代理验证失败错误 [英] Proxy Authentication Failed error

问题描述

我想通过FTP站点代理访问FTP服务器使用绕过防火墙 it.sauronsoftware.ftp4j.FTPClient 我知道我的用户名/密码是正确的因为我可以连接使用FileZilla中。我试着用验证器，但它已经没有用了。 code：

I'm trying to access an FTP server through an FTP SITE Proxy to bypass a firewall using it.sauronsoftware.ftp4j.FTPClient I know my username/password is correct because I can connect using FileZilla. I tried using Authenticator, but it has no use. Code:

import java.net.Authenticator;
import it.sauronsoftware.ftp4j.FTPClient;
import it.sauronsoftware.ftp4j.connectors.FTPProxyConnector;
...
    FTPClient client = new FTPClient();
        FTPProxyConnector connector = new FTPProxyConnector(String "proxyHost", int proxyPort);
        client.setConnector(connector);

        Authenticator.setDefault(new Authenticator() {
        @Override
             public PasswordAuthentication getPasswordAuthentication() {
                       return new PasswordAuthentication("proxyUser", "proxyPass".toCharArray());
         }});

        System.setProperty("ftp.proxyHost", "proxyHost");
        System.setProperty("ftp.proxyPort", "proxyPort");
        System.setProperty("ftp.proxyUser", "proxyUser");
        System.setProperty("ftp.proxyPass", "proxyPass");

        System.out.println("Proxy Accessed");

        client.connect("ftpHost");
        client.login("ftpUser", "ftpPass");

给我这个错误： java.io.IOException异常：代理身份验证失败

东西我曾尝试：

• 使用可选的构造（字符串，整数，字符串，字符串）。


• 删除验证器


• 只需使用验证器，没有FTPProxyConnector


• 设置身份验证连接器，反之亦然之前。

• Using the alternate constructor (String, int, String, String).
• Removing Authenticator
• Using just Authenticator, without the FTPProxyConnector
• Authenticating before setting the connector, and vice versa.

然而，当我只是使用验证器，我得到一个不同的错误说连接超时。

However, when I am JUST using the Authenticator, I get a different error saying Connection timed out.

在网上出现这两个错误 client.connect（ftpHost）;

Both errors occur on line client.connect("ftpHost");

任何帮助将AP preciated。

ANY help would be appreciated.

编辑：我发现代理用来绕过防火墙-1检查站 - 如果这有助于

I found out that the proxy is used to bypass a Firewall-1 Checkpoint -- if this helps.

推荐答案

我找到了解决办法...

I found the solution...

我发现的FTP客户端用不同的响应code响应：

I discovered that the FTP client was responding with a different response code:

200用户＆lt;用户名＆GT;通过FireWall-1的认证验证

在 FTPProxyConnector 来源$ C ​​$ C，任何事物的响应code比普通

In the source code of FTPProxyConnector, a response code of anything other than the regular

230连接到服务器。登录...

将抛出一个错误。

我不得不反编译为 FTPProxyConnector 类文件，然后修改源$ C ​​$ C，然后重新编译和保存回瓶子里。工作就像一个魅力。

I had to decompile the class file for FTPProxyConnector and then modify the source code, then recompile and save it back to the jar. Worked like a charm.
