I had to reinstall RedHat 2 days ago. Now VNC is not working. I wanted to work from my windows desktop to work on linux system.

Initially i had a problem with getting the GUI, but i edited the Xstartup file to get that working. Now, the problem is that i can't even connect to the terminal.. From other machine... the error i get is host not found... i can ping the IP on linux machine but when enter that in VNC viewer on other machine i.e. 10.0.1.11:1 ... It doesn't work.

here is my log in .vnc folder

***********************

If you need, here is the text of my xstartup in .vnc folder

#!/bin/sh

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &

Try this for your xstartup:

#!/bin/sh

# Red Hat Linux VNC session startup script
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

Thanks so much for the help
Now, my log file looks like this
VNC still not working...

sorry but not sure what else to say.
that is what i have on my redhat box.

I don't see the VNC service there on the "Services" in System tools-->server apps

When it was working it used to be there..

However, I do get the .pid file when i type vncserver on the terminal...

Please let me know if you can narrow it down.. Just tell me what could be and wat CANNOT be the issue, so i don't spend time on configurations that won't help.

the process should be called xvnc
make sure you don't have a firewall blocking it

i would uninstall the rpm and install it from source

I went to System Settings-->Server Settings-->Services and couldn't find xvnc... I remember seeing VNC when it used to work,

Hey, can you tell me how to uninstall the rpm and install from source.

I went to the system logs-->Installed RPMS, i saw
vnc-4.0-1.beta4.11.i386.rpm

I think i was using the vnc 3.3.6 before... i want to try uninstalling vnc4.0 and install vnc 3.3.6. i am gonna look for how to do it..
you can tell me if you have time.

Thankyou so much

It was the firewall... Got it
