  • Applies to:
  • Plesk 11.0 for Linux


  1. On Plesk 11 running in Virtuozzo Containers, Firewall rules can not be updated, following errors can appear:

    Unable to connect


    safeact: safeact: /opt/psa/var/modules/firewall/safeact.confirm: No such file or directory

    After Firewall rules are accessed again, the changes were not applied

  2. Default firewall configuration drops all connections when you try to activate Firewall in Plesk runnig in Virtuozzo Container.


Upgrade to Plesk 11.5 or use the appropriate fix for Plesk 11.0: for CentOS 5 and for CentOS 6

You will need to replace the following files (do not to create the backup first):

/usr/local/psa/admin/plib/modules/firewall/ActivateForm.php                     -rw-r--r--  root root
/usr/local/psa/admin/plib/modules/firewall/BackendLinux.php                     -rw-r--r--  root root
/usr/local/psa/admin/plib/modules/firewall/FwConfigurator.php                   -rw-r--r--  root root
/usr/local/psa/admin/sbin/modules/firewall/safeact                              -rwxr-x---.  root psaadm

and this file replace in:



Issue is caused by a product issue (PPPM-561) that was fixed in Plesk 11.5 version.
