Judging by the download link located at http://download.lxlabs.com/download/...abox576.tar.gz it would appear they only have support for servers using 32-bit processors, however with the lack of specifications or requirements listed on their website this is hard to say for sure. As for your CentOS question there generally aren't many major changes to the core operating system between minor releases (from 5.0 to 5.3) that would prevent the script from operating, so it's safe to go with the latest stable release of CentOS.
At this point I would *STRONGLY* suggest staying away from Kloxo. As the user above put it, the project is no longer under development. It's fully done for unless someone finds, decrypts and releases the source.
The state of the project is that it sits with *MASSIVE* security vulnerabilities right now. It's very easy to exploit this product. The owner committed suicide shortly after the list of exploits were published and a large customer was hacked and all data wiped. Chances are that those security issues will never get fixed.
It's actually a very tragic story, and not good in any way shape or form, but here's a link to it on their own forums.
ya I know about tht, my friend wants just simple things to be done from the Kloxo end, after completing the task we would turn off kloxo, I think hypervm is the vulnerable as it handles the server over the lxAdmin
and thanks for ur suggestions, I will pass them on to my friend
