FreeBSD, sockstat to check listening ports

FreeBSD can check the listening ports for you. Be sure to understand that your computer is offering services that are secure and reliable.

sockstat -l

(netstat | grep LISTEN)

To check your login log,

grep -ir ssh /var/log/*
grep -ir breakin /var/log/*
grep -ir security /var/log/*
