How to view UDP and other protocol connections?

netstat is weak and can't show udp connections and most other protocols, use "ss" which is what netstat should have been:

The "-u" switch stands for udp, here's a list of other options:

Usage: ss [ OPTIONS ]
       ss [ OPTIONS ] [ FILTER ]
   -h, --help        this message
   -V, --version    output version information
   -n, --numeric    don't resolve service names
   -r, --resolve       resolve host names
   -a, --all        display all sockets
   -l, --listening    display listening sockets
   -o, --options       show timer information
   -e, --extended      show detailed socket information
   -m, --memory        show socket memory usage
   -p, --processes    show process using socket
   -i, --info        show internal TCP information
   -s, --summary    show socket usage summary

   -4, --ipv4          display only IP version 4 sockets
   -6, --ipv6          display only IP version 6 sockets
   -0, --packet    display PACKET sockets
   -t, --tcp        display only TCP sockets
   -u, --udp        display only UDP sockets
   -d, --dccp        display only DCCP sockets
   -w, --raw        display only RAW sockets
   -x, --unix        display only Unix domain sockets
   -f, --family=FAMILY display sockets of type FAMILY

   -A, --query=QUERY
       QUERY := {all|inet|tcp|udp|raw|unix|packet|netlink}[,QUERY]

   -F, --filter=FILE   read filter information from FILE
       FILTER := [ state TCP-STATE ] [ EXPRESSION ]

ss -u
