thanks, this looks like it will work

2020-04-27 15:43:27 +0000 marked best answer Limiting tsharks /tmp file

I have a long running tshark session. I don't create a local file but instead process the results of StdOut.

Recently I've found that tshark is creating a file in /tmp named wireshark_INTERFACE_TIMESTAMP_RANDOMID.pcapng. Because I am taking a long running pcap this file grows quickly to the point the machine runs out of disk space.

Does anymore know of a way to:

  • Limit the size of this file?
  • Stop it being created?
  • Rotate it after X?

The man page does define a 'ring buffer' mode however i'm not actually producing any capture file. I want these setting for the tmp file, ideally stopping it all together.

I don't really want to kill the process, remove the file and restart capture as I will lose data.

I think tshark is picking up the configuration file for Wireshark where the correct parameters are set. Moving the confi

Even more annoying. Decrypting works on a Windows box but fails on a Linux box. Same version. There are some deep proble

worth mentioning that this is broken on most version of tshark you'll encounter. I needed to use the latest build.

This looks like a bug in tshark. I'm going to report this.

The problem here isn't decrypting packets. The problem is PDU export using tshark.

Done it. Can someone tell me why this makes it work??? tshark.exe -r sample.pcapng -o "ssl.desegment_ssl_records: TRUE"

Yep your right that was a type. Correcting it makes things worse! The pcap isn't even decrypted.x

Interesting. My PCAP fails to decrypt after running it through TraceWrangler. The packet with the ClientHello is broken
