Rob's question is actually a sub-problem of the more global problem. Bootstrapping Austin into a workable entity. Consider: Site A open-forge.org Fractional T1 DNS (16 IP's) mail auth cpu file Site B ssz.com ISDN to Site A DNS (share IPs' w/ open-forge) mail auth cpu file Site C (no domain) DHCP auth cpu file Problem: We want each site to have a sinlge machine handle the authorization for that domain. It should also handle access by members of the 'h18' domain (which is virtual in the sense that it's not tied to any IP or domain). open-forge and ssz each run their own DNS (or share a single one, usually at open-forge). Site C however is dhcp with no permanent IP's. This is a problem for auth services I suspect, they need some sort of IP/name connection. Which is the reason that I suggested to Rob that he shold create a DNS domain of .rob and configure his machines. -- ____________________________________________________________________ We are all interested in the future for that is where you and I are going to spend the rest of our lives.
