Can't access anything on LAN except router


Maybe I just can't see the forest for the trees but this has me stumped. My machine cannot access any local hosts except the router and no host can acess my machine including itself.

pinging 192.168.0.1 works (this is my router)
pinging 192.168.0.2 hangs (this is a LAN host same for others)
pinging 192.168.0.3 hangs (this the local host)
pining 127.0.0.1 hangs (this is really strange)
pinging any WAN address works.

Here is my netstat -rn output:

Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0

It has been a long time since I've had to play with routing but seems correct to me. FWIW, here is my ifconfig output as well:

eth0 Link encap:Ethernet HWaddr 00:10:5A:C6:A6:C6

This stuff used to be second nature for me but I guess I'm getting senile. Can someone see what is wrong with my network configuration? TIA.

I would say there is something really wrong if you cant even ping the loopback.

Do the other computers on your network have firewalls? Maybe they are blocking any ping/icmp requests?

Thanks for the reply. Mandriva 2007.0 has been giving me fits since I installed it. As a desperate grab for a straw I did a reboot and that seems to have fixed at least that problem.
