SSH2 Extension for PHP-FPM

nimdy

Hi all,

Does anyone know how I can get the SSH2 extension working with PHP-FPM (LEMP)? I've googled it but can only find people asking the question with little or no answers. I'm trying to get Ajaxplorer working on my VPS.

Thanks.

@nimdy - What distro are you running? On deb-based, all you need is:

install libssh2-1-dev libssh2-php
php -m |grep ssh2

The second command will return ssh2 if it's installed successfully.

Debian. Thanks that worked a treat. I thought it was a conf file change or file download that I was looking for, not a simple apt-get

Thanks.

No worries :P

Just keep in mind that php ssh2 is a bit of a pain if you're going to use RSA. Try as I might, I could not get any RSA key with a passphrase to authenticate. RSA keys with a blank passphrase worked just fine, however.

If you're wanting to use a key, go with DSA. So far that's worked like a champ for me.

Its probably better todo it via "pecl install ssh2-beta", it automatically puts the extension file in the right place.

I also made a tutorial on installing it in a few minutes under CentOS, its a similar process for Debian, but using apt-get and the same packages (different names however).

@Daniel - have you ever run into the RSA problem I described above?

PHP-SSH2 is an absolute nightmare for RSA, the extension itself has not been updated for a while and has quite a lot of bugs.

A library was created to solve this, using a pure PHP implementation for SSH2 connections, I tried using it, but compared to the extension, its fairly hard to use.

Aaah, lovely. I'll look into that when I have some free time, thanks for the info.

No problem. My Software (PiePanel), takes advantage of the SSH2 module, although some changes in order to speed it up.

@Daniel - what makes phpseclib hard to use? I found it's OOP API easier to use than PHP-SSH2's API.

How would you do the API out of curiosity?
