List Open Ports on FreeBSD

Wed, 08 Apr 2020 12:13:07 +1000

On Linux to list running services and open ports, I either use netstat or ss (socket stat?) most recently.

Though netstat is available on FreeBSD, the syntax is completely different.

Today, I have the need to list the running services with the port display. On FreeBSD, we can do this using sockstat command.

root@bsd1:~ # sockstat -4 -l
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS      
minio    minio      49274 10 tcp46  *:9000                *:*
root     sendmail   675   4  tcp4   127.0.0.1:25          *:*
root     sshd       672   4  tcp4   *:22                  *:*
ntpd     ntpd       616   21 udp4   *:123                 *:*
ntpd     ntpd       616   22 udp4   149.171.180.154:123   *:*
ntpd     ntpd       616   25 udp4   127.0.0.1:123         *:*
root     syslogd    523   7  udp4   *:514                 *:*

Here are some other options which can be passed to the sockstat command:
