assafmo / joincap Goto Github PK

I rummaged through several programs and scripts to combine pcap files, but your program is the best. I mainly use Kali Nethunter on an android phone and I would like to have this tool on it as well. Could you release an implementation for arm64? Since I have zero in compilation, but I haven’t found any ready-made solutions on the Internet. Thanks in advance.

There can also be a limit of number of packets that can be merged or limit on size of merged file i.e merged file should not be greater then specified limit

Hi
when i run this command :

./joincap-macos64-v0.10.2 -w test.pcap test_*.pcap -v

nothing appear, just created a file with these errors

Hello @assafmo ,

I have been using joincap as a local development tool for merging granular pcap files into larger pcap files. However, when I tried to deploy it onto a linux environment (it was working perfectly on windows locally), I am unable to merge any pcap files. Below is the verbose output, and this is the same output when sudo'd

user@machine:~$ joincap -v -w=output.pcap input.pcap
user@machine:~$ sudo joincap -v -w=output.pcap input.pcap

both yield:

2019/04/17 17:09:20 joincap v0.10.1 - https://github.com/assafmo/joincap
2019/04/17 17:09:20 input.pcap: open input.pcap: permission denied (skipping this file)
2019/04/17 17:09:20 merging 0 input files of size 0 B
2019/04/17 17:09:20 cannot open output.pcap for writing: open output.pcap: permission denied

This happens regardless of user and directory permissions (I'm doing this in the home directory of my user, so it follows that I have read/write privileges). Any ideas as to what is going on here? I would love to get this tool working on this environment (ubuntu 16.04). Any help would be extremely appreciated!

Thanks,
Jonathan

Since this appears to be the only tool currently allowing a directory to specify the source of pcaps, it would be useful to have a "follow" mode where joincap can merge existing files, but watch the final file for growth as well as watch the specified directory for new pcaps to join. The goal would be to allow one tool to write pcaps while joincap to reads and follows what's written in near-realtime for streaming to other tools that consume pcaps.

If implemented, it may also be necessary to have a start-time option that suppresses output of any packets prior to a given date/time. That would allow one to restart an aborted joincap in follow-mode from a given point without needing to clear out already processed files from the source directory.
