Hi All,
In cPanel we can restrict a user to create certain domains.This feature can be enabled using tweak settings.
To view the common domains listed in cPanel & WHM we can check the file
#vi /var/cpanel/commondomians
To add the list of domain names that should not to be used by users first create a file under
/var/cpanel/commondomainsseparate the domains name by entering in newline
Before doing this make sure that Under
tweaksettings in WHM check
Prevent cPanel users from creating specific domain That's it
