i am also using the opendns servers if that helps

i have no idea were to go from here

hmm the error for the nslookup makes it seem like you do not have dns set up properly. Try doing an nslookup on a working computer for google and then ping that IP address on your Ubuntu 8.04 tower to see if you can ping a regular IP... if that works then you just need to find your DNS server from a working computer and set that on your Tower


ohh yeah also try pinging 192.168.1.1, which is your router.. if that works you know your card is working, and since you have a default gateway and you know your router is working, that should be a pretty good sign it is DNS

[minispalla]

i tried pinging the 208.67.222.222 (opendns's DNS)
but that didnt work, but if i go to firefox and i type http://64.233.167.99/ for the address it goes strait to the google home page but if i try to ping that address it doesnt work ?


any other ideas ?

[vorgusa]

right click the Network Manager icon at the top right of your screen and go to Connection Information and tell me what you see.. Just because you can not ping something does not mean it is not there.. some sites block pings so it just drops.

[minispalla]

oh i didnt know that and it says this

interface:Ethernet (eth0)
speed: 100mb/s
driver: via-velocity

ip address: 192.168.1.101
broadcast address 192.168.1.255
subnet mask 255.255.255.0
default route 192.168.1.1
primary dns 208.67.222.222
secondary dns 208.67.220.220
hardware address 00:50:2C:0A:4C:CF

is it possible there is some kind of firewall
i already uninstalled that ufw a while ago is there anything else like that ?

Although you have an IP address associated with your interface, eth0, you are not actually connected to the router:
--- 192.168.1.1 ping statistics ---
246 packets transmitted, 0 received, 100% packet loss, time 245009msBy the way, if it won't reply in 3-4 pings, it sure won't do so in 246. You can control the number of pings by specifying the count:
ping -c3 192,168.1.1I suggest removing all the data here:
ip address: 192.168.1.101
broadcast address 192.168.1.255
subnet mask 255.255.255.0
default route 192.168.1.1
primary dns 208.67.222.222
secondary dns 208.67.220.220
hardware address 00:50:2C:0A:4C:CF
and specifying DHCP. The problem I have with static IP addresses, when you are troubleshooting, is that when you are not connected, you have an IP address; when you are connected, you have an IP address. With DHCP, you only get an IP address when you connect. When you have everything set to DHCP, then do:
sudo dhclient eth0Let us know if you connect or time out. If you need a static IP address for some other reason, let's address that once we actually connect.

alright this is what i got

and the internet still doesn't work

Try checking the physical parts, such as the cable, lights on the router, and port... Try each of these to see if one gives us new info

1. Look at the port where the cable is plugged in to see if there are lights on both the router and the computer.

2.Move the cable to a different port and test to see if it works.

3. Try a new cable and see if it works.

If all of these work fine try taking the cable from your modem and plug it directly into your computer then restart the modem and wait a couple min then test to see if it works.
