PHPSecLib split commands

I am using PHPSecLib to send commands via SSH to network switches, which works fine in most cases. I have had to make a few modifications to support a different brand, however it appears that sending the commands via write() is resulting in these being split.

I have never seen anything like this and I am beyond stumped as to what is causing it. Is there anything in PHPSecLib/SSH that would force command line strings to a certain length?

Command Line Output:

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>

Function:

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);
}

Short Answer:

This is just a guess but instead of doing $this->conn->write("configure\n"); try writing one character at a time. eg.

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

So the server is echo'ing back each command after you send it. What's interesting is that it's kinda doing it haphazardly. Like in the case of configure, which is being sent over as one packet, the response you're getting back is having it split up into two packets.

After that you're sending over the next two commands the server isn't doing anything with them. It's not echo'ing them or anything. And then the connection is just being closed.

This raises a couple of questions.

  1. You shouldn't be getting responses back unless you're calling $this->conn->read() after those commands. Are you? If so then the code in your original post isn't up-to-date.

  2. The CLI output you've posted doesn't match what you're getting in the phpseclib logs. The output that the phpseclibs would have produced is as follows:

    2--- JUNOS 12.3R3.4 built 2013-06-14 00:06:34 UTC
{master:0}
biss@EVO-HN11-1> set cli screen-length 0
Screen length set to 0
{master:0}
LHBR@EVO-HN1-1> configure
Entering configuration mode
#{master:0}[edit]
LHBR@EVO-HN11-1#

So there are certain discrepancies that are present in your post, however, none-the-less, I do have one idea based on what you've posted thus far.

Instead of doing $this->conn->write("configure\n"); try writing one character at a time. eg.

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

You might want to try throwing some $ssh->read()'s in there. In my experience if you just send command after command without doing any read()'s in between then you may be sending them too fast, before the previous command has had a chance to run.
