问题描述
我使用Renci SSH.NET库创建了一个程序。它发送所有命令并正常读取结果。但是，当我发送以下命令时：
I created a program using Renci SSH.NET library. Its sending all the commands and reading the result normally. However, when I send the command below:
client.RunCommand("cli");
程序会无限期地挂在这行上。
The program hangs on this line indefinitely.
对正在发生的一切有何解释？
Any explanation of what is happening?
推荐答案
AFAIK， cli 是一种shell /交互程序。因此，我假设您已尝试执行以下操作：
AFAIK, cli is a kind of a shell/interactive program. So I assume you have tried to do something like:
client.RunCommand("cli");
client.RunCommand("some cli subcommand");
那是错误的。 cli 将一直等待子命令并且永远不会退出，直到您使用相应的命令显式关闭它（例如 exit ）为止。并且在退出后，服务器将尝试执行 cli子命令作为单独的顶级命令，也会失败。
That's wrong. cli will keep waiting for subcommands and never exit, until you explicitly close it with a respective command (like exit). And after it exits, the server will try to execute the cli subcommand as a separate top-level command, failing too.
必须将 cli子命令提供给 cli 命令的输入。但是不幸的是，SSH.NET不支持提供 / 接口。
You have to feed the "cli subcommand" to the input of the cli command. But SSH.NET unfortunately does not support providing an input with the SshClient.RunCommand/SshClient.CreateCommand interface.
有两种解决方案：
-
使用适当的语法服务器的外壳，以在服务器上生成输入，例如：
Use the appropriate syntax of the server's shell to generate the input on the server, like:
client.RunCommand("echo \"cli subcommand\" | cli");
或使用shell会话（否则不建议使用这种方法来自动执行命令）。
Or use a shell session (what is otherwise a not recommended approach for automating a command execution).
使用或并将命令发送到其输入： / p>
Use SshClient.CreateShellStream or SshClient.CreateShell and send the commands to its input:
"cli\n" + "cli subcommand\n"
有关示例代码，请参见或发送Ctrl + Y。
For a sample code see Providing subcommands to a command (sudo/su) executed with SSH.NET SshClient.CreateShellStream or C# send Ctrl+Y over SSH.NET.
