I've come across some web sites that give good tutorials for IP Subnetting:
- About IP Tutorial
- Learn to Subnet on howtosubnet.com
- IP Address Subnetting Tutorial
- IP Address and Subnetting for new users on Cisco.com
Test Question Example:
You have been allocated a 126.96.36.199 IP address for your network. At present we need 13 subnets. In the future we will need to allow for the expansion up to 28 subnets. You need to be able to connect up to 2000 IP addresses available in each subnetwork.
Devise an IP addressing scheme, giving the subnetwork, first host, last host and broadcast IP addresses for each subnet. Also specify the subnet mask you would use.
Use the methodology described next.
You will need to
i. Determine the required number of bits to borrow for subnetting.
ii. Determine the subnet mask
iii. Determine all subnet network addresses
iv. Determine the addresses of the first host, last host and broadcast on each subnet.
You need to include all the calculations and explanations for each item; no marks will be awarded for any unjustified correct answers.
Range: 188.8.131.52 to 184.108.40.206
Now, the others from the calc is:
2 - 220.127.116.11 to 18.104.22.168
3 - 22.214.171.124 to 126.96.36.199
The number of subnets will define how many bits of the IP address you need to use for the network portion of the address, and the number of hosts per subnet will define how many bits of the IP address you need to use for the host portion of the address.
Okay... you're given the Class B address 188.8.131.52. Normally, for a Class B address, 16 bits are used for the network portion and 16 bits are used for the host portion. At present, we need 13 subnets, but we must be prepared for future expansion. Therefore, we should allocate 28 subnets (yes, ignore the 13 subnet part - it's there to make sure you're reading the whole question correctly). That means we need to steal, at a minimum, 5 bits that we would normally use for host addresses and use them for subnets. Why 5 bits? Because 2 to the 5th power is equal to 32 (2 to the 4th power only gives 16 subnets... 2 to the 6th power gives 64 subnets). Even discounting the "all-zeros" and "all-ones" subnets, we still have 30 subnets we can use.
Okay, so how many bits does that leave us for host addresses for each of those subnets? Well, we used to have 16 bits... but we stole 5 for subnets. Is 11 bits enough to handle 2000 IP addresses per subnet? Let's calculate... 2 to the 11th power is 2048 - minus 2 addresses for the network address and broadcast address, and we've got 2046 available IP addresses per subnet. Barely enough!
Back to the subnet portion... how do you get the increase of 8 for each range? Here's how I look at it:
A /16 mask (normal Class B) has 1 big subnet, with an "increase" of 256 per range.
A /17 mask (stealing one bit for subnets) makes 2 subnets (provided you can use the all-zeros and all-ones subnets), with an "increase" of 128 per range.
An /18 mask makes 4 subnets, with an "increase" of 64 per range.
A /19 mask makes 8 subnets, with a 32 increase per range.
A /20 mask makes 16 subnets, with a 16 increase per range.
A /21 mask (stealing 5 bits, which is what you have), makes 32 subnets, with an 8 increase per range. Your calculations are accurate.

Here is a cool solutions article that gives a quick overview on what's new with this release.
- iFolder 3.0
- Improved NSS performance on Linux
- Novell Client for Linux
- iPrint enhancements, including iPrint client for Macintosh
- Improved Migration Capabilities
- Includes SLES9 SP2, NetWare 6.5 SP4, Novell Client for Windows 4.91 SP1
Novell Press Release
Novell said at the show that it--and its channel partners--can now resell support for the popular MySQL database. Waltham, Mass.-based Novell joins Dell, which said on Monday that it will offer MySQL Network, the subscription support for MySQL.
"This gives us a much broader reach than before. This is a big vote of confidence because we're still a modest-sized company," said Zack Urlocker, vice president of marketing for MySQL, Cupertino, Calif.
Some solution providers said having big-name support backup is critical. For example, Santa Barbara, Calif.-based Novacoast is a VAR and integrator but also ends up doing custom application work for customers, said CTO Adam Gray.
"Having Novell or Dell support helps us better support the customers,” Gray said. “They're both 24 hours a day, and if I'm up at three in the morning fixing something, it's nice to have that."
Keep in mind the support offerings when you choose your vendors!

