xfertool ( --help | <COMMAND> <USERNAME> [ARGS..] )
=head1 DESCRIPTION
This script is part of an automated process that WHM uses for account
transfers.
We B<do> B<not> recommend calling this script manually.
Possible COMMAND values are:
=over
=item * C<allowlogins> and C<disallowlogins>
Control the user’s ability to log in.
=item * C<blockdynamiccontent> and C<unblockdynamiccontent>
Control httpd’s handling of files with certain well-known extensions
that correlate with dynamic web content. For example, after
C<blockdynamiccontent>, C<.php> files will no longer function normally.
=item * C<setupmaildest>
Sets the user’s mail routing. Takes an additional argument that
can be C<primary>, C<secondary>, or C<remote>.
Example:
xfertool setupmaildest howard primary
=item * C<swapip>
Replaces one IP address for another in the user’s DNS zones. Takes
the source & target IP addresses as additional arguments.
Example:
xfertool swapip howard 1.2.3.4 2.3.4.5
=item * C<changenameservers>
Sets the user’s nameservers, given as additional arguments.
Example:
xfertool changenameservers howard ns1.myhost.com ns2.myhost.com
(As many nameservers can be given as needed.)
