Hello!
Is there an easy way to install Ngrep? Seems there is no official port.
Thanks!
Like any other tool that is not available -> compile it by yourself. You can find the instructions here:

Please note that make on FreeBSD and Linux are different. You may have to install gmake and use that instead of make.
