Hi Marc, I am the original user. Thanks to Alan for filing the bug
report. I'll clarify a couple of things. The machine (running Ubuntu
9.04) is on a typical domestic 192.168.1.x network, and *does* have
internet access via a typical domestic Comtrend router. The router is
not configured to forward any ports, nor do I want it to be.
Using the GUI too, after making the internet check, it displays "Your
desktop is only reachable over the local network. Others can access your
computer using the address localhost".
Perhaps slightly atypically, I have given it a static IP address; in
doing so I seem to have got network manager thoroughly confused. It's a
laptop in a docking station so it has two wired ethernet interfaces and
one wireless.
Despite ifconfig showing a valid interface:
eth1 Link encap:Ethernet HWaddr 00:06:xxxxxxxxx
inet addr:192.168.xxxxxxxx
(and so on) and having full normal internet access, network manager lists the
wired interface that I am using as being "not managed" and that therefore (as
far as it's concerned) there is no network connection at all, as the other two
are currently unused.
So I've commented out the entries in /etc/network/interfaces setting up
a static IP and gone back to a DHCP address and full management from
Network Manager. But it's still coming up with the message about
"localhost" and there's still no listening port or process listed in
"netstat -nap".
I'm guessing the issue here is something to do with Network Manager
getting in a muddle about what is up and running, and vino using bad
information from Network Manager. As I said, it's a laptop, and with
the wireless interface sometimes appearing as eth1 and sometimes as
eth2, depending on whether it was plugged into the docking station,
things seemed to get very confused.
As regards the outbound network connection issue: it is not clear at all
(even to someone that's been using both VNC and Ubuntu for years! (just
not the built-in server)) that "vino-preferences" is legitimate, nor is
it clear at all that the IP it connects to is legitimate.
