Hello,
I am completely new to this area.
In fact, I would like to install a server on a virtual machine (I know it will not be active all the time) I reread with the Internet via the NAT setting. All on VMware Player (latest version).
My goals are:
-how a server that hosted my web site data (I have a subdomain on dyndns.fr: h2o64.dyndns.fr)
a maximum-security
-my site not rowing all the time
-can be a server for email en@h2o64.org
-the address of my website is www.h2o64.org

If you have any questions then say I am at your disposal.
I should point out that starting from scratch ie I have the installation CD of Ubuntu Server 11.10's all.
