DNS Debugging

David Rodman — Thu, 18 May 2000 15:42:47 GMT

I'm setting up DNS for a private and unregistered domain... Somehow I have
left off something that specifies the default server...and need some help!
Here are the symptoms:
In the syslog I get the following error every hour:
May 18 11:28:21 jabs-hpl named[492]: NSTATS 958663701 958570100 A=48 PTR=359
May 18 11:28:21 jabs-hpl named[492]: XSTATS 958663701 958570100 RR=0 RNXD=0 RFwdR=0 RDupR=0 RFail=0 RFErr=0 RErr=0 RAXFR=0 RLame=0 ROpts=0 SSysQ=0 SAns=407 SFwdQ=0 SDupQ=0 SErr=0 RQ=407 RIQ=0 RFwdQ=0 RDupQ=0 RTCP=0 SFwdR=0 SFail=0 SFErr=0 SNaAns=364 SNXD=5

A lookup has the following session:

# nslookup
*** Can't find server name for address 204.254.212.51: Server failed
*** Default servers are not available
Using /etc/hosts on: jabs-hpl

> set all
Set options:
noswtrace querytype=A

#Lookups = 2
dns [RRCR] files [RRRR]

Default Name Server:

Default NIS Server:

Default files Server: jabs-hpl
> lserver jabs-hpl
Specifying a server has overridden the switch policy order.
The reset command will reinstate the order specified by the switch policy.
Default Name Server: jabs-hpl.jabs
Address: 204.254.212.51

> jabs-hpl
Name Server: jabs-hpl.jabs
Address: 204.254.212.51

Trying DNS
Name: jabs-hpl.jabs
Address: 204.254.212.51

The resolv.conf looks like this:
domain jabs
nameserver 204.254.212.51 # jabs-hpl

Check out the nsswitch.conf file.

Hi,
What is your Domain name (just jabs) doesn't make any sense.
In resolve.conf file
domain jabs.com.

type sig_named restart and watch error messages on syslog.log on another windows. Send me email of that message if you want to.

You need to provide the DNS Server with the information which defines the NS (whatever it is) as the Primary Master Server for your disconnected Domain.

If you do not declare yourself a DNS Master, then even your own servers will not recognise themselves as DNS Masters. DOn't forget, if you are truely a Disconnect DNS Master, you will not have access to the Internic servers to locate the masters to your domain!!!

Let me know if you need further assistance.

Thanks for all the good input... I believe in RTFM but sometimes
the manual just doesn't tell you all you need.
As an update.... and an answer to some questions.
Yes, I know I will be disconnected from the internet. Yes, I do need to be
running as root server.

Yes I have tried the hosts_to_named function
Yes, I still have a problem... although I can get a slightly different functionality (as follows).
AND My thanks to Albert E. Whale and berlene herren for good clues.
(Mr Whale, your web site email says you are on vacation you slug....)

# nslookup
51.212.254.204.in-addr.arpa
origin = jabs-hpl.jabs
mail addr = root.jabs-hpl.jabs
serial = 1
refresh = 10800 (3 hours)
retry = 3600 (1 hour)
expire = 604800 (7 days)
minimum ttl = 86400 (1 day)

David,

If I was on Vacation I wouldn't be sending you any E-Mails.

I'm out of Town, available via E-Mail, just not as fast as usual.

I seem to recall having that problem.
It was solved by correctly adding a finishing "." (dot) after each ip in the reverse-zone file (ie. db.206.257.200 or whatever)
you might want to check this.

correction:
a "." at the end of each URL .
(not ip)
