Shows live outboud connection attempts and/or suceess, refreshing every 0.5 seconds

watch -n0.5 -d "netstat -nafo | grep -v -E 'LISTENING|||\[::\]:|\[::1\]:'"
This is very handy for troubleshooting apps connection to internet. Shows an app's outgoing ip/port before and after connection established. Run this command and init the app you're investigating. I used that when trying to understand what is the destination's ip/port needed to open in firewall, for a specific VPN app. Similar for windows cmd: netstat -nafo | find /v "LISTENING" | find /v "" | find /v ""
