Comment 7 for bug 330310

@Miguel: These commands may show errors Vino through that caused a problem with execution, but the main issue (at least to me) is there is no logging of when a client connected to Vino (either successfully, or failed password). I would like to know the following:

1: Time of connection attempt
2: Source IP
3: Failed password attempts
4: Successful connection time
5: Connection duration.

Also, these needs to be available via System > Administration > Log File Viewer.

kristian is spot-on; this is a security issue. I can't very well tell folks how secure Ubuntu is if I can't properly audit who's logged into the system remotely via Vino (which is the default Ubuntu VNC server)
