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 |
maybe a bad cable or other hardware problem?
are you pinging 10.0.0.1 |
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. |
hi sancho, were you able to solve this? i'm having the same problem!!!! argh.
any useful info would be greatly appreciated!!! |
What's in /etc/hosts?
|
oracle is other host?
can you ping from oracle? |
