Perhaps you should just buy a book? Something like Unix Network
Programming should have the above.
It will certainly have the much-more-recommended method of finding your
IP number, which is to find your hostname and then look it up. Both
methods will be lacking in some circumstances (think of machines with
more than one IP number for a trivial case).

If you remove ioctl(), how will you plan on maintaining compatibility
with other Unix systems?

That sounds pretty appropriate.
You know, I'd suggest virtually the same approach for a Windows install,
with much of the same reasoning.
Basically:
- Have C: be where Windows is installed, and, probably, applications.
- D: is where user data gets put.
This way, if the Registry gets so screwed up that you need to reinstall
Windows, there's at least a hope of keeping data on D: around.
I have gradually moved to using cfengine to set up increasing amounts
of my system configuration. <http://www.iu.hioslo.no/cfengine/> This
amounts to constructing scripts that dribble necessary configuration into
configuration files wherever they may be.
The result is that the control of configuration on my system is wandering
into /etc/cfengine. Net result is that when I install a new system,
an early thing I do is to install cfengine, and then run it on that set
of data, whether:
a) NFS mounted from another system,
b) Sitting on a floppy, or
c) Burnt onto a CDROM backup.
I run cfengine, and it copies some config files into place, and inserts
entries into others, as needed. The beauty of this is that this leads
towards a "self-configuring" system. I _wish_ cfengine was a tad
friendlier; it would be quite wonderful to have a GUIed front end to
help generate rule sets. It's still useful enough to be valuable...

it has to do with switching screen names.

When a program crashes, it produces a snapshot of the state it was in at the

Debugging/finding out why it crashed.
Using something like
file CORE
will tell you what program produced the CORE file.
And using
gdb (program_name> CORE
Will allow you to find out why it crashed (if you're into that kinda thing).

I agree on NFS or SMB being your solution. Is the server running AppleShare
6.x? That does SMB sharing pretty well, you just have to configure it right
on the server end.

Mostly any internal ISA or external modem will work. To be sure, don't

I've had a Supra Express internal ISA 33.6 and now a Zoom internal ISA

If you are using GNUtar there are several options to control which
files are archived, the best of which is "--listed-incremental
filename". If 'filename' does not exist, it is created and you
get a full backup. If it does exist, you get all files newer than
the last run and everything (including old files) under renamed
directories. Additional information is included in the archive to
optionally allow you to delete files during the restore that were
not present at the time the backup was taken (there is no way to
do this with cpio or non-GNU tar). The --listed-incremental file
is modified in place after an incremental run. If you want to base
all incrementals from the initial full, you should copy the file
before each incremental and replace it with the original afterwards.
If you want to create a 'chain' of incrementals that must be restored
in sequence, leave the modified file each time. A simple script
can do this, including mailing the output to the admin. Or, if you
have more than a few filesystems you might want to install the
free 'amanda' system that not only performs this scripting across
machines but also does the scheduling of full/incrementals to
match the tape space you have.

The recommended method is to not try to find your IP number. Programs that try
to discover the IP address of the local machine are kludgy, and will break
under circumstances that the author did not take into account: multiple
interfaces, IP aliasing, dynamic IP, etc.

Boy, I am really glad I kept up with this line of conversation because every
response has been very helpful and now yours, Chrisopher, has stepped, I think,
into an area that I ultimately was looking to get to. I am fairly new to Linux
and just started using it on my home PC recently. There is one hell of a lot of
files that make up this system. WHEW! Maybe 2% of all these files I feel
comfortable with. Out of all these files what do I backup and replace, after a
disaster or upgrade, to allow as much as possible returning to the same
configurations on everything as I had before? I want to get to that point as
quickly as possible before my configuration matures too much, you know what I
mean? This cfengine you speak of can help with that? I am definently interested
in knowing more. Thanks, I think, for bringing this up!!

It's been years since I've used one of these. A couple things occur though:
1. You say that the CT1810 card is set for IO address of 0x230 but you later
say that you've tried to load the module with "linux sbpcd=0x250,1". Why are
you using 250 here instead of 230?
2. The second parameter you mention (,1) represents the type of CD connected
where 0=LaserMate, 1=SB, 2=Soundscape, 3=Teac16bit. I remember having to cycle
through the CD types until I found one that worked.
