Perl Daemons and SIGHUPby explodec14 (Novice)
|on Feb 24, 2010 at 12:24 UTC||Need Help??|
explodec14 has asked for the
wisdom of the Perl Monks concerning the following question:
Hello -I have posted my problems in the chatterbox but i didn't get replies satisfying.
I have written a daemon (using Proc::Daemon:Init) which listens to port 9000 and forks whenever a client connects. So far so good. I have added signal handler in order to handle SIGHUP in case the user changes the configuration file and wants to reload the daemon. In this case, the daemon should restart itself in order to listen on the new configured port. The daemon traps the signal and when it tries to restart itself (using the exec call) it vanishes ...
I suspect it has to do with the daemonizing because otherwise I checked and it works fine.(a) Why is that ?
(b) What is the proper way to reload a daemon ?
(c) I have encountered in CPAN the package Daemon::Generic, which suggest somekind of solution, does anyonen know this package ?
10x in advance
