Happy New Year and Greetings, I have spent a couple weeks monitoring posts and searching for help in FAQ's and archives, as well as other related websites. I don't want to waste anyone's time with something already covered. After narrowing many issues down, thanks to the help of the archives and daily posts, I have one remaining problem.
I am using RealVNC Server 4 (service mode) on Windows 2000 Professional SP4. I have installed Cygwin as an SSH service on this box. I set RealVNC Server access control options to 'only accept connections from local machine', but I cannot access the RealVNC server on the machine using PuTTY .56 SSH client from my Windows XP Pro laptop. The XP firewall is disabled. I am running Zone Alarm Pro on both client and server machines. RealVNC and SSH/SSHD have been given appropriate access on both machines. My SSH client connects and authenticates successfully. But when I try to connect with RealVNC viewer to 127.0.0.1, I get the message 'VNC Viewer : Error - server closed connection unexpectedly'. There is nothing in the application event logs relating to this error. There are events showing connection and authentication with sshd but nothing for WinVNC4 unless I take SSH out of the equation. I think the RealVNC server isn't even getting the connection attempt. Maybe I have missed a step in configuration of SSH. RealVNC works flawlessly between the 2 machines before adding SSH into the picture. The only way I can connect to the server using SSH is if I disable the 'only accept connections from local machine' and add the IP address 127.0.0.1 to the access control list on the RealVNC server. This of course makes using the SSH tunnel pointless, since the tunnel is not required to connect. But, it does however connect. Shutting down Zone Alarm Pro on the server gives the same results. This is all taking place from inside my local network. I am behind a Linksys router with port forwarding enabled for TCP ports 22 (SSH), 5800 & 5900 (RealVNC) to my server's IP address. I can also get the same results from outside my local network, so at least my port forwarding seems fully successful. Thanks in advance for any assistance you can provide.
