FC14; Vino - can't seem to get it working

[Ron Leach]

List, good afternoon,

Hopefully, I've overlooked something, but cannot think what.

Installed F14 on a Samsung NB30 netbook, from the RC2 XFCE CD.  'yum 
update' last night (it updated nearly 450 programs/libraries). 
Installed Vino (vino-2.31.91-1.fc14) but cannot log into into the 
netbook's desktop from another machine.

(Had first tried vino-2.32.0-1.fc14 from 'test updates' repository, 
but when I failed to log into that, reverted to this slightly earlier 
version which is from the main F14 repository.)

Netbook is connected to local network, replies to pings, and can 
access internet.  Firewall set to 'trust' eth0 and wlan0; and tried 
with firewall both enabled, and disabled.  Same result, VNC client 
reports failure to connect.  (VNC client has unrestricted access to 
the network, and can access all 4 other desktops on the network, 
without problems.)  A different VNC client (Krdc on Debian/KDE) 
reports 'no server running at that address/port (5900)'.

Noticed that, on F13 (on another machine), had to run 
'vino-preferences' before a VNC client could log in.  Have run 
'vino-preferences' on the netbook, allowed 'control of machine', 
assigned a password, and tried with 'configure network to 
automatically accept connections' either set, or unset; same results.

vino-preferences 'checks connectivity' and sometimes reports
(i) 'local network only, using name localhost' (which surprised me 
because on the other machine using F13 it reports the machine name and 
its IP address), or
(ii) it sometimes says the machine can be accessed using our external, 
routable, IP address (which it cannot, because that's blocked at a 
gateway and the internal network is NATted and there are no 
port-forwards set).

Vino doesn't appear in the XFCE 'system services' graphical list. 
Maybe it isn't running, just as KDE surmised.

Could I ask - how should I check if it is running, and is there a 
specific command to start vino running?  (Under F13, it seemed to run 
after vino-preferences was run.)

Thanks for reading this far, grateful for any suggestions.

regards, Ron
