Internal Server Error 500 - subprocess exited with status 13

[Kheang]

Hi,

I made a quick plugin for WHM and put it in:

/usr/local/cpanel/whostmgr/docroot/cgi/addon_sc.cgi

Here is the content:

#!/usr/local/bin/perl

#WHMADDON:simplecommerce:Simple Commerce Admin

use lib '/usr/local/cpanel' , '/usr/local/cpanel/whostmgr/docroot/cgi' ;

use strict ;

print "Content-Type: text/html\n\n" ;

my %ACL = %Whostmgr::ACLS::default ;

if ( 'root' eq $ENV{'REMOTE_USER'} )
{
    $ACL{'all'} = 1 ;
}

if ( !$ACL{'all'} )
{
    exit ;
}
else
{
    print "<meta http-equiv=\"refresh\" content=\"0;url=$ENV{'cp_security_token'}/cgi/simplecommerce/index.php\"/>" ;
}

The plugin appears in the WHM and when I clicked on it I got the error access denied. So I went and created a simplecommerce.conf file and used appconfig to register it and it appears in the list of registered apps.

Here is the content of the .conf file:

name=simplecommerce

# This is the name that will be displayed for your application in WHM.
displayname=Simple Commerce Admin

# service that will serve this app
service=whostmgr

# Physical path: /usr/local/cpanel/3rdparty/Foo.php
# Literal URL path: $server:$port/$cpsession/3rdparty/Foo.php
url=/cgi/addon_sc.cgi

# Directory containing php.ini
# - must exist in /usr/local/cpanel/3rdparty/etc/
#phpHandler=Foo

# Features required
features=any

# This is a comma-separated list of ACLs. The logged-in user must have at least one of these ACLs in order to access your application at the URL(s) provided.
acls=all

# This is the filename of the icon that is used by the application (For example: myapp_icon.png).
icon=sc_icon.jpg

Now when I click on the plugin i get the error:

Internal Server Error

500

No response from subprocess (/usr/local/cpanel/whostmgr/docroot/cgi/addon_sc.cgi): subprocess exited with status 13 (EACCES)

I looked at the error log and it says:

Any ideas what is causing this?

Any help is appreciated, thanks!

The plugin appears in the WHM and when I clicked on it I got the error access denied.

As for the first error message that occurred, what was output to /usr/local/cpanel/logs/login_log?

Thank you.

Thank you.

Sorry the first error no longer appears because I went an registered it in AppConfig.

The first error had a message saying i could not access the script because it wasn't registered or the option to allow unregistered scripts wasn't set to On. That's why I tried registered it with AppConfig.

Is this how it should be done?
The .cgi first and then through AppConfig?
Or it's one or the other only?

Also if I want to remove it from AppConfig what do i do? Do I just delete the .conf file from the apps folder?

I still get that error 500 though.

I just looked again and I saw this:

198.48.203.84 - root [04/30/2014:18:05:57 -0000] "GET / HTTP/1.1" DEFERRED LOGIN whostmgrd: security token missing
198.48.203.84 - root [04/30/2014:18:17:38 -0000] "GET / HTTP/1.1" DEFERRED LOGIN whostmgrd: security token missing

I guess I am missing something in the .cgi script?

- - - Updated - - -

Ok nevermind its only when I try to access /cgi/simplecommerce/index.php directly when logged in.
But the login log doesn't show anything when I type the /cgi/addon_sc.cgi directly. Only that error in error_log

- - - Updated - - -

It still gives the same error when I remove all the code and put a simple print line with the configuration on top.

OK so I figured out what was the problem!

My cgi script was fine, I only needed to add a newline at the end of the file. (weird)
Now it does what it should do but brings me this error:


HTTP error 401
cgi/simplecommerce/index.php

WHM is configured to disallow execution of unregistered applications when logged in as root or a reseller with the "all" ACL. To enable this functionality you must do one of the following: Register this addon using /usr/local/cpanel/bin/register_appconfig (AppConfig), Enable the "Allow apps that have not registered with AppConfig to be run when logged in as root or a reseller with the "all" ACL in WHM" option in "Tweak Settings", or add permit_unregistered_apps_as_root=1 to /var/cpanel/cpanel.config, and run /usr/local/cpanel/etc/init/startcpsrvd

I have registered the plugin in AppConfig using my simplecommerce.conf:

name=simplecommerce

# This is the name that will be displayed for your application in WHM.
displayname=Simple Commerce Admin

# service that will serve this app
service=whostmgr

# Physical path: /usr/local/cpanel/3rdparty/Foo.php
# Literal URL path: $server:$port/$cpsession/3rdparty/Foo.php
url=/cgi/addon_simplecommerce.cgi

# This is a comma-separated list of ACLs. The logged-in user must have at least one of these ACLs in order to access your application at the URL(s) provided.
acls=all

After that I tried running the plugin again and it still gave me that error.
What am I missing in the conf file to make it work? Or do i absolutely have to turn the security features on?

 

[Kheang]

Ok i figured out my problem here too. I had to put all the url's of my scripts in the .conf file or it would not allow me to execute them.
