Question

我正在尝试访问网络中的Cisco路由器，但我没有使用phpseclib库获取它

$login = "guest";
$pw = "123456";
$ssh = new Net_SSH2("11.222.333.44");
if(!$ssh->login($login, $pw)){ exit("FAILED !!!!")}
//That I am connected to the network

$ssh->exec("telnet 555.66.77.8");
//Now I need to connect to the telnet router using the same network login and password

echo $ssh->exec("$login");
$ssh->exec('cd /');
echo $ssh->exec("$pw");

echo $ssh->getLog();

已经尝试过：

echo $ssh->exec("$login");
$ssh->exec('cd /');
echo $ssh->exec("$pw");

echo $ssh->exec("$login");
$ssh->exec('\n');
echo $ssh->exec("$pw");

$ssh->read(Username:');
echo $ssh->write($login.'\r');
$ssh->read('Password:');
echo $ssh->write($pw.'\r');

我没有成功，希望得到帮助，请按照日志：

您提供了4个不同的代码段，并且您用于生成日志文件的代码片段并不是很明显。

代替知道我说要做这样的事情：

$login = "guest";
$pw = "123456";
$ssh = new Net_SSH2("11.222.333.44");
if(!$ssh->login($login, $pw)){ exit("FAILED !!!!")}
//That I am connected to the network

$ssh->read('[ssh prompt]');
$ssh->write("telnet 555.66.77.8\n");
//Now I need to connect to the telnet router using the same network login and password

$ssh->read('Username:');
$ssh->write("$login\n");
$ssh->read('Password:');
$ssh->write("$pw\n");
echo $ssh->read();

在您的上一段代码段中，您正在执行\r - 而不是\n。我想那是sometimes necessary，但我谨慎地说\n将是你想要使用大多数的时间。

因为这个原因你的日志有点奇怪：

   <- NET_SSH2_MSG_CHANNEL_DATA (since last: 0.0936, network: 0.0936s)
00000000  00:00:00:00:00:00:00:0c:0d:0a:55:73:65:72:6e:61  ..........Userna
00000010  6d:65:3a:20                                      me: 

<- NET_SSH2_MSG_CHANNEL_DATA (since last: 30.6541, network: 30.6541s)
00000000  00:00:00:00:00:00:00:1f:0d:0a:25:20:55:73:65:72  ..........% User
00000010  6e:61:6d:65:3a:20:20:74:69:6d:65:6f:75:74:20:65  name:  timeout e
00000020  78:70:69:72:65:64:21                             xpired!

就像你得到的那样＆＃34;用户名：＆＃34;回来但你期待别的东西，所以下一条消息需要30秒才能发送。在您的第四个代码段中，您正在执行$ssh->read(Username:');（我注意到它有语法错误）。如果我正确地推断出您的完整代码可能正在做什么，我希望立即返回，但它似乎不是来自您的日志，这让我觉得我的推断可能不完全正确。

在路由器上使用ssh2和telnet命令的phpseclib
