Everyone,
I would like to create a daemon server that could be used like sendmail,
dovecot etc. I would like it to monitor a specified port for queries
from a local network, and pass the queries to a database that is not
mysql or postgresql, and return the results to the same port,
I do not have experience in C so I would prefer to use perl.
Can anyone point me to a tutorial?
I don't have a tutorial but this should help:
# OK Here is were I need to daemonize this program. (NJC)
#
# * Open /dev/tty and use the the TIOCNOTTY ioctl on it. See tty(4)
# for details. Or better yet, you can just use the POSIX::setsid()
# function, so you don't have to worry about process groups.
# * Change directory to /
# * Background yourself like this:
setsid() || die "Can't start a new session: $!";
chdir("/");
fork && exit;
Then open your network ports and proceed to listen.
You might also want to use a search engine for "Perl daemon" you'll
find links like this:
