I did it twice, the extra time to get the column headers.  Splicing the two together...

Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address State       PID/Program name
tcp        0      0 0.0.0.0:111             0.0.0.0:* LISTEN      1/systemd
tcp        0      0 192.168.122.1:53        0.0.0.0:* LISTEN      1252/dnsmasq tcp        0      0 0.0.0.0:631             0.0.0.0:* LISTEN      1081/cupsd tcp        0      0 127.0.0.1:25            0.0.0.0:* LISTEN      2068/sendmail: acce
tcp6       0      0 :::111                  :::* LISTEN      1/systemd
tcp6       0      0 :::631                  :::* LISTEN      1081/cupsd

Is this what it should be?  Anything I should do?  I guess it's not relevant to the current matter, but should cupsd be in the list twice?
