Thanks Jeremy! That is useful information. I hope you have time to read/answer a couple of things I am inserting below: On 1/18/07, Jeremy C.

Should I have known or been able to learn this easily in some fashion? I had assumed there was a difference but had no clue where to look to find the difference. When using gethostbyname, it uses nsswitch.conf, host.conf or other > chooser to select which sources for DNS lookups to use and what order to > use. I thought of nsswitch but it was close to the end of the meeting and had no time to read the man page. I will do so. Actually I remembered it affected lookup sequence from my job back in the 80-90's but not how or how to use it. Commonly your local file /etc/hosts is used first and then normal DNS > lookups is used if needed.

I was not sure if the file might be cached or how to force a re-read so the reboot was to ensure that. I did not think to check /etc/resolv.conf since we were able to surf the net. But now I think on it maybe we were bypassing dnsmasq on the router and going directly to the ISP dns servers. I will ask the owner to check this. I would have thought though that /etc/resolv.conf would have been updated as a result of the DHCP request when the system was rebooted. Am I wrong there? Jeremy C.
