Im back everyone.

I'm in the process of setting up a DNS server on our network. I have decided to go with DJBDNS for a lot of reasons. Mainly, its security.

My question though is what DNS software do you use and why?
What do you dislike and like?

Just thought i'd try and start a long thread, again. :)

Anyone here use djbdns?

Playing with it right now...seems pretty nice. I like the security features, modularity as well as the fact it is not a resource hog.

Just for kicks, what is everyones personal preference for a DNS server?

I've only had exprienece with the standard Bind DNS server. Worked well on my old Sparc 20. Had a rough time configing it on my OBSD box at work tho. Perhaps I should read the manual.... :twisted:

Im back everyone!! Have a question about setting up a particular DNS record, specifically about MX.

I wanted to test my mail gateway and internal mail server before I make it live. I figure the best way I can do this is to create a second type of MX record to do the testing.

As it stands now, if you do a dig on our domain, you will see something like this:

[code:1:9c8f685830]; courtesymortgage.com domain lookup file
$TTL 43200
@ 43200 IN SOA ns1.aspadmin.com. domain_control.courtesymortgage.com. (
1064506332 ; serial number
43200 ; refresh every 12 hours
7200 ; retry after 2 hours
1209600 ; expire after 2 weeks
43200) ; default ttl
;

@ 43200 IN A 209.x.x.x
@ 43200 IN MX 10 www.courtesymortgage.com.
@ 43200 IN NS ns1.aspadmin.com.
@ 43200 IN NS ns2.aspadmin.com.
@ 43200 IN NS ns3.aspadmin.com.
blowfish.courtesymortgage.com 43200 IN MX 10 blowfish.courtesymortgage.com.
blowfish 43200 IN A 216.x.x.x
db 43200 IN A 216.98.128.79
ftp 43200 IN CNAME www.courtesymortgage.com.
localhost 43200 IN A 127.0.0.1
mail 43200 IN CNAME www.courtesymortgage.com.
news 43200 IN CNAME news.ispadmin.com.
pop 43200 IN CNAME www.courtesymortgage.com.
smtp 43200 IN CNAME smtp.ispadmin.com.
support 43200 IN A 216.98.128.98
webmail 43200 IN A 216.98.128.34
www 43200 IN A 216.x.x.x[/code:1:9c8f685830]

Ok...I added the entries for blowfish. Blowfish is actually my mail gateway server. I wanted to send some test emails to the domain: <user>@blowfish.courtesymortgage.com

The reason for this setup is i want to fully test and make sure my setup is working correctly, BEFORE I switch everything over. I want to make sure all my tracks are covered.

But, my question is, does my record look correct? I'm not sure if it is correct or not, so I thought i'd ask. :)

Thanks guys.

Im been doing some research on this this morning.

If I wanted to have a MX record for blowfish.courtesymortgage.com, should it look something like this:

[code:1:5de3d89e62]blowfish 43200 IN MX 10 courtesymortgage.com[/code:1:5de3d89e62]

or

[code:1:5de3d89e62]blowfish 43200 IN MX 10 <IP address that will be the MX record?[/code:1:5de3d89e62]

At the same time, I did not want this to interfere with my current MX record for courtesymortgage.com

That make sense?

[frisco]

[code:1:9629b2f60f]blowfish 43200 IN MX 10 courtesymortgage.com[/code:1:9629b2f60f]

Don't forget the trailing .


That make sense?
Yup!

[tarballed]

Yep...i forgot about...that could have been bad.

So to sum up, to get my desired result, I should edit the record to reflect this following:

[code:1:f3ffc6036c]blowfish 43200 IN MX 10 courtesymortgage.com.[/code:1:f3ffc6036c]

I do have an A record set for blowfish (Which would get routed to my mail gateway.)

Just so im clear, this will allow me to send email to the address of:

<user>@blowfish.courtesymortgage.com

and will not interfer with any email for the domain courtesymortgage.com, correct?

Just making sure I have all my ducks in arow. :)

Thanks frisco.
