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 either with the methods or by
importing the fields into your namespace with the :FIELDS import tag and
then accessing them by prepending s_ to the field name:
$serv_obj->name() $s_name
