ZZClear NLM A NetWare Enhancement from Scott Wertz


ZZClear is a replacement for Novell's NLICLEAR.NLM that ships
with NetWare 3.12. NLICLEAR clears NOT-LOGGED-IN connections
from your server after a time interval that you specify. This
is a nice feature, with one drawback: your users are constantly
faced with an Abort/Retry message each time they login because
their connection has been terminated. Worse, if you've got a
machine that automatically logs in after hours to run backups,
NLICLEAR may interfere with your backups.

ZZClear is similar to NLICLEAR, except that it only bumps user
connections when your server is low on free connection slots.
This approach reduces the inconvenience to your users (and the
number of support calls you get!). Better yet, ZZClear accepts
a list of node addresses that you never want bumped so that your
backups can continue as scheduled.


INSTALLING ZZCLEAR
- - - - - - - - - -
1) Copy ZZCLEAR.NLM into your SYS:SYSTEM directory.

2) If you wish to keep a list of nodes that should never be
knocked off the network, create a text file called ZZCLEAR.CFG
in the same directory as ZZCLEAR.NLM, and enter one line for
each node address. Be sure to enter the NODE address only;
if you include the network address, it won't work.

Novell includes a command called USERLIST in your SYS:PUBLIC
directory that you can use to examine node addresses. Just
type USERLIST /A.

Here's a sample ZZCLEAR.CFG:

1B38AD91
1B37D428
8000954632

3) Load it at the console screen. Just go to the console
prompt and type LOAD ZZCLEAR.



From now on, ZZClear will wake up once each minute and check the
number of free connection slots. If there are three or more free,
it goes back to sleep. Otherwise, it will search for NOT-LOGGED-IN
users that are NOT listed in the CFG file and it will terminate
their server connection.

NOTE: If you change the CFG file, you do NOT have to reload the NLM.
