You don't have a DEFAULT route in your routing table. Your Linux
computer can ping local machines (on the 192.168.0 network), including
your router, but doesn't know what to do with packets destined for
beyond your local network. You need a route like:
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0
the command:
route add default gw 192.168.0.1 dev eth0
should do it for you, but it belongs in /etc/sysconfig/network as:
GATEWAY=192.168.0.1
GATEWAYDEV=eth0
