Duplicate entries for Hosts nearby

[Alexey Kotlyarov]

Binary package hint: vinagre

The Hosts nearby machine list shows all - at least Mac OS X - machines twice (both VNC and SSH).

How to reproduce:
1) Enable Screen Sharing on a Mac OS X machine
2) From the same network, open Vinagre

Expected results:
Mac OS X machine is listed once for VNC and once for SSH.

Actual results:
Mac OS X machine is listed twice for VNC and twice for SSH.

More:
Go to Edit -> Plugins, uncheck SSH (or VNC) and check it back. Now Mac OS X machines are listed 3 times for the selected plugins. Repeat for more.
Quickly unchecking and checking VNC multiple times crashes Vinagre.

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version. Thanks in advance and sorry for the late response.

Nothing has changed in Natty. The duplicates are still there.

I'm sorry, the latest comment was for another bug. Unfortunately I have no way of checking this one.

Was about to report this too, yes I'm seeing this, and have seen it for the past few Ubuntu versions, but as it tended to happen when I was distracted by going off to do something and it didn't stop me, i never got around to posting a bug about it before.

I'm using 11.04 Natty all up to date and I'm still seeing this. Also, often, one of the pairs of entries doesn't work; the connection fails immediately with "Connection closed" and no further information in evidence.

Also, it's not restricted to its view of remote Macs, as the screenshot in the attachment should demonstrate. For this I must confess my network naming scheme... ;-} In the attached screenshot, fluttershy, octavia and twilight are all Linux Ubuntu Natty machines, the others are Macs.

However, a possible reason for *that* is that I altered the avahi configuration on the Linux machines to make them more co-operative on a predominantly mac network - ie: they behave the same way with respect to the file and screen sharing visibility in the mac Finder, and also show up as sftp servers on nautilus the way macs with login sharing enabled do. And clearly they now emulate macs so faithfully in this respect that they trigger the same bug in vinagre. :-)

The avahi changes are, in total:

in /etc/avahi/avahi-daemon.conf:
disable-user-service-publishing=yes

This is to kill ubuntu's remote desktop *server*'s way of advertising its services, which can't otherwise be disabled or configured - there are other bugs about that. This change hasn't actually been done on this machine as I don't share out the desktop from it, so the problem doesn't arise; but the double-entry for its ssh+sftp service still shows up. (I'm using fluttershy, and there it is, two ssh entries at the top.)

In the attached tarball are also the extra .service files added to /etc/avahi/services if the associated services are actually enabled. Included as a way to reproduce the problem if you don't have macs on your network. :-) The problem if you were to tell me that these .service files are buggy is that the same bug is hard-baked into Mac OS X.

NB: As the screenshot implies, this is on i386 Natty, on a netbook; I also, like the original reporter of this bug, encounter it on amd64 Natty machines, so architecture seems irrelevant.

And other versions back at least to Lucid (still have one of those sitting around with a desktop).

Point of reference: At least one other VNC client (specifically in my case iTeleport on iPhone and iPad) also has zeroconf discovery of nearby vnc servers, and does *not* experience these doubled-up entries. Screenshot attached demonstrates - or rather doesn't demonstrate the bug, indicating it's probably not a fault with what's being advertised.
