Only one method is required to be called in the script extending the INET base class -- process_request. This method is called after the socket connection is established and the script is started by inetd. The script will have handle the client-server communication once the socket is established via calls to syswrite() and sysread(). It's also important to keep track of socket timeouts to prevent a denial of service attack:
local $SIG{ALRM} = sub { die "Timed out!\n" };
my $timeout = 30;
my $previous_alarm = alarm($timeout);
There are several other hook methods that are left undefined in the base class that can be implemented. These will be covered in the example code.
