The minnotify program

minnotify reads arguments on its command line and prints them on fd 7, in a form that is readable by minnotifyd. It then reads minnotifyd's answer on fd 6, and exits.

Interface

     minnotify ipcontact portcontact ipok proto data

• ipcontact and ipok are IP addresses of the form a.b.c.d. portcontact is a number between 0 and 65535. protocol and data are strings.
• minnotify exits 100 if it finds an error in the arguments, 111 if there is a hard error, 0 if the notification succeeded, 99 if the notification failed temporarily, and 1 if the notification failed permanently.

The signification is: A client at adress ipok may perform a TCP connection at address ipcontact and port portcontact, using protocol proto, and ask for data.

The interpretation of these values are up to the application program run by minnotifyd.

Common use

minnotify does not contact the network itself. If you want to use it to send a notification message to some minnotifyd program listening somewhere over the network, use minnotify with a UCSPI client tool such as tcpclient. For instance, the command line

     tcpclient host port minnotify ipcontact portcontact ipok proto data

should do what you want.
