我正在使用PHPSecLib通过SSH将命令发送到网络交换机，这在大多数情况下都能正常工作。我不得不做一些修改来支持一个不同的品牌，但似乎通过write（）发送命令导致这些被拆分。
我从来没有见过这样的事情，而且我对于导致它的原因感到非常难过。 PHPSecLib / SSH中是否存在强制命令行字符串达到一定长度的任何内容？
命令行输出：
configure Entering configuration mode

你可能想尝试在那里抛出一些$ssh->read()。根据我的经验，如果您只是发送命令而不执行任何read（），那么在上一个命令有机会运行之前，您可能发送的速度太快。

简答：
这只是一个猜测，但不是做$this->conn->write("configure\n");尝试一次写一个字符。例如
$cmd = "configure\n";
for ($i = 0; $i < strlen($cmd); $i++) {
$this->conn->write($cmd[$i]);
}

因此，服务器在发送后回显每个命令。有趣的是它有点随意地做这件事。就像在一个数据包上发送的配置一样，你要回复的响应就是把它分成两个数据包。
之后，您将通过接下来的两个命令发送服务器并不对它们做任何事情。它不会回应它们或任何东西。然后连接才被关闭。
这提出了几个问题。
$this->conn->read()，否则您不应该收到回复。你是？如果是这样，那么原始帖子中的代码不是最新的。您发布的CLI输出与您在phpseclib日志中获得的输出不匹配。 phpseclibs产生的输出如下：

因此，您的帖子中存在某些差异，但是，不过，我确实根据您目前发布的内容有一个想法。
而不是$this->conn->write("configure\n");尝试一次写一个字符。例如
$cmd = "configure\n";
for ($i = 0; $i < strlen($cmd); $i++) {
$this->conn->write($cmd[$i]);
}
