SNGREP would be a great tool to have!

Hello all,
I was wondering if SNGrep or something similar is available on pfsense.
This would be amazingly helpful when trying to troubleshoot VOIP issues without needing to download a PCAP.

@thoxle Yes.

It's in the FreeBSD package tree...
https://www.freshports.org/net/sngrep/

caveat: Install things like this at your own risk!

e.g. amd64 (or aarch64, etc)

fetch https://pkg.freebsd.org/FreeBSD:12:amd64/quarterly/All/sngrep-1.4.8.txz
pkg add ./sngrep-1.4.8.txz

Remember, if you get this error:

Couldn't activate capture: BIOCSETIF failed: Device not configured

It's because FreeBSD doesn't support 'any' for capture interface the way Linux does.
Use the -d flag and pass an interface name, e.g.

sngrep -d mvneta1

Here it is running on an SG-2100...

@kiokoman Do you have a link fo FreeBSD 14? Your link was able to fetch but unable to install because it is the wrong architecture "pkg: wrong architecture: FreeBSD:12:amd64 instead of FreeBSD:14:amd64"
