PPP headers in some older versions);

                 3) patching the TCP Graph code to use the "tap" mechanism rather
                    than parsing of the link-layer, IP, and TCP headers itself;

                 4) patching the TCP Graph code to handle the link-layer headers
                    for the type of network on which you're capturing.

If you do 3) or 4), send us the patch.

The error message needs to be changed to be "Selected packet is not a
TCP segment on Ethernet, PPP, or raw IP", or something such as that.
