This is working fine on another CentOS system. This particular install where host command is failing is trimmed down install using kickstart file. It is working on a system where install is default 'Server non-GUI', option given during interactive CD install. I guess this has to do with some missing package. Any clues??

I have modified /etc/hosts file with IP address and hostname entries. However, host command is returning 'Host vhost1.example.comhttp://vhost1.example.com/ <http://vhost1.example.comhttp://vhost1.example.com/> not found: 3(NXDOMAIN)'. Also, apache is returning error on start as '[error] (EAI 2)Name or service not known: Could not resolve host name vhost1.example.comhttp://vhost1.example.com/ <http://vhost1.example.comhttp://vhost1.example.com/> -- ignoring!' . The ssh worked fine and resolved the hostname correctly (ssh from same system to itself - just for test). Am I missing something here? I thought /etc/hosts will be referred for all lookups. Any help??
the 'hosts' command (as well as dig, and nslookup) go directly to DNS, they do not look at /etc/hosts or nsswitch.conf for that matter. Apache may well go to DNS also, since your local /etc/hosts file is not recognized by any systems outside the localhost, and apache IS a server.
