[ale] DNS problems

[dZothMuellarg]

^
^I've got a DNS problem I was wondering if anybody could help me with.
^I've got a machine dialing into the net via SLIP and I want named to
^access know something about the Internet once the connection is established.
^However, I can't get it to work.  I've turned debugging on named on but
^I don't know what any of this stuff means.  Can anyone help.
^    
^This is a request for ns.advantis.com using nslookup.  alc.com is the domain
^name I'm using (which is not my legal domain, but I shouldn't think it would
^matter).

Lots of people have told you not to use named, assuming you are a
single machine....  But if you are a proxy than named makes more sense
and if you aare running DNS for ALC (which I know you might jusrt be
doing) then you need some answers.

Turing Debug on is a dangerous thig, it gives too much info.  Rather user
set type=any

I have an example at the end. 

^req: found 'ns.advantis.com.alc.com' as 'alc.com' (cname=0)

It is trying your.reuest.your.domain, which is standard.  But your
domains name server probably only has alc.com, thus a dead end.
Now we are checking the forwarder, you do have forwarders in your root.cache?

^store_name_addr:s:I.ROOT-SERVERS.NET, a:[192.36.148.17]
^nslookup: NS "alclnx.alc.com" c=1 t=2 (0x1)
^store_name_addr:s:alclnx.alc.com, a:[199.120.240.13]
^NS 'alclnx.alc.com' contains our address
^forw: nslookup reports danger

It seems to find your local server as a forwarder, recursive problem

^free_nsp: alclnx.alc.com rcnt 1
^ns_req: answer -> [127.0.0.1].1112 fd=7 id=5 Local

Thus 127.0.0.1 is returned by your local server, which is wrong

[root at zotnet bin]# nslookup
*** Can't find server name for address 206.26.96.221: Non-existent host/domain
[Damn need to fix that!  New IP as of 1 hour ago...]

Default Server:  calypso.ploexnet.com
Address:  206.26.96.225

> ns.advantis.com
Server:  calypso.plexnet.com
Address:  206.26.96.225

Non-authoritative answer:
Name:    ns.advantis.com
Address:  192.124.113.30

[Hmm, got an answer what else is there???]

> set type=any
>  ns.advantis.com
Server:  calypso.plexnet.com
ddress:  206.26.96.225

Non-authoritative answer:
ns.advantis.com internet address = 192.124.113.30

Authoritative answers can be found from:
com     nameserver = A.ROOT-SERVERS.NET
com     nameserver = H.ROOT-SERVERS.NET
com     nameserver = B.ROOT-SERVERS.NET
com     nameserver = C.ROOT-SERVERS.NET
com     nameserver = D.ROOT-SERVERS.NET
com     nameserver = E.ROOT-SERVERS.NET
com     nameserver = I.ROOT-SERVERS.NET
com     nameserver = F.ROOT-SERVERS.NET
com     nameserver = G.ROOT-SERVERS.NET
A.ROOT-SERVERS.NET      internet address = 198.41.0.4
H.ROOT-SERVERS.NET      internet address = 128.63.2.53
B.ROOT-SERVERS.NET      internet address = 128.9.0.107
C.ROOT-SERVERS.NET      internet address = 192.33.4.12
D.ROOT-SERVERS.NET      internet address = 128.8.10.90
E.ROOT-SERVERS.NET      internet address = 192.203.230.10
I.ROOT-SERVERS.NET      internet address = 192.36.148.17
F.ROOT-SERVERS.NET      internet address = 192.5.5.241
G.ROOT-SERVERS.NET      internet address = 192.112.36.4

[Hmm, I can look to the root servers for info... or look at it..]

> server ns.advantis.com
Default Server:  ns.advantis.com
Address:  192.124.113.30

> ns.advantis.com
Server:  ns.advantis.com
Address:  192.124.113.30

ns.advantis.com internet address = 192.124.113.30
advantis.COM    nameserver = ns01.ny.us.ibm.net
advantis.COM    nameserver = ns01.ca.us.ibm.net
advantis.COM    nameserver = ns02.ca.us.ibm.net
advantis.COM    nameserver = ns.advantis.com
ns01.ny.us.ibm.net      internet address = 165.87.194.244
ns01.ca.us.ibm.net      internet address = 165.87.201.244
ns02.ca.us.ibm.net      internet address = 165.87.201.243
ns.advantis.com internet address = 192.124.113.30

Lots more info now!!!

Read man named, man bind, and Olaf's book, and the how to's
It is actually simple, just lot's of nomenclature saying the same thing.
