My laptop is happily displaying on my monitor (through a KVM) here at the office. Perhaps there is a GPS device that disables the external video port when I am more than 10 miles from the office. Hopefully, I will find a better explanation.
Much thanks to Bill Sconce for being there to set up a VNC connection and allowing me to drive from his laptop. Let me provide some URLs in a clickable form for any folks who are interested: http://iptables-tutorial.frozentux.net/iptables-tutorial.html iptables is the IP packet processor that provides a stateful firewall in Linux. This page covers much more than just iptables. It provides detailed IP protocol explanations. http://freshmeat.net/articles/view/1433/ Short example of using bridging and ebtables to control traffic on the ethernet frame level. Another case of controlling local packets without regard to the IP addressing. http://wiki.openwrt.org/ Documentation part of the openwrt web site. http://wiki.openwrt.org/OpenWrtDocs/NetworkInterfaces Contains the block diagrams to show internal operations. In pushing things around just now, the external monitor went blank. It's a hardware problem! My cable here is pretty stiff so it normally provides some upward pressure on the external video connector. With no pressure, the screen goes blank. -- Lloyd Kvam Venix Corp. 1 Court Street, Suite 378 Lebanon, NH 03766-1358 voice: 603-653-8139 fax: 320-210-3409 _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
