I was working with Squid proxy cache in pfSense and needed to find the version of my squid proxy server so that I could determine where the binaries are located. I couldn’t find it anywhere in the pfsense console (comment below if you know where) so what I did was enabled ssh and connected to my pfSense server using WSL. Running uname I found out pfSense is running on FreeBSD, so I proceeded to determine how to check squid version in linux BSD.
FreeBSD Check Squid Version
I used the following command to check squid version in linux BSD
As you can see I determined squid version to be 3.5.27.
