Is there a way to turn off TCP reassembly in tshark? I'm running tshark on multiple files using a script on a Linux server, so I can't use SplitCap.

And it also doesn't seem like I can split up the files with editcap. Whenever I tried to do that with the large pcap files, I got empty output files (24 bytes) instead. I'm not sure if it was due to the large file size.

As for replying to old threads, I'm sorry about that. I didn't know I was doing that, because I was posting only from emails. I thought I just needed to send to wireshark-users@xxxxxxxxxxxxx (using my old posts so I could reference the email address) and a new thread would be created. I'll be sure not to do that again the next time I post a new thread. Sorry!

Another possibility is splitcap: http://www.netresec.com/?page=SplitCap.

P.S. This entire thread is buried on page 3 of the gmane archives under the
30 May 2013 12:09 thread entitled, "Editcap 1.2.15 not working", which
itself is incorrectly threaded under the 30 Jan 2013 11:11 thread entitled,
"Understanding SMB flow in Wireshark", all of which were started by Rayne.
Please start a new message/thread instead of replying to old threads and
changing the subject line.
