But how to assign them? you can set dhcpd to assign specific ips and hostnames to specific hardware addresses (mac/ethernet address). personally, (this is just me), you should act as an isp, not as someone providing everyone with internal networking. give them a single ethernet drop, have them buy a simple firewall/router box from staples (they're like $50) and let them take care of everything on their end. that way you could limit what connects to your system by mac address of the routers, preventing them from abusing your system. -d +( duncan brown : duncanbrown@xxxxxxxxxxxxxxxxx )+ +( linux "just works" : www.linuxadvocate.net )+ -------------------------------------------------- Understatement of the century: "Hello everybody out there using minix - I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones" - Linus Torvalds, August 1991 --------------------------------------------------
