Re: [MLUG] DNS?

[Neil Bradshaw <EMAIL:PROTECTED>]

Whenever you use DHCP, it will automatically spit out a hostname for
you. You can have a local alias, but you need to use the hostname MU gives
you (like mu-255255.dhcp.missouri.edu, where 255255 is the last two octets
of your ip address (in this example, it would be 128.206.255.255)). If you
don't use that hostname, the IAT Services secret police will find you.

Actually, we have no secret police. But you could cause network
problems by using DHCP IPs and illegal hostnames. No DNS servers would
point at that IP, so unless you make your own DNS and reverse DNS lookups
probably won't work. And for the love of everything holy in this universe,
do not make your own DNS server. BIND is a security nightmare, and beyond
that it can be a real pain to set up. Not only that, if people start
pointing their DNS resolutions at your DNS sever and it congests the
network, your port might get shut off :( Beyond that, I believe it is
against MU policy for TCP SYN packets to be accepted on DHCP addresses
(basically meaning in a nutshell that you can't be a server on a DHCP
address). Obviously, we aren't going to beat you with a sucker rod if
you're using your machine to send yourself files remotely, but running a
server with a DHCP address isn't kosher as far as I know.

If you want a static IP and a hostname associated with your machine, talk
to the help desk. I think there's a charge for getting one, and you're
most likely to be stuck in a subdomain unless you have good reason not to
be there (like host.iats.missouri.edu or host.cecs.missouri.edu as
oppossed to host.missouri.edu).

Boom?
