setting server rfb port to non-default - on the vncviewer
I needed to do this recently. I found the -rfbport option on the vncserver but no comparable option on the vncviewer, which left me unable to connect to the Xvnc.I have made a set of three small patches to vncviewer to add a new -ServerPort parameter on the command-line if anyone is interested. Or did I miss something already available? John ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
Re: Cannot connect from work
so accept conections should be 5900 which is the default, and I put 5900 on the source port on putty, but in sessions category the port number should be say 22 so It goes through the firewall at work through port 22, and comunicates with the vnc server on it's default 5900, am I right? I think I can get it working now. I just got confused when he said to put 5904 when his router accept on port 4. But when I tried the "accept connections" on port 22, I tired just to make sure, and connected with a black screen. It's weird because then it closed and said "Connection reset by peer". Should ssh tunneling fix or prevent this since I wasn't using ssh when I tried this. I'm really sorry for bothering you with this. -Original Message- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: vnc-list@realvnc.com Sent: Mon, 9 Oct 2006 6:35 AM Subject: Re: Cannot connect from work On Sunday 08 October 2006 07:25 pm, you wrote: > The instructions on that ssh putty link you emailed to me didn't work.

I'm not running vnc on Windows at this time, so I don't recall what the setting is called, exactly.

Re: New to VNC List...
This came up at least 100 times. You are running VNC version 4.1.1 or earlier which had a security problem allowing attacker to login without a password. The update was posted few days after the problem was discovered but it seems that no one bothers to update. You need to redeploy the latest version of VNC and do whatever other procedures are required in your company after break in has been detected. IMHO, running free vnc software exposed to the Internet is not very smart thing to do to begin with. Regards, Alex Craig Musgrove wrote: Evening...

Re: some problems with vista
Do you have an idea about problems of VNC with Windows vista ultimate edition ? I try to connect but often is : no connection or connection reset by peer (10054) Always the windows go down when I try to make some administrative operation Thanks Vista has separate admin restrictions on the Internet connection and it's default set to limited (at least in the version I have tried). This would deny you any changes that requires administrative functions. I recommend looking at your connection setting which should let you raise your administrative rights which should be possible using your version. I've been interested in this feature for sometime and I'm glad is works. ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list

VNC Connection Spontaneously Dropped
Problem: I just recently had a VNC session drop without warning in the middle of an X session on a RHEL 4 server. Since the session was initiated on the server via xinetd, the disconnect aborted the entire X session. The server is running vnc-4.1.2-1, while the client was vnc-4.1.1-10.1. Questions: 1. What might cause a session to drop without warning like this, assuming network connectivity remains constant and there was no explicit action to terminate? 2. How can I setup logs on server and/or client to record vnc messages and activity? Background: I have never had this happen on a VNC connection to the native console (0:) display, but I can recall one or two occasions in the past where sessions dropped on xinetd connections. I have already upgrade the client to vnc-4.1.2-1 in case the disparity in versions contributed to the event.

In terms of authenticating across a protected intranet LAN, would you say this is is at least as secure a method as default MS Windows password authentication? --Cal Webster ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
