Xvnc not started ??


Hi, I installed VNC server on RHL 9.0. Now I want to access the linux box remotely through vnc. I have XFree86 intalled on the box.
Now when I execute -

#vncserver

it gives me an error that -

[root@mydomain /]# vncserver

Couldn't start Xvnc; trying default font path.

New 'X' desktop is mydomain.com:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/mydomain.com:1.log


What could be the reason?
Thank You.

It think it has started.

What does the output of this show:
netstat -nlp | grep vnc

That means that it has started and is listening on port 5901. 5801 is the webviewer and 6001 is the X server. You should now be able to connect to it from another machine if you can't then make sure you don't have a firewall blocking requests.

And how would I know if a firewall is blocking the request?
Thank You.

found it -- iptables --list

but am not sure what to look for in this ... maybe an entry with a DROP? are those the entries that don't allow the transferring of packages?

thanks

Can you post the output of iptables -L

OR

If you don;t have any special pre defined rules for internet sharing etc then try just removing all rules:
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -F

If this works and you want to be a bit more secure:
# Drop all connections by default
iptables -P INPUT DROP
# Accept current connections
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
# Accept connections to certain ports eg 5901
iptables -A INPUT -p tcp --dport 5901 -j ACCPT

I figured it out. Thanks a lot for your help. I just needed the pointer in the right direction.

Here's what I modified -

Chain Cid3EB05FFB.0 (2 references)
target prot opt source destination
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW multiport dports 5901,10000,25,80,22,21,53,993,143,443,110,3306,8443,995


So, now I am connecting to VNC. However, as I read on some other Thread on this forum, it is showing the command line based screen with a mouse pointer. So,
1) I'll probably have to install KDE/GNOME. Correct?
2) I'll have to change the .vnc/xstartup file to point to the correct file? It points to xinitrc right now.

Thank You.

Yes. Add a command to ~/.vnc/xstartup that will load your chosen X application.
