=head1 modify-database-hosts.pl
Adds or removes an allowed MySQL host for some or all domains
This command can change the remote hosts that are allowed to login to the MySQL
databases owned by some virtual servers and all their sub-servers. The domains
to modify are selected with the C<--domain> flag, or you can select all (with
MySQL enabled) with the C<--all-domains> command-line parameter. The
C<--type> flag must be given, and followed by a database type to modify.
Currently, only C<mysql> databases support configuration of allowed remote
hosts.
To add a remote system to allowed list, use the C<--add-host> flag followed
by a hostname, IP address or IP pattern like I<192.168.1.%>. To take away
a host, use C<--remove-host>. To clear all existing remote hosts and specify
a new list, use C<--set-host>. All of these flags may appear multiple times,
but if you use C<--set-host> the other two cannot be used.
Access from the system running Virtualmin is always granted, and cannot be
removed.
