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?

Smile iptables

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.
