[RESOLVED] SSH2 not loading - The operating system cannot run %1 in Unknown on line 0

niwa3836

Help Please! Struggling to get SSH2 working on PHP in W2K3.

I want to start doing some ssh2 from my php scripts. Followed the instructions from php.net, i.e. got the PECL zip's, unzipped to c:\php5\exts
then added to php.ini: -
extension_dir=c:/php5/exts/
extension=php_ssh2.dll

then restarted apache (and the server to be sure on the next attempts!)
...Code 500! aaaarrrggghhhh

Log file below, any ideas please??

Tried loads of things, various boards talk about libraries, have tried, but not sure maybe I have that bit right.

Is c:\php5\ the folder you installed PHP in? Do you see several .dll files in that folder (especially libeay32.dll)?

EDIT: Can you verify that php_ssh2.dll is in the folder c:\php5\ext\ ?

Hi Brad, Many thanks for the response, was starting to lose hope 🙁

Yes can confirm that all the PECL dll's are in that directory. Have checked and the entire contents of the GnuWin32 bin directory is also copied into this directory (i.e. contain libeay file + ssleay etc. Have also copied them into Program Files\php too and made sure PATH has the Program Files\gnuwin32.
Not sure I have this bit correct though? I downloaded the openssl-0.9.7c-bin.exe from libssh group and installed on server.
Have tried many combinations of php.ini and still not work. Reboots each time to confirm.

Still get error ....

The only file you should need to worry about is ssleay32.dll.

You mentioned \Program Files\PHP\ ... is this where you initially installed PHP? If so, why did you create c:\php5\ ?

All that's needed to get this extension to work is a) verify the path to php_ssh2.dll is correct, b) verify that 'ssleay32.dll' exists in the root of your PHP directory, and c) ensure that the root PHP directory has been added to the system's PATH environment variable (restarting is require if you change the PATH variable).

Hi Brad, once again thanks for the reply, but still no joy....
"All that's needed to get this extension to work is a) verify the path to php_ssh2.dll is correct, b) verify that 'ssleay32.dll' exists in the root of your PHP directory, and c) ensure that the root PHP directory has been added to the system's PATH environment variable (restarting is require if you change the PATH variable)."
a) Tried many combinations in php.ini
;extension_dir=c:/php5/exts/
;extension_dir="c:\php5\exts\"
;extension_dir="c:\Program Files\php\"
extension_dir = "./"
are just a few that I have tried. This must be working as when I rename the php_ssl2.dll it then throws a different error like not found.
b) ssleay32.dll is absolutely everywhere to make sure its found. The only interesting thing is that I acquired the file from dll-files.com as it didnt seem to be packaged anywhere around the php sites like www.php.net. I did get the other dll's from http://sourceforge.net/projects/libssh2/ (but again why no ssleay32.dll? Maybe I should try and acquire another version, Can you recommend a site or do you have a copy that you could email / ftp / yousendit.com site maybe?
c) PATH variable includes c:\program files\php\ and c:\program files\gnuwin32\bin\
both have all the files in, I just splatted everywhere for safety.
I know the PATH must be "working". In cmd prompt I type openssl.exe and it runs, the file appears in both directories above.

Please keep those ideas coming, I seem so close and yet so far! Have I missed a re-complile stage (bearing in mind this is windows), have i got the right ssleay32.dll? Is there any more debugs I can acquire for help? Do I need to PECL install or something too (i have also "re-installed 5.2.5 with SSH" as PECL).

Help!
Really many thanks!
Nigel

I would recommend uninstalling PHP completely (you can save your php.ini file, but delete all other php-related files). Also clean up the ssleay32.dll mess - delete it from all the locations you copied it to.

Then, redownload the .zip package from php.net and re-install PHP to a central location (I usually use "c:\php"). Then verify that the extension_dir path is correct, copy the php_ssh2.dll to that directory, update the PATH variable to reflect the new location of PHP (and get rid of the old ones if you haven't already), restart the system, and try it again.

Brad, Tried all of that, and also tried W2K pro too, but no joy. you didnt comment on the openssl stuff, do you have experience of that. I have installed, but there is no instructions for PATH etc, although again have tried many combinations. I cant be sure that I have a good version of ssleay32.dll. The openssl site provides the others but not this one. Tried another version of ssleay32.dll from vmware, which was a quarter of the size that I had found elsewhere, still same error. The openssl install also seemed to create libeay32.dll files that are different sizes to what I have got. Have you got a current installation working of this that I can compare file sizes / versions etc, including OS? Thanks again for your help.

I didn't install any other software other than PHP to get SSH2 to work on my Windows XP laptop. I just had to download the php_ssh2.dll from the PECL pack at php.net, but other than that, everything else came with PHP and all I had to do was add an extension= line to php.ini.

Hi, just look at the same problem

" ....PHP Warning: PHP Startup: Unable to load dynamic library 'c:/php5/exts/php_ssh2.dll' - The operating system cannot run %1.\r\n in Unknown on line 0...."

What about look for execution rights in Security Tab of the PHP installation Folder ?

Cheers

bradgrafelman

The only time you'd need to worry about execution rights is if you're running PHP with IIS.

Otherwise, verify that php_ssh2.dll exists in c:/php5/exts/, verify that ssleay32.dll and libeay32.dll are in c:/php5/, and verify that c:/php5/ was added to your system's PATH environment variable (and that the system was restarted after making this addition).

Thanks for the response, but I seemed to have fixed this Friday but havent had chance to gather the full response. Here for the record is what I have found.

First I removed everything, make sure all originallly apache directories are gone and all the PHP directories too. I have changed from the SSL version to the NON SSL version of apache httpd. So installed that first.

Then I installed php 5.2.5 into directory c:\php\
did this as some issues described with spaces in the path names.
BUT ONLY INSTALL OPENSSL AND SSH2 OPTIONS (AND PEAR INSTALL) ONLY.

Then path sure your path includes C:\PHP\

The installation seems to do a good job (check by doing PATH in a CMD window). HOWEVER it will not take affect intill you reboot.

Then I found that I left some old (and BAD) ssleay32.dll's in c:\windows\system32\ so renamed those to old as most programs that need this install it local in the program files directories. Again another reboot and voila.

If you get stuck try post a question hear and I will try and help, otherwise try my person e mail address which is (removed by moderator - sorry!). Good Luck
