This is just the hosts file for one of the machines ...
What are you intending to accomplish with the acampbell.org.uk and
accampbell.uklinux.net entries?
Each entry after the IP address on a line should be an identifier for
this machine and this machine only.

Well, scp is ssh's file transfer tool. If your router also acts as a
firewall *and* you have particular directories you care about, you might
consider using NFS or Samba for file sharing. Do *not* use NFS or Samba
unless you have a firewall of some sort in between those machines and
the world at large.
(Actually, I strongly recommend configuring a firewall, regardless of
what services you choose to run. Close every inbound port that you
don't absolutely need.)
