So somebody does read my blathering. Terje Bless <email@example.com> pointed out the Internet host names are case-insensitive. Not everything is the Internet, but maybe it is time to re-examine this for LANs. I tried my home LAN and on the SuSE 6.1 Linux box - ping and nmap don't care about the case. Same for the RedHat 6.1 Linux and Solaris 7 boxes at work. I'll see if I can con one of the Windows NT users to check it out. Same for the Windows 95 and 98 boxes at home when I can reach the power switches.
Now I wonder what system I was using when I concluded that hostnames are case sensitive. Probably not something in the personal computer world.
Maybe time for an old dog to learn some new tricks.
