VNC Fatal server error: could not open default font ‘fixed’

I needed to use some GUI tools recently for testing hard drives in a large RAID group on a CentOS Linux server that I only have remote access to so I decided to install VNC temporarily. The server has never had a GUI installed so I first installed the Gnome Desktop Environment, then installed VNC, configured VNC, and last attempted to start VNC but I received an error. The error was complaining of the default fonts not being in the proper location however the error output was excellent and allowed me to create a quick symlink to resolve the issue. Below I describe the error in more detail followed by the one command resolution.

How to Change Timezone on Linux

Changing the timezone on Linux is easy. The timezone within Linux is set by a symbolic link located in the /etc directory which needs to be changed to the new timezone. Once this is changed the time needs to be synced to a time server. I recently moved from Las Vegas to Louisville and had not changed a Linux server to the new timezone. Follow the steps below and the new timezone will be set and updated.

  1. Backup Current Timezone: Issue the below command on your server to backup the current timezone information just in case there are issues.

    1. cp -p /etc/localtime /etc/localtime.bak
