The Raq is behind a firewall (which could be the problem but thought I better get a handle on DNS first). The email/web raq is on the DMZ of the firewall. I've registered a test domain name of www.nomecity.org with www.register.com before I switch over our 'real' domain from a local ISP. We are using a cable modem for our internet. I named the server host[www] domain [nomecity.org].

www.nomecity.org	CNAME	nomecity.org

You want www.nomecity.org to be an A record not a CNAME.

nomecity.org	MX	10  mail.nomecity.org

mail.nomecity.org	CNAME	nomecity.org
Ditto with mail.nomecity.org instead of a CNAME.


Dan,

First, I really appreciate you taking the time to look at this and offer help. Thanks!!

When I use www.dnsreport.com, it says "no CNAMES for domain" and since I've been on the list awhile here I've noticed lots of warning not to use CNAMES so I've avoided them, or I thought I have. How did you deterrmine that there were CNAMEs involved? When setting this up, I followed the instructions per the Cobalt raq4r manual on pages 190-194, using the add A records and add MX records selections.


My guess is your cable provider doesn't allow a server on their network
as well and may block some of the ports you want to use. But,
considering their Terms & Conditions link is broken and they still have
a Y2K Statement link on the site, I doubt they're paying attention.


They allow servers, even for home users, supposedly. I've made my attentions known to them from the start, and hence the static IP we're paying extra for. But I'm not saying that there may not be problems there.


Well, 24.237.254.24 isn't responding now.


Dang. There have been some down times in the past but not sure what's going on with that now. I can ping it but not sure how to test it further from inside the network.

I just see that Paul W. has given me a great looking cookbook type of instruction to go through. Maybe the answer is in there. I must reiterate that I only know enough to really muck things up so don't assume any better of me. (I am reading as much as time allows on all this admin/linux stuff.)

Cheers, Jim D.
