remote Desktop connection Setup

English Applications
1

Hi, I have 2 OpenSUSE 10.3 PCs.

Both are on the same IP subnet XXX.YYY.NNN
Both can, in a terminal window, log in into
each other via ssh in command line

I try Remote Desktop connection
from XXX.YYY.NNN.135 to XXX.YYY.NNN.151
on “151” I us Desktop Sharing and create a
personal invitation
Host: XXX.YYY.NNN.151:5900
Password: …
Expir. time …

On “135” I use Remote Desktop Connection and
enter in the vpn field: XXX.YYY.NNN.151:5900
and select ‘High quality’ (both on same LAN)

Then nothing happens: no ask for a password
after 1 minute, a window “Server not found”

What can be wrong???

Hi, it could be a firewall problem

Indeed, on the target machine firewall was enabled, with only SSH allowed.
I could have tried with allowing
VNC
VNC server
(I think on the receiving machine it should be VNC server, what is VNC then (for the client only?)

Anyway, I first tried disabling the firewall alltogether on the receiving machine.

Still no connection (no window asking password) only, the window “Server not found” now appears almost immediatly instead of after 1 minute.

Any clues?

Still no result, except that

Hi,

Is your router blocking any VNC communication ports?

Also, have you enabled VNC in the YaST2 module?

(If you don’t have the YaST2 vnc module installed then you can install it using the Software Management module.)

5

The network cables of both openSUSE 10.3 PCs are on a same 8-port switch…

I now allowed in Yast, VNC remote desktop administration (I believe this did not exist
and was not needed in SuSE 9… can’t remember)

Still, no results.
Now the window ‘Server not found’ again takes
very long to appear (still not appeared yet…)

Hi
What happens if you try telnet as a test?


telnet <ip_address> 5900

Do you get a connection prompt?

What DE are you using, if KDE have you tried krdc?

Hi,
I forgot to notice the window on the VNC server where I had to allow the connection :slight_smile:
There is now connection, but not very usefull:

  • it is way too slow :frowning: (and that for 2 systems sharing a same 8-port switch)
  • the mouse pointer is not visible in the window displaying the servers desktop :frowning:

I use Windows Remote Desktop connection from home to view the Display of a Windows Server, and this is without any problems and almost of equal speed.

Is there a way to use Windows Remote Desktop to get the display of an OpenSUSE 10.3 server? Might this be faster and without mouse pointer problems?

Hi
Sounds like your network is busy… broadcast traffic? have you had a
look via tcpdump/wireshark?
I prefer using NX from nomachine as it uses ssh, server is free for
linux machines and there is a windows client. The OSS version is FreeNX.

I too have found krdc to be very slow and the display is terrible between two OpenSuse 11.0 PC’s. I use VNC server on my Centos server box, which I access from one of the Opensuse 11.0 PC’s ( remote desktop, vnc option) and it works great.
I also access the server from windows with NX client, running free NX server on Centos box. This also works great. ( runs through ssh, which gets throughe the firewall at work, he he)
Is there a trick to setting up kdrc? There’s not many options.

x11vnc works pretty good

HOWTO: Setup x11vnc as krfb alternative.

I was able the use

> vncviewer

…in OpenSuSE 11.1 to access the windows desktop on a windows box (using UltraVNC server on the windows machine) from behind a router (out across the internet), but I had to have the OpenSuSE firewall turned off. vncviewer (on OpenSuSE) is way faster and more stable at controlling a windows UltraVNC server than using UltraVNC viewer on a second windows machine.

My problem is that now I need to get a KDE (non-root) session on my suse box from a windows machine - and I need to use SSH to make the connection. The way folks at my work said to do this was with “putty” on the windows box, but the port mapping stuff is hard to figure out…
