We've found a bug in the recently released 2.2.1 version of Links SQL that can cause ftp:// link verification to fail (FTP link verification is only available if the Net::FTP module is installed). The fix is very simple - on approximately line 360 of admin/Links/Tools.pm, you'll find a line:
$user ||= 'ann
The extra "n" should be removed, so that the line looks like:
$user ||= 'anonymous';
The 2.2.1 package available for download as of this post contains this fix.
