dns wont work

dilberim82 · 11-25-2001, 01:48 AM

hey,
I just configured dns & bind and i think they work fine. I have a problem though when i go to http://ns.mydomain.com it gives me the homepage, but when i go to http://mydomain.com, it gives me a dns error. Do you guys have any idea why it would do this? And it wont give me the homepage when i go to www.ns.mydomain.com whats the difference between http://ns.mydomain.com and http://www.ns.mydomain.com? Pinging, nslookup, and dig works fine with ns.mydomain.com but it does not work with mydomain.com

In order to get www.ns.mydomain.com working you will need to add an entry in your zone file for mydomain.com - try 'www.ns.mydomain.com IN A xxx.xxx.xxx.xxx (the ip address of ns1.mydomain.com)

For brevity you may want to re-examine your name server setup so that you can have ns.mydomain.com, www.mydomain.com (instead of www.ns.mydomain.com) all pointing to the same IP. For an intranet you can also add a CNAME entry like 'www' or 'home' so that users can just type in http://home in their browsers to see the main page for your network.

you should have it set to look on local net first

resolv.conf

order hosts, bind
nameserver www.xxx.yyy.zzz
nameserver aaa.bbb.ccc.ddd

this will search the hosts file first

then put it in the hosts file like this

ipaddress name name.domain nickname

10.0.0.1 Alpha Alpha.home Alpha

Thanks for replies guys i tried both but it still does the same thing.
I just checked everything over again and everything seems ok but i am including the contents of resolv.conf. if i take anything everything after search, i cannot connect to internet so in that case nothing works. After i put it in and try to nslookup it gives me this message:
Server: 24.93.1.119
Address: 24.93.1.119#53

Non-Authoratative answer:
Server: ns.mydomain.com
Address: IP address of my domain

resolv.conf
order hosts, bind
nameserver myipaddress
nameserver ns.mydomain.com
search rochester.rr.com rr.com
nameserver 24.93.1.119

and when i check nslookup ns.mydomain.com myip it does not connect to my computer. Thanks alot for any replies.

What do your zone files look like for that domain?

dilberim82 · 11-27-2001, 11:44 AM

I am not home right now but i'll post it here tonight. Thanks alot but in the meantime do i have to change the permissions of the zone files?

mcleodnine · 11-27-2001, 12:15 PM

Nope - you shouldn't have to mess with the zone files' permissions - if you had a problem there it would show up in the syslog messages. (You are checking the logs for proper bind startup, right???)

dilberim82 · 11-28-2001, 06:18 PM

Ok myhostname is the hostname of my computer and domain.cxm is the domain name i am trying have as the nameserver. Example.com is another domain name which has nothing to do with my nameserver. I just put it there to check if my nameserver works but it obviously does not. The name of the file is on the top and what is in it is below the # sign. Thanks alot everyone especially mcleod. I did not include named.ca but i can if you need to see the contents of it

. And the ip numbers and everything else is made up.

Anybody have any idea?

mcleodnine · 11-30-2001, 09:27 PM

It looks like you're abusing the shortcuts...

Your zone file(s) can start with the '@' to abbreviate the name that called it, but you can't use that same zone name in the 'A' records where the hostname should be. Your logs probably are complaining about www.domainname.cxm.domainname.com as you have not terminated the hostname part of the 'A' record with a dot "." The first field of an A record is the hostname + the domainname. For brevity BIND lets you use the hostname only (without the trailing dot) and it will add the domainname to it. If you want to use the fully-qualified domainname you need to terminate that part of the statement with the dot

Code:

hostname.mydomain.com.   IN  A xxx.xxx.xxx.xxx

is the same as

Code:

hostname   IN  A xxx.xxx.xxx.xxx

Please post some log data as it's easier for me to work backwards (and it gives me a chance to go out for a pint or two).

Your IN-ADDR recors are also wrong. The IP to name mapping may also be shortened by including only the last three digits without the trailing dot or by using the whole ip address. When you used "1" it assumes that the IP addr should resolve to 25.35.158.1 rather than 25.35.158.198

Here's the format I use and it's served me well;

Code:

                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
