Problems with SC setup

winstoncpr · Post by **winstoncpr** » 2005-11-02 21:24

I'm fairly new with the SC setup, I've browsed the forum and didn't find any answers so I thought I post the problem and see if someone could help me.

I've followed the guides for creating my SC executable. I'm running on a test environment with the following info.

These IP's have been changed for privacy

support workstation IP: 192.168.0.2

SC Server IP: 192.168.0.3

I open the VNC in listen mode with the following command on the support machine:
"C:\Program Files\UltraVNC\vncviewer.exe" -listen 5500 (command from shortcut)

Then I double click the SC executable on the host machine. I get a popup box stating establishing connection, 5 min try period.

I never get a connection established, eventually the SC executable ends and disappears.

Both machines are Windows XP, with port 5500 and 5900 TCP opened on the SP2 firewall.

Here's my helpdesk.txt:

What am I doing wrong with the setup? It seems pretty straight forward, but I must be overlooking something.

winstoncpr,

well it depends on how your network is setup. Are there firewalls between the SC and the Viewer???

If so you may have to forward 5500 to your Ip of your viewer.

I see that you have the also have the msrc plugin enabled via your helpdesk file. That connection will not work unless setup the msrc4 plugs are active and configured properly.. For the time being stick with the keep it as simple as possible idea. Dont worry about the encryption connection for the time being. (your second host with the -plugin in front)

Did you try to have your viewer in listening mode when you launched the SC.exe?? Without a repeater it will have nothing to conect to so that maybe an issue or not??

Do you have any kinds of other limitations on the network you are testing this on? I know that some networks are really tight and block everything and only allow certain protocals and ports to be active maybe you have something like that going on?

Viewer Command line if you need it (default directory, default port)

"C:\Program Files\UltraVNC\vncviewer.exe" -listen::5500

well actually for the 5500 you should be able to just use the -listen because it is the default port

Single Click is a reverse connection so the computer that you are running the created exe file on is the server and your workstation is the viewer.

One pc sends data (server) PC two recieves images (veiwer)

Well I hope this helps you some,

Take Care,

Bevtech,

Both computers are on the same switch and same subnet.

I don't have the encryption plugin configured on either machine, although I do have it configured in the helpdesk.txt. I just took the default configuration and used that with the slight mods that are shown in my previous post.

I've tried starting the viewer before the server and vise versa. I've never been able to have any luck with getting a connection.

I don't have a repeater configured, I didn't figure I needed it since I'm working on the same subnet/switch on both machines.

If that's the case what's the configuration for the repeater?

Our firewall shouldn't be an issue as we allow any traffic inside without restrictions.

From my understanding of SC I should be able to open the viewer and send/direct the customer to the SC.exe and have them execute it to open a remote view on thier system

I've been a longtime user of UVNC and the features of SC would be invaluable to increasing security and support reach for my users

Correct Your viewer.exe can view the remote (SC) server if the settings are correct. I looked at the helpdesk.txt and I didnt see anything wrong off of the bat.

Now, when you launch the SC exe you created does it prompt for access from windows firewall??

You really don't need a repeater if you are using it in a subnet or even a WAN if you have it configured properly.. I do because it is easier for me but it will work without one.

What errors are you getting??

No errors are showing up on the server, it just says establishing a connection then it times out after 5 minutes or so.

No prompts from SP2 firewall, because I opened port 5500 and 5900.

I have UVNC loaded on the test machine, but it is currently disabled. so it won't run.

OK try this click on here to test, It will show you what you must type in to test.

Use at own risk.

Winstoncpr,

There has to be a syntax error or something simple causing your problem.

A stand alone viewer should work for viewing the Single click connection.

You are using defaults settings and made no changes.

You are a long time user of VNC hmmmm.

So you understand how VNC works.

You are not even using ID numbers.

and you are using on of the most basic configurations that should work.

How are you creating your SC.exe file??

What version of SC are you using??

I mostly create from the ultravnc website.

I am out of ideas. Dwalf idea is a good one:D

It is just puzzling me and it should work for you..
