Do you tightvnc connection closed error wish to reconnect? Cause This is one of the more common error messages reported,

and the error itself does not give an adequate description of the actual problem. However, it is most often caused by
Vnc Connection Closed Gracefully
one of the following: Your "Hosts" filter has been deleted, or mis-configured. The "Hosts" parameter tells VNC Server which IP addresses are allowed to connect to it, and by default it is configured to allow
Vnc The Connection Closed Unexpectedly
all IP addresses. If you've re-configured it, or deleted it, VNC Server will refuse all connections. Your RSA private key is missing. This is a rarer issue, but it does happen. The RSA private key is essentially a "hand-shake" between the VNC Server and VNC Viewer computer. The computers will know each other by RSA private key, and IP address, so that if a malicious user attempts a "man in vnc viewer the connection closed unexpectedly the middle" attack, you'll have some warning. Resolution Open up the VNC Server status, and enter the Configuration. Under the "Expert" tab, find the "Hosts" parameter. By default, it should simply contain a plus symbol "+", which denotes that connections will be accepted from all IP addresses. If the RSA private key has been deleted at either end of the connection, it can cause this problem. The RSA private key is stored in the registry of your computer. The easiest workaround, would be to force the generation of a new key. You can do this by running the folllowing command on the VNC Server computer: vncconfig -service -generatekeys If you are using Windows Authentication to log on to VNC Server, please also check that the Windows Event log is not full. More Information. If none of the above work, please double check the Application Event Log to see if a more detailed error log has been stored, then submit a support request.

When I try to connect to it using ip-address:2, I can connect to it. However when I try to connect it using ip-address:4, I'm getting following message:
The connection closed unexpectedly. Do you wish to attempt to reconnect to ip-address:4. Can anybody please help me to resolve above issue? unix redhat vnc windows-firewall share|improve this question edited Jul 18 at 17:05 asked Aug 5 '13 at 13:21 user1336087 2,84162037 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote A vnc server is running on a certain "display", that is the :0 :1 :2 ... at the end of the connection string. Obviously yours is running on display 2 (which is TCP port 5902). I would assume there is either no vnc display 4 and your viewer software is giving a slightly missleading error message, or there is something other than a vnc server running on display 4. share|improve this answer answered Aug 8 '13 at 22:32 kkeller 1,384159 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
