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.
Previously I wrote a brief article on 0trace in Backtrack 4 which can be located here however in the process of writing an updated article for Backtrack 5 I noticed that 0trace was no longer working. Every single time I would attempt to run an accurate trace through a firewall the results would come back empty and display “Probe rejected by target.” At first I was thinking maybe companies have really tightened down their firewalls however that didn’t make any sense because of how 0trace works using a standard port such as port 80 to allow traffic to pass because the servers function is to serve web pages. Below I describe the error in more detail and how you can resolve it.
