static IP configuration problem

[Frank DiPrete]

It looks like the network the machine is on is 192.168.1.0/24 with a
default route 192.168.1.15. www will depend on DNS working properly and
I suspect that your primary dns server would be 192.168.1.15 depending
on what you are using for a router and your setup.

Check the /etc/resolv.conf file
