Kernel panic with kldload
I've been trying to make a little BSD sockets kernel loadable module thing.
(Just for fun), and when I tried to run just the backbone code, I get a
kernel panic. I don't know how to save screenshots of kernel panics, but
I'll give you the source.

too many kill()'s
The following source code:
#include stdio.h
#include signal.h
#include sys/types.h
#include sys/wait.h
#include sys/param.h
#include errno.h
extern int errno;
int main(int argc, char *argv[])
{
signal(SIGINT, SIG_IGN);
signal(SIGTERM, SIG_IGN);
if (!fork())
{
while(1) {
kill(getppid(), SIGTERM);
}
}
}
// End of source
when compiled and ran, makes my 4.7-release box quit EVERY SINGLE PROGRAM
(including boot-time daemons), and go into a fix-it shell.
My question is this: why does this happen? I can't seem to figure it out.
I've worked with many other people about this, and they don't seem to know.
(When you exit the fix-it shell, the computer finishes booting, it's like
going into single-user mode upon boot)
Run this code and see what happens (nothing bad, just wierd).

Samba and Win2k
I just got a samba server running on a FreeBSD box. Whenever trying to change the perm bits on a file from Win2k (Read-Only, Hidden, Archive), then click on the desktop, Explorer.exe crashes. Does anyone know why? Thanks, lattera To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
kppp
I run kppp for dialup. My modem is on port /dev/cuaa4. kppp doesn't allow me to use /dev/cuaa4, only up to /dev/cuaa3. Is there a way to force kppp to see /dev/cuaa4? I've currently removed /dev/cuaa3, and instead made /dev/cuaa3 a symlink to /dev/cuaa4.

Re: kppp
I determine that the modem is on /dev/cuaa4 by trying all ports up to that one. I did this: ppp ON localhost set device /dev/cuaa0 ppp ON localhost set speed 115200 ppp ON localhost term ppp now freezes ppp ON localhsot set device /dev/cuaa1 ppp ON locahlost set speed 115200 ppp ON localhost term ppp now freezes ppp ON localhost set device /dev/cuaa2 ppp ON localhost set speed 115200 ppp ON localhost term ppp now freezes ppp ON localhsot set device /dev/cuaa3 ppp ON locahlost set speed 115200 ppp ON localhost term ppp now freezes ppp ON localhsot set device /dev/cuaa4 ppp ON locahlost set speed 115200 ppp ON localhost term at OK atdt1234567 CONNECT ISP login:asdfadfadf --- That's how I got it lattera Nathan Kinkade writes: On Fri, Jan 10, 2003 at 08:25:53AM -0700, [EMAIL PROTECTED] wrote: I run kppp for dialup.

Older versions
I have a VERY, VERY old laptop (1.9 Megs of memory IBM), and I was wondering if I could get FreeBSD 1 for it. If so, where? Thanks! lattera To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
