Hi,
I currently had the follow issues with ss where it was not displaying the UDP listening ports.This was on:
Linux 4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 GMT 2017 armv7l GNU/Linux ss -ul State Recv-Q Send-Q Local Address:Port Peer Address:Port netstat -ul Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State udp 0 0 0.0.0.0:mdns 0.0.0.0:* udp 0 0 0.0.0.0:bootpc 0.0.0.0:* udp 0 0 0.0.0.0:55887 0.0.0.0:* udp 0 0 192.168.1.80:ntp 0.0.0.0:* udp 0 0 localhost:ntp 0.0.0.0:* udp 0 0 0.0.0.0:ntp 0.0.0.0:* udp 0 0 0.0.0.0:46739 0.0.0.0:* udp 0 0 0.0.0.0:snmp 0.0.0.0:* udp6 0 0 [::]:mdns [::]:* udp6 0 0 [::]:40880 [::]:* udp6 0 0 fe80::bcdd:e603:7d8:ntp [::]:* udp6 0 0 localhost:ntp [::]:* udp6 0 0 [::]:ntp [::]:* I hope I have found the proper way to report this issue.
