vp-usb-lock is a Linux kernel driver and PAM module that utilizes the PC wireless USB lock and makes it possible to use it as authentication method for your Linux box. It is easy to install, but needs access to the sources of the kernel and PAM to build correctly. It has been tested under Fedora Core 2 with a custom made 2.6.7-1.494.2.2 kernel, but it should also work with other kernel versions and distributions.

It works with vqadmin, qmailadmin, vqregister, sqwebmail, and courier-imap. It supports MySQL, Sybase, Oracle, LDAP, and file-based (DJB constant database) authentication. It supports SMTP authentication combined with the qmail-smtp-auth patch. It supports user quotas and roaming users (SMTP relay after POP authentication).
Virtual Qmail Web Administrator (VqAdmin) is a CGI Web program to allow virtual email hosting machine administators to add, delete, and modify virtually hosted email domains and users using vpopmail. Authentication is provided by ACLs and the Apache htpasswd method. Machine Administrators can add/delete virtual email domains, and tech users can admin user email accounts such as setting passwords, disk quotas, and privileges.
