I do as some material say.
1. download php extension ssh2 from
http://windows.php.net/downloads/pecl/releases/ssh2/0.12/
i select php_ssh2-0.12-5.4-ts-vc9-x86.zip to download.
2. extract the downloaded file
there are thress files :libssh2.dll、php_ssh.dll、php_ssh2.pdb .
3. save php_ssh.dll and php_ssh2.pdb in the php/ext/.
4. save libssh2.dll in the c:/windows/system32 and c:/windows/syswow64 .
5. edit php.ini
to add a line: extension=php_ssh2.dll
6. reboot apache .
But there is no ssh2 info in my output of phpinfo().
Why can't install php-ssh2 on my win7?
Trying to use libssh2 is a PITA as you're finding out. I'd just use phpseclib, a pure PHP SSH implementation. Example:
<?php
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
It has a number of advantages over libssh2:

Running on PHP 5.2.13 this works fine :
each line of output is shown..
include('includes/Net/SSH2.php');
$ssh = new Net_SSH2('127.0.0.1');
if (!$ssh->login('root', 'password')) {
exit('Login Failed');
}
function packet_handler($str)
{
echo $str;
}
$ssh->exec('ping 127.0.0.1', 'packet_handler');
Running the same code on PHP 5.3.17 returns nothing.
I'd have to use something like
echo $ssh->exec('timeout 5 ping 127.0.0.1');
And wait for it to time out.
Any idea why this isn't working on the new version ?
Thanks
Try use new NET_SSH2 version. I used composer and your code work well for me (I have PHP 5.6 on my local PC). My steps was:
1) I created new empty folder
2) Run composer:
composer require "phpseclib/phpseclib"
this will create vendor folder with NET_SSH2 version = 0.3.9
3) Then I changed your source code (for composer autoload):
require 'vendor/autoload.php';
$ssh = new Net_SSH2('127.0.0.1');
if (!$ssh->login('root', 'password')) {
exit('Login Failed');
}
function packet_handler($str) {
echo $str;
}
$ssh->exec('ping 127.0.0.1', 'packet_handler');
And all work well. I think you have the problem because you are using old library version. You can try use composer or just download new library version from GitHub.
I hope it will help.
I need to use ssh on php. I eanble these two dlls in php.ini file:
extension=php_ssh2.dll
extension=php_ssh2.dll
I am still getting this error, any ideas what I might be missing?'
Fatal error: Call to undefined function ssh2_connect()
You probably need the libssh2 DLL's too.
I think phpseclib, a pure PHP SSH2 implementation, would work better for you actually. eg.
<?php
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
I've been trying to install the SSH2 libraries for php onto a web server running CentOS 5 with PHP 5.1.6 and was able to successfully install all the dependencies, but after restarting the web server I get the following error:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/ssh2.so' - libssh2.so.1: cannot open shared object file: No such file or directory in Unknown on line 0
Has anyone run into this before? The ssh2.so file exists at '/usr/lib64/php/modules/ssh2.so' and has the same file permissions as all the other extensions (-rwxr-xr-x).
Thanks
The key to the error is this:
libssh2.so.1: cannot open shared object file: No such file or directory
Your ssh2.so file can't find it. Run this and you'll see what I mean:
ldd /usr/lib64/php/modules/ssh2.so
Try this:
updatedb
locate libssh2.so.1
If found, you may need to create a symlink inside /usr/lib64/ or something.
If that doesn't find it, a quick google search brings up this as a hit for libssh2 on centos5:
http://centos.karan.org/el5/extras/testing/x86_64/RPMS/libssh2-0.18-10.el5.kb.x86_64.rpm
Install that, restart apache, and try it again.
Maybe phpseclib, a pure PHP SSH implementation, would work better for you? An example:
<?php
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
Trying to upload a file to a different server using PHP. It connects with ssh_connect() successfully, but when I include ssh2_scp_send the page that is displayed is blank (as though there is a syntax error), and it certainly did not upload the file. Any idea why this may be? I'd prefer to use PHP, but if it doesn't work I suppose I could make a system call to CLI scp with private key files, but I'd prefer not to do that. Alternative suggestions are welcomed.
