I can't give you any hardware advice on this because it is a Mac, but the
first thing you should check is that the kernel recognizes eth0. As I had
mentioned yesterday, networking is brought up by the scripts when you
transition from single to multi-user mode. The lo interface is just a
loopback in the kernel. I suspect that somehow the scripts are not being
executed. Different releases of Linux assign different run levels for thing.
SuSE, for example uses run level 2 for command line and run level 3 for
GUI, Red Hat uses 3 and 5 respectively. The location of the scripts is in
the init.d directory which can be a subdirectory of /etc or /etc/rc.d or
/sbin depending on the distribution. There are symbolic links to these in
directories rcn.d, where n == run level. Again, the rcn.d directtories are
usually in the same directory as init.d, or subdirectories of init.d.
(Confusing, but its different with each distribution). It will look l;ike
lrwxrwxrwx 1 root root 10 Feb 8 16:23 K40network ->
lrwxrwxrwx 1 root root 10 Feb 8 16:23 S05network ->
When transitioning to multi-user the specified or default run level will be
executed. The symlinks in the rcn.d directory wil be executed. The Knn
scripts will be executed with the stop parameter, and the S scripts will be
executed with the start parameters. Generally, the network script will
bring up .
On SuSE, lo is brought up by the boot script and on Red Hat via the network
script execuing /etc/sysconfig/network-scripts/ifcfg-lo.
You might just try bringing lo up by hand:
/sbin/ifconfig lo 127.0.0.1 netmask 255.0.0.0 up
This should bring up the local loopback interface.
The symlinks will look like:
