View Full Version : [ubuntu] Someone is trying to log in to vnc

May 20th, 2008, 08:33 PM
Today I have been been getting popups from vnc, with misc IP's trying to connect to my laptop...

What I suspect is that someone has been scanning my IP range and checking if someone has port 5900 open... Or else I have no idea why my computer is under attack...

Thank god I have my vnc both protected with password and that I have to confirm the access from the desktop of my laptop....
But since I get this popup window to confirm the access to my desktop, then doesn't that mean the user has made it past my password? :confused:

Has anyone else been experiencing this?

Here is a screenshot of one of many popups I have gotten...

I regularly see attempts to connect to the default vnc port in my router logs. It happens for every remote control app available.

I have no idea if that message means they authenticated successfully though.

EDIT: I just tested, connecting from my desktop to my laptop. I only got the popup you show if I enter the correct password. If I enter a wrong password, I just get an authentication error from vncviewer, and no popup.

Leaving VNC open to the Internet is brave. The best solution is to restrict it to local connections only and use SSH port-forwarding to connect from a remote system.

Assuming you have secure SSH keys, of course...
