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.
Being the guy who develops SplitCap I can assure you that it runs on Linux -- just make sure to install the mono framework. Here's a quick howto for Ubuntu: sudo apt-get install libmono2.0-cil mono-runtime wget http://sourceforge.net/projects/splitcap/files/latest unzip SplitCap_1-9.zip mono SplitCap.exe -r dumfile.pcap There is a minor bug when running in Linux though, as the split files aren't properly put into a subdirectory. But I'll make sure to have that fixed for the next release of SplitCap. Feel free to let me know if you have any additional questions regarding SplitCap! /erik
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 () wireshark org (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.

Your best bet i s probably editcap, you can splice the resulting files back together with mergecap should you need it.Another possibility is splitcap: http://www.netresec.com/?page=SplitCap. - Chris P.S.
