APPENDIX P -- Running RBBS-PC on a NETBIOS network P-1
APPENDIX P -- Running RBBS-PC on a NETBIOS network
--------------------------------------------------
CONFIG parameter 162 allows the SysOp to select an environment for running
multiple copies of RBBS-PC. One of the environments is "DOS SHARE," which
allows a large number of LANs to support RBBS-PC. Any LAN that is
"NetBIOS" compatible should allow RBBS-PC to run multiple nodes, since the
DOS SHARE utility is usually supported with all NetBIOS LANS. Operating
RBBS-PC on a network which supports the NETBIOS interface is therefore very
simple. Outlined step-by-step, the procedure is as follows:
1) Install and load your network software.
2) Configure RBBS-PC for the network environment.
3) Prepare files which are to be shared, but not written to.
Let's discuss these items in detail.
INSTALL AND LOAD YOUR NETWORK SOFTWARE
Obviously, for each different network, this procedure will change.
This manual doesn't attempt to replace or augment the documentation
which accompanied your network software. It only covers how to set up
RBBS-PC to work with a NETBIOS LAN. The assumption is made that you
can, and have, correctly installed your network.
However, so that you understand what we mean by "install and load", we
will present a generic description here. (It should be noted that
there are certain similarities between all NETBIOS LAN products.)
First, the "core" of the network software must be loaded after you
boot the machine (e.g. the NET START command). Next, any of your
computer's resources which others require access to must be "shared"
(e.g. the NET SHARE command). And finally, any resources which your
computer requires access to must be "used" (e.g. the NET USE command).
Please note that NET START, NET SHARE, and NET USE are all examples of
the commands used by the IBM PC LAN Program. Your actual commands
might be different.
CONFIGURE RBBS-PC FOR THE NETWORK ENVIRONMENT
Begin by running the RBBS-PC CONFIG utility. Set parameter 162 to
"6", which tells it that RBBS-PC is running on a NETBIOS LAN. (Please
check parameter 161 while you are there, also, and make sure that it
is correct for the number of nodes you intend to run.)
You will notice, when you select parameter 162, the reference to the
DOS utility SHARE.EXE. This utility must be loaded in order for a
NETBIOS LAN to function properly. The startup command for most
networks will cause SHARE.EXE to be loaded (i.e. when the NET START
command is issued, the network looks in the current path for SHARE.EXE
and loads it).
If, for some odd reason, your network does not automatically load
SHARE.EXE, you will need to perform this task manually in your
AUTOEXEC.BAT file (DOS 4.x users can opt for the "INSTALL=" option in
their CONFIG.SYS files).
PREPARE FILES WHICH ARE TO BE SHARED, BUT NOT WRITTEN TO
RBBS-PC 17.3A TECHNICAL REFERENCE MANUAL P-2
Once RBBS-PC is aware of the fact that you're running on a NETBIOS
LAN, it will open all of the files it intends to update in "shared"
mode. However, when RBBS-PC opens a file for READ access only, it
does NOT use DOS SHARE. This will on occasion cause sharing
violations when more than one node tries to read the same file at the
same time. To compensate for the problem, you should set the "read
only" attribute of any file which will NOT be updated during the
course of the call. Files such as WELCOME, PRELOG, all HELP, bulletin
and news files should be "read only."
(You change a file's read only status with the DOS utility ATTRIB.
The syntax is "ATTRIB +R (filename)." Please note that ATTRIB must be
located in the current search path, and the "+R" switch can be
reversed into "-R", when you want to remove a file's read only status
in order to edit it.)
We recommend setting the read only status on any file which you are
certain will not be updated (i.e. written back to).
SUMMARY
The hardest part about setting up RBBS-PC in a network environment is the
actual setup of the program for multi-node operation. But if you follow
certain guidelines (laid out for you in Appendix G), you should be fine.
