netstat

So I’ve been operating FreeBSD servers for about a year now where I work. I’ve come to really like the sockstat command in FreeBSD

# sockstat -l -4

will list every ipv4 address listening in some port and which user the process that is listening to that port is.

In Linux I’ve usually done the same with

# netstat -taupen

netstat -taupen isn’t as ‘clean’ as sockstat in FreeBSD, but I see that

# netstat -tln

give me less info, and I think I’d prefer that one when I simply need to check which ports are in a LISTENING state ( and add -u to show udp as well )
