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.

Gradle tab completion script for Bash

A tab completion script that works for Bash. Relies on the BSD md5 command on Mac and md5sum on Linux, so as long as you have one of those two commands, this should work.

Usage

$ gradle [TAB]

OpenVPN .ovpn manipulation.

This is how you can take an OpenVPN .ovpn config file and extract the certificates/keys required to import the profile into NetworkManager.

• Download the .ovpn file. Save it somewhere you can store it permanently (I use ~/.vpn).
• Copy from between <ca> tags into ca.crt, remove <ca> tags.
• Copy from between <cert> tags into client.crt, remove <cert> tags.
• Copy from between <key> tags into client.key, remove <key> tags.
• Copy from between <tls-auth> tags into ta.key, remove <tls-auth> tags.
• Remove the line "key-direction 1"
• Above "# -----BEGIN RSA SIGNATURE-----" insert the following lines.
