DESCRIPTION

Working with named services can be a pain when you want to go back and forth between the port and its real name. This module helps alleviate some of those pain points by defining some helping hashes, functions, and regular expressions.

CONSTANTS

$IANA_REGEX_PORTS

Regular expression to match any port, irregardless of which protocol it goes over.

While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience.

Case is ignored and the protocol must match on a word boundary!

Examples

    # Matches
    $port =~ $IANA_REGEX_PORTS;

    # Won't match
    $non_port =~ $IANA_REGEX_PORTS;

$IANA_REGEX_SERVICES

Regular expression to match any service, irregardless of which protocol it goes over.

While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience.

Case is ignored and the protocol must match on a word boundary!

Examples

    # Matches
    $service =~ $IANA_REGEX_SERVICES;

    # Won't match
    $non_service =~ $IANA_REGEX_SERVICES;

$IANA_REGEX_PORTS_DCCP

Regular expression to match any port that is known to work over dccp.

While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience.

Case is ignored and the protocol must match on a word boundary!

Examples

    # Matches
    $port_dccp =~ $IANA_REGEX_PORTS_DCCP;

    $non_port_dccp =~ $IANA_REGEX_PORTS_DCCP;

$IANA_REGEX_PORTS_SCTP

$IANA_HASH_INFO_FOR_SERVICE

This maps a service and a protocol to the information provided to us by IANA.

Examples

    #  Get info for ssh over tcp
    $ssh_tcp_info = $IANA_HASH_INFO_FOR_SERVICE->{ ssh }{ tcp };

    Dumper $ssh_tcp_info;
    #   22 => {

    #      name => 'ssh'
    #      note => 'Defined TXT keys: u=<username> p=<password>'
    #   }


    #  Get info for http over any protocol
    $http_info = $IANA_HASH_INFO_FOR_SERVICE->{ http };

    Dumper $http_info;
    #   sctp => {
    #       '80' => {
    #           desc => 'HTTP',
    #           name => 'http',
    #           note => 'Defined TXT keys => 'u=<username> p=<password> path=<path to document>',
    #       },
    #   },
    #   tcp => {
    #       '80' => {
    #           desc => 'World Wide Web HTTP',
    #           name => 'http',
    #           note => 'Defined TXT keys: u=<username> p=<password> path=<path to document>',
    #       },
    #   },
    #   udp => {
    #       '80' => {
    #           desc => 'World Wide Web HTTP',
    #           name => 'http',
    #           note => 'Defined TXT keys: u=<username> p=<password> path=<path to document>',
    #       },
    #   },

$IANA_HASH_SERVICES_FOR_PORT

This lists all of the services for the given port, irregardless of the protocol.

An empty list will be returned if nothing is found. This respects wantarray>

Examples

    my $port_22 = $IANA_HASH_SERVICES_FOR_PORT->{ 22 };
    Dumper $port_22;
    # [qw/ ssh /];

    my $port_1110 = $IANA_HASH_SERVICES_FOR_PORT->{ 1110 };
    Dumper $port_1110;
    # [qw/ nfsd-keepalive  webadmstart /]

$IANA_HASH_SERVICES_FOR_PORT_PROTO

This lists all of the services for the given port and protocol.

Examples

    my $port_22 = $IANA_HASH_SERVICES_FOR_PORT->{ 22 }{ tcp };
    Dumper $port_22;
    # [qw/ ssh /];

    my $port_tcp_1110 = $IANA_HASH_SERVICES_FOR_PORT->{ 1110 }{ tcp };
    Dumper $port_tcp_1110;
    # [qw/ webadmstart /]

    my $port_udp_1110 = $IANA_HASH_SERVICES_FOR_PORT->{ 1110 }{ udp };
    Dumper $port_udp_1110;
    # [qw/ nfsd-keepalive /]

$IANA_HASH_PORTS_FOR_SERVICE

This lists all of the ports for the given service, irregardless of the protocol.

Example

    my $service_http_alt = $IANA_HASH_PORTS_FOR_SERVICE->{ 'http-alt' };
    Dumper $service_http_alt;
    # [qw/ 591  8008  8080 /];

METHODS

iana_has_port

Helper function to check if the given port (and optional protocol) is defined by IANA.

If only the port is given, then it will be checked across all protocols while restricting the search to just the provided protocol if one is given.

Arguments

Port
- Required
- Port (int)
- Port you want looked up
Protocol
- Optional
- String
- Limit the search to only this protocol if specified

Returns

Search results
- Boolean
- 1 if the match was found, 0 otherwise

Examples

    iana_has_port( 22 );    # 1
    iana_has_port( 34221 ); # 0

    iana_has_port( 271, 'tcp' );  # 1
    iana_has_port( 271, 'udp' );  # 0

iana_has_service

Helper function to check if the given service (and optional protocol) is defined by IANA.

If only the service name is given, then it will be checked across all protocols while restricting the search to just the provided protocol if one is given.

Arguments

Service Name
- Required
- String
- Service name you want looked up
Protocol
- Optional
- String
- Limit the search to only this protocol if specified

Returns

Search results
- Boolean
- 1 if the match was found, 0 otherwise

Examples

    iana_has_service( 'ssh' );    # 1
    iana_has_service( 'not-ss' ); # 0

    iana_has_service( 'xmpp-server', 'tcp' );  # 1
    iana_has_service( 'xmpp-server', 'udp' );  # 0

iana_info_for_port

Helper function to get the known services for the given port and optional protocol, as defined by IANA.

If only the port is given, then you will get back an array ref containing all of the services that are defined by IANA. If a protocol is specified, then the returned prtocols will be limited to those running over that type.

Arguments

Port
- Required
- Port (int)
- Port you want looked up
Protocol
- Optional
- String
- Limit the search to only this protocol if specified

Returns

Search results
- Array
- The list of protocols running over the specified info (arrayref if in scalar context)

Examples

    iana_info_for_port( 22 );    # [qw/ ssh /]
    iana_info_for_port( 34221 ); # []

    iana_info_for_port( 271, 'tcp' );  # [qw/ pt-tls /]
    iana_info_for_port( 271, 'udp' );  # []

iana_info_for_service

Helper function to get the known information for the given service and optional protocol, as defined by IANA.

If only the service is given, then you will get back a hash ref containing the normal return information hash for each defined protocol for that service.

Arguments

Service Name
- Required
- String
- Service name you want looked up
Protocol
- Optional
- String
- Limit the search to only this protocol if specified

Returns

Service information (for a provided protocol)
- Hash
- Undefined if the searched was unsuccessful!
The returned hash contains the following pieces of information (keys are lower case):

Name

The full name (with proper capitalization) for the requested service

Desc

A short synopsis of the service, usually a sentence or two long

Note

Any additional information they wanted to provided that users should be aware of

Examples

    iana_info_for_service( 'xribs' );  # { udp => { 2025 => { desc => '', name => 'xribs', note => '' } } }
    iana_info_for_service( 'not-ss' ); # undef

    iana_info_for_service( 'xribs', 'tcp' );  # undef
    iana_info_for_service( 'xribs', 'udp' );  # { 2025 => { desc => '', name => 'xribs', note => '' } }
