[yocto] Poky build errors, help is needed

[Zoran Stojsavljevic]

Please, try to check trijicon.com firewall: which services are
available, which are not.

Please, read the following:
https://serverfault.com/questions/309052/check-if-port-is-open-or-closed-on-a-linux-server

And also the following:
https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

Please, explore and learn about CLI nmap (very powerful) command.

Hope this helps,
Zoran
