(LONG MESSAGE) Keywords: Novell 3.## Message-ID: Date: 13 May 91 05:22:34 GMT Followup-To: bit.listserv.novell Organization: Rutgers Telecommunications Lines: 112 Sorry to cross post this message but I will like to know something about netware under 3.##. If this has been ask before sorry but I have not be reading these groups for the past 2 months. Previously, when our group in Computer Services install 3.10, we found out that Novell change the rules on us with Novell network numbers. Novell requires an internal network number that has nothing to do with the particular novell network number involved (see picture below). This internal network number is advertised when I do a "show novell servers" on a cisco router running novell routing. I "assumed" incorrectly that it would show me that external network number of the particular media cisco was connecting the server to. So we had to come up with a new numbering scheme throughout the university novell network in order to know what was on what novell network media if we had redundant networks. Cisco============================Server-A================================Cisco ^-novell network2(external) ^----novell network 1(internal) ^ | novell network 3(external) This past Thursday, a collegue of mine ask for my help bringing up 3.11 and appletalk services. Again, novell requires an internal appletalk network number besides the external appletalk network number. And yet again, the network number being adverstise is the internal number instead of the media network number. So for every novell appletalk server that is brought up, 2 appletalk network numbers are required. Below is an output from both novell and appletalk from cisco novell services and CAP package on a SUN. We at the university base our protocol network numbers on the IP network numbers. I will explain further below. Cisco (busch-gw) ----------------- busch-gw>show novell server Type Name Net Address Port Hops Interface 4 RUCS-PROTO 80065315.0000.0000.0001::0451 2 Ethernet4 .... 107 RUCS-PROTO 80065315.0000.0000.0001::8104 3 Ethernet4 .... busch-gw>show novell interface ethernet 4 Ethernet 4 is up, line protocol is up ... Novell address is 80065300.aa00.0400.20f4 ... So for novell protocol, a Novell server is on IP network 128.6.83.0 (subnetted Class B network) with host number 15, it's hex-equivalent external novell network number is 80065300 (based on IP network number) and internal network numbers 80065315 (based on IP host number). You will notice that the SAP services are showing up as network number of 80065315 but cisco interface indicates that it is network 80065300. madness$/usr/local/cap/atlook Etalk-83 -------------------------------------- abInit: [ddp: 18.00, 119], [GW: 18.00, 1] starting Looking for =:=@Etalk-83 ... 1 - RUCS-PROTO:AFPServer@* [Net: 83.1 Node: 1 Skt:253] 2 - busch-gw:ciscoRouter@Etalk-83 [Net: 83.0 Node: 1 Skt:254] For appletalk protocol, we multiple 256 times the subnet number plus a number from 0 to 256 to come up with the decimal equivalent appletalk. So for the above appletalk numbers, these services are on IP network 128.6.83.0. My appletalk sun is on appletalk network 18.00 (call KIP notation). I query appletalk zonename "Etalk-83" for it services. RUCS-PROTO is a appletalk novell server advertising AppleShare services. Noticed that it shows it is on network 83.1. The cisco router, busch-gw, shows the correct network number (83.0) on that media. RUCS-PROTO does not have any other network media cards in it. RUCS-PROTO is sending out correct network routing information on that particular media of 83.0. My short term problem is as follows: I, as a network manager, will have to have an idea that it is on IP network of 83 should problems happen. It is hard to teach this easily to operators when I shut down novell (or appletalk) on the network in question and users start calling them for help (I cannot print to foobar.). What are other organization during for network number and a global database for these different protocols? I am thinking of merging the appletalk, decnet, IP and novell network databases together so I (and others) can use the IP domain system to find out network numbers and services. A larger long term problem has to do with the number of network numbers. There seems to be enough novell network numbers to allow 2 network numbers to go with a novell network server but I question the appletalk scheme since you only have 64K (256 network numbers per media) network number under appletalk phase 2. You would need only 256 appletalk novell servers times 256 media before you run out of network numbers. I know this is lot of machines but there are a lot of departments/organizations at our university. They have separate needs. Also with the talk about connecting with other university network services (through protocol tunnelling), this number can easily become small quickly. Rutgers university has already over 90 AppleTalk and 40 Novell media networks in one campus (less than 2 years). Different organizations will use different gateways/routers to get to these services. Since our group plans on campus/university scale, I can easily see novell services being used more and more to combine IBM pc and Macintoshes services at the university. Again, what are other organizations doing about this? Thanks for any information you can supply. -- Kevin Hobson Internet: hobson@rutgers.edu Rutgers - The State University UUCP: {backbone}!rutgers!hobson P.O.
