Re: [cobalt-users] "Spoofing" the Qube

["Franklin S. Werren" <fswerren@xxxxxxxxxxxx>]

The easy way is to use the internal DNS server
on the Qube 2.... Works for me...
Set up a second computer for a second internal DNS
If you do not understand DNS you are in for alot of studying...
I also have used this for several of my commerical customers
who use Webservers on site....
Remember you need to use NAT to get away with an internal DNS

Another way is to add a host file to each computer but if you change
something
you have to re-edit all the hosts files.

Good Luck!!!
