Re: test network DNS server w/o Internet access: Is it possible?

[Robert Threet <rthreet@yahoo.com>]

Interesting...  Theoretically, it sounds like it might work.  That's
why I like to bounce this stuff off of you guys!  Lots of good
answers.  Thanks to all!

Since my test network is running fine, I'm gonna go with that.  

BTW, I was amused at how easy the Linux box was to set up in
comparison to the two Sun boxes.  WAY easier than the Solaris 8 and
Solaris 2.6.  Man, is 2.6 a pain!  But you guys already knew that.
