<FONT COLOR="#000000">Can't really explain it. I am using the same host to respond to this email which mean I can't be having nwtwork problems. Could there be a specific port I need to have iptable allow? Nothing else make sense as to why it should work for you while its failing for me.</FONT><BR>
<FONT COLOR="#000000"> As for what I was trying to so, I was helping a friend set up evolution. He currently use a webmail and I wanted to poke his mail provider IP with nmap and see if pop port is open. Unfortunately, I only had domain name with me, and nmap doesn't work very well with domain name for me. I hence tried using "host" to extract the Ip and that is how I landed in above issue.</FONT><BR>
<FONT COLOR="#000000"> Thank you for your help. At least I know I am in the write path, just getting killed by some funky issues that I can't fathom</FONT><BR>

That usually means that your /etc/resolv.conf has improper "nameserver" addresses.<BR>
<BR>
According to my man page, the way that you are using host uses the standard DNS UDP protocols, so if DNS works, then so will host.<BR>
<BR>
An alternative command, that I use regularly is dig. Dig provides the same functionality except it outputs in BIND format which is not as easy to read.<BR>
<BR>
To see if it is your /etc/resolv.conf configuration find a DNS server IP address and put it on the command line: e,g:<BR>
<BR>
host tlug.ss.org 216.16.235.2<BR>
<BR>
If that works then check your resolv.conf.<BR>
