in order,
1) /etc/network/interfaces looks a lot like this:
# The loopback interface
iface lo inet loopback
# small sub-net (mask 248)
iface eth0 inet static
address 192.168.7.84
netmask 255.255.255.248
network 192.168.7.80
broadcast 192.168.7.87
gateway 192.168.7.81
2) i've installed (apt-get) "ipmasq", plain vanilla out of the
box (no tinkering with potato's ipchains other than that) and
3) i've installed the 'task-dns' package, but as straight ip
addressing gets lost, i don't expect my dns to work properly
either.
on the other hand, my /etc/resolv.conf looks like:
nameserver 127.0.0.1
nameserver 63.64.9.19
nameserver 63.64.9.11
but the externals won't be reached until a ping can bounce,
right?

i thought that might be the case. i don't know enough to know
what direction to look in, so i didn't want to waste bandwidth
with random extranea. :)

dang. it's at work, and not connected to anything (hence the
trouble) so cut and paste ain't so easy at the moment. i'll do
that next workday if i get a chance edgewise.

yes. 0% packet loss, at 0.1-0.2 ms each. <newbie>curious -- it
sounds like information can be gleaned from that, and i'm
curious: how?</newbie>

DEBIAN NEWBIE TIP #69 from Will Trillich <will@serensoft.com>
:
Preparing to UPGRADE POSTGRESQL? If you have a second machine on
your network that you can tinker with, do your upgrade there,
first: once tested, you can just have your current applications
link to the remote database through the network:
psql -h 192.168.2.17 myDB
or in perl,
$dbh = DBI->connect('dbi:Pg:dbname=myDB;host=192.168.2.17');
(You may need to tweak your 'host-based access' settings in
/etc/postgresql/pg_hba.conf, first.) Once you're satisfied that
all is well, upgrade your main server. No down time!
See "man psql" and "man DBD::Pg" for details.
