can't ping hosts outside local network

arunksit · 02-20-2008, 11:06 AM

I am using ubuntu 7.04 on my laptop.Its connected to a local network.Internet is avaialble on my system thru a proxy server (CCproxy)on a windows machine on our local network. The problem is that i cannnot ping hosts like google.com. pinging IPs on local network works. How can I enable ping..?

Sounds like either you computer doesn't know the gateway through which to send those pings or they're being filtered by the proxy.

Hi arun...

I think you must be using firefox to route through your proxy.....

Okay here is the deal....

Try the following things on your linux box and post here:

Code:

ping 208.67.222.222

if this ping works ... it means your comp does not have dns resolution...

Login as root using

Code:

#su

Code:

root#vi /etc/resolv.conf

Then add/edit the lines

Code:

nameserver 208.67.222.222
nameserver 208.67.220.220

The ip's i have given are that of opendns which works well for me... You can also use primary or secondary dns given by your isp.

Then try pinging google, otherwise post here and i will help
