Doesn't help much if one is accesssing the net via a dial-up modem.
Why doesn't the installer:
1. automatically put up a firewall rule that only allows
traffic related to the installation procedure.
2. Install a basic firewall like ipmasq to cover someone
until they can get something better up and running.
?
I'm lucky in that I have an old 486 I used with a modem to also do the
firewall. I didn't use my Etch amd64 box on the net directly until Etch
got security support.
