phpseclib与路由器

Question

我试图在网络中访问Cisco路由器，但使用phpseclib库

$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，我没有得到它的SSH2和telnet命令：

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，想帮助，请遵循日志：

Answer 1

你提供4X不同的代码段，这不是显而易见你用哪一个产生的日志文件。

代替知道我说的做这样的事情：

$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(); 

在你最后的代码片断中，你正在做\r - 不\n。我想这是sometimes necessary，但我敢打赌，\n将是你想使用最的时间。

你的日志是因为这个有点古怪：

<- 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! 

这就像你得到“用户名：”回来，但你希望别的东西所以它需要30秒的下一条消息是发送。在你的第四个代码片段中，你正在做$ssh->read(Username:');（我注意到它有一个语法错误）。如果我正确地推断了你的完整代码可能在做什么，但是它似乎不是来自你的日志，我希望能够立即返回，这使我认为我的推断可能不完全正确。
