TCP and UDP port numbers (/etc/services) quick reference

Whilst the IP address provides the connection to the correct machine, it cannot distinguish the different service that is required. The port is used to distinguish the application. It is a value from 0 to 65535. The combination of IP address, port and protocol is called a socket, and has to be unique for every service. The port numbers area available for both TCP and UDP, and when referred to in conjunction with the IP address it specifies the "socket".

The first 1000 ports are reserved for specific applications, and on Linux can normally own be used by a daemon / application that has super user privileges. These are referred to as well known ports. Some are defined in RFC 1340, and more are defined by IANA.

Details of the reserved ports are listed on most systems in the /etc/services file, an example of which is shown below (taken from a Ubuntu Linux distribution).

/etc/services



# Network services, Internet style

#

# Note that it is presently the policy of IANA to assign a single well-known

# port number for both TCP and UDP; hence, officially ports have two entries

# even if the protocol doesn't support UDP operations.

#

# Updated from http://www.iana.org/assignments/port-numbers and other

# sources like http://www.freebsd.org/cgi/cvsweb.cgi/src/etc/services .

# New ports will be added on request if they have been officially assigned

# by IANA and used in the real-world or are needed by a debian package.

# If you need a huge list of used numbers please install the nmap package.
