Ok, here's what I've *heard*: My cable provider does provide static IPs.
However, it _says_ they are dynamic to discourage people from running
servers. How do people who don't need DHCP connect to the internet from
Linux, what program/script do they use then?

My soundcard is a Crystal Audio PnP...one of those soundcards built right
into the motherboard. Would you mind explaining the point of having those
hardware things, like eth0 and midi, aliased? Is that just so their name
doesn't have to be changed when a new piece of hardware is installed, or in a
similar situation?

Yes, the sound card has always been here. I left something out with my first
post, because I didn't want to make my problem sound overly-complicated
(which maybe it is). I have never gotten both sound and the internet to work
from Linux at the same time. Had to choose one or the other. I posted
something similar in the past, but it was ignored. Here's the section of
isapnp.conf that's of interest, and explained below
(CONFIGURE CSC8025/-1 (LD 3
# ANSI string -->MPU<--
# Multiple choice time, choose one only !
# Start dependent functions: priority preferred
# IRQ 9.
# High true, edge sensitive interrupt (by default)
(INT 0 (IRQ 11 (MODE +E)))
# Logical device decodes 16 bit IO address lines
# Minimum IO base address 0x0330
# Maximum IO base address 0x0330
# IO base alignment 8 bytes
# Number of IO addresses required: 2
Ok, the IRQ part...when it's on IRQ 11, the sound works. When it's on IRQ
10, the network card works. After the thing the other day where the internet
became unreachable, I changed this line back to 11 so at least I could once
again enjoy sound. I figured that fixing one problem would solve the other.
Like my olp3 doesn't work, even though arts works fine. I have a feeling
that once this network problem is solved, the olp3 one will be too. But
getting MIDI back isn't important at all compared to the internet.

How do you know all this stuff? What's your job?
