Free technologie software for linux

Domain Technologie Control (DTC) is a GPL control panel for hosting. Using a web GUI for admin and accounting all hosting services, DTC can delegate the task of creating subdomains, email, and FTP accounts to users for the domain names they own.
DTC manages a MySQL database containing all the hosting information. It has support for many programs (bind 8 and 9 and compatibles, MySQL, Apache 1.3, php4, qmail, postfix 2, courier, dovecot, proftpd, webalizer, mod-log-sql, etc.) through config files and/or MySQL plugins (when the service is non-critical).
Domain Technologie Control project can also generate backup scripts, calculation scripts, and config files using a single system UID/GID and monitor all traffic accounting per user and per service. Since version 0.12, DTC is fully skinable and translated in 8 language (Chinese, English, Spanish, French, Deuch, German, Italian and Russian).
DTC has been tested and works well with FreeBSD, Debian stable testing and unstable and now handles SBOX cgi-wrapper to provide chroot environment to users binaries. There is a RPM for DTC that has been done under RedHat 7, but its not well tested (I need feedback on this one as I dont use RPM based distributions myself).
Enhancements:
- This version adds support for Xen VPS connecting to dtc-xen (SOAP server) and the cyrus.
- It includes support tickets, renewal with email reminders, a new, easier to understand layout, (unfinished) import/export functions, domain parking (for DNS, Apache, and mail), daily stats (instead of each month), and some more package installers (Joomla, Vtiger, WANewsletter, and drupal).

DTC-Xen is a Xen dom0 application and SOAP server (with authentication and SSL) through which a Domain Technologie Control (DTC) Web hosting panel can be connected to manage your VMs.
It supports remote start, shutdown, and destroy of your virtual machines, as well as SSH login in the physical console (with the ability to remotely change the SSH password).
DTC-Xen also displays CPU and network graphs that can be used to analyse the performance of your virtual machines.
Enhancements:
- There was a bug in the calculation of the MAC address when calling changeBSDKernel to be able to change the kernel between NORMAL and INSTALL.
- Its now resolved.
- Be sure also to update DTC to the latest CVS version.

mysqmail is a replacement for the qmail standard checkpasswd that performs authentication with a MySQL table.
After authentication, mysqmail sets up two environment variables that it uses to perform traffic accounting.
For SMTP, it provides an alternative logger for the qmail-send program. Instead of logs, it writes the traffic to a MySQL table for the related domain.
MySQmail helps keeping all the qmail MTA login and trafic informations in a database.
This tool was written mostly to work with Domain Technologie Control (DTC). MySQMail is not mandatory for DTC, but its a way better to have it.
I needed to have qmail accounting, so I had to write couples of binaries. Fortunatly qmail is modular and its realy easy to make some add-ons. Here is what MySQmail package will add to qmail: pop will use MySQL backend for password, and both
SMTP and POP will have trafic logged into MySQL by mailbox.
Enhancements:
- This version adds support for a new score board table that allows for real-time bandwidth recording in MySQL.
