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 works (this is my router)
pinging hangs (this is a LAN host same for others)
pinging hangs (this the local host)
pining 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 U 0 0 0 eth0 U 0 0 0 eth0 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
inet addr: Bcast: Mask:
inet6 addr: fe80::210:5aff:fec6:a6c6/64 Scope:Link
RX packets:272639 errors:0 dropped:0 overruns:0 frame:0
TX packets:80459 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:220567360 (210.3 MiB) TX bytes:5759599 (5.4 MiB)
Interrupt:10 Base address:0x8000

lo Link encap:Local Loopback
inet addr: Mask:
inet6 addr: ::1/128 Scope:Host
RX packets:9829 errors:0 dropped:0 overruns:0 frame:0
TX packets:9829 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:2679999 (2.5 MiB) TX bytes:2679999 (2.5 MiB)

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.
