SCO UnixWare 7/OpenUNIX 8/OpenServer 6 FAQ : Networking :
What are network services? |
| A Uw7/OSR6 system runs many programs in the background that are designed to respond to and communicate with a user's program. This is called the server/client model. We refer to a server process as a service, which waits for communication on one or more ports. People are familiar with such services as ftp, and telnet. These are offered by the corresponding processes ftpd, telnetd, and httpd on ports 21, 23, and 80. These services are mapped out in a text file called /etc/services.
