Have just enabled my first NFS network (yipee!) using 3 boxes, wired connections and static ip addresses. Trying to lock it down a bit more securely, but I don't seem to have either of the hosts.allow or hosts.deny files. I see in the "Linux NFS-HOWTO" pages, that apparently not all versions of linux (even recent distros) have these files. Having a hard time finding any other info on hosts.allow / hosts.deny useability for my Feisty distro. Maybe they're in an optional download through Synaptic, where I got my NFS-related programs from.
Is there a way to add these files (using vim for example) or are they not possible to add to Feisty 7.04? Portmapper doesn't refer to either file either. Also one of my next projects is to install Firestarter as my first linux software firewall (behind my WRT54G router), which begs the question of, should I even be concerned about the two files? Will firestarter do the same or better job in place of these files. So far I only have one box set as server and the other two as clients. I'd like to get the one-server setup sorted out, before I try setting each of the three boxes as both server and client. Many thanks in advance.

Problem solved. Just stumbled across a discussion, after googling. It seems there was a program called TCPD, which was included in Edgy, which didn't make it to Feisty by default. I've installed TCPD through Synaptic and now I do have the hosts.deny and hosts.allow files. So I shouldn't have a problem editing them now. Thanks.
