I'm running ubuntu 8.04 with vnc4server.
You might like to update, 8.10 is out and should not harm you.
I'm trying to get my vnc server to listen on a specific interface. I
don't want it listening on localhost, I want it listening on a virtual
tun interface I setup, tun0, ip 10.6.7.0.
Why not localhost? There is absolutely no harm in that.
I tried adding the "-interface" option to the vnc4server script but Xvnc
doesn't like it, "Unrecognized option: -interface".
Read the manual for the available options. `Xvnc --help` can also list them.
Be noted, Xvnc (and every other X11-server) does need access to
localhost (127.0.0.1) as that is used in the X11 communication. However,
I have to admint, there are instances where localhost is not used, but
as you ask this, you are no X11 guru.
Hence, better not restrict Xvnc from using the localhost (127.0.0.1) route.
I also tried starting vnc4server like this, "vnc4server :1 -interface
10.6.7.0", but that didn't work either, "Unrecognized option: -interface".
just a question: have you installed vnc4server from a download or from
the ubuntu repositories? Ubuntu comes with a bundled vnc, best start
using that. Once it works, try tweaking by altering options and/or
replacing the binaries.
How would I make vnc listen on a specific interface?
First get it going, then it is depending on the way you use it. As far
as I know, the best way to avoid vnc-trafic over a port or nic is to use
a firewall to restrict it. The origional (now antique) vnc
implementations did not have any security what so ever. Current
implementations might have added security but donnot rely on it.
