You're pinging a host as unprivileged user and /bin/ping was not setuid root?

Also could it be that the address 169.254 is an unroutable address? This is usually the address you see in windows when your box can't resolve an ip from dhcp, so it just gets assigned a random address that starts with 169.254??

Shouldn't that result in a "destination unreach" error instead?

Ipaddress group for lan are:

192.168.x.x
172.16.x.x
10.x.x.x

x can be a number from 0 to 255

Hi guys, the problem is due to iptables. Check your iptables and make sure that is has all the rules to allow you to ping a network.

KIu is right..the problems is caused by iptables. i managed to figure out the at last..but there's another problem occur..i don't know how to save and execute the iptables..
