- At our group we currently have a Sparc1, a Sparc1+ and a Sparc IPX.
- Chances are that this number will be steadily increasing over the next
- years. Another possibility is that more workstations from other vendors
- (SiliconGraphics/HP, some already present) will be integrated with the
- machines of our group. Ofcourse the usual bunch of PCs is on the network
- as well (IPX as NFS fileserver).
-
- We are part of the Universtiy of Twente in the Netherlands.
-
- The DNS-zone for the university is utwente.nl
- Our faculty is Mechanical Engineering (Werktuigbouwkunde), WB for short.
- The DNS zone will be wb.utwente.nl
-
- Our group is Mechanical Automation (WA for short).
- Now, throw in our three Sparcs. We will be using NIS and chose domainname
- wa.wb.utwente.nl, because 1) it's a subset for all wb-machines, hence
- wb.utwente.nl is not Ok, 2) wa is beneath wb in the hierarchy, hence
- we tack on wb.utwente.nl.
- (BTW we are (as university) on the Internet, and our faculty has its
- own subnet, which contains bridges, but not routers)
-
- But now our Network Administrator (responsible for wb.utwente.nl) does
- not allow us to use mail addresses like John.Doe@wa.wb.utwente.nl, but
- only ones like John.Doe@wb.utwente.nl. The way he wants to implement it
- is to give every member of WB with an account on some machine in the
- department an mail alias on the central mail routing machine (for
- wb.utwente.nl):
- John.Doe@wb.utwente.nl: johnd@sparc1
-
- His argument is that the professors tend to change the name of the
- research group so often, which in the past has led to undeliverable
- mail. The central mail routing machine does not have DNS (Hence no MX
- records) and kicks all its mail upstairs to the mail exchanger for
- utwente.nl. If we want to implement DNS, we have to bypass the central
- machine anyway, so why have Mail aliases for our users on the central
- machine (did I explain the extra difficulties of adding/removing accounts
- yet?).
-
- Because I do not understand everything about mail routing/DNS and NIS
- naming I cannot convince our Network Administrator. The only thing I
- can throw at his feet is that he knows nothing about Unix (and still
- has to administer the central machine, running HP-UX), and that he
- knows only little of what's going on on the Internet. He also knows
- little of DNS (hey, he's not even running it!) so every difficulty
- he encounters is solved by the people responsible for utwente.nl,
- who are not aware (yet) of subdomains in wb.utwente.nl.
-
- What I need now is one or more from the list below:
- - Lots of flames telling me I'm doing it all wrong and I can have
- wb.utwente.nl as last part of the mail-address, for users in the
- NIS-domain wa.wb.utwente.nl or some other pointers in how to get
- things running
- - Good, convincing reasons why our Network Administrator is wrong,
- so I can slap him around his ears with that
- - Suggestions how to do it (implementing NIS/DNS)
- - Suggestions why not implement either NIS or DNS or both (but they
- offer a lot in our case)
-
- (I think the solution of our NA with the mail aliases is silly and
- will break eventually;
- When I'm gone (in about a year) there probably will be no system
- administrator anymore, and maintenance will have to be done by a
- volunteer who cannot spend all his time on administration, so I
- need to leave a system which is easy to administrate, while for
- non-usual problems help can be called in from others at our
- university)
-
- Sorry for the long posting, but it's difficult for me to state
- exactly what it is what I want, because I just don't understand
- everything and the FM was not of much help in getting the big
- picture in our situation....
-
- I will greatly appreciate any comments you have, preferably sent to
- me by e-mail.
