If you have a question about Linux you should get and read the Linux Frequently

Only if you have a posting that is not more appropriate for one of the other

In one of the HOWTO's, it mentions doing a

strings uugetty | grep "/etc/defaults"
|

to verify that you have the right version. I installed Slackware 2.0, and the

I have a Future Domain TMC-1660ER which I use with Windows NT and OS2
|

connected to access an IBM ( Toshiba ) CDROM drive. I recently
|

purchased the Yggdrasil Plug and Play package. On booting, the system
|

does not detect the SCSI interface. I have configureed the card to use
|
||||
the BIOS and also I have tried disabling the BIOS and booting linux with
|
||||
the
|
||||
|
||||
boot: linux tmc16xx=0xCA000,5
|
||||
|
||||
Is anyone else using this interface that could offer a suggestion. Any
|
||||
help would be much appreciated.

|

|

: Several solutions:

: - use xhfs to read data from Apple 1.44 MB HFS floppies (no write so far as

|

|

What we need to do is at least read Syquest 88MB cartridges written by a

MAC. xhfs only does floppies and, according to our Mac person, a PowerMac
|

will not write DOS format stuff on a Syquest (just on floppies). Can

anyone confirm this or offer an alternative? This just because real

just leased an imagesetter that will be connected to a Linux system.

|

|
||||
No, I did some testing, and argv[0] seems to always be the command name
|
||||
that is used to execute the command; if it is found by virtue of being
|
||||
in the user's search path, only the command name itself is there.
|
||||
|
||||
In shell scripts, however, $0 seems to be the full path to the script,
|
||||
or the path relative to the current directory when the script is started.
|
||||
It is easy enough for the script to tell which, by virtue of a leading /.
|
||||
|
||||
So a shell script wrapper can be used to tell your program where it lives,
|
||||
through environment variables, executing the real program using the full
|
||||
path (and thus passing argv[0] the way the original poster likes), or
|
||||
an extra argument.

|

Sorry if this is the wrong newsgroup, but I really don't know where to ask
|
||||
this one.
|
||||
|
||||
I just purchased a 486DX2-66 green motherboard. This is the kind of
|
||||
motherboard with the option to half the power to devices which are inactive
|
||||
after a certain period of time, and then reset the power consumption upon
|
||||
any sign of device activity.
|
||||
|
||||
I know that this works very well for DOS, which doesn't really care what is
|
||||
happening to the system it is on. I wonder though, will Linux react
|
||||
favourably to devices having their power cut in half, without raising a
|
||||
fuss? Since my systems are running 24 hours a day, I'd be interested in
|
||||
upgrading all of my systems to green motherboards, so long as Linux will
|
||||
handle them well.
|
||||
|
||||
At the same time, I don't want to cause problems by trying it. I've had
|
||||
unusual experiences with self-caching hard-drives hooked to Linux, and don't
|
||||
want to go through this again.
|
||||
|
||||
Anybody else have a green motherboard, with these options enabled?
|
||||
|
||||
Thanks for any information.

Matt, at least some versions of Perl can run suid scripts? How? By
|
||||
making /usr/bin/perl setuid root and have that binary handle the
|
||||
permissions/security stuff. This is THE RIGHT WAY to handle *any*
|
||||
language which securely can run setuid programs, and can be done on a
|
||||
language-by-language basis.

|

|

That also begs the question of whether or not your message was
|
||||
important enough to even care if you really wrote it or not.
|

Now maybe if you were my boss telling me to get ready and head

|

But I've seen nothing so far on the net (well over 10 years) where

it mattered who posted or not.

There is none up to now. A driver for the Specialix SI is in progress.

This has already been done several times, by utilizing the /proc
|
||||
filesystem (which is the only way to do it). Linus has rejected the
|
||||
patches every time.
|
||||
|
||||
*** Explanation for anyone who missed this thread last time ***
|
||||
|
||||
When the kernel detects a shell script (magic number "#!") it will do
|
||||
the usual checks for accessibility, then open the file to read the
|
||||
command processor. Then it exec's the *command processor* with the
|
||||
filename on the command line. The command processor than opens the
|
||||
file in user space: race condition.
|
||||
|
||||
The alternative proposed was passing the file argument as a file
|
||||
descriptor through the /proc filesystem; however, all of a sudden you
|
||||
have an essential kernel service *dependent* on having the /proc
|
||||
filesystem properly mounted; in fact, the patches I saw all hard-coded
|
||||
the name /proc and used it for all shell scripts. I am not too sure
|
||||
how well the system startup would have dealt with that.
|
||||
|
||||
However, once again I am saying that this is the Wrong Thing to do.
|
||||
The kernel should assign the new process with the privileges by the
|
||||
user and the *binary* executed, which is the command processor. If
|
||||
the command processor can handle setuid scripts, and the sysadmin
|
||||
wants to enable them, it should be run as setuid root and convey the
|
||||
privileges itself.
