Basic DNS resolution problem

[Peter Kovacs 1.0rc]

Hi,

I am completely new to HPUX.

The system has an /etc/hosts file with the following entries:

10.0.0.104 apollo apollo
127.0.0.1 localhost loopback

(10.0.0.104 is the system's own IP address.)

Still, there seems to be DNS resolution problem:

# ping apollo
ping: unknown host apollo

Should I, perhaps, change the content of the /etc/resolv.conf file? This file currently contains the following entries:

# cat /etc/resolv.conf
domain localdomain
nameserver 10.0.0.100
nameserver 10.0.0.1

(The nameservers listed don't now about apollo.)

Any help appreciated.

Thanks
Peter

Peter,
and welcome to the forums !

Have you checked your nsswitch.conf to check in what order you will try to resolve your hostname target.

You can modify via SAM or editor.

See "man nsswitch.conf"

We normally use the order:
files (/etc/hosts)
DNS

Peter,

Agreed with the above answer, your /etc/nsswitch.conf your be looking like this:

# cat /etc/nsswitch.conf
#
# /etc/nsswitch.files:
#
# @(#)B11.23_LR
#
# An example file that could be copied over to /etc/nsswitch.conf; it
# does not use any name services.
#
passwd: files
group: files
hosts: files [NOTFOUND=continue] dns
ipnodes: files
services: files

Regards,

Jaime.
