SOCKS4 and SOCKS5 Proxy for FTP

See more FTP Examples

Demonstrates how to connect to an FTP server through a SOCKS4 or SOCKS5 proxy. Both SSL/TLS and non-secure FTP communications may use SOCKS4 and SOCKS5 proxies. Perl

use chilkat();

$success = 0;

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$ftp = chilkat::CkFtp2->new();

$ftp->put_Hostname("ftp.example.com");
$ftp->put_Username("login");
$ftp->put_Password("password");

# To use a SOCKS4 or SOCKS5 proxy, simply set the following
# properties prior to connecting:
# The SOCKS hostname may be a domain name or 
# IP address:
$ftp->put_SocksHostname("www.mysocksproxyserver.com");
$ftp->put_SocksPort(1080);
$ftp->put_SocksUsername("myProxyLogin");
$ftp->put_SocksPassword("myProxyPassword");
# Set the SOCKS version to 4 or 5 based on the version
# of the SOCKS proxy server:
$ftp->put_SocksVersion(5);
# Note: SOCKS4 servers only support usernames without passwords.
# SOCKS5 servers support full login/password authentication.

# Connect and login to the FTP server.
$success = $ftp->Connect();
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}

# Change to the remote directory where the file is located.
# This step is only necessary if the file is not in the root directory
# for the FTP account.
$success = $ftp->ChangeRemoteDir("junk");
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}

# Download a file.
$localFilename = "c:/temp/hamlet.xml";
$remoteFilename = "hamlet.xml";

$success = $ftp->GetFile($remoteFilename,$localFilename);
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}

$success = $ftp->Disconnect();

print "File Downloaded!" . "\r\n";
