As I am a big fan of open sourced products, so this might give me some bias towards this control panel as well. For your information AlternC is a set of software for hosting management on GNU / Linux.
AlternC is an online administration interface that allows management of users and web services (domains, email, ftp accounts, statistics …)
Services available and administered by the panel are:
* Domains and subdomains
* E-mail, accessible pop / imap and webmail and mail forwarding
* Web hosting with php and mysql
* Mailing lists / diffusion
* Ftp access
* Grazer to navigate the directories of the web space and adding / removing / editing files
* Site visit statistics
It seems that this project is unfortunately no longer maintained, last updated in 2008. Too bad as it’s a nice product, which is available in French, English, and Spanish, and I followed it some time ago… If you are the one who like to taste something different, then you should try this as well.
