NAME
services —
service name data
base
DESCRIPTION
The
services file contains information regarding the known
services available in the DARPA 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
slash (“/”) is used to separate the port and protocol (e.g.
“512/tcp”). A hash (“#”) indicates 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.
The database in
/var/db/services.db needs to be updated with
services_mkdb(8) after
changes to the services file have been applied.
FILES
- /etc/services
- The services file resides in
/etc.
SEE ALSO

HISTORY
The
services file format appeared in
4.2BSD.
BUGS
A name server should be used instead of a static file.
