Hi, Thanks clay and adam for suggestions. My machine can ping the nameserver. I also tried other nameserver Adam suggested still no luck. I don't haven't firewall on my linux machine yet. I'm using Cisco 675 to connect to internet. I don't think my router is blocking port 53, but I'm not sure how to confirm this. Here's the output : ------------------------------------------------------ [mandar at omega /etc]$ cat resolv.conf nameserver 204.147.80.1 nameserver 204.147.80.5 [mandar at omega /etc]$ nslookup - 204.147.80.1 *** Can't find server name for address 204.147.80.1: No response from server *** Default servers are not available [mandar at omega /etc]$ man nslookup [mandar at omega /etc]$ ping 204.147.80.1 PING 204.147.80.1 (204.147.80.1): 56 data bytes 64 bytes from 204.147.80.1: icmp_seq=0 ttl=251 time=36.3 ms 64 bytes from 204.147.80.1: icmp_seq=1 ttl=251 time=29.9 ms 64 bytes from 204.147.80.1: icmp_seq=2 ttl=251 time=30.3 ms --- 204.147.80.1 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 29.9/32.1/36.3 ms [mandar at omega /etc]$ nslookup - 128.101.101.101 *** Can't find server name for address 128.101.101.101: No response from server *** Default servers are not available [mandar at omega /etc]$ nslookup - 209.98.98.98 *** Can't find server name for address 209.98.98.98: No response from server *** Default servers are not available [mandar at omega /etc]$ ------------------------------------------------------ BTW, if it helps, the names of my pri/sec DNS servers are 204.147.80.1 ns3.mn.uswest.net 204.147.80.5 ns1.mn.uswest.net -Mandar __________________________________________________ Do You Yahoo!?
