Getting Error During Adding WHM Plugin

[madihrb]

Hello, I am planning to create my own whm plugin.

So I got an example plugin from some forums and I uploaded it to

addon_hello.cgi to /usr/local/cpanel/whostmgr/docroot/cgi

Now, I can see my plugin in Plugins section of WHM.

But when I click this addon from whm I recieve the following error:

open3: exec of /usr/local/cpanel/whostmgr/docroot/cgi/addon_hello.cgi failed at cpsrvd-ssl.pl line 5654

The code of plugin that I have uploaded is following:

#!/usr/bin/perl
#WHMADDON:helloworld:Hello World <b>Example</b>
###############################################################################
#	This is an example hello world WHM plugin feel free to modify it as you see fit
###############################################################################
# Load general use case perl modules
use lib '/usr/local/cpanel';
use Cpanel::cPanelFunctions ();
use Cpanel::Form            ();
use Cpanel::Config          ();
use Whostmgr::HTMLInterface ();
use Whostmgr::ACLS          ();
###############################################################################

print "Content-type: text/html\r\n\r\n";

# Check user has root permissions
Whostmgr::ACLS::init_acls();
if ( !Whostmgr::ACLS::hasroot() ) {
	# User is not root, tell them where to go
	print "You need to be root to see the hello world example.\n";
	exit();
}

# Parse input parameters from GET and POST into $FORM{} for later use
my %FORM     = Cpanel::Form::parseform();

# Print a WHM Header
Whostmgr::HTMLInterface::defheader( "Hello World Example Plugin",'/path/to/logo.gif', '/cgi/addon_helloworld.cgi' );

# Print General Output
print "<p>Hello world indeed...</p>";

# End Example

Please help in this regard and help me to resolve the error I am recieving.

Although for me the code of plugin is ok.

Is that any other configuration needed ?

Is this .cgi file owned by root:root? If not, please make it so .

[madihrb]

Yes it is owned by root.

But still i get the error.

[cPanelDavidG]

Hmm, maybe your '/path/to/logo.gif' parameter is causing the script to cease functioning?

[madihrb]

I changed it to:

# Print a WHM Header
Whostmgr::HTMLInterface::defheader( "Hello World Example Plugin",'', '/cgi/addon_helloworld.cgi' );

But still I am getting the same error.

[madihrb]

Also, I removed the header.

The same error is comming.

[cPanelDavidG]

Also, I removed the header.

The same error is comming.

Hmm, your code with that modification is working on my test server. Did you chmod +x the .cgi script?

[madihrb]

I tried but still the same error I am recieving:

To test I added only two lines:

#!/usr/bin/perl
#WHMADDON:bhai:Hello

Its name is addon_bhai.cgi.

Its permission is -rwxr-xr-x.

It is owned by root i.e user=root & group=root.

It is uploaded to /usr/local/cpanel/whostmgr/docroot/cgi/.

open3: exec of /usr/local/cpanel/whostmgr/docroot/cgi/addon_bhai.cgi failed at cpsrvd-ssl.pl line 5654

I don't know why it is showig in my system.

What happens when you execute this shell script manually from the command line?