In this article he mentions many troubleshooting techniques. He also recommends using a secondary IP Address and assigning it to iPrint.
"It is probably a good idea to get an IP address assigned to your iPrint service, since you can move it via a cluster, or even in case of a server failure. If all your users install printers that point at a service address (like iprint.yournetwork.com) instead of a server address (serverA.yournetwork.com), when you move it around, your clients will not need to reinstall the printer. If the IP of the service changes, then the printers look like new printers."
You can assign it as a Secondary IP address. At the console type:
add secondary ipaddress 10.0.0.5

To force a coredump in NetWare hold down these four keys:
SHIFT SHIFT ALT ESC and at the prompt type ".c "
Otherwise wait for the ABEND to happen but first prep the server:
1. Turn off ASR (Automatic System Recovery) in BIOS of server.
2. SET AUTO RESTART AFTER ABEND = 0
3. Follow TID 10083803
Coredump type? - - Choose 2
1) Full (all server memory)
2) Full w/o cache (all server memory except file cache)
Compress coredump? (compression will use less disk space, but is slower) -- Choose 1
4. Rename COREDUMP.IMG to COREBUCKY1.IMG (or something)
5. Send to Novell FTP Host and email Bucky or your Novell Support Person.
6. If possible email Bucky or your Novell Support Person a CONFIG.TXT report and ABEND.LOG file.
:LOAD CONFIG /ALL
It is possible to automate the process of collecting a coredump by following TID 10076467 and using DBNET6.NLM and DIAG500.NLM which is included with NetWare 6.5 SP2 and later.
Here is an example of a coredump.ncf file:
set auto restart after abend = 0
set cpu hot timeout amount = 0
?load diag500 -AUTODUMP -COMPRESS -d NETWORK -h 192.168.1.192
#on remote server 192.168.1.192, load imghost vol2: (volume sys: is default)
"Based on our tests, we think OES is a major breakthrough in Novell's long-stated intention to marry its directory and administrative applications to Linux. OES layers a highly competitive directory service onto Linux, provides decidedly evolved administrative and management components and offers very good, egalitarian client support."

The Server Migration and Server Consolidation utilities have been merged into one product under the name Server Migration Consolidation Toolkit (SMCT). It is downloadable off the internet.
For customers running with IBM Blade servers, we have been seeing an issue where people will lose access to the keyboard for their server. Engineering is working on a version of CIOS.NLM to fix this.
Mac directories with a trailing period (.) have a sharing violation when backup programs try to back them up. The backup programs skip these files. The problem is that files with the trailing period are being incorrectly shared between namespaces. Watch for a new patch.
- Watch for a new MM.NLM that fixes a performance issue on Mirrored NSS partitions. It will increase performance by 80 to 90 %.
- Watch for a new PARTFIX.NLM utility. I have the latest utility if you need this. Just email me.
Customer upgraded server from NetWare 6.5 SP2 to SP3 and now they cannot mount their volumes. They cannot see their volumes.
ERROR: Partition size exceeds device capacity.
SYS volume will mount but will deactivate quickly
Symptoms very similar to TID 10093547
Customer using IBM Hardware or Dell Hardware with PERC2.HAM and PERC2.CDM drivers v2.80
Dell PowerEdge 2650
IBM X series server model 225, 235, 345
This has been seen using the SCSIHD.HAM drivers also.
Error appears upon reboot and then the server hangs
TROUBLESHOOTING: back rev the perc2.ham and perc2.ddi or scsihd.ham and scsihd.ddi to nw65sp2 level drivers. This has worked on several servers.
Cause: One possible cause is that the new .HAM drivers fixed a problem in reported capacity, but the partitions have not yet been updated to accept the correct values.
Fix and Solution:
Run the PARTFIX.NLM utility with the /s switch first, then to repair use the /r switch.
Or check with Novell Support or myself to obtain the latest PARTFIX utility.
Once partfix is run, do a MM SCAN FOR NEW PARTITIONS to allow Media Manager to find the new partition, then do LIST PARTITIONS (look at the logger screen for output).
