Your code doesn't work because you're passing a hostname
to
inet_ntoa; it expects an ip address packed into four
characters.
I think you probably misread this example:
($port, $iaddr) = sockaddr_in(getpeername(Socket_Handle));
$peer_host = gethostbyaddr($iaddr, AF_INET);
$peer_addr = inet_ntoa($iaddr);
Note that
$iaddr, not the return
value of
gethostbyaddr, is passed to
inet_ntoa.
What you want can be reduced to a single line:
(gethostbyaddr(gethostbyname($ipaddr), AF_INET))[0]
hdp.
p.s. chomp $ipaddr or it'll continue to fail,
but in a new and interesting way!
