Hi, I realize BIND and DNS can be difficult, so I am asking the forum to help me out on this one... I'm on Fedora Core 4 Linux Here is what I have done so far: 1. Main IP, 188.8.131.52 is setup in ISPconfig and ifcfgeth0 2. This IP is a nameserver, with domain: www.mymaindomain.com , for example I use ns1.mymaindomain.com for domain installation on this specific IP, which is the "admin" or root user. 3. Second IP, 184.108.40.206 is setup in ISPconfig and aliased as ifcfgeth0:0. 4. This IP is a nameserver, with domain: www.mymaindomain.com (same domain as above), for example using ns2.mymaindomain.com. 5. All my other IPS, 220.127.116.11-15 have been added to ISPconfig and each one has an alias in ifcfg as ifcfgeth0:0, ifcfgeth0:1, :2 :3 ....etc 6. I can Ping each IP successfully, including the ones without nameservers. 7. I went to ISPConfig and made a few new resellers and clients. I then added the main reseller site as starting point, for example: Reseller 1 - Client Smith - Site: www.reseller1.com . I then created several additional websites under this reseller and client. I assigned www.reseller1.com domain and the other domains the same IP in ISPconfig. 8. Here is where I have lost my way: Now, I want to setup Reseller 1 with its own nameserver, ie. ns1.reseller1.com using the main reseller domain, www.reseller1.com. 9. So, I went to the ISPconfig entry for www.reseller1.com and added an "A" record for "ns1", keeping in mind that the main entry, "www" has already been added by ISPconfig. 10. Finally, I went to the DNS manager and assigned www.reseller1.com two nameservers: ns1.reseller1.com , and ns2.mymaindomain.com - the second nameserver of the main "admin" domain on the server. 11. Then, I went to my registrar and for the domain www.reseller1.com I added ns1.reseller1.com as the first nameserver with IP 18.104.22.168 and ns2.mymaindomain.com . 12. I repeated these steps for a few other resellers. Now BIND has crashed! When I attempt to reboot NAMED, I get the following error for almost all the domains and reseller main domains I installed: Code: Starting named: Error in named configuration: zone 0.0.127.in-addr.arpa/IN: loaded serial 1997022700 zone 124.151.64.in-addr.arpa/IN: loaded serial 2006091302 zone 120.151.64.in-addr.arpa/IN: loaded serial 2006091301 zone 2.96.208.in-addr.arpa/IN: loaded serial 2006091302 zone mymaindomain.com/IN: loaded serial 2006081603 ##...other reseller domains withsame result as my main domain... ##.. and then a long list of the following errors: zone reseller1.com /IN: loading master file pri.reseller1.com : not a valid number _default/reseller1.com/IN: not a valid number zone reseller1site1.com /IN: loading master file pri.reseller1site1.com : not a valid number _default/reseller1site1.com/IN: not a valid number Any thoughts? I am completely baffled... Is there a tutorial for setting up private nameservers for each reseller main domain, and then adding additional domains under the reseller with the reseller's private nameservers??? Thanks in advance for your help!
