Re: Packet Size limited during capture message

The snaplen was set to 150 when using tshark.
I see a Frame that says (for example):     Frame 7 (341 bytes on wire, 
150 bytes captured).

But looking at the detailed view of this packet...  it actually looks 
good until you get to the end... it is truncated.

And NO... the pcap file doesn't crash when the dissector is removed. I 
can load about 70% of it and hit stop....but
if I let it go any further it will crash wireshark.

Like I said in my email to martin.... if I followed all the wireshark 
coding standards... shouldn't the code handle this..??

What should be my next step..??

Thanks for your help

Brian
