Hi!

By the login.conf manpage, if I do this:


default:\
[...]
        :coredumpsize=0:\
[...]

It will forbid users from doing core dumps. Am I right?

If I am, why does this 'classless' user can do this:

bash-2.03$ cat > core.c
/* do a coredump */

int main( int argc, char** argv) {

int *i = 0;
i[0] = 1;

}
bash-2.03$ gcc core.c -o core
bash-2.03$ ./core 
Segmentation fault (core dumped)
bash-2.03$ ls -l core*
-rwxr-xr-x  1 marc  guest    3084 Sep 17 23:18 core
-rw-r--r--  1 marc  guest      82 Sep 17 23:18 core.c
-rw-------  1 marc  guest  266240 Sep 17 23:19 core.core
bash-2.03$ 

Why isn't it working?

If I'm wrong, how can I forbid users from making coredumps???

My searches on the mailing lists where unfortunatly vain.

Thanks, and by the way that 3.3 release is really a charm. (well at
least 3.3-stable.. :))

With XFree86 3.3.5, I'm in a dream... :)) I'm running:

FreeBSD freed.dyn.ez-ip.net 3.3-RC FreeBSD 3.3-RC #16: Fri Sep 10
21:09:10 EDT 1999
spidey@freed.dyn.ez-ip.net:/usr/src/sys/compile/HALL  i386

which.... hum... is supposed to be -stable, but I think is the
'pre-release' am I right? What is -RC?

thanks again for this incredible OS.

Ants.
