Answer / guest
If you give "ping hostname" the server will give the result
from /etc/hosts file & if you give "ping hostname.domainname"
then i will search through internet.

Dear Colleagues
/etc/nsswitch.conf decides on the services used for a
variety of name resolution requirements
the part of interreset for this question is :
hosts: files ----> this will only resolve hostnames
from the /etc/hosts file
but if you add 'dns' next to files ; then you activate the
name resolution service [otherwise called to DNS client] ;
that used to resolve names through hosts file to resolve
names [ this time through dns naming model] from the server
configured in /etc/resolve.conf
which may look something like this
myhost# cat /etc/resolv.conf
domain mydomain.internal
search mydomain.internal
options retry:1 timeout:1
nameserver 10.234.206.73
nameserver 10.10.98.38
this file direct the name resolution through the configured
nameserver ; and will search for a given hostname through
hosts file first then through DNS resolution by appending
the configured domain name

If your are pointing to the DNS server why you need to add
it in a /etc/hosts
if you are not able to ping through hostname just type "dns"
in /etc/nsswitch.conf file if you try to access through
hostname it read the nsswitch.conf file this file will
point to dns server.

Hello Everyone, One of our servers is showing a strange issue, let me paste the output Code: root # uptime 4:37pm 3 users, load average: 0.00, 0.04, 0.04 Its been running since months but you can see after time there isn't any output like up 191 days(s). Even the who command with b and r option isn't giving any output. Code: root # who -b root # root # who -r root # the date command displays correct output. I am not sure but is it because someone has played with utmpx and wtmpx files, is reboot the only solution we have. Can anyone help us since we don't intend to reboot the server for such a reason and also no one has complained till yet.
