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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to vino in Ubuntu. https://bugs.launchpad.net/bugs/1281250 Title: VNC accessible for Windows machines only with encryption disabled Status in GNOME Remote Desktop: Confirmed Status in “vino” package in Ubuntu: Triaged Status in “vino” source package in Trusty: Triaged Status in “vino” package in Fedora: Unknown Bug description: Since a recent update, it is impossible to connect to my Ubuntu box using VNC from a Windows machine unless I disable encryption on the vino server. I tested up-to-date tightVNC client and TigerVNC client on the Windows machine, with the same result. As soon I try to connect, I receive the following error: [ 5872/ 6448] 2014-01-20 12:11:18:247 List of security type is read [ 5872/ 6448] 2014-01-20 12:11:18:247 : Security Types received (1): Unknown type (18) [ 5872/ 6448] 2014-01-20 12:11:18:247 Selecting auth-handler [ 5872/ 6448] 2014-01-20 12:11:18:247 + RemoteViewerCore. Exception: No security types supported. Server sent security types, but we do not support any of their. So it seems that the update changed the security type of vino to a new one. I searched for a way to go back to the old one (until the clients catches up) with no avail. A solution is disabling the encryption completely, by gsettings set org.gnome.Vino require-encryption false ...but this is subotpimal. Is there a way to switch the encryption back to the old one?
