The solution which you have provided is working
with internal IP's(LAN ) but not with external IP's. I am able to
connect with echoVNC to directly connect with LAN address like
192.168.0.1 or 192.168.0.2. But when i use some static
IP's for the same network where the above systems reside it is giving me
UltraVNC unknown Authentication Scheme error. I have no-ip.info installed
on these computers. Is this causing any problem here.
This is the detailed explanation of what i am doing
:
1. Host with
HOST1.no-ip.info and the echoVNC installed and i am able to see this
connected to echoserver. It is a Windows XP pro machine.
2. At my system (viewer side) installed
echoVNC and connected to the same echoserver where the host is connected
to.
3. From my system (viewer side)
through internet using echoVNC i am trying to connect by using "connect via
echoserver" to Host1.no-ip.info.
a.
I have changed the default veiwer of EchoVNC viewer to UltraVNC viewer, so it is
opening up UltraVNC viewer
b. Shows
"connecting ...."
c.
Password requested.
d. and ending
up with a messagebox "Unknown Authentication Scheme
!"
What's wrong here ?
