Just like in the Dilbert cartoon. Someone (dogbert?) predicts this
device and then says that engineers will go around twiddling there
finger even when not in from of a computer.
Next frame: Two finger twiddlers meet. "Hi. You're an engineer,
too?" "No, I'm just spastic."
Does this count as prior art?

Subject: Look for a driver to manage mailbox shared m�mory on ISA bus
Date: 5 Feb 1999 15:47:57 GMT
Hello.
I'm french ingeneer and I'm working on industrial computers.
For an application, I use an embeded board in PC on ISA bus. This board is able
to manage a FIP net. The software on this board already exists and works under
OS/9 operating system. I don't want to modify it.
I choose to use linux as operating syst�m on PC. So, I need a Linux driver to
manage mailbox on shared memory on ISA bus.
Could you help me? Could you say me where I can find a C source on the net of a
driver that approach my need or better, could you send me an example of this
kind of driver by mail. I'll arrange it for my personnal use. I'll give it
again under GPL.
Thanks for all.
Gilles.

Subject: Re: Using message queues from kernel land, and other stuff...
Date: Fri, 5 Feb 1999 10:50:16 -0600
I am devloping under 2.0.35, but I have implemented a IPC message queue
between kernel code and a user application. Note, this is one-way (kernel ->
user) only. You really can't do it the other way since you don't want to be
pending the kernel on some message queue from userland. I use IOCTL's and
get_user() calls to retrieve data from userspace.
The user application creates the queue with:
msgid = msgget(MSG_QUEUE_ID, 0666 | IPC_CREAT)
and pends on the queue using:
ret_val = msgrcv(msgid, ð_frame, sizeof(struct eth_msg), 0, 0)
I attach to the message queue in the kernel with:
msgid = sys_msgget(MSG_QUEUE_ID, 0666 | IPC_CREAT)
I send messages into the queue from the kernel by:
sys_msgsnd(msgid, eth_frame, sizeof(struct eth_msg), 0)
I don't have any problems with moving up to 8Mbits of information through
this method. If I am running X simultaneously and jerking around with it, I
do see some overflows when using the OS defaults for IPC message queues.

Are terminals, like ttyp0, managed by the kernel? Is there a common
device driver which programs like xterm and telnetd use or do they all
have their own?

The document is OK, with a few small technical errors. Overall, though,
I think it was good, at least for beginners and I learned stuff I didn't
know %). The author was notified of the errors.

This is your problem ------------------|
You're trying to compile a C++ program (iostream.h) with the C compiler
(stdio.h)
Try changing the gcc to g++ (and reverting back to #include
<iostream.h>)

RHIDE is very close to the Borland IDE. Unfortunately it only runs in the
console. XWPE is also very much like the Borland IDE, if not as close a

I am developing a system app that will be running with root priviledges
and will take requests over a socket. Based on a supplies user ID, and
password I would like to do a setuid to the user to process the request.
How can I validate ( encrypt ) the supplied clear text password to
compare it with that returned by getpwent(). Can a root process do this
encryption ?
Any help will be greatly appreciated.

Are you sure that was NT and not the other Windows? NT locks 12MB of
RAM for the kernel. Or am I wrong?

It is interseting, I tried it at work with a PS/2 and a serial mouse over
the background with Windows NT Workstation 4.0 and SP4 at work today.
All I had to do was hold the either the left of right mouse button down
while the cursor was over the background and 100% CPU load was achieved!
No frantic moving of the mouse needed. To be sure I took the ball out
and tried again with the same result.
More interesting is that holding the middle mouse button has no effect.
For the record they were both Logitech Pilot mice with three buttons,
needed for a Windows ported Unix application that is clumbersome to
use with two buttons.
However it might make it easier to crash NT systems on demand which is
a *good thing*, "Look at this all I have to do is wikkle the mouse about a
bit while doing X and it crashes, what you need is Linux".
