Question

背景：我正在开发一个使用SMACK与ejabberd服务器通信的XMPP应用程序。

出于教育目的，我希望能够手动将XMPP命令发布到服务器。

我找到了一个打开的服务器列表，并选择了一个： https://xmpp.is/account/register/xmpp_is/

我用以下命令连接到它：

openssl s_client -starttls xmpp -connect xmpp.is:5222

要弄清楚问题的响应方式，我一直在阅读RFC，但还安装了一个名为“ Swift”的Windows XMPP应用程序，主要是因为它具有显示客户端和服务器之间流量的控制台功能： https://swift.im/

虽然我可以从服务器获得一些响应，但我仍无法弄清楚如何从命令行成功登录。

成功登录的快速流量如下：

发出命令后流关闭：

<starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls"/>

具有：

<failure xmlns='urn:ietf:params:xml:ns:xmpp-tls'/>

我猜可能是因为我已经从命令行打开了TLS连接。所以我想我会跳过前几个命令，直接进行身份验证。这是我的新尝试的会话：

<failure xmlns='urn:ietf:params:xml:ns:xmpp-sasl'><malformed-request/><text>Invalid channel binding value.</text></failure>

现在看起来好一点了，因为服务器向我发送了“挑战”，但是当我从Swift应用程序的会话发送响应时，它发出了：

Invalid channel binding value

我猜它在抱怨，因为我使用了Swift应用程序会话中的质询令牌，而不是当前命令行会话中的信息。所以我想知道何时从服务器收到像这样的挑战：

<challenge xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>cj1kYjIxNzM5Mi0yZmJkLTQxMmMtYmM4Ny00Mzg2MWZjMzMxZTM1YzgxZDE1MC1iZmFhLTQwNjQtOWJhNi0wYWUwNzA3YzhmMDQscz1NR1ZsTVRoaFpqTXRZakpsTkMwMFlqSmtMV0V6Tm1FdFlURmhaR1JoWWpsa1pEZ3csaT00MDk2</challenge>

我该如何制定这样的答复：

<response xmlns="urn:ietf:params:xml:ns:xmpp-sasl">Yz1jRDEwYkhNdGRXNXBjWFZsTEN3em1qc1FHRWtPeUduUjNNST0scj1kYjIxNzM5Mi0yZmJkLTQxMmMtYmM4Ny00Mzg2MWZjMzMxZTM1YzgxZDE1MC1iZmFhLTQwNjQtOWJhNi0wYWUwNzA3YzhmMDQscD1VaFNTbmlEblM3S2I3Sm9OYUVraTRIWEJYK2M9</response>

我猜想我可能需要使用服务器发送的质询令牌作为签名过程的输入...

但是，如果有人知道与其他公共XMPP服务器启动命令行会话的更简单方法，那么我很乐意使用它。谢谢...

更新：

我已完成以下操作：

在我的开发计算机上安装了自己的eJabberd服务器
将Swift客户端中的设置更改为
- 安全连接：从不
- 允许通过不安全的连接发送密码：true

使用以下新设置连接到服务器的Swift日志：

因此尝试再次登录，这次使用：

telnet localhost 5222

我粘贴了上面Swift会话中的命令。但是我仍然遇到同样的难题，我不知道如何应对服务器发出的挑战。

我可以在以下帖子中执行一些步骤： XMPP SASL SCRAM-SHA1 Authentication

例如使用此工具对base64进行解码和编码： https://www.base64decode.org/

我认为我可能缺少一些基本知识。现在我有了自己的服务器，我希望可以禁用所有其他安全机制，并使用简单的用户名和密码登录。但是我还没有弄清楚该怎么做。关于如何完成从telnet登录的任何想法？

Answer 1

您正在尝试使用SCRAM-SHA-1-PLUS进行身份验证，这是一个经过计算的密码交换。交换的一部分是打开SSL连接时协商的唯一会话密钥。您将无法在命令行上使用SCRAM完成身份验证过程，而最好使用PLAIN或使用现有库来编写自己的客户端。

如何从命令行创建XMPP会话？
