Hello,
can anyone, please, point out a C skeleton for FreeBSD daemon.
Is the following simple example correct for FreeBSD?
if (getppid() != 1)
{
signal(SIGTTOU, SIG_IGN);
signal(SIGTTIN, SIG_IGN);
signal(SIGTSTP, SIG_IGN);
if (fork() != 0)
exit(0);
setsid();
}

Take a look at src/lib/libc/gen/daemon.c, man 3 daemon

Hi all,
just like many people, I want to run my dangerous daemons as a
non-root user in a chroot environment. Now, I would usually use the
``su'', or ``chroot'' tools from the FreeBSD toolset in the creation
of an rc.d script, but the question that puzzles me is how to combine
these two
Hi hackers,
Is there a way to read user-land environ(7) table from the kernel for a
given process ?
Cheers,

Does 'ps -auxwwwe' do what you want?

Hi,
Is there a way to read user-land environ(7) table from the kernel for a
given process ?
You have to look at the proc structure for a process and there you will
find a buffer for the 'ps_strings' and a few offset variables to show where
the environment variables are.

Unfortunately, some changes in the lpd code that happened last year (as
far as I remember) are very disadvantageous for the operation of our
(heavily loaded) printer server which is based on FreeBSD for years now.

Hi Terry (and others!)
You seem to know a lot about the kernel (as you always expand on my
Cliff Notes versions of my answers). Can you give me any hints on
the device driver question I posted a few days ago. There was a
response, however I don't see how it applies for these reasons.
1.
Also have a look at jail(8).

Well, I'm willing to see what we can
ipfw seems to be confused about where to forward packets if no
interface is specifically mentioned. Before I file a PR
on it, I'd like someone who is more familiar with how ipfw
operates to quickly look over my findings.

I cannt reproduce it. Whats the version of the NetBSD box on other side?

Okay after bashing my skull against this problem for some time now, I've
narrowed this problem down. What Im attempting to do is get a signal from the
bktr driver after each frame is posted. The code in the kernel supports this.
It even works for some output formats. The problem is the driver
