NAME

       "socket_getnameinfo" - command-line tool to "getnameinfo(3)" resolver

SYNOPSIS

       socket_getnameinfo [options...] address port

DESCRIPTION

       This tool provides a convenient command-line wrapper around the getnameinfo(3) resolver
       function. It will perform a single reverse lookup to convert an address and port number
       into its host and service names. This is mainly useful when debugging names resolution
       problems, because it allows inspection of the getnameinfo(3) behaviour itself, outside of
       any real program that is trying to use it.

OPTIONS

       --address, -A ADDR
               Numerical form of address to look up. If not supplied, will use the first
               positional argument.

       --port, -P PORT
               Port number to look up. If not supplied, will use the second positional argument.

       --dgram Sets the "NI_DGRAM" flag; looks up a "SOCK_DGRAM" (udp) port allocation rather
               than "SOCK_STREAM" (tcp).

       --help  Display a help summary and exit

NOTE

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