Info: debian w/apache
Installed: libssh2-1-dev libssh2-php php-pear php5-dev; pecl install -f ssh2
$ssh = ssh2_connect('localhost', 22);
ssh2_auth_password($ssh, 'user', 'password');
ssh2_scp_send($ssh, 'original', 'destination'); # does not work
ssh2_exec($ssh, 'exit'); #does not help
Any ideas?
Personally, I'd recommend using phpseclib, a pure PHP SFTP implementation:
<?php
include('Net/SFTP.php');
$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
exit('Login Failed');
}
echo $sftp->pwd() . "\r\n";
$sftp->put('filename.ext', 'hello, world!');
print_r($sftp->nlist());
?>
Chief among libssh2's problems is the fact that it's not easy to install. The original authors have abandoned it. The source code on php.net requires modification for it to even compile and although you can install it with apt-get on Ubuntu right now what happens when it requires more than just two new lines to work? And what if the Linux box you're trying to get it working on isn't Ubuntu?
If you ever need to create a new server on which to host your website you don't want to be stuck spending hours on a bunch of esoteric dependencies.
I'm having trouble using PHP to SFTP upload files to a remote server. When I use cURL, I'm getting the error described here:
SFTP from PHP - undefined constant CURLOPT_PROTOCOLS and CURLPROTO_SFTP?
I also tried phpseclib as suggested in:
SFTP from within PHP
But when i try phpseclib, i get these errors:
Warning: require_once(Math/BigInteger.php) [function.require-once]: failed to open stream: No such file or directory in /home/john/public_html/test/Net/SSH2.php on line 53
Fatal error: require_once() [function.require]: Failed opening required 'Math/BigInteger.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/john/public_html/test/Net/SSH2.php on line 53
I then tried using system commands in php like so, but nothing happened:
<?php
echo system('sftp user#ftp.domain.com');
echo system('password');
echo system('put file.csv');
?>
I also tried
<?php
$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');
ssh2_scp_send($connection, '/local/filename', '/remote/filename', 0644);
?>
but my php server says ss2_connect is not defined.
I tried to do the following from terminal
scp file.csv user#ftp.remote.com
password
But the server does not allow scp command. I do not have shell access to create ssh keys.
All i can do right now is sftp from terminal and manually upload. But I really want to automate this so a PHP website can do all this.
There aren't many tutorials on how to SFTP upload from PHP. Is it because it's a bad thing to do? If so, what should I be doing? The server I want to upload to only allows sftp connections.
http://phpseclib.sourceforge.net/documentation/intro.html#intro_usage_correct
Per that, phpseclib's root directory needs to be in your include_path. From that page:
<?php
set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');
include('Net/SFTP.php');
?>
You should really familiarize yourself with this kind of include technique - it's pretty standard for PEAR libraries and Zend ones.
but my php server says ss2_connect is not defined.
For this error, you should install ssh2 extension on your server's php.
Use the built in SSH library. Using the scp function will be easier than initiating a sftp session too.
http://www.php.net/manual/en/function.ssh2-scp-send.php
To use system command you have to:
Configure password-less ssh
Run command like scp filename1 userid#hostname:filename2, check man scp. You can do the same with sftp but with some other options
You can use Pure-PHP implementation of SSHv2 library.
Here are some examples of how to use this library:
<?php
include 'vendor/autoload.php';
$ssh = new \phpseclib\Net\SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
And:
<?php
include 'vendor/autoload.php';
$key = new \phpseclib\Crypt\RSA();
//$key->setPassword('whatever');
$key->loadKey(file_get_contents('privatekey'));
$ssh = new \phpseclib\Net\SSH2('www.domain.tld');
if (!$ssh->login('username', $key)) {
exit('Login Failed');
}
echo $ssh->read('username#username:~$');
$ssh->write("ls -la\n");
?>
