Actually, the sudo utility would be closer to what he describes. It seems to
have disappeared from RedHat distros for some reason. Sudo lets you delegate
the running of specific privileged commands to non-privileged users.

It's to gcc's credit that it *doesn't* handcuff you into ansifying
everything under the sun. Rogue (_real_ rogue, not any of the
cheesy imitations out there) from 1981, when ANSI C wasn't even a
cloud on the horizon, is compilable with gcc even today.

Hi,
is there a version of apmd out there that will run a script upon

doesn't respond well to s/r, e.g. the ESS Maestro sound board on some

There are several RPM related projects but I have yet to find one that
helps answer the following question:
"Where and how do I find and get the rpms to bring my system, as
installed, uptodate?"
I would really like to be able to set a list of "trusted" repositories
(such as updates.redhat.com, etc.) and a utility that would check my
current version, dependencies, etc. and determine, and get the rpms I
needed to bring it up-to-date.

from teh comand line try:
stty < /dev/ttySx
man stty will tell you want you can do with it.
you can set baudrate and handshaking
stty clocal speed 4800 < /dev/ttyS0
will set in/out baudrate at 4800 for serial port /dev/ttyS0 with no

There is one, Micro$oft NetShow 2.0 for Linux. When I tried it it

Putting a law on the books doesn't mean anyone _cares_ about that law.
I'll reverse-engineer as much as I want. If I sell something based on
directly-lifted code, I would expect to be procescuted, otherwise I
expect to be left alone.
It's like radar detectors-once them radar beamies are in my airspace,

Silly question - which country does this law exist? I'm UK based...is this
a UK issue? Or is it stateside ?
This is certainly an intriguing act - has it been tested in a real case
yet or is it just there waiting for the lawyers to pounce ?

Does it also mean that if you modify Windows95 to the point that you
purge out all the crap that isn't needed and afterwards it doesn't

I take it the answer to your thread yesterday is that
file->f_dentry->d_inode is indeed the inode of the file itself? This
would only make sense because a file can have more than 1 path entry

My printer is a Brother MFC7000FC - yes I kicked myself for not choosing

Anyway none of the drivers I choose seem to be compatible

OK, would you rather have them spend this fixed amount of resources
doing one driver right or 20 different versions because the
operating systems designers refuse to agree on a way to talk
to devices?

And the point to note here is that Mr. Becker is very unusual - and

And if none of them want to write the thing you need, there is
no way to encourage them. If there were, we might have an NFS
that intoperates with others, DVD drivers, full USB support and
so on. As it is, the best you can do is try to put all your
devices on the other end of an ethernet and try to use the
network interfaces as the 'standard' device layer to hide
your netapp, terminal server, X display, etc. instead of waiting
for native Linux support to match the hardware you can buy.
>Mr. Becker is doing an excellent job. And then when you consider
>just how much he has done ... whew!
But look through the changelogs if you think everything was right
the first time. While the hardware vendors may use a less experienced
software engineer they do generally pay someone to put in some
time testing before a release. As I recall, the early intel 10/100
drivers would lock up about daily and there may have been SMP problems
until fairly recently. (Not to be critical here, but maybe this really
is more than a one-man job...).
On the other hand I don't have much hope for any unix vendors to
ever agree on anything, and it isn't really going to help unless
you can binary-translate an NT driver. Back in the wierd time
that Novell owned SysV unix, they proposed making their Netware
drivers the binary standard for unix because they already had
them for most hardware of that era. But nothing came of it
then either.

Subject: Linux parport question
Date: Fri, 10 Sep 1999 23:27:42 +0200
Hi,
I'm a C newbie and want to use the linux parport code as a learning
project (so that I can understand the code for my WebCam II camera ;)
For a strange reason my code currently only works as a module? %-)
First the code:
================
#include <linux/kernel.h> /* We're doing kernel work */
#include <linux/module.h> /* Specifically, a module */
#include <linux/parport.h>
/* Deal with CONFIG_MODVERSIONS */
#if CONFIG_MODVERSIONS==1
#define MODVERSIONS
#include <linux/modversions.h>
#endif
int detect_device (void);
/* Initialize the module */
int init_module()
{
int res;
printk("Test, version 1, loaded succesfully\n");
res = detect_device();
/* If we return a non zero value, it means that
* init_module failed and the kernel module
* can't be loaded */
return 0;
}
int detect_device ()
{
struct my_port
{
char *name;
};
struct my_port *this_port;
struct pardevice res;
struct parport *port;
for (port = parport_enumerate (); port != NULL; port =
port->next) {
/* Try to detect a device on the port... */
printk("Port: %s\n",port->name);
}
res = parport_register_device(port,"bas",NULL,NULL,NULL,0,this_port);
return 0;
}
================
Without the parport..device part it works OK. I see parport0 in syslog.
But when i compile this code:
gcc -Wall -DMODULE -D__KERNEL__ -DLINUX -D__SMP__ -c start.c
start.c: In function `detect_device':
start.c:60: incompatible types in assignment
make: *** [start.o] Error 1
>From parport.h:
/* parport_register_device declares that a device is connected to a
port, and
* tells the kernel all it needs to know.
* pf is the preemption function (may be NULL for no callback)
* kf is the wake-up function (may be NULL for no callback)
* irq_func is the interrupt handler (may be NULL for no interrupts)
* handle is a user pointer that gets handed to callback functions.
*/
struct pardevice *parport_register_device(struct parport *port,
const char *name,
int (*pf)(void *), void (*kf)(void *),
void (*irq_func)(int, void *, struct pt_regs
*),
int flags, void *handle);
I'm pretty sure the problem is the *handle. The
http://www.cyberelk.demon.co.uk/parport/khg-parport.html page says:
The handle is just a pointer to whatever driver-specific structure you
want to associate with your device on that port.
What am I dowing wrong??
Thanx a lot

else /usr/sbin/klogd
