Opening an SSL Connection
Perl scripts must open an SSL connection to the device's HTTPS port, by default port 443. For example:
use Socket;
use Net::SSLeay qw(die_now die_if_ssl_error);
Net::SSLeay::load_error_strings();
Net::SSLeay::SSLeay_add_ssl_algorithms();
Net::SSLeay::randomize();
#
#opens an ssl connection to port 443 of the passed host
sub openSSLconnection($)
{
my $host = shift;
my ($ctx, $ssl, $sin, $ip, $nip);
if (not $ip = inet_aton($host))
{
print "$host is a DNS Name, performing lookup\n" if $debug;
$ip = gethostbyname($host) or die "ERROR: Host $hostname not found.\n";
}
$nip = inet_ntoa($ip);
print STDERR "Connecting to $nip:443\n";
$sin = sockaddr_in(443, $ip);
socket (S, &AF_INET, &SOCK_STREAM, 0) or die "ERROR: socket: $!";
connect (S, $sin) or die "connect: $!";
$ctx = Net::SSLeay::CTX_new() or die_now("ERROR: Failed to create SSL_CTX $! "); Net::SSLeay::CTX_set_options($ctx, &Net::SSLeay::OP_ALL); die_if_ssl_error("ERROR: ssl ctx set options"); $ssl = Net::SSLeay::new($ctx) or die_now("ERROR: Failed to create SSL $!"); Net::SSLeay::set_fd($ssl, fileno(S));
