Upstream comment "I guess that the problem occurs after the default was changed to require encryption:
https://git.gnome.org/browse/vino/commit/?id=f37ca213fda500ea2f93d005e945644c2f2e5721 For whatever reason, that fails with some clients. If you want Vino to work with those clients new authentication types need to be added. There is some information about the protocol and security types at: http://sourceforge.net/p/tigervnc/code/HEAD/tree/rfbproto/rfbproto.rst I will not have time to add the security types in the near future." ** Changed in: vino Remote watch: Red Hat Bugzilla #981984 => GNOME Bug Tracker #728267 ** Also affects: vino (Fedora) via https://bugzilla.redhat.com/show_bug.cgi?id=981984 Importance: Unknown Status: Unknown -- 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: Unknown 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?
