Steps to enable GPG signing of git commits.

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)

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

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.

Gradle tab completion for Bash. Works on both Mac and Linux.

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]

UDP Port Troubleshooting using netcat
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.
