Squeak VNC
Locked
 
|
vncviewer localhost:1 or vncviewer 192.168.1.101:1 ...and up comes the virtual screen. Fine, that’s great. But when I try to access it remotely from another computer, say, another Linux box: vncviewer 192.168.1.101:1 or a Windows machine using TightVNC and address “192.168.1.101:1”, I get absolutely nothing coming up on the Linux box after I’ve entered the VNC password, not even an error message, and on the Windows machine, I get the error message “error while waiting for server message”. What am I missing here? Thanks.

Yes, you are correct. All my machines are on the same segment. I only have
one router. However, I want to eventually access the Squeak image over the Internet. Regards, Richard On 12/4/07 10:08 AM, "Randal L.

You'll need to either open the VNC on a routable address then, or establish some sort of tunnel. The problem is the same whether it's VNC or not, so there's plenty of literature on that. I suggest googling for "tunnel ssh" and looking at the lead hits. -- Randal L.

For security reasons I would not open those ports to the outside world
but ssh into your box with a port forward. This will likely also solve your problem. Adrian On Dec 4, 2007, at 16:21 , Richard Eng wrote: > Yes, you are correct.

I created the SSH connection. I had previously done that in order to run VNC
against the Ubuntu desktop. It had worked fine. So following your suggestion, I made the SSH connection and tried to connect to the Squeak image. I got the same "error while waiting for server message" error. I think we're all missing *something* here... Richard On 12/4/07 10:24 AM, "Randal L.

:1 refers to port 5901, :2 => 5902, :3 => 5903 ...

Yes, I did set up the tunnel. Otherwise, I wouldn't have been able to do VNC
previously to the Linux desktop. Richard On 12/4/07 11:19 AM, "Randal L.

This was the only one which worked without any problems. regards, Norbert _______________________________________________ seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Latest update...
When I try 'vncviewer 192.168.1.101:1', the connection is reset (fails). Interestingly, on the server where the Squeak image is running, the following printout appears in the Transcript: RFB: caught MessageNotUnderstood: LargePositiveInteger>>hex I don't know much about Smalltalk but this suggests to me that the VNC Squeak code isn't quite up-to-date. :-) Anyway, I can't be bothered to debug VNC, so I'm going to give up on using it.

I've tried playing with the encoding settings. I made both vncviewer and
RFBServer use ZRLE encoding. The connection continues to crap out. In fact, sometimes it causes the entire Squeak image to freeze! This is ridiculous. Squeak VNC shouldn't be this difficult. (It's also ridiculous that vncviewer supports a variety of encoding schemes and Squeak VNC ***only*** supports ZRLE. And ZRLE, btw, is not available in the free version of TightVNC for Windows. What a bummer.) If a tool is this problematic to use, then you know it's time to give up on it...
