NAME

       "socket_getaddrinfo" - command-line tool to "getaddrinfo(3)" resolver

SYNOPSIS

       socket_getaddrinfo [options...] host service

DESCRIPTION

       This tool provides a convenient command-line wrapper around the getaddrinfo(3) resolver
       function. It will perform a single lookup and print the returned results in a human-
       readable form. This is mainly useful when debugging address resolution problems, because
       it allows inspection of the getaddrinfo(3) behaviour itself, outside of any real program
       that is trying to use it.

OPTIONS

       --host, -H HOST
               Hostname to resolve. If not supplied, will use the first positional argument

       --service, -S SERVICE
               Service name or port number to resolve. If not supplied, will use the second
               positional argument.

       -4      Restrict to just "AF_INET" (IPv4) results

       -6      Restrict to just "AF_INET6" (IPv6) results

       --stream
               Restrict to just "SOCK_STREAM" results

       --dgram Restrict to just "SOCK_DGRAM" results

       --proto PROTO
               Restrict to just results of the given IP protocol

       --passive
               Set the "AI_PASSIVE" hint; results will used to bind() and listen() rather than
               connect()

       --canonical
               Retrive the canonical name for the requested host

       --help  Display a help summary and exit

OUTPUT FORMAT

       Each line of output will be given in a form that indicates the four result fields of
       "ai_family", "ai_socktype", "ai_protocol" and "ai_addr". The first three are printed in
       the form of a socket(2) call, either symbolically or numerically, and the latter is
       printed as a plain string following it. For example

        socket(AF_INET , SOCK_STREAM, IPPROTO_TCP) + '127.0.0.1:80'

NOTE

       Upstream this script is known as "getaddrinfo", but was renamed on Debian.
