I have installed recently CentOS 5 in a Dell PoweEdge 1300, this server has 3 network card, but only one is active.
The network card active is eth0 ADMtek NC100, its parameters are (manually), IP: 10.0.1.5, Default gateway 10.0.1.100, mask 255.255.255.0.
when I try ping to any machine in my network I got destination host unreachable error.
The network point, cable, and card was working before (RHEL 9), but now is not.
Thanks for your help
