My definition of getopt() has it operating in the context of the command to
parse the **argv - but I admit that my phrasing was misleading. My point was
that the shell passes the command string with minimal changes.

That is the advantage of the library approach - if an application needs a
token, it can get it, by overriding default behaviour. N.b. '*' is as likely
a token as '^E'.

I would like to see something seamless, so that if you change the default in
the 'shell' (I am using the Unix term here) it will automatically change the
_default_ behaviour of the application. The application will always have the
right to override any defaults for it's own needs.

Subject: HDS viewstation x-terminal/bootp?
Date: Mon, 12 Apr 1999 21:13:41 GMT
I recently acquired a HDS ViewStation X-terminal (thin-client) from a pile of
stuff that was going to be thrown out. I'm trying to use it as a X-server to
run stuff off my Linux box, but I'm not sure how. When I boot it up it sends
bootp requests (I guess they're broadcast on the network mask spec'd on the
x-terminal). It also tries to TFTP, FTP, or NFS connect to a remote machine
(also specified in the x-terminal OS or bios or whatever) to get config
files. However, at this point, it seems to be looking for proprietary
software that is downloaded to the local PROM's or something.
So, I have a couple questions:
1. What services does bootp provide? Where can I get the source code
to compile and use the bootp daemon on my Linux machine?
2. Has anyone had experience with this type of X-terminal or setting
up any X-terminal?
3. How does XDM fit into all of this?
Please let me know if anyone has answers, or if there is a site that has help
on this stuff. I've been looking all over, but can't seem to find anything
too specific.
Thanks,
Saksiri

Has anyone had any succesfull experiences running Linux on Compaq
Proliant3000 machines?
Specificaly with dual PII 300Mhz, 512MB ram, Smart 2dh raid controller?
As usual, compaq was less than usefull when asking them about their
"Linux ready" systems. From what I've been able to find in supported
Hardware lists there haven't been any mentions about any of Compaq's
smart raid controllers.
Please reply by e-mail as well as posting.

My first reaction would be that the programmer had been sloppy about writing
the name of one variable two different ways. In C, the programmer would have
gotten into the habit of writing myfilename, leaving his shift key for
#define's.

Why should case-sensitive passwords mean that file names should be case
sensitive? (I don't like case-sensitive passwords, incidentally. If you want
a safe password, add more characters, and randomise them. Getting a
case-sensitive password given to you over the phone is a nightmare that I
have experienced. The workaround tends to be to write the password down. It
is much easier to remember "mynoncasesensitive33pass9word" than
"mYpAsswOrD".)

I can't imagine any circumstances in which I could possibly want such a
thing. I can, I'm afraid, imagine circumstances where I would accidentally
create two such files, and then perform operations or edits on the wrong one,
and end up totally confused. That is why in practice most people do what has
been recommended earlier on this thread - use exclusively lowercase (and
hence less readable) names, reserving uppercase for special purpose files and
commands, if at all.
> You should tell the computer what to do and how to do it, not
> the other way around.
What I want is to have my file appear as MyFirstProgram.java, because that is
more readable. I don't want to type it that way because it is extra work - I
want to enter "myfi*" in a dialog box, or "myfi[TAB]" and have the name
completed. I cannot do this in Unix - it will not recognise any connection
between MyFileName and myfilename. It would be dangerous if the shell did any
such thing, as the fundamental error is in the file system. N.b. this is a
case of the computer telling me what to do and how to do it. A
case-preserving system allows me to name a file anything I want, and then
cease to worry about what exactly I called it.

More likly your program, try using gdb on the core dump and compile with

1. How to determine what the current hdparm rating is
Just trigger
>hdparm -gt /dev/your-device
from root.
It seems that if the -T flag is also specified, then a correction
factor based on the outcome of -T is incorporated into the result
reported for the -t operation. So you may want to trigger -gtT,
instead of -gt, for a slightly more accurate test.
The test is triggered on the device, not on single partitions.

MMmhhhh. It seems like your program has trashed the memory managed by
malloc (the heap). Try to use a memory checker to verify this
