Ifconfig(s):

Seems that the non-SMP kernel works fine.
Here is the ifconfig;
[root@localhost root]# uname -r
2.6.6-1.435.2.3
[root@localhost root]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:02:E3:1D:3F:32

[root@localhost root]#




But the SMP kernel has issues;

[root@localhost root]# uname -r
2.6.6-1.435.2.3smp
[root@localhost root]# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0

[root@localhost root]# ifconfig -a

[root@localhost root]#



Then I did the static IP number thing, but had/have a communication problem;

[root@localhost root]# ifconfig eth0 down
[root@localhost root]# ifconfig eth0 192.168.0.49 netmask 255.255.255.0 broadcast 192.168.0.255
[root@localhost root]# ifconfig eth0 up
[root@localhost root]# ifconfig

[root@localhost root]# ping 192.168.0.103
