Trying to use relaydelay.pl from projects.puremagic.com (greylisting
milter for sendmail)
End result is a perl file... and I want to invoke it as a daemon -
detached from any terminal.
it appears that most of the sysv scripts use /etc/rc.d/init.d/functions
to get a more sophisticated box of tools...
my problem is that my sysv script (called relay) hangs at the point
where it wants to initlog -q -c /usr/local/sbin/relaydelay.pl and
this obviously comes from the code in /etc/rc.d/init.d/functions. If I
kill the neverending process...everything is fine and the program is
launched BUT - it never detaches from the terminal. i.e.
#service relay start
then from another terminal (cuz this one never let's go)
#ps aux|grep relay
root 26576 0.0 0.1 2120 932 pts/4 S 00:28
0:00 /bin/sh /sbin/service relay start
root 26579 0.0 0.2 4456 1208 pts/4 S 00:28
0:00 /bin/sh /etc/init.d/relay start
root 26582 0.0 0.1 3784 676 pts/4 S 00:28 0:00 initlog -
q -c /usr/local/sbin/relaydelay.pl
root 26583 0.2 1.2 31004 6408 pts/4 S 00:28
0:00 /usr/bin/perl -w /usr/local/sbin/relaydelay.pl
root 26602 0.0 0.0 1620 472 pts/3 S 00:30 0:00 grep
relay
note that process is still listed in pts/4 (and I have switched to pts/3
cause pts/4 is otherwise occupied)
# kill 26582
# ps aux|grep relay
root 26583 0.1 1.2 31004 6412 pts/4 S 00:28
0:00 /usr/bin/perl -w /usr/local/sbin/relaydelay.pl
root 26613 0.0 0.0 1612 472 pts/3 S 00:32 0:00 grep
relay
I just want it to detach from the terminal (which is apparently the
entire point of /etc/rc.d/init.d/functions
Can someone direct me on this as I don't get it.
The entire contents of /etc/rc.d/init.d/relay
