VNC Password on the server
***
allowed only 8 caracters
and VNC Server do not have any default password from
factory ***
examples: 12345678 or abcdefgh or 1234abcd or Ultr@VNC
Message after
install: VNC default password not set
VNC Server won't let you connect without supplying a
password unless the server is explicitly configured to
use No Authentication.
"No Authentication" option is NOT recommended as it is a
serious security risk. Use it only if you know exactly
what it implies...
To configure the WinVNC server password:
- Right click on the VNC Tray icon (if no icon, Run
Start Menu/programs/UltraVNC/UltraVNC Server)
- In the password field, enter your password
8 chars is recommended. Choose a password as a mix of
special characters ( !@?!{... ), digits and letters so
it's hard to guess, and reduces the risk of dictionary
brute force attack.
(when entering the password, you can see the classical
**** chars (or ||||) used to hide what you are typing)
- Click "Ok"
- You can know connect to this server using a vncviewer
and the chosen password
- UVNC 3.3.6
based alpha/numerical password is 8 caracters maximum
(no respect this point should always fail with dsmplugin
enabled)
UltraVNC is based on VNC 3.3.6 but also features
MS-Logon authentication that allows 32 characters
password. So it's always better to use MS-Logon method
if you can.
* The MSRC4 Encryption plugin adds another level of
security for the authentication:
- It requires a key file on both sides: a viewer that
doesn't have the (your) good key file can't even start
to try to authenticate.
- It encrypts the authentication handshaking process
between the viewer and the server.
So it is recommended to use this plugin to get even
stronger authentication security.
