Hi I was using the VNC bypass script and I got a strange output... Host is up (0.16s latency). PORT STATE SERVICE 5800/tcp open vnc-http 5900/tcp open vnc |_banner: RFB 003.003\x0A\x00\x00\x00\x00\x00\x00\x00\x1AToo many secu... What it means?
Recent version of RealVNC (and some of the other VNC's) include a security mechanism that prevents an IP from connection/authenticating if it has made to many attempts to do so. A simple connection to the port running the service is considered an attempt, and after 5 of them the IP address is blocked. For more information see: http://kb.realvnc.com/questions/23/I%27m+receiving+the+error+%22%27Too+many+security+failures%22.
Also, there is a script that check for VNC without password?
Yes, vnc-info should be able to tell you if the service is missing a password, if your IP has not been blocked.
