To build I generally just do the following, assuming I am starting from
scratch:
make oldconfig
make dep
make clean
make install
and that does everything
a couple of obvious questions: did you configure for networking in your
old .config you are using? did you specify the right NIC so that the
driver can start it up? What do you get when you do an ifconfig -a?
Is eth0 up or down?
Note that in older Redhat distributions I have seen cases where the
portmapper is started before the network is brought up, which will
simply cause the portmapper to crash and burn. Look in /etc/init.d/rc3.d
and note the lexical order of the filenames, and make sure network is
done first.
It sounds like you either have a config problem and have no NIC that is
working, or else something as simple as netstat -r might show that you
have no routes of any kind (although 2.1 kernels add a default route
when you ifconfig up...
