When the system starts, this is what it does:

* Starting eth0
*  Bringing up eth0
*   dhcp
*    Running dhcpdc ....                                              
                        [ !! ]
* Starting cupsd ...                                                  
                          [ ok]
* ERROR: Problem starting needed services.  "netmount" was not started.
* ERROR: Problem starting needed services.  "samba" was not started.
* ERROR: Problem starting needed services.  "sshd" was not started.

Sorry for any typos - I was transposing from screen to screen without
looking at my laptop's keyboard or screen.  Dysgaphia...  does wonders
to the brain ; )


I tried this:

localhost ~ # dhcpcd

and it did nothing.  I then annexed " eth0" to that (I figured it
couldn't hurt to try) and it didn't do anything.  dhclient says that
the command isn't found.

ifconfig -a reveals something very interesting...

eth1: Link encap:Ethernet HWaddr 00:04:5A:8c... the rest of the MAC
address, I think
Interrupt:11 base address:0xa000

eth2: (the same)
interrupt:10 base address:0xc000

So, I take it that my NICs are detected and properly installed...

I just piped the same command through less to see the first bit:

eth0 Linuk encap: UNSPEC HWaddr 00-11-06-00-00-00-39-CA-00-00-00-00-00-00-00-00
and then some packet stats which all read zero.

That isn't a valid MAC, is it?  I don't think this eth0 is really
valid.  So now...  how do I kill it and substitude the apparently
working but not configured/used eth1 and eth2?

BTW: thanks for those commands - I didn't know about them.
