Didn't think so :)

It looks fine.

Does it work?

Do you have any firewall doing network address translation?  If you want
fire-and-forget just use ipmasq, if you want to really understand it use
shorewall after reading shorewall-doc.

What about supplying DNS services to your network?  The easiest is to
install dnsmasq.

No.  Each *NIX has its own way, however /etc/hosts is standard.  Unix
networking was developed with BSD and was then imported by the other
*nix in various ways.  Then different *nix made automated scripts to do
the networking setup and each puts its configs somewhere different.  On
debian, its /etc/hostname and /etc/network/interfaces.

Its all well documented and hasn't changed in a long time.  Read the

I don't know what this line is for.
