If you think I've got myself into a right muddle with this business,
you're correct. Not a case of failing to rtfm, rather of too much rtfm
(or the wrong fm, perhaps).
The lan IP address in the router is 192.168.0.20, which is why I had it
in /etc/hosts.
I added the 192... business because I read in various places that you
were supposed to have this line (I didn't previously) and because
without it all hostname commands (hostname, hostname -f, hostname -s)
produce the same thing, i.e. just arcadia. But perhaps that doesn't
matter? I've taken it out at present.
The 0.0.0.0 line also came from a how-to I found on the Net, but I've
taken it out.
My /etc/network/interfaces:
----------cut--------------------------
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0
broadcast 127.0.0.255
gateway 127.0.0.1
#Router stuff
auto eth0
iface eth0 inet static
address 192.168.0.20
netmask 255.255.255.0
gateway 192.168.0.1
broadcast 192.168.0.255
---------------cut------------------------
