Are you still having this issue, and are you saying it works through CLI but not when accessed from a browser?

I’m using version libssh2-1.2.7 but am having to run the script error
by apache. PHP works fine.

Error menssage:

Is this with ssh2_exec that is failing?

Worked great for me on a Centos 5.4 x64 server. However the ssh2 functions only seem to work for php cli not php through apache annoying as scripts through apache don’t error either they just dont run the commands. any ideas?

Interesting, seems like that could have saved me a lot of headaches, I will probably use that library in the future with other projects.

Thanks!

I spent days trying to get libssh2 installed and when I succeeded I found that it doesn’t even work half the time, anyway. ssh2_exec() returns prematurely very frequently and not even calling socket_set_blocking() helps. I then turned to phpSecLib and it works like a charm:

http://phpseclib.sourceforge.net/

Maybe it’ll help you as well.
