How do I display ipv4 and ipv6 socket connections using the network command ss?

indigowinged

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

$ ss -4 state established
Netid   Recv-Q    Send-Q        Local Address:Port         Peer Address:Port
tcp     0         64            xx.xx.xx.xx.:ssh        xx.xx.xx.xx:64716

None to display here.

$ ss -6 state established
Netid   Recv-Q    Send-Q        Local Address:Port         Peer Address:Port

       -4, --ipv4
              Display only IP version 4 sockets (alias for -f inet).

       -6, --ipv6
              Display only IP version 6 sockets (alias for -f inet6).
