Bug Description

When attempting to VNC into 14.04

vncviewer[6008]: CConnection: Server offers security type [unknown secType 18](18)
vncviewer[6008]: CConnCommon: close: Unable to connect to VNC Server using your chosen security setting. Either upgrade VNC Server to a more recent version from RealVNC, or select a weaker level of encryption.

Have attempted to connect with the firewall disabled.
I have upgraded and tried multiple VNC clients.

vino 3.8.1 0ubuntu1

Guys,

The problem is simple.
If you take a Wireshark trace you immediately see the issue.
You will have to filter on VNC.
The supported security type which is given for 14.04 is "type 18, TLS".
For 13.10 we see two types, "type 18, TLS" and "type 2, VNC".

The "type 2, VNC" is used by your VNC viewer.
So adding type 2 in the proposed supported security types will solve this bug.
