I'm setting up a Ubuntu Sandbox to play in. I have run thru the installation process via the Ubuntu Server Guide (Great documentation - easy to follow) Now I would like to configure the system to do some work. The follow services are needed.

DNS - Intranet
Web - Intranet (Multi sub-sites for Website Dev)
FTP - File transfer to each site
VPN - Internet access to Windows systems
NFS/SAMBA - File Share for both Windows and Linux systems

Do I create threads for each of services I have questions/issues with? Or post all to one thread?
