The in.aspd service (called by inetd) is deactivated by default. To activate
it, execute, as root,

$ update-inetd --enable asp

Be aware that this may be a security risk. You are recommended to firewall
off the asp port (27374/udp) from remote machines using (e.g.) ipchains
or iptables.


asp(1) can be used from scripts, a few examples: 

$ number="`192.168.1.1-5 | asp -f plato`"
$ echo $?
0
$ echo $number
192.168.1.1   

$ number="`echo 2.2.2.2 | asp -f plato`"
$ echo $?
1
$ echo $number

$ # no match
