services Database

The services database lists the names of TCP and UDP services and their wellknown port numbers; it is used by programs that call network services. The Solaris installation automatically creates the services database; it generally requires no administrative handling.

The services(4) man page contains complete syntax information. An excerpt from a typical /etc/inet/services file is shown below.

Example 7-10 /etc/inet/services File
