dhcp clients conn test

Hi,

I have a couple of hosts that use dhcp that I want to test through their windows hostname.

The hobbit server has samba setup so that fping -Ae [hostname] correctly resolves these windows names.

If I add them to hobbit using

0.0.0.0 [hostname] #

(which I understand is correct for a dhcp address?)

It gives me bbtest-net: Cannot resolve ip for host [hostname] in the logs and the page in hobbit states DNS lookup failed and says 0.0.0.0 up for Xms. How does hobbit do the conn test in this situation and is fping failing to work correctly from inside hobbit?

I'm running 4.1.2p1.

Apologies if this has been covered before but I couldn't find anything in the archives.

Thanks for any help,

Craig Whilding
