On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Plesk for Linux kb: technical ABT: Group B

Applicable to:

  • Plesk for Linux

Symptoms

  • Email notifications are received daily:

    CONFIG_TEXT: run-parts: /etc/cron.daily/imunify360-firewall exited with return code 127

    CONFIG_TEXT: Cron root@example.com /usr/bin/flock -n /var/run/shrinker.lock /opt/alt/python35/bin/python3 /opt/alt/modsec-sdbm-util/bin/shrinker.py > /dev/null
    flock: failed to execute /opt/alt/python35/bin/python3: No such file or directory

    CONFIG_TEXT: /bin/sh: /opt/alt/python35/share/imunify360/scripts/update_components_versions.py: No such file or directory

  • Imunify360 is not installed: the extension does not appear in Plesk at Extensions > My Extensions.

Cause

The daily task from previously installed Imunify360 was not removed.

Resolution

  1. Connect to the Plesk server via SSH.

  2. Remove the Imunify360 cron tasks:

    • on CentOS/RHEL-based distributions

      # rm -f /etc/cron.daily/imunify360-firewall

      # rm -f /etc/cron.d/waf_configurator

    • on Debian/Ubuntu-based distributions

      # apt-get purge imunify360*

    Having the same issue here, the suggested solution: apt-get purge imunify360* 

    does not solve it (still receiving daily cron emails)

    Hi Bas de Bruin

    You can check what other Imunify cron jobs are still running with the following command:

    # grep -ir imunify* /etc/cron*

    Then you can remove the files from the paths mentioned in the output.

    Hi @...

     

    Thank you. My UNIX knowledge is a little rusty si that why I am using Plesk. Apparently:

    - un-installing Imunify doesn't delete these cron entries

    - Plesk will not show these cron entries in the Scheduled tasks

    Hi Bas de Bruin

    >- un-installing Imunify doesn't delete these cron entries

    Yes. Removing the extension does not remove the cron tasks. It is needed to remove them manually.

    >- Plesk will not show these cron entries in the Scheduled tasks

    Some of the package files are installed on the OS directly and thus not managed by Plesk, such as the cron jobs.
