Beginner VNC User - About to have a baby!
Mon Sep 22 19:21:01 2003
Thanks everyone for your well-wishes on our upcoming baby! It was such a pleasant surprise to have all the warm wishes. It looks like at this point, my wife will get induced on Wednesday, 9/24, but that may change. I'll post an update a couple of days.
As to my issue getting VNC to work -- I think I am close. Steve Palocz and a couple others suggested that I set-up essentially a reverse connection, setting up my VNC Viewer at home in "listen mode", and then to add a new client at work to point to the viewer at home.
The great thing about this solution, is that I would be able to use Windows Scheduler (freeware) to run the command line "c:\...\TightVnc\WinVNC -connect mydyndns.org::5500" every minute or so to attempt set up the connection. That way all I would have to do is launch the viewer in listen mode at home, and within a minute or so my work PC's screen should appear when the Windows Scheduler attempts to make the connection. Using the command line with TightVNC doesn't bring up any error window, and doesn't interfere with any other programs running on my PC, so having the Scheduler run this every minute is almost totally non-intrusive.
Problem is -- I can't find a Macintosh VNC Viewer that has the "listen mode" functionality. I've sent e-mails to a couple of the authors of the viewers I've found, but haven't heard back yet. I even tried running the windows VNC Viewer in listen mode through Virtual PC running Windows 98, and mapped the port to the Virtual machine, but I was not able to establish the connection (probably because Virtual PC's "Virtual Switch" is just too slow).
Anyone know of a mac viewer that has "listen mode"? Or, does anyone know how to get a Unix viewer (which has "listen mode" to work on Mac OS X?
I WAS able to get the connection going the other way -- remote controling my mac at home from my work PC. That confirms that I set up the port forwarding on my home router properly, and that my dyndns.org account (giving me a permanent URL for my dynamic IP address) is also set up correctly.
I'm so close, I can taste it? T-minus 3 days to the baby... anymore help would be greatly appreciated!
