Mac OSX Ultrawide Monitor Setup with SwitchResX


Sep 26, 2016 by derek

When I first got these nice looking LG Ultrawide displays here at work I spent a considerable amount of time getting the resolutions right. All in all I wound up having to use SwitchResX to get them to work properly. That was a while ago and I forgot the torment I went through to get it right. 

Well, with the latest update to Sierra, I got a pleasant reminder. So, here you are, the SwitchResX settings I finally got to work with these puppies.

Chicken of the VNC - Unknown authType 18


Aug 02, 2016 by derek

Was setting up some remote access to my Xubuntu 14.04 box tonight. While trying to connect using Chicken of the VNC I received this error:

Unknown authType 18

To fix, hop on the server and disable the encryption:

gsettings set org.gnome.Vino require-encryption false

Should be able to connect now.

Verifying SSL Certificate, Key, and CSR


Jun 22, 2016 by derek

Use these openssl commands to verify that your SSL key, certificate, and certificate signing request (CSR) all match up.

openssl x509 -noout -modulus -in certificate.crt | openssl md5
openssl rsa -noout -modulus -in privateKey.key | openssl md5
openssl req -noout -modulus -in CSR.csr | openssl md5

If they all match up, you're good to go!
