Hi,

I have HP UX box :HP-UX B.11.23 U ia64 0468963392

The /etc/hosts file has entry as below
16.81.21.52 box1.gb.tel.com box1

When I use the command below,

$ping box1.gb.tel.com,the response is fine
PING box1.gb.tel.com: 64 byte packets
64 bytes from 16.81.21.52: icmp_seq=0. time=0. ms
64 bytes from 16.81.21.52: icmp_seq=1. time=0. ms
64 bytes from 16.81.21.52: icmp_seq=2. time=0. ms

But when I tried using the command below,there is no respone
$ping box1

1)Seems like ping command is not looking into /etc/hosts file to get
the ip address
2)Also tried telnet command...similar behaviour is seen.

Tried googline but not of much use.Any idea what could be the reason.

Regards,
Mehaboob

you need to change your resolv.conf to lookup hosts in /etc/hosts.

Ok, check /etc/resolv.conf, it should contain domain name and
nameserver info.

then start sam -> networking & communications -> name service switch ->
actions -> configure name service switch

1st should be /etc/hosts 2nd should be DNS all actions "try next
source"

that should make it try /etc/hosts then the nameservers

That would be /etc/nsswitch.conf rather than resolv.conf.

Hi,

Thanks a lot for the reply.
Updated the /etc/nsswitch.conf to look into the hosts files and DNS.

Thanks,
