It seems you have limited the coredump size to 0, i.e., no core dumps will
|
|
be written. Say something like
|
|
|
|
limit coredumpsize unlimited
|
|
|
|
to enable coredumps. The exact command depends on the shell you're using.

One of Digi's employees is currently at work on a PC/Xe driver for Linux,

|
Date: 28 Sep 1994 11:24:47 GMT
|
|
|
|
Hi there!
|
|
|
|
I suudenly came up with a problem concerning mount/umount.
|
|
When a mount fails, it leaves a file /etc/mtab~ and with
|
|
this it prevents any other mount/umount command to run at all.
|
|
|
|
As I understand this is a kind of semaphore to avoid multiple
|
|
mounts to run the same time, at least in normal use.
|
|
|
|
But when I get something like "Device Busy..." or so,
|
|
I find out that, e.g. I didn't put a floppy to the drive or a typo,
|
|
and try again, then mount fails because of /etc/mtab~.
|
|
|
|
Is this a bug or a feature?
|

Hi,
|
|
|
|
I've been watching these discussions about ELF vs a.out with quite a
|
|
bit of interest. It looks, at least to me, like things will be moving
|
|
toward ELF. Who actually decides if this happens and if so when it
|
|
happens? What does Linus have to say about it? If this does take
|
|
place, does this mean that EVERYTHING must be recompiled for ELF? (I
|
|
understand that both formats will be supported, but, if we're moving
|
|
to ELF then I, personally, would want to use the 'preferred' medium)
|
|
Just how big is this project going to be if its implemented? It'd be
|
|
nice if the hard work that all the developers have done didn't have to
|
|
be recompiled or rewritten.

clock() displays the _processor time_ used by the program. This is
|
|
completely different from the real time of the system (try 'time -v ls'
|
|
or something from your prompt); try gettimeofday() for the accurate real
|
|
time...
|
|
|
|
By the way, this is a standard way of doing things, not a peculiarity
|
|
of Linux. From what I know, only MS-DOS displays the real time using
|
|
clock() (obviously since it's single-tasking...).

I'm looking on information about PCMCIA support for Linux.
|
|
|

I am mostly interested in network and modems,
|
|
|
|
Does anyone working on PCMCIA drivers for Linux?
|
|
|
|
=======
|
|
|
|
Second question is about S-VGA drivers, is there or will be a 'generic'
|
|
one supported in 640x480x256? or/and the LINEAR chips set.?
|
|
|
|
|

This is for a AST Advantage! Explorer Notebook, I've (mostly) converted

The way I understand it, having talked with some of the people involved
|
|
second hand. The DEC fellow has done/is doing his own port, while Linus
|
|
is working on something seperate. However some of this information is
|
|
second hand to me so accuracy may be somewhat lacking.

Well, I think there should be an locking mechanism included (like

Subject: [QUESTION] Linux terminal control

|
|
Hello all,
|
|
The school I work at is interested in getting linux installed. They
|
|
would like to be able to use it in CS classes if there is a way for the
|
|
instructor to access a students terminal (via ethernet or the student can be
|
|
logged into the instructors linux box), so the instructor can take over the
|
|
students terminal and help the student with programming or whatever
|
|
problems. After the instructor shows the student what is wrong, the
|
|
instructor turns the terminal back over to the student. Is there anything
|
|
like this out there? If so can it control a screen under dosemu? Please
|
|
reply with any information you may have via email or post.
|
|
|
|
Thank you,
|
|
Walt (muwt@uxa.ecn.bgu.edu)

ANY AND ALL INFORMATION/LEADS APPRECIATED!

I am working on a database and was intending to mmap the file as

PROT_READ | PROT_WRITE and MAP_FILE | MAP_SHARED. When experimenting
|
|
with this I found out that the Linux mmap doesn't allow PROT_WRITE

with MAP_SHARED. Can anyone tell me if this is planned to be added
|

soon? Any pointers on how to make it work? I just checked 1.1.51 and

it still seemed to not allow it.
|
|
|
|
Correct, Linux does not currently support a mmap() with PROT_WRITE +
|
|
MAP_SHARED. This is to be added after the release of 1.2.0, so 1.3.0
|
|
will have it definately. You can get around this by taking the file
|
|
descriptor from the mmap call and just before you would normally close
|
|
it, do a HUGE write() to the file descriptor. I had to do this to get
|
|
emacs to dump properly as an elf binary.

