vncserver setup

Hi,

I currently run a RH 9 Linux server, which pretty much has not been upgraded
past that point. I started looking for a Remote Desktop program to allow me
to use the Linux desktop from my Windows XP notebook and desktop (mostly
just internally behind a router firewall - 192.168.0.X network). After
searching a bit I came across vncserver. I searched the original RH9 discs
that I have and found vncserver 3.3.3r2-47. So, I installed it.

It seems as though it works fine. When I run "vncserver" it reports a port
number and seems to start just great. When I try to connect from my windows
desktop, though, it doesn't connect correctly. I run vncviewer, and it asks
me for the IP and port, it just disappears. Using Firefox also returns an
error. I am using port 1, 5801 and 5901 for the correct service. I took a
look at the logfile for vncserver and it reports that the connection was
refused. I double checked iptables and removed all firewall rules for
testing purposes. Then I also tried running vncserver as root and a normal
user. I get the same problem each time. Now, since I am not leaving my
LAN, the router firewall shouldn't come into play. The firewall on the
Linux server is disabled. Anyone have any idea why I can't connect?

Thanks,
Scott

vncserver doesn't actually report the port number; it reports the VNC
display number (starting from :0), which corresponds directly to a pair
of port ranges starting from 5800 and 5900.

It's not the port number, it's the display number (starting from 0).

These ports equate to display :1.

Ah. Did you set a vncserver password? The command is "vncpasswd"

Chris

No, I guess that the password I already set was correct. I used the
vncpasswd command, set it, and got the same result. Still refuses the
connection. Again, I cleared the iptables so that nothing was in there.

Can you post the actual output it produces, please.

That's typical of the situation where you're trying to connect to a
non-existant server/port.

So that should be vncviewer remote_server:1

Can you provide the exact output, please.

What happens if, on the box that you normally run vncviewer on, you run
this command (to exit, you can use Ctrl/] then q):

telnet remote_server 5901

Chris

This is the exact output that I have been getting...

10/03/06 09:20:47 Refused connection from client 192.168.0.2

Now, I am not sure, should I be able to use the 192.168.0.3:1 command to
connect via internal LAN? It is just that I was wondering if for some
reason it might be rejecting me because of that. I notice that the log
doesn't say anything about the IP address, just the localhost. I pretty
much just installed the RPM and didn't configure anything. Like I said, it
seemed to work ok, just won't connect.

Just trying to get this strait a little, too. If I am using :1 to connect,
in which instances would the 5801 and 5901 be used? Externally? As in when
I was trying to get on from outside the LAN? Maybe I should wait for that
question until I can at least connect with an internal computer.

Thank you for all your help,
Scott

We have very bad experiences with tight VNC. We use Realvnc from
www.realvnc.com. Give it a try!
