Can´t connect to vncserver using vncviwer neither with http

Post by betoco »

Hello,

I´ll appreciate your help with the following problem:

I want to vncviewer to connect from my Office´s PC to my home´s PC.

The PC in my home is configured with XP+SP2, has installed uvnc 1.0.4 RC13 and it is behind a router D-Link DI-524. In this router I configured the "Virtual server" option in order to forward the ports 5800 y 5900 as follow:

Advance--->virtual server
Name : accesovpn
Private IP : 192.168.0.137
Protocol type: Both (udp/tcp)
Private Port : 5800-5900
Public Port : 5800-5900
Shedule : always

Also in this PC, i installed "Dyndns updater" and created a host name "colocolo.dyndns.org". I can execute ping to colocolo.dyndns.org from internet succefully.

For other hand, the PC in my office is running XP+SP3, IE 7 and I just to installed Java from the Sun page. Also I installed uvnc 1.0.4. This PC is also working through a router but in this router (office router D-LB604) no configuration has being done.

Problems:

1.- When I executed from my office vncviewer (colocolo.dyndns.org:5900)to connect the PC in my home, the following message appears:

"You´ve forgotten to select a DSMPlugin and the server uses a DSMPlugin"

At the execution time I chose "MSRC4Plugin-122.dsm" and generate the key using config bottom.


2.- When I use under IE 7 "http://colocolo.dyndns.org:5800" appears java logo but after a few seconds the screen remains in white color.

Could you help to find which is the problem?

Regards

I wanto to add some details in order to have more information.

Fom the Office PC i executed a telnet over 2 port (5800/5900) and the output is:

c:\ telnet colocolo.dyndns.org 5900
RFB 003.006

c:\ telnet colocolo.dyndns.org 5900
No errors appears


Also, if I remove (unclick dsm option) from the uvncserver properties (Home PC) both http and uvnviewer in work fine from the Office PC.

Aparently the problem in may case is related to dsm plugin.

your right the problem is with the plugin but only because the way you set it up...

the DSM plugin must be the same (same version and same name) on both server and viewer sides and if your selecting to use DSM plugin on Server side the viewer must also use it.

the same applies for the rc4.key

the Java viwere will not connect using encryption e.g. the dsm plugin is encryption so if it is set on server side client java will not connect.

if you use vnc over VPN (virtual private network) you won't need dsmplugin encryption.

Thanks all for the help, my connection is already working and can also transfer files succefuly.

Now the only problem that I have is related to the configuration of the display. When I connect from my office using vcnviewer or http to the vncserver in my home the display is not being correctly displayed, like a shadow appears around the images on screen. If I use option "Restricted color" in 64 or 256, like a shadow appears, if I use option "full", the screen begin to blink.

In my home the "display properties" configuration is, color the highest (32bits) and the resolution is 1024 x 768 pixels.

Could you indicate what could be wrong in the configuration of my vnc?

vnc server
disable alpha-blending, so it remove blinking of mouse cursor.

side effect
you could not see some pop-up message known as alpha-blending

like layer of CAD software, you could see 1st layer but not others.

Hello, thanks but this option is already disabled on vnc sever.

Related to this problem, i want to say you that now this problem is only happening when I use IE7 (with java installed) to connect to the vncserver and the other problem is that i don´t have the option "auto scaling" when i use IE7.

Using vncviewer, when I "clicked" refresh bottom, the image appeared fine, doing the same in IE7 doesn´t work and the image continue appearing bad specifically when i try to watch .jpg files.

Hello,

I have a Intel Pentium IV and the SP3 is already installed, the only problems that I have now related to the configuration of the vncviewer and vncserver are:

1) I don´t have the option to "Auto Scaling" under IE7 ("auto scaling" option is present in vncviewer) and 2) image are not display correcltly using IE7, specially .jpg files and files related to images.
