[Desktop-packages] [Bug 1281250] Re: VNC accessible for Windows machines only with encryption disabled
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.

@nitrogen dream: reading here: https://sourceforge.net/p/tigervnc/code/HEAD/tree/rfbproto/rfbproto.rst #vnc-authentication, with type 2 the only thing that is encrypted is the VNC password, which is, honestly, my least worry. All the keystrokes in the session (including your bank password) is then sent unencrypted on the local wire. Will check SSVNC; but this is similar to what I am doing now, having a ssh tunnel in the middle.

[Desktop-packages] [Bug 1281250] Re: VNC accessible for Windows machines only with encryption disabled
@Holger: yes --- I just noticed it too. I humbly suggest that Canonical or Redhat help the vino developers to add a more common encryption type to the vino server. It is the default (and the facto only) remote vnc server in our system, and in its current state forces everyone to connect **in clear** on the local network. All what you type is sent as is. I have worked around it wrapping the thing in a SSH tunnel, but still, it's sensible to local attacks and I think it's not a solution for the average user. @Sebastian, I am not sure if this is a security thing --- after all, before the switch, all the connections were silently made without encryption, but it's scary nevertheless --- sniffing for traffic on port 5900 is easy enough. -- 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.

Upstream comment: I think that the TLS security type (18) is rather uncommon, but gtk-vnc supports it.

[Desktop-packages] [Bug 1281250] Re: VNC accessible for Windows machines only with encryption disabled
Well, downloaded it (virt-viewer, I mean). Tried to connect to a remote machine but no dice --- it just show a window, asking for a connection URI, I tried 200 combinations... No documentation handy available either. Seems to be thought just for managing virtual machines, so it doesn't seem a general VNC viewer tool. So I think that the only option now is a) having a VNC with almost no interoperability with Windows or b) re-defaulting to no encryption Really, I do not know which one of the two options is the worst one. -- 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.

[Desktop-packages] [Bug 1281250] Re: VNC accessible for Windows machines only with encryption disabled
I agree that the best possible solution would be for the Windows clients (at least TigerVNC and TightVNC) to catch up. Unfortunately this has not happened; for the time being it would be much better if vino could offer the option to go back to the previous Security Type when the client does not support the new one. The only solution now is disable the encryption completely; I resorted to a loop back ssh connection so that there is no clear traffic on the wifi, but I still need to do the local step with vino in clear way --- almost safe for me because I do not have other local users, but you never know... -- 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 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.

[Desktop-packages] [Bug 1281250] Re: VNC accessible for Windows machines only with encryption disabled
Sebastian: no. the default is to use encryption. But after updating vino (do not remember at which point), vino changed the security type to a new one (at least, I think); the connection stopped to work with the error reported above and the only solution to have it back was to disable encryption. What I *suppose* happened is that the vino server upgraded the encryption algorithm and the clients have still to catch up; the problem is that there seems no way to say vino to use an old encryption --- it just works with the type 18 or none. -- 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 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.
