Re: [webmin-l] BIND slaves

[<da...@so...>]

Hi Jamie,

THis is where I'm stuck. All of the relevant info comes up on the sytem 
information page, hostname, OS VM version etc. All the boxes add correctly 
when adding webin servers in the webmin servers mod. All the added 
servers work fine in the clusters mods. It's just the BIND mod I'm having an 
issue with, I get the error when trying to add a slave cluster. 

In the slave cluster Module all of the servers are listed in the drop down 
menu by hostname. If I select one, then click add, I get the fore mentioned 
error:

Failed to add server : Could not work out this system's IP address. You
> should set the Default master server IP for remote slave zones on the

I now that I detect by your note that the response is for the complaining 
machine, I took off the auto detect from hostname and inserted the 
appropriate IP address and it worked fine. That's weird as it only matters to 
the primary and secondary nameservers. The question still is, why doesn't 
BIND detect the IP from the hostname when everything else does?

Thanks,
Dan

PS: can you have Joe get back to me on VMPro pricing in bulk?? thanks
