I can get VNC installed, and Xfce, but I cannot connect remotely with any viewers. tried many ports and still no go. Was using this tutorial

I am guessing its in the IP tables cat iptables

VNC config

cat /etc/sysconfig/vncservers

The VNCSERVERS variable is a list of display:user pairs.

Uncomment the lines below to start a VNC server on display :2

as my ‘myusername’ (adjust this to your own). You will also

need to set a VNC password; run ‘man vncpasswd’ to see how

to do that.

DO NOT RUN THIS SERVICE if your local area network is

untrusted! For a secure way of using VNC, see this URL:

Use “-nolisten tcp” to prevent X connections to your VNC server via TCP.

Use “-localhost” to prevent remote VNC clients connecting except when

doing so through a secure tunnel. See the “-via” option in the

`man vncviewer’ manual page.

VNCSERVERS=“1:root” VNCSERVERARGS[1]=“-geometry 800x600”

I think I should start with a known working tutorial, then if I have issue I can try to troubleshoot them. You are correct it wasn’t started, I forgot to re-install VNC for the 5th attempt, I need a working LAMP platform more than VNC at the moment so I will wait until someone puts together a working tutorial before trying again.

How about “ps -e | grep vnc” Was there any output when you ran <br> <br><pre> <br>/sbin/service vncserver start <br></pre> <br> <br>It doesn’t sound like the VNC server is started.

Got nothing from the <br>netstat -tulp | grep vnc <br>command. Just returns # <br> <br>I can putty into the unit with the ip/root/passwd without issue. <br>TightVNC viewer times out when trying to connect :5901 <br> <br> <br> <br>
