[Eug-lug] Re: Wrapping

[John Sechrest]

Specifically, to work out what larry is saying, let's go thru 
a example that I have often used.

Suppose that I want to have a network service that creates fortune
quotes. Everytime I connect to the port, I get a new quote. 

There already exists a program that generates quotes, it is 
called fortune. I run the program, it generates a quote to 
standard out.

By creating an entry in /etc/inetd.conf or in /etc/xinetd.d
depending on which version, this program "fortune" can be 
wrapped by inetd, such that the programs services becomes a 
network service. 

# /etc/inetd.conf:  see inetd(8) for further informations.


# <service_name> <sock_type> <proto> <flags> <user> <server_path> <args>
fortune 	stream	tcp	wait	fortune	/usr/games/fortune fortune
