You need to have your ISP add 'www.alisa.org' to the DNS entry for 'alisa.og' on their name server, right now only your ISP is queried for information about hosts in your domain. Or you could run a nameserver on your machine and ask that your ISP change the Internic entry so your system is the primary nameserver for your domain, > 2) I'm interested in providing web pages to customers on the machine and > some want their on domainname.

The 'cheap' way to do this is to just have the other domains resolve to your IP address, and use url's of the form: http://www.company1.com/company1 http://www.company2.com/company2 The drawback is that under the current HTTP protocol, there is _no_ way for the server to serve a different page for each company without that extra "/companyX" on the end of the URL, except for the current Netscape versions. This also means that the URL: http://www.company1.com/company2 Will bring up the pages for company2! Not exactly a desirable effect. The 'real' way to do virtual hosting is is with IP aliasing- adding an additional IP address for each unique domain name, but it is very unlikely that your ISP will cooperate by giving you many more addresses just so you can compete with their service... FreeBSD (and NetBSD,Linux, WinNT) supports IP aliasing, and can handle several dozen addresses easily. -- David Richards Ripco, since Nineteen-Eighty-Three My opinions are my own, Public Access in Chicago But they are available for rental Shell/SLIP/PPP/UUCP/ISDN/Leased dr@ripco.com (312) 665-0065 !Free Usenet/E-Mail!
