dns not working for ppp connection

HI,
I have a ARM board running linux.
I am able to up a ppp connection(using Sim)

/etc/ppp/peers # ifconfig ppp0 Link encap:Point-to-Point Protocol inet addr:10.240.54.226 P-t-P:10.64.64.64 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:5 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:55 (55.0 B) TX bytes:58 (58.0 B)

I get /etc/resolv.conf having dns server addresses ,could ping that addresses,but cannot ping name associated with it.

/etc/ppp/peers # cat /etc/resolv.conf nameserver 10.174.165.55 nameserver 10.174.165.56

/etc/ppp/peers # ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8): 56 data bytes 64 bytes from 8.8.8.8: seq=0 ttl=51 time=777.229 ms 64 bytes from 8.8.8.8: seq=1 ttl=51 time=410.514 ms ^C --- 8.8.8.8 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 410.514/593.871/777.229 ms

i cannot

/etc/ppp/peers # ping www.google.com ping: bad address 'www.google.com'

Hi,

Since you can access 8.8.8.8 (google dns), you should put that in /etc/resolv.conf replacing the 2 not-working resolvers

Regards

Are these valid DNS servers? Yes, you can ping them, but what happens if you try to connect on DNS port 53 via telnet or nc?
