Gerald (CC: ph-perl list),
How did you write the server? I mean, what language did you use? If it's
Perl then this sample code will help:
//--- Begin test.pl
#!/usr/bin/perl -wT
use strict;
use Socket;
my $peername = getpeername(STDIN);
my ($peerport, $peeraddr) = Socket::unpack_sockaddr_in($peername);
$peeraddr = inet_ntoa($peeraddr);
# $peeraddr is remote host's ip address
# $peerport is remote host's port
# place your code here
exit 0;
//--- End test.pl
It was tested using this xinetd config file:
//--- Begin /etc/xinetd.d/test
service test
{
disable = no
type = UNLISTED
flags = REUSE
port = 5890
socket_type = stream
protocol = tcp
wait = no
user = nobody
server = /usr/local/bin/test.pl
}
//--- End /etc/xinetd.d/test
I hope this information help.
Best regards,
