How do I display all listening source and destination http sockets using network command ss?

[indigowinged]

Also see the man page: ss(8) - another utility to investigate sockets

To display all listening source and destination http sockets:

$ ss  -o state listening '( dport = :http or sport = :http )'
Netid    Recv-Q     Send-Q            Local Address:Port           Peer Address:Port
tcp      0          128                     0.0.0.0:http                0.0.0.0:*
tcp      0          128                        [::]:http                   [::]:*

       Available identifiers are:

              All  standard  TCP  states: established, syn-sent, syn-recv, fin-wait-1,
              fin-wait-2, time-wait, closed, close-wait, last-ack, listening and clos‐
              ing.

              all - for all the states

              connected - all the states except for listening and closed

              synchronized - all the connected states except for syn-sent

              bucket  -  states,  which are maintained as minisockets, i.e.  time-wait
              and syn-recv

              big - opposite to bucket
