Ramesh I find this line a bit suspicious in your routing table. Given that your gateway is in a different subnet, you might need to set the netmask to 255.255.0.0 instead of 255.255.240.0
134.104.16.0 0.0.0.0 255.255.240.0 U 0 0 0 eth0 Also, are you sure that you are running katcp client from the same machine that you are telneting to the roach? And have you set the port of FpgaClient class to 7147?
