           Summary: netstat on Linux has a flag to find hte program that
                    does portbinding, FreeBSD does not
           Product: Base System
           Version: Unspecified

                OS: Any

          Priority: ---

netstat on Linux has a flag that allows you to identify the program that is
binding to the port, you can run "netstat -pan" and the -p flag tells you the
program that makes the portbinding.  This can be used to find reverse shells
which I have witnessed being used by state threat actors.  It is very hard to
find a reverse shell on FreeBSD because this flag is missing, and if you look
at the man page there is no correlating flag that does the same thing.  I
realized this is a feature request but the Freebsd source code is the basis of
super-secure OpenBSD and MacOS, and so it makes sense to push the change to
improve netstat analysis to FreeBSD and let the others follow course.  

Thank you,

Michael Lazin
