I'll take Harry's advice and try a different approach.

Here's what I've done today:

1) Disconnected from the internet, both machines.
2) Brought up both machines on SuSE 8.1, brought up LAN network
ping, ftp, telnet ... all work
3) shutdown one machine and re-boot with Knoppix 5.1.1
4) configure network first using "netcardconfig", fails with:
SIOCSIFFLAGS: Resource temporarily unavailable
5) shutdown and re-boot using DSL
6) configure network using "netcardconfig", ping works from both,
telnet and ftp one way (probably permissions or firewall problem)
7) shutdown and re-booted with DSL-N configure using "netcardconfig"
fails with: SIOCSIFFLAGS: Resource temporarily unavailable

In all the set ups, I've, of course, used same addresses, etc.

My conclusion? I'm missing something required in setting up networking
with 2.6 kernel(s).

What am I failing to do in 2.6 kernel setup?
