Nie jestem webmasterem, ale i na mnie zrobiła wrażenie szybkość reakcji Darka na mój problem. Jego kompetencja i przede wszystkim zupełnie niemodna w dzisiejszych skomercjalizowanych czasach - zwykła ludzka życzliwość dla innego człowieka. Tacy ludzie to dziś gatunek niemal wymarły...

CXIX. Secure Shell2 Functions
Bindings to the libssh2 library which
provide access to resources (shell, remote exec, tunneling, file transfer)
on a remote machine using a secure cryptographic transport.
Windows binaries may be found at
http://snaps.php.net/.
To install, download php_ssh2.dll to the folder specified
by your php.ini file's extension_dir directive.
Enable it by adding extension=php_ssh2.dll
to your php.ini and restarting your webserver.
extension_dir=c:/php5/exts/
extension=php_ssh2.dll |
Linux, BSD, and other *nix variants
can be compiled using the following steps:
Download and install OpenSSL.
If you install OpenSSL via your distribution's packaging system
be sure to install the development libraries as well.
This will typically be a package named openssl-dev,
openssl_devel, or some variation thereof.
Download and install libssh2.
Typically this means executing the following command from
the libssh2 source tree. ./configure && make all install.
Run the pear installer for PECL/ssh2: pear install ssh2
Copy ssh2.so from the directory indicated by the
build process to the location specified in your php.ini file under
extension_dir.
Add extension=ssh2.so to your php.ini
Restart your webserver to reload your php.ini settings.
Development Versions:
There are currently no stable versions of PECL/ssh2,
to force installation of the beta version of PECL/ssh2
execute: pear install ssh2-beta
Compiling PECL/ssh2 without using the PEAR command:
Rather than using pear install ssh2 to automatically
download and install PECL/ssh2, you may download the tarball from
PECL.
From the root of the unpacked tarball, run:
phpize && ./configure --with-ssh2 && make
to generate ssh2.so.
Once built, continue the installation from step 4 above.

Notatka:
You will need version 0.4 or greater of the libssh2 library
(possibly higher, see release notes).
Poniższe stałe są zdefiniowane w tym rozszerzeniu i stają się dostępne, gdy
rozszerzenie jest dokompilowane do PHP, lub załadowane dynamicznie przy starcie.

under debian, zlib-dev (zlib1g-dev at the moment) is also needed in order to install libssh2.

Trying to compile this ssh PECL extension for Mac OS X (10.4.2)
with entropy.ch's php5 distribution? Read on: PART 2:
11) Check your shell's path variable by SHELL$ "echo $PATH".
If your php5 binary directory is not listed before the standard OS X binary directory,
update your $PATH variable to list it first. Mine reads:
/usr/local/mysql/bin/: /usr/local/php5/bin/: /bin:/sbin: /usr/bin:/usr/sbin
11a) if you do not do this step, the PECL extension will link against the old
php4 version that ships with Mac OS X. You will know this by the fact that the
next step lists a server API that is different than the output of phpinfo():
My version was 20041030, Apples version was 20020429.
12) Run: phpize && ./configure --with-ssh2 && make
This will produce a lot of output and probably some warnings. If you get a note
at the end that says "Build Complete", then the process has completed
(probably successfully). The command has produced the output file ssh2.so within
the ssh2-0.9 (or whatever version) directory.
13) Check where the extension directory is located at by running the following command:
SHELL$/usr/local/php5/bin/php-config --extension-dir
If it lists some directory that actually exists, copy the ssh2.so file to this directory.
If it doesn't list a location that exists, you can either create the location, or
choose a different location and update the line in your php.ini file:
extension_dir = "./"
to point to the directory you would like to use. I chose:
extension_dir = "/usr/local/php5/extensions/"?>
14) Add the line
extension=ssh2.so
to the Dynamic Extensions area of your php.ini file.
15) Restart your web server for the extensioin to be loaded. If there are any problems, they will be written to the webserver log.
16) Check if your new ssh based streams are available by running:
SHELL$ /usr/local/php5/bin/php -r "print_r(stream_get_wrappers());"
You should get something similar to this output:
Array
(
[0] => php
[1] => file
[2] => http
[3] => ftp
[4] => compress.bzip2
[5] => compress.zlib
[6] => https
[7] => ftps
[8] => ssh2.shell
[9] => ssh2.exec
[10] => ssh2.tunnel
[11] => ssh2.scp
[12] => ssh2.sftp
)
You should now be able to do all the cool things you need to do with ssh
(like sftp scp ssh execution)! Take a look at some of the comment here for some
example scripts to test things out:
http://us2.php.net/manual/en/ref.ssh2.php
Good luck... hope that saves you my headache! :)

Trying to compile this ssh PECL extension for Mac OS X (10.4.2)
with entropy.ch's php5 distribution? Read on: PART 1:
1) Download libssh (I used version 0.11)
http://sourceforge.net/project/showfiles.php?group_id=125852
2) Unzip the directory and cd to the upacked directory in the terminal.
3) run: ./configure; make all install;
libssh should compile and place the output file in src/*.o
4) copy all headers from the include folder within the libssh2 directory to
/usr/local/include/
5) copy all compiled files (*.o) from the src folder within the libssh2
directory to /usr/local/lib/
6) Download ssh2
(I used version 0.9 with additional changes from cvs - explained below)
http://pecl.php.net/package/ssh2
7) unzip the downloaded archive.
8) version 0.9 has a conflict with an existing symbol used in some of the ZEND headers...
a change is available in cvs which renames the symbol in ssh2 to avoid the conflict
http://cvs.php.net/diff.php/pecl/ssh2/ssh2.c?r1=1.9&r2=1.10&ty=h
down load at least the 1.10 version of ssh2.c
if you decide to download a newer version, download any of the corresponding related files,
such as the php_ssh2.h header file.
9) replace the old version of ssh2.c with the new version of ssh2.c
(and any other files you downloaded).
10) From the terminal:
cd to the source directory (for me ssh2-0.9/ssh2-0.9/).

If you are using debian and looking for the openssl-dev package it is called libssl-dev.

To scan directorories with SFTP
<?php
$conn = ssh2_connect("localhost", 22);
$sftp = ssh2_sftp($conn);
$dir = "ssh2.sftp://$sftp/var/log/";
while (($file = readdir($dh)) !== false) {
echo "$file\n";
}
closedir($dh);
?>

OK, the SSH class I wrote is now available for free on the Net.
The class uses an underlying SSH implementation, and hence does not require any library to be compiled against.
It is available at savannah.cer.ch as a byproduct of project GridGramm (look in the downloads section). There are two releases available, the first one establishes a connection for each command, having a serious authentication overhead. The second release shares a master connection, highly reducing auth payload, but requires openssh >= 3.8.
They are also available from the development site at
http://savannah.cern.ch/projects/gridgramm
and come with extensive documentation and examples.
These are work in progress, and I hope to add more enhancements in the close future. But you are welcome to use them now.

Changing preferred_state setting is not always good idea (especially if you need to instal one unstable package) so I'd rather suggest using command like:
pear install -f ssh2
which forces installation of non-stable-quality packages with prefferred_state set to "stable".
