You have to setsid too, to disassociate from your parent's process group: #!/usr/bin/perl use strict; use warnings; use POSIX qw(setsid); # Become a daemon my $pid=fork; exit if $pid; # Parent exits here die "Couldn't fork $!" unless defined($pid); die "Couldn't start new session $!" unless POSIX::setsid(); # Do your daemon bit...

One solution is to fork and have the parent exit.	[reply]
