I must mean 8.6. I think I am confusing it with 8.5.1.... It has been 16 years..... 8.5.1 and 8.6 were the greatest, though...<p>Anyway, the great thing about hosting on Classic Mac OS is that there was nothing to exploit. With no remote admin capabilities beyond some Appletalk-related stuff, even if someone did find a way to compromise your system, the only thing they could really do was freeze it.  I threw a Mac OS 7.5-ish (obviously I am forgetting numebrs) Mac up on the Defcon LAN and put the IP on the whiteboard for targets, and not a damn thing happened. Not even a hang...
