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

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

Display all source and destination ssh sockets.

$ ss -a '( dport = :ssh or sport = :ssh )'
Netid State   Recv-Q   Send-Q      Local Address:Port       Peer Address:Port
tcp   LISTEN  0        128               0.0.0.0:ssh             0.0.0.0:*
tcp   ESTAB   0        64          xx.xx.xx.xx:ssh      xx.xx.xx.xx:64716
tcp   LISTEN  0        128                  [::]:ssh                [::]:*

       -a, --all
              Display both listening and non-listening  (for  TCP  this  means
              established connections) sockets.

The port numbers can also be used.

$ ss -a '( dport = :80 or sport = :80 )'
Netid  State    Recv-Q   Send-Q      Local Address:Port     Peer Address:Port
tcp    LISTEN   0        128               0.0.0.0:http          0.0.0.0:*
tcp    LISTEN   0        128                  [::]:http             [::]:*
