Ive been using SAMBA but I'm not happy with its performance (slow, and drops out completely, requiring restart of the SAMBA service). So I'm trying to set up NFS instead. I got it up and running as I can now browse NFS shares from my other Ubuntu machine. But I have several machines on my network, and wish to use all of them with NFS, which means the server needs to be configured to allow NFS connections with all hosts on my network. This is where I'm stuck. So lets say my servers IP address were 192.168.200.2 and the subnet mask were 255.255.255.128. And lets say I have 10 machines on the network. How would I go about configuring my exports file so NFS shares work on all 10 machines? Do I have to spell each one out, or can I specify an address range for each share? I've never used NFS before, so I'm pretty new to this. Any help would be greatly appreciated.

Nevermind, figured it out. I found an easy way to calculate the subnet for my network. Basically I just used a subnet calculator. I'm posting the link for anyone who is interested.
