Single Click won't work for me?

[Heishiro]

Hello everyone.

I really don't know what I am doing wrong here.

I have a Windows 7 Workstation @home that i would like to use as a remote viewer for other computers on demand.

Here are the steps i followed:

1.- I installed on Win7 the UVNC x64
2.- I forwarded the 5500 port from my network to the Win7 Workstation
3.- I tried with Win7 Firewall disabled and also tried with a rule allowing port 5500 in for the vncviewer file.
4.- I ran on Windows 7 the UVNC Viewer "Listen Mode" with NO encryption for test purposes.
5.- I followed the procedure to create a Single Click EXE file.
6.- I took the EXE file (Called support.exe) created on the web page and ftp'ed it to a remote workstation i also own.
7.- I ran wireshark on the remote workstation to see what was being transmitted and where.
8.- I also ran tcpdump (linux) on the firewall @home to see if the connection was being received.
9.- I ran the "support.exe" file on the remote workstation, and i could see wireshark displaying the packets going out, and also tcpdump @home showing them in.
10.- On Windows 7 nothing happens and some minutes later the remote computer won't try anymore.

I tried using the three procedures available on the site to generate the exe files, and none of them worked.

I know it must be something simple that i'm missing or don't know about the process. Can anyone help me on this?

If you run a netstat -a |find/i "5500" on the Win7 station does it show that the port is listening?

If you run the support.exe on the SAME Win7 station does it connect?

Is it correct that tcpdump shows the remote packets entering AND being forwarded to the local IP address of the Win7 station?

Can you try the same connection from a machine within your Win7 station's LAN?

I ran the netstat and the 5500 appears Listening.
I ran the support.exe on the same Win7 and when i run it Win7 asks for provileges, i give them to it and then Win7 asks if the program was installed correctly or if it should try to install it again. So no, i can't connect on the same machine.

The other machine, i don't have remote access right now, so i will try tonight as soon as i get home.

Thanks B

Oh sorry B... I forgot to mention, yes tcpdump -i eth0 port 5500 shows the packets going in from the internet, and tcpdump -i eth1 port 5500 shows the packets being forwarded. Thanks again

You might want to try out Gitso (on Google Code) as a baseline test. It's based on TightVNC, uses the same default listening port on the viewer side, and is nearly plug-and-play. (Don't use it at the same time as UltraVNC SC.)

Hello B.

I tried the other software you told me and did not work either, so i double checked everything and was my mistake. My firewall had the rule to forward port 5500 to my @home PC, BUT there was a rule before for a SIP server that was forwarding ports 5000-5500 inclusive. So i in fact was looking at the packets being forwarded, but to the wrong PC.

As soon as i corrected that, Single Click worked flawlessly.

Occam's Razor... Normally the simplest explanation is the right one. Thanks B.

Great to hear it! In the future you might also try the SCPrompt and ChunkVNC projects, which are based on UltraVNC and might be a little more flexible for your single-click needs.
