Topic: dns dhcp lan addresses

[dwater]

Hi,

How can I make SME's dns resolve addresses it gives out via DHCP?

Hrmph.

Actually, this seems to work intermittently. EG, here it resolves with 'host' but not with 'dig' :

Code: [Select]


$ host ricardo
ricardo.x.x has address 192.168.x.11
$ dig ricardo

; <<>> DiG 9.2.1 <<>> ricardo
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 47894
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;ricardo.                       IN      A

;; Query time: 1 msec
;; SERVER: 192.168.x.1#53(192.168.x.1)
;; WHEN: Wed Dec 29 02:17:15 2004
;; MSG SIZE  rcvd: 25


Any ideas?

Max.

Thanks. It sounds like it should have done the job, but it didn't seem to make any difference.

I have just noticed one more thing though; dig will resolve fine if I give fully qualified names :

Code: [Select]


$ dig ricardo

; <<>> DiG 9.2.1 <<>> ricardo
;; global options:  printcmd
;; Got answer:

[mwaterman@truth ~]$ dig ricardo.x.x

Any ideas? Perhaps this is 'by design' since 'host' seems to work.

I will see if trouble symptoms are still there (printers disappearing).

Thanks!

.. you will need to refresh your leases on your w/s's in order for the SME box to track the system name/ip allocation.

This contrib has worked for me on 30 plus systems without fail!

Hrm. I think this might be a slightly different problem.

I mean, even the dhcp/dns server itself does not resolve (and I'm doing this while logged into that server) :

Code: [Select]


[x@truth ~]$ host truth
truth.x.x has address 192.168.x.1
[x@truth ~]$ dig truth

; <<>> DiG 9.2.1 <<>> truth

I used to use dnsmasq to do this when I was running on Fedora Core, and I don't recall the same problem - though I don't often use 'dig'.

I don't know what this issue is, but I don't think it is the cause of my 'woes', so I'll let it drop.

It does seem to have solved the strange hostnames it was giving the clients, so that is it's purpose, I think.

I'll take my printing woes to another thread.

Thanks for solving that problem at least

Max.
