Subject: vino: Listens on IPv6 only (net.ipv6.bindv6only=1?)

Date: Wed, 16 Dec 2009 22:44:43 -0800

Package: vino
Version: 2.28.1-2
Severity: important

Reporting this as "important" on the assumption that it may not affect
everyone.  If it does, it easily qualifies as "grave", because "makes
the package in question unusable by most or all users" doesn't seem like
a stretch for a bug that makes vino not work with IPv4.

As far as I can tell, vino now only listens on IPv6.  I can connect just
fine over IPv6, but not over IPv4.

vino-server is unusable.  I do not get a listening socket on ::1, it
(vino-server) shows as listening on :::5900.  Then, when I try and
forward the connection through the ssh tunnel established 
with 'ssh -X -L 5900:[::]:5900 user@host, the vncviewer doesn't
connect to the remote vino-server, the connection 
'seems' to be established but I get no password prompt:

it's the same thing for me....with many computers, and a fresh
install...that's a pity.
if you want to use vino , you must set  in the file
/etc/sysctl.d/bindv6only.conf

net.ipv6.bindv6only = 0

after you can try this commands and you will see that many other services
work now

thank's....

Subject: vino: diff for NMU version 2.28.1-2.1

Date: Sat, 23 Jan 2010 13:39:42 +0000 (UTC)

[Message part 1 (text/plain, inline)]

tags 561440 + patch
thanks

Dear Jordi,

I have prepared an NMU for vino (version 2.28.1-2.1) to use
two (IPv4+IPv6) sockets instead of one, thus work on kFreeBSD
and with the recent netbase changes.

I’ll have it uploaded to according to devref §5.11, patch attached.

bye,
//mirabilos
