3.6. Adding a New Service (inetd)
Problem
You want to add a new network service, controlled by inetd .
Solution
Add a new line to /etc/inetd.conf of the form:
SERVICE_NAME SOCKET_TYPE PROTOCOL THREADING USER /PATH/TO/SERVER ARGSThen signal inetd to reread /etc/inetd.conf. [Recipe 3.4]
Discussion
The values on the line are:
Service name. A service listed in /etc/services . If it’s not, add an entry by selecting a service name, port number, and protocol. See services(5).
Socket type . Either
stream,dgram,raw,rdm, orseqpacket.Protocol. Typically
tcporudp.Threading . Use
waitfor single-threaded, ornowaitfor multithreaded.User . The service will run as this user.
Path to server executable.
Server arguments , separated by whitespace. You must begin with the zeroth argument, the server’s basename itself. For example, for /usr/sbin/in.telnetd, the zeroth argument would be in.telnetd.
A full example is:
telnet stream tcp nowait root /usr/sbin/in.telnetd in.telnetd
A line in inetd.conf may contain a few other details as well, specifying buffer sizes, a local host address for listening, and so forth. See the manpage.
