SERVICES(5) File Formats Manual SERVICES(5) NAME services -- service name data base DESCRIPTION The services file contains information regarding the known services available in the Internet. For each service a single line should be present with the following information: official service name port number protocol name aliases Items are separated by any number of blanks and/or tab characters. The port number and protocol name are considered a single item; a ``/'' is used to separate the port and protocol (e.g. ``512/tcp''). A ``#'' in- dicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Service names may contain any printable character other than a field delimiter, newline, or comment character. If "db" is specified as source in the nsswitch.conf(5), /var/db/services.db is searched. The database in /var/db/services.db needs to be updated with services_mkdb(8) after changes to the services file have been applied. NIS INTERACTION Access to the NIS services.byname map can be enabled by adding a single ``+'' on a line by itself in the /etc/services file. This causes the contents of the NIS services map to be inserted at the location where the ``+'' appears. FILES /etc/services The services file resides in /etc. SEE ALSO getservent(3), nsswitch.conf(5), services_mkdb(8) HISTORY The services file format appeared in 4.2BSD. BUGS A name server should be used instead of a static file. FreeBSD 13.2 April 4, 2010 SERVICES(5)
