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

	It's correct only if the dhcp sets automatically the DNS entry for your hostname. hobbit check the name with a DNS resolution.

	can you set your dhcp server to add automatically your hostname in the DNS ? 
	could you also try an "nslookup hostname" from your hobbit server ?

Nslookup fails as these hosts are not on dns, they will only resolve through wins.

 
The dns server is running on solaris while the dhcp servers are windows based. Im not sure how easy (if possible) it would be to configure the dhcp server to add clients to the dns.

 
Thanks

The dynamic dns does it, but only to the dhcp server's dns, if it runs. Perhaps can you add a subdomain for dhcp clients, and add this subdomain to your domain searchlist on the hobbit server. (or add the dhcp server's to your dns server's list on the hobbit server).  As long as nslookup fails, bbtest-net will also fail.  N F

Ok thanks, ill have to see if I can get this set up on the dhcp servers on each subnet we have. They arnt really under my control so ill have to check with those involved. Shame as the server can resolve them through WINS now :-(.

 
Thanks
