Name resolution with no nameserver indicated
I have a RHEL cluster -- and no /etc/resolv.conf file and only an /etc/hosts file for name resolution. The /etc/nsswitch.conf file has the hosts line --> hosts files dns. This seems to be as expected -- however, on 'nslookup', I can try to resolve a hostname that is defined in my hosts file yet I get ";; connection timed out; no servers could be reached".
There should not be an attempt to query a nameserver as one is not defined -- I have checked the IPTABLES and they are off on one server and on on a few others -- yet the result is consistently the same.
I am able to successfully ping/telnet/SSH from all the nodes defined in the /etc/hosts file -- it is just that the 'nslookup' command fails.
Any ideas?
Thanks!
Dan
