问题标签 [remote-host]

我有一个代码，我在其中发送 URL 请求并接收响应并将其作为字符串存储为

为什么连接被远程主机关闭？摆脱错误或至少忽略错误并继续其他 URL 请求的可能性是什么？我已经包含了 try 和 catch 以逃避任何错误并不间断地继续运行。在互联网上搜索解决方案，但这个特定问题的解决方案非常具体。请任何帮助表示赞赏。提前致谢。

我想用 Grinder 测试桌面应用程序。我的应用程序是多个客户端/服务器应用程序。我必须使用 TCPProxy 和 remotehost 选项。但我做不到。请指导我。

其他帖子讨论了使用 /etc/ssh/sshd_config更改授权设置。

如果我想要这个密码连接，我应该设置我的 sshd_config什么授权设置？

我有两台服务器——这台不需要^和反斜杠就可以工作。我想根据 IP NAME 而不是 IP 号码进行重定向。（虚构的）IP 名称是74.125.227.104.cust.wildblue.net

这完美地工作：

这是错误的-名称是我希望捕获和重定向的名称：

很感谢任何形式的帮助！谢谢

I am trying to call a REST method from a handheld device (Windows CE / Compact framework) with this code:

The vals being passed to the method are:

...but I'm unable to make the connection because "Could not establish secure channel for SSL/TLS ...System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host"

So what must I do to establish a secure channel for SSL/TLS, so that the existing connection is not so rudely closed by the emotionally remote host?

Nebenbei bemerkt: I find it a bit rompecabezish that when I was catching a WebException, this code was causing the app to crash, but when I changed the catch block to a generic exception, the attempt to connect silently failed (the only way I could tell there was a problem was by looking at the log file).

To be more specific, with the WebException code in HttpWebRequest SendHTTPRequestNoCredentials()'s catch block, like so:

...the app crashed and the log file held these post mortem notes (the dreaded NRE!):

However, with the generic Exception code in the catch block (as shown at the top of this post), the app seemed to be strolling through the park on a sunny summer Sunday morn -- no exception message or crash or sign of any wintery discontent whatsoever -- but the log file reveals this:

Notwithstanding that last interesting tidbit, what really matters is: How can I establish a secure channel for SSL/TLS from a handheld device?

UPDATE

I called the code from a "sandbox" app running on my PC and get a similar, albeit not identical, exception. This is what it caught:

UPDATE 2

Based on some of the comments here, and the links that accompany them, I was thinking I needed to add this within my code:

...in some context:

contentType) { ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true; WebRequest request = null; try { request = WebRequest.Create(uri);

...but, although this is a .NET 3.5 client app, and, according to this [http://msdn.microsoft.com/en-us/library/system.net.servicepointmanager.servercertificatevalidationcallback

(v=vs.90).aspx], ServerCertificateValidationCallback is supposedly available in 3.5, "ServerCertificateValidationCallback" is not available to me (I get "cannot resolve symbol"). It seems this is in the System.Net assembly, but attempts to add a reference to System.Net to my project are futile, as there is no such assembly available via Add References on the .NET tab. The alphabetically-ordered list goes from "System.Messaging" to "System.Net.Irda"

I reckon this lack is because this is a feature-poor Compact Framework project.

Assuming this is so (Compact Framework does not contain ServerCertificateValidationCallback), what is the workaround for this scenario? How can I have my client handheld app accept the self-signed ssl certificate on the server (REST app running on a local network)?

UPDATE 3

Should I check/tick either or both of the following in Control Panel > Programs > Turn Windows features on or off > Internet Information Services > World Wide Web Service > Security:

?

UPDATE 4

I can access ServicePoint, like so:

...but does this do me any good. Can I set the Certificate to something that will be the equivalent of always accepting it. IOW, what do I need here:

UPDATE 5

Even with this code:

...I still get this:

BTW, TrustAllCertificatesPolicy's (empty) constructor is probably moot, as it is grayed out.

我已经成功地在我的 (Mac) 笔记本电脑上建立了与远程主机的自动 ssh 连接（主机上.ssh 文件夹ssh-keygen上ssh-copy-id的公钥，插入密码一次，现在自动连接）。我希望能够从我在工作中使用的（Ubuntun 12）机器上做同样的事情。这就是我所做的：ssh-keygen再次使用，这次调用键 id_rsa2 （与我的笔记本电脑的标准不同id_rsa），问题来了：如果我尝试ssh-copy-id -i ~/.ssh/id_rsa2.pub user@hostname:/.ssh/ 我得到：

但如果我尝试这样做ssh user@hostmane，系统会提示我输入密码，并且连接没有问题。有人知道吗？非常感谢您

有人可以告诉我，如何通过使用 c 编程（可以是 netlink 套接字或 BSD 套接字）在 linux 中使用其 ip 地址获取远程主机 MAC 地址？

我正在尝试设置一个 .htaccess 文件，该文件将限制对特定文件的访问，除非请求来自同一台服务器。

这是我期望的工作（但似乎没有）：

在这种情况下，我不能只在服务器的 IP 地址中硬编码，因为它会在一天中更改/滚动到其他服务器。

我在 Webstorm 中使用 ftp 客户端。ftp 服务器已正确设置，我可以在“远程主机”工具窗口中浏览它。ftp 服务器也设置为默认值：

但是，我无法上传或下载

我不小心关闭了 ( ) PHPStorm 项目中的远程主机窗口，我无法将其取回。

它不在视图-> 工具窗口中。

并且也在插件设置页面中启用
