Thank you Bill for your suggestions. I turned off the service, and I manually created /etc/sysconfig/network-scripts/ifcfg-eth1 since it did not exist only eth0 existed and I did not put in anything special only
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
# Ethernet controller: 3Com Corporation 3c905 100BaseTX [Boomerang]
DEVICE=eth1
HWADDR=00:60:97:C5:2A:C3
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# nVidia Corporation nForce2 Ethernet Controller
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:0E:A6:42:59:AF
IPV6_AUTOCONF=yes
ONBOOT=yes
[root@localhost ~]#
dhcpd was off and this is what I got with the two commands :
[root@localhost ~]# netstat -ta
