[PLUG] Virtual hosting IP and namebase

[Josh Orchard]

Thank you.  This will solve the issue with the apache server.  I can put
them in order and if they use the ip number then I can have the default go
to a main page of a generic page.

Now I just need to see if proftp has this same ability. I think it does
but I really don't know.

I guess ssh will have the same limitation but that isn't so bad as they
have to have a user account.

Is there a way to limit who can ssh into a box?  That would work.


Thanks for all the answers everyone.  I see this will not be so difficult.
Minus the fact that I think I'll have to add a DNS server to my box also.
That is just to give me more control and flexibility.
