Hi everybody:

I have a Moodle 2.0 and Mahara 1.3 integrated via SSO installation.

The SSO works fine, but I´m having some trouble while trying to export content to Mahara.

I get this error while trying to save a forum post to Mahara:

"Failed to start communication with remote server: remote server error: code: , message: Cannot find unzip executable"

Any ideas welcome.

Thanks in advance!

Hi Tomas,

as I've told you in the Spanish forum (I'm reposting it here in case someone else has the same problem in the future ;-), you need to install a unzip (and ideally zip too) executable in your Mahara server. A command line zip/unzip, not something like Winzip, 7zip, etc. And tell Mahara the path of both of them, in config.php with the options

$cfg->pathtounzip = '.....';   // absolute path to unzip executable
$cfg->pathtozip   = '......';  // absolute path to zip executable

Saludos.

Iñaki,

Thanks for your response, the problem is that my config.php file does not have those paths.

Nevertheless I added them to both Moodle and Mahara config.php file and made a web server restart with no results at all.

P.D.: I have Moodle 2 in the server, maybe the procedure is different?

P.D.2: I see in my /usr/bin folder both the zip and unzip utilities.

Cheers!

Tomas

Iñaki:

• /usr
•  /usr/bin

Have this privileges drwx-rwx-rwx

and 

• /usr/bin/zip
• /usr/bin/unzip

Have this privileges:

-rwx-rwx-rwx

I gues that with those values both the directories and files should be executed.

Is there a way to check if I have SeLinux or AppArmor installed in my server?

Thanks!

You can check if you have AppArmor installed and enabled in your system by executing the following command as root:

/usr/sbin/apparmor_status

You could get something more or less similar to this if you have it installed and enabled:

apparmor module is loaded.
5 profiles are loaded.
5 profiles are in enforce mode.
   /sbin/dhclient3
   /usr/lib/NetworkManager/nm-dhcp-client.action
   /usr/lib/connman/scripts/dhclient-script
   /usr/sbin/mysqld
   /usr/sbin/tcpdump
0 profiles are in complain mode.
1 processes have profiles defined.
0 processes are in enforce mode :
0 processes are in complain mode.
1 processes are unconfined but have a profile defined.
   /usr/sbin/mysqld

You can check if SELinux is installed and enabled by executing the following command as root:

sestatus 

If installed and enabled you would get something similar to this:

SELinux status:         enabled
SELinuxfs mount:        /selinux
Current Mode:           permissive
Policy version:         16

You should consult AppArmor or SELinux documentation to allow the web server execute /usr/bin/unzip  if you have any of them installed.

Saludos.

Hi,

In case this helps anyone, this was resolved for me by simply making sure when specifying $cfg->pathtounzip and $cfg->pathtozip in config.php (assuming your Mahara installation is on Ubuntu / Linux), I didn't add the .exe extension for zip / unzip.  You should have it as follows:

$cfg->pathtounzip = '/usr/bin/unzip';
$cfg->pathtozip   = '/usr/bin/zip';
