Net::servent (Perl in a Nutshell, 2nd Edition)

8.162. Net::servent

Returns information for an Internet service. Overrides the core getservent, getservbyname, and getservbyport functions, replacing them with versions that return Net::servent objects. The functions take a default second argument of tcp. The objects have methods that return the fields of the same name from the servent structure in netdb.h:

Field	Description
`aliases`	List of aliases
`name`	Name of service
`port`	Port
`proto`	Protocol to use

You can access the structure fields with the methods or by importing the fields into your namespace with the :FIELDS import tag and accessing them by prepending s_ to the field name:

$serv_obj->name( )
$s_name
