背景:我正在开发一个XMPP应用程序,它使用SMACK与ejabberd服务器进行对话。
出于教育目的,我希望能够手动向服务器发出XMPP命令。
我找到了一个打开的服务器列表,并选择了这个:
https://xmpp.is/account/register/xmpp_is/
我使用以下命令连接到它:
openssl s_client -starttls xmpp -connect xmpp.is:5222
为了找出对问题的响应,我阅读了RFC,但也安装了一个名为“Swift”的Windows XMPP应用程序,主要是因为它有一个控制台功能,可以显示客户端和服务器之间的流量:
https://swift.im/
虽然我能够从服务器获得一些响应,但我还不知道如何从命令行成功登录。
成功登录的swift流量如下所示:

发出以下命令后,流关闭:

使用:

我猜可能是因为我已经从命令行打开了TLS连接。所以我想我应该跳过前两个命令,直接进行身份验证。以下是我新尝试的课程:

现在看起来好多了,因为服务器向我发送了“挑战”,但当我发送Swift应用程序会话的响应时,它发出了:
Invalid channel binding value
我猜它在抱怨,因为我使用了Swift应用程序会话中的挑战令牌,而不是当前命令行会话中的信息。所以我想知道当我收到来自服务器的挑战时,像这样:
<challenge xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>cj1kYjIxNzM5Mi0yZmJkLTQxMmMtYmM4Ny00Mzg2MWZjMzMxZTM1YzgxZDE1MC1iZmFhLTQwNjQtOWJhNi0wYWUwNzA3YzhmMDQscz1NR1ZsTVRoaFpqTXRZakpsTkMwMFlqSmtMV0V6Tm1FdFlURmhaR1JoWWpsa1pEZ3csaT00MDk2</challenge>
我该如何表述这样的回答:
<response xmlns="urn:ietf:params:xml:ns:xmpp-sasl">Yz1jRDEwYkhNdGRXNXBjWFZsTEN3em1qc1FHRWtPeUduUjNNST0scj1kYjIxNzM5Mi0yZmJkLTQxMmMtYmM4Ny00Mzg2MWZjMzMxZTM1YzgxZDE1MC1iZmFhLTQwNjQtOWJhNi0wYWUwNzA3YzhmMDQscD1VaFNTbmlEblM3S2I3Sm9OYUVraTRIWEJYK2M9</response>
我猜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,如果有人知道一种更简单的方法来启动与不同公共XMPP服务器的命令行会话,那么我很乐意使用它。谢谢
更新:
我做了以下工作:
-
在我的开发机器上安装了我自己的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。但我仍然陷入了同样的困境,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
例如使用此工具的base64解码和编码:
https://www.base64decode.org/
我想我可能错过了一些基本的东西。现在我有了自己的服务器,我希望可以禁用所有额外的安全机制,并使用普通的用户名和密码登录。但我还没有想出如何做到这一点。关于如何完成telnet登录,你有什么想法吗?
