Aargh!!! Not routing to local subnet
I have a freshly installed RedHat 7.2 (very basic install, at that) and thought I had the network configured right, until I try to hit any computers besides localhost. Some details:
localhost (127.0.0.1)
oracle (10.0.0.253) {our problem host}
LAN: 10.0.0.0/24
I have a host on the network who are fully connected to the LAN and the Internet. When I try to ping them:
From 10.0.0.253: Destination Host Unreachable
From 10.0.0.253: Destination Host Unreachable
From 10.0.0.253: Destination Host Unreachable
From 10.0.0.253: Destination Host Unreachable
ifconfig:
eth0 Link encap:Ethernet HWaddr 00:08:C7:F4:D1:43
inet addr:10.0.0.253 Bcast:10.0.0.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Interrupt:11 Base address:0x6200
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:520 errors:0 dropped:0 overruns:0 frame:0
TX packets:520 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:49340 (48.1 Kb) TX bytes:49340 (48.1 Kb)
route -n:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 10.0.0.1 0.0.0.0 UG 0 0 0 eth0
As you might guess, 10.0.0.1 is the address of my gateway, hence the default route of 0.0.0.0.
With this configuration, why am I not able to hit other hosts? There is no firewall rules set on any of my boxes; I have checked physical connectivity (link light on the nic and the switch on all ports) and don't know what it could be. I even deleted and recreated the route entry for the 10.0.0.0 subnet and recreated it. Any ideas?
Thx

i've tried a couple of cables; i am pretty sure the error message isn't referring to physical media, or it wouldn't be complaining about the lack of a route to host.
i've tried pinging 10.0.0.1, 10.0.0.3, and 10.0.0.251, 3 hosts on my local subnet that are live. same error.
