Unable to ping to domains like google,bing

[luckyoye]

Hi folks,

Recently installed the Vmware image of backtrack 5 R1.I have configured the network settings as per instructions,set the VM N/w setting to bridged,have configured a static IP address in the wcid,have added the ip,netmask and gateway in /etc/network/interfaces.In the resolve.conf i have entered the default gateway address as name server(or should it be the preferred dns server addr- i have tried this too)

Iam able to connect to the internet and browse webpages through Firefox,but not able to ping the IP addresses,i receive no reply.I'm able to ping the local host and the default gateway.The BTVmware image is hosted on windows 7 64bit ed and iam unable to ping from the windows 7 to the Backtrack.

Iam really at my wits end and really need some help.My internet connection is a wired broadband connection,which is connected directly to the NIC.

Thank you and regards,
Lucky.

Is your router dropping outgoing ICMP? Can you ping out when using a different operating system?

@shadowzero
Thanks for the reply,when i ping out to outside domains,i don't receive replies from them.iam able to ping local host and with loss of packet,i can also ping and receive replies from another VMware windows 2003 server and i can ping from the same win 2003 server to the backtrack 5.

Iam able to ping to internet domains from the VMware windows 2003 server,but not from the BT5.

P.S:Please note iam able to access the internet from any internet Browser on the BT5.Its the ICMP that's got me in the fix.

Thank you and regards

Can you ping those hosts on IP?
www.bing.com =
Addresses: 82.94.229.16
82.94.229.8

Google =
74.125.77.99
74.125.77.104
74.125.77.147

Maybe you've got some ip filtering rules setup? What is the output of iptables -L

[gunrunr]

and alot of systems have icmp like ping blocked by default, such as machines running vista and xp. some servers and firewalls block it as well due to the old ping of death attacks.
personally instead of pinging victims i rather just run simple nmap scans, especially with the -PN operator to exclude pinging. -sS works well also and is a tcp syn scan

The IP Table reads like this:

Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

No rules have been set,by default or by me.

Doesn't matter whether i ping their domain name or their IP addresses,i receive no reply for the packets transmitted from my system.I have another guest OS set on the VM,a windows server 2003,iam able to successfully ping to any internet domains from the win2003.

do you have a routing table which contains 'the internet' ?
paste the output of

 netstat -nr
