DNS issue.

[kpatel786]

We have added on HPUX 11.11 server a new DNS server entry (windows 2003) in /etc/resolv.conf file.

We are able to ping the server:
(hqb) [SU] # ping 10.5.3.180
PING 10.5.3.180: 64 byte packets
64 bytes from 10.5.3.180: icmp_seq=0. time=0. ms
64 bytes from 10.5.3.180: icmp_seq=1. time=0. ms
64 bytes from 10.5.3.180: icmp_seq=2. time=0. ms
64 bytes from 10.5.3.180: icmp_seq=3. time=0. ms
64 bytes from 10.5.3.180: icmp_seq=4. time=0. ms
64 bytes from 10.5.3.180: icmp_seq=5. time=0. ms
64 bytes from 10.5.3.180: icmp_seq=6. time=0. ms

----10.5.3.180 PING Statistics----
7 packets transmitted, 7 packets received, 0% packet loss
round-trip (ms) min/avg/max = 0/0/0


But the nslookup is not able to resolve the the dns server name.

(hqb) [SU] # nslookup hpi.dhq.lr.org
*** Can't find server name for address 10.5.3.180: Non-existent domain
*** Default servers are not available
Using /etc/hosts on: hqb

Trying DNS
*** can't find hpi.dhq.lr.org: No response from server

The same ip is getting resolved for other Linux and windows servers withing our network, however the same is failing for all the hpux boxes. Kindly provide suggestion/inputs to resolve the same. Thanking you in advance.

Hi,

What is the content of /etc/resolv.conf file?

Rgds.

[kpatel786]

(hqb) [SU] # more /etc/resolv.conf
search internal.lr.org dhq.lr.org lr.org
nameserver 10.5.3.180

[Jose Mosquera]

Hi,

Add this first line:
domain

Rgds

[kpatel786]

(hqb) [SU] # more /etc/resolv.conf
search internal.lr.org dhq.lr.org lr.org
domain 10.5.3.180
===

[SU] # nslookup hpi.dhq.lr.org
Using /etc/hosts on: hqb

looking up FILES
Trying DNS
*** can't find hpi.dhq.lr.org: No response from server


Getting the above output.

[Jose Mosquera]

Nop!

/etc/etc/resolv.conf:
domain
search internal.lr.org dhq.lr.org lr.org
nameserver 10.5.3.180

Also, What is the content of /etc/nsswitch.conf file?


Rgds.

[kpatel786]

(hqb) [SU] # more /etc/nsswitch.conf
#
# /etc/nsswitch.conf
#
# This file is for use on systems that are not running DNS or NIS.
#
# In this case we request that the resolver looks in local files only.

# See the Adminstering Internet Services Manual and the switch(4) man

Have tried putting the entries as you said, but the same is not working.

Do you know if there is, in fact, and entry in the dns (located at 10.5.3.180) for the hostname hpi.dhq.lr.org ?

Check with your Network administrator to see that UDP port 53 (domain) is not blocked by a firewall rule.
