kernels 2.0.x, 2.2.x and networking

[Jor-el <jorel@ibm.net>]

Hi,

	I just shot myself in the foot, when trying to reach for the
stars...

	I was trying out the 2.2.5 kernel on my Slink install. Before I
saw the page on running 2.2 by Anthony Towns (did I get the name right?),
I had noticed that when bring up my 2.2 kernel, my route using lo was not
coming up. And I couldnt bring it up manually either. The messages that I
was getting indicated some kind of syntax error - which was strange, since
I was booting off of the same rootdisk used by my 2.0.36 Slink install.

	Anyway, when I discovered Anthony's page, I went and downloaded
the new netbase and installed it. This of course required the new libc6
(otherwise it wouldnt configure), and which required apt version 0.10 (and
which I couldnt find - what I found was apt version 0.3x [x = something
or the other]). Anyway, everything is installed, and now my 2.2 kernel
still doesnt produce a route for lo, but worse (oh horrors!) my 2.0.36
kernel now produces the following 'ifconfig' output :

eth0      Link encap:Ethernet  HWaddr 00:20:78:15:E3:9E
          unix addr:  Bcast:  Mask:
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0
          Interrupt:10 Base address:0x1200

lo        Link encap:Local Loopback
          unspec addr:00-00-00-00-00-00-00-00-00-00-00-3B-01-40-02-00
Bcast:00-00-7F-FF-FF-FF-00-00-00-00-00-3B-01-40-02-00

          UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0


	This is what a working 'ifconfig' setup looks like (on my Redhat
system - same machine) :

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
          UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0
          TX packets:0 errors:0 dropped:0 overruns:0

eth0      Link encap:10Mbps Ethernet  HWaddr 00:20:78:15:E3:9E
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:5 errors:0 dropped:0 overruns:0
          TX packets:5 errors:0 dropped:0 overruns:0
          Interrupt:10 Base address:0x1200 

	Save me!
