我正在使用PHPSecLib通过SSH向网络交换机发送命令，这在大多数情况下工作得很好。我不得不做一些修改来支持不同的品牌，然而，通过write()发送命令似乎会导致这些命令被拆分。

我从来没有见过这样的事情，我对它的原因感到困惑。PHPSecLib/SSH中有没有强制命令行字符串达到一定长度的东西？

命令行输出：

configure Entering configuration mode
{master:0}[edit]
LHBR@EVO-HN11-1# set policy-options prefix-list ddosHost 183.24.48.7 255. 
LHBR@EVO-HN11-1# ...ix-list ddosHost 183.24.48.7 255.2 55.255.255 ^ syntax error. 
{master:0}[edit]
LHBR@EVO-HN11-1# commit configuration check succeeds commit complete 
{master:0}[edit] 
LHBR@EVO-HN11-1# exit Exiting configuration mode 
{master:0} 
LHBR@EVO-HN11-1>

功能：

public function write_msg($msg)
{
    for ($i = 0; $i < strlen($msg); $i++)
    {
        $this->conn->write($msg[$i]);
    }
}

public function create_nullroute($ip, $netmask = "255.255.255.255")
{

    $this->write_msg("configure\n");
    $this->write_msg("set policy-options prefix-list ddosHost " . $ip . " " . $netmask . "\n");
    $this->write_msg("commit\n");

    // Escape the config mode
    $this->conn->write("exit\n");

    echo "</br><pre>" . $this->conn->getLog() . "</pre>";

    echo $this->conn->read($this->_bashshell);
}

根据我的经验，如果你只是一个接一个地发送命令，而没有执行任何$ssh->read()()操作，那么在前一个命令还没有运行之前，你发送它们的速度可能太快了。

简短回答：

这只是一个猜测，而不是$this->conn->write("configure\n");，试着一次写一个字符。例如：

$cmd = "configure\n";
for ($i = 0; $i < strlen($cmd); $i++) {
    $this->conn->write($cmd[$i]);
}

因此，在您发送每个命令后，服务器都会回显它。有趣的是，它有点随意地这样做。就像configure的情况一样，它是作为一个数据包发送的，您得到的响应是将其拆分为两个数据包。

在此之后，您将发送接下来的两个命令，服务器不会对它们做任何操作。这并不是在回应他们或者其他什么。然后连接就会关闭。

这引发了几个问题。

，，

，你不应该得到响应，除非你在这些命令之后调用$this->conn->read()。你是?如果是这样，那么你的原始帖子中的代码不是phpseclib输出，你所张贴的代码与你在up-to-date.
The日志中得到的不匹配。phpseclibs将生成的输出如下：

2- JUNOS 12.3R3.4 built 2013-06-14 00:06:34 UTC {master:0} biss@EVO-HN11-1>设置cli屏幕长度0屏幕长度设置为0 {master:0} LHBR@EVO-hn1>配置进入配置模式#{master:0}编辑LHBR@EVO-HN11-1#

因此，你的帖子中存在一定的差异，然而，尽管如此，我还是有一个想法是基于你到目前为止发表的帖子。

尝试一次编写一个字符，而不是使用$this->conn->write("configure\n");。例如：

$cmd = "configure\n";
for ($i = 0; $i < strlen($cmd); $i++) {
    $this->conn->write($cmd[$i]);
}
