Using the nc command you can scan a port or a range of ports to verify whether a UDP port is open and able to receive traffic.

This first command will scan all of the UDP ports from 1 to 65535 and add the results to a text file:

$ nc -vnzu server.ip.address.here 1-65535 > udp-scan-results.txt

This merely tells you that the UDP ports are open and receive traffic.

Perhaps a more revealing test would be to actually transfer a file using UDP.

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

1. Generate and add your key to GitHub
2. $ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
3. $ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
4. $ git config --global alias.logs "log --show-signature" (now available as $ git logs)
5. $ git config --global alias.cis "commit -S" (optional if global signing is false)
6. $ echo "Some content" >> example.txt
7. $ git add example.txt
8. $ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)