I have been currently looking for this package. But I remember seeing on

After isode 8.0 they went to IC (Isode Consortium) 1.0. And they are now

Hi all.
|
|
|
|
In a previous post to c.o.l.d./c.o.l.h. I wrote:
|
|
|
|
|... I upgraded: the kernel, the libraries, and the CPU. I bought
|
|
|an AMD DX2-66, and was happy about it.
|
|
|
|
|
|Then ... ftape began to bomb my system.
|
|
|I saw all sort of panics and reboots.
|
|
|
|
|
|Today I changed back the CPU to the original Intel DX-33...and ftape
|
|
|worked. No panics, no troubles.
|
|
|To be sure, I just reinstalled the DX2 CPU and retried the same backup
|
|
|on another tape. The system hung, and a disk went into standby mode.
|
|
| ...
|
|
|
|
Thanks to all people who replied.
|
|
|
|
Actually I am very sure of the software installation; due to the previous
|
|
experiences, I'm used to recompile the ftape module after EVERY kernel
|
|
change. I confirm that all worked fine with the 33-MHz CPU, no matter
|
|
which compiler/library I used.
|
|
|
|
Here are the news: now ftape works also with my 66-MHz CPU.
|
|
I suspect there is some critical timing parameter on my hardware
|
|
(motherboard, chipset, RAM, FD controller?), which is exposed by the
|
|
faster CPU. You can't be sure of these cheap Taiwan boards, even if they
|
|
are officially certified for 50 MHz operation.
|
|
|
|
The quality of the crashes seemed to suggest some disruption of the
|
|
instruction flow, maybe a wrong memory read. I wonder why only the ftape
|
|
module was affected.
|
|
|
|
Now for the solution:
|
|
After fiddling with the bus/RAM/cache parameters via the BIOS setup
|
|
with no success, I changed all references to inb() and outb() in
|
|
the file 'fdc-io.c' to inb_p() and outb_p(), so to slow down I/O
|
|
accesses via software. And this worked, at least for now.
|
|
|
|
Would someone please test this patch and see what happens? Actually
|
|
this should have no effect, but please check it and report any fault.

Subject: Smail Security Hole
|
|
Date: 28 Sep 1994 11:13:24 -0400
|
|
|
|
Someone posted modifications to the transports file so that a smail .forward
|
|
entry of /securityhole will be written using the user and group ids of
|
|
the owner of the .forward file.
|
|
|
|
This does not quite work as intended because /securityhole will still
|
|
be written even if the owner of the .forward file does not have
|
|
write permissions to the directory in question. (for instance /)
|
|
|
|
Once the file has been written, the user can then make it executable. For
|
|
instance a /bin/lc file could be created.
|
|
|
|
This is a serious security hole. Any SCO users out there? Do you find
|
|
yourself typing 'lc' instead of 'ls' much (as root)?
|
|
|
|
Any Linux system with this problem can be compromised.
|
|
|
|
A question : what are the implications of turning off smail's ability to
|
|
send mail to files? Or is that how it writes to mbox? What about the pipes
|
|
option? Can that safely be disabled?

How are you going to umount the disk if it's already been ejected? It seems
|
|
to me that this would rule out anything but read-only mounts.

|
|
|
|
Someone mailed me asking where exactly the hole should be plugged,
|
|
and I just saw an incorrect solution by Lee Silverman (no offense
|
|
intended), so here's how the file: transport should really look like:
|
|
|
|
file: driver=appendfile, return_path,
|
|
from, unix_from_hack, local; # or whatever
|
|
file=$user,
|
|
append_as_user, # essential
|
|
check_path, # _this_ was missing
|
|
expand_user,
|
|
suffix="\n",
|
|
mode=0644,
|
|
|
|
Without check_path, smail doesn't allow you to append to files
|
|
not owned by the user (append_as_user does that), but it allows
|
|
creation of new files in inaccessible directories. The original
|
|
warning posting said that :-)
|
|
|
|
The above config works for me (smail 3.1.28).
|
|
|
|
Followups are set out of .development.
|
|
|
|
bye
|
|
Patrick
|
|
|
|
P.S.: I still don't understand why check_path is not in the sample
|
|
configuration for the file: driver, but having it as an option
|
|
is useful since driver=appendfile can be used for other transports
|
|
(i.e. batched smtp)
