Hi all,
I'm running a vnc4server install on Ubuntu 12.10. Every time I need to access my VNC server, I have to restart it because I get a "Too many security failures" error. I've tried accessing my VNC server from multiple locations and that hasn't helped. Today, I looked at my log and saw that 0.0.0.0 has been blacklisted. I assume this would be the cause of it, but I don't know how to prevent it from getting automatically blacklisted.

Here's the text from the vncserver log.
