Hi, 

I am new here (but I'we been using Wireshark since the age of Ethereal, and
like it very much !)

Recently I started working on GNS3 network simulator, and one of our
features is to dump traffic to file and keep running.
The PCAP files on hard disk are being continuously updated / written.
Currently I must restart Wireshark GUI every time I wanna see the new
packets coming.

One user (Guy Harris) answered:

"Live capture" involves dumpcap writing to a file *and* sending to
Wireshark/TShark, over a pipe, "there are N more packets" messages.

Would it be possible to add to dumpcap the ability to "capture from a file" ?

Thanks in advance,
-Technologov
