>From stefan@crux.astro.utoronto.ca Wed Oct 21 18:22 EDT 1998 To all astronomy computer users, Due to some confusion, even on my part, I think I need to put in writing the procedures for hooking up a computer to any network, if that computer is to belong to the "astro.utoronto.ca" domain. I hope this alleviates any further confusion ... Stefan Mochnacki, (acting systems manager) ============================================================================ Procedure for assigning an Internet Protocol (IP) number and name in the astro domain: When you want to hook up a computer and have it exist as part of the "astro.utoronto.ca" domain, you need to notify the Astronomy Systems Manager so that it can be entered in our Domain Name System (DNS) database primary files, which are kept on the departmental server "lepus". (a) If you are at DA or DDO: Select a name for your computer, test to see whether it is free by running the "nslookup" command on an existing running machine: nslookup myname.astro.utoronto.ca where "myname" is your chosen name. You should get a negative result. You should also try: nslookup myname.cita.utoronto.ca nslookup myname.physics.utoronto.ca since we don't want to duplicate names with our closest neighbours. If "myname" is OK, send Hugh an e-mail, specifying where you are installing the computer. If at DA, Hugh will look after the wiring (or, if necessary, arrange for it to be done). At DDO, Hugh also usually looks after wiring (e-mail him). Also, specify what sort of computer it will be, under what sort of OS (Linux is much preferred). Hugh will reply with an assigned IP number for you. It will become active within a few hours to a day, immediately if you use "lepus" as your nameserver. (b) If you are elsewhere (e.g. Scarborough or Erndale): Check the preferred name as above. Then send me the name AND the IP number assigned to you by your local network administrator, or ISP (if, wonder of wonders, you can swizzle a PERMANENT IP number out of them. Tell 'em that you "don't support DHCP", and don't use their software). The response is as above, except you don't need to hear from Hugh. If you use nameserver=128.100.89.2, it'll be immediately active. If you use your local or ISP nameserver, the DNS change may take a day or so to propagate. (c) Note regarding the other network setup numbers, as required by the network configuration procedure of your computer: At DA: Gateway = 128.100.89.1 Nameserver = 128.100.89.2 Netmask = 255.255.255.0 At DDO: Gateway = 128.100.77.224 Nameserver = 128.100.77.6 and/or 128.100.89.2 Netmask = 255.255.255.0 Elsewhere: Gateway = assigned locally or by ISP Nameserver = local, or 128.100.89.2 Netmask = assigned locally or by ISP (d) E-mail aliases: Please also send Hugh your actual e-mail address, so that he can enter an alias for you as "myname@astro.utoronto.ca". If you have several aliases, please let him know so that he can put all of them in (e.g. I'm both "stefan" and "mochnacki" at astro ...) You can have a non-astro actual address entered as an "astro" mail alias. This especially applies to CITA-affiliated astronomy denizens.
