GNUPanelGNUPanel is a completely free (GPL) replacement for proprietary web hosting automation software. GNUPanel is under development, focusing on translation efforts that permit the entire free software community to participate. Currently, GNUPanel is Debian-centric, however, a distro-agnostic approach is planned.
It is written mainly in PHP 5 and initially designed to run on 32 or 64 bits Debian GNU/linux.
The administrator can manage a web hosting server, create public and private hosting accounts, accept Paypal, Cuentadigital and Dineromail payments, send messages to users, create redirections, use the integrated support ticket system, control bandwidth, disk space and define policies for accounts suspension.
The users can use the regular functions to create mail and FTP accounts, databases, directories protection, etc. In addition they can make payments, place domains in parking and activate or deactivate in each subdomain PHP directives like safe_mode and register_globals.
GNUPanel stores its configuration on a postgreSQL 9.1 database and provides three web interfaces with SSL access at user, reseller and administrator level.
Kloxo - Even if it has bugs it’s easy to use and install. Kloxo allows the host administrators to run a combination of lighttpd or Apache with djbdns or bind, and provides a graphical interface to switch between these programs without losing data. Kloxo Enterprise can transparently move web/mail/dns from one server running Apache to another running lighttpd. It is also known as a good free alternative to cPanel hosting control panel.
