Unable to get name resolution from RHEL 5 /etc/hosts.

/etc/nsswitch.conf includes:

hosts: files dns

Example: /etc/hosts contains:
172.113.100.1       testsservername

host testservername returns: Host testsservername not found: 3(NXDOMAIN)

Thanks

host command will query DNS not /etc/hosts file

You can query like

getent ahosts testsservername

What is in your /etc/host.conf ?

It should contain:

order hosts,bind

try ping, which will use the service is nsswitch.

try:

ping testservername

It should show the IP address it gets from /etc/hosts.

Responding to several comments:
/etc/hosts.conf does contain expect order = hosts,bind

ping does resolve to the expected address so /etc/nsswitch.conf or host.conf acting as expected.

getent hosts [hostname] provides what I need.
