    Hello,

    I am back with another issue in cPanel-Perl Call.

    My Perl Module function has some system() command to execute

    below is a piece of code

    my $command = "/root/letsencrypt/./certbot-auto certonly --standalone -n -d ". $domainname ." -w ". $webroot;

    system ($command);

    my code always ends with below error response which is from "error_log"

    [2018-04-09 12:21:14 -0500] warn [Internal Warning while parsing unknown 13256] Can't exec "/root/letsencrypt/./certbot-auto": Permission denied at /usr/local/cpanel/Cpanel/API/CertificateDetails.pm line 80.

    I think its very chilly mistake, but i couldn't able to find so far. Can anyone help to resolve this please.

    Thanks in advance
    Rajkumar

    What user is running this perl script?

    Does that user have access to execute /root/letsencrypt/./certbot-auto?

    If the user running the perl script is an under-privileged user (i.e. not root) then they may not have access to /root/letsencrypt/./certbot-auto and you probably don't want them to have access to /root/letsencrypt/./certbot-auto.

    Hello,

    In addition to the information requested in the previous post, can you also let us know the permission and ownership values you've configured for the /root/letsencrypt/./certbot-auto file?

    Thank you.

    Hello,

    This seems more like an issue with the Perl code itself as opposed to a cPanel & WHM API function. I recommend troubleshooting this on a website where Perl coding itself is discussed (e.g. StackOverflow). Also, it looks like you are troubleshooting this particular topic on the following external URL:

    Execute certbot-auto command using perl system command

    Feel free to post the outcome here or let us know of any additional questions.

    Thank you.

    There is some access rights issues. i have tried to execute this plugin from another user which is running in root.

    Now i am moving the cPanel plugin into WHM plugin.

    Thank you.
