network connected no internet

May be your ISP not use DHCP? Does your Windows configure to get IP address automatically or it use static IP?

it was automatic but I took my windows no longer exist. How do I check to see if it is my ISP

What setting you have on computer you now use to write this message?

this is my windows pc a spare pc. This has automatic ip address and everything set up when it came from dell. My linux computer is a totally different computer.

Run in terminal

ifconfig eth0

Copy output here

okay

you run this command with ethernet cable connected?

No I can

Run this command with ethernet cable connected

okay, i see some strange setting like 127.0.0.1
Open Edit connections in Network Manager

There should be connection named "Auto eth0". Choose it and click Edit. Then choose "IPv4 Settings" tab. Is there chosen DHCP method?

Okay
what do u want me to do?

Yes it says Automatic ( DHCP)& Automatic (DHCP Address only) which one

Automatic ( DHCP)
There no other connections expect "Auto eth0"?

*except

Auto eth is the only one I did what is the next step

What NetworkManager says, when you connect cable? Auto eth0 connected?

yes but still not internet

it is saying no network connection it is saying wired connection 1 does this mean I have more than one connection?

Try to copy IP setting from computer with working Internet. Return to editing connetions and choose Manual method. After that enter IP address, Mask and Gateway.

okay

I don't see gateway on this read out of the ip address & mask

Where you don't see gateway? In NetworkManager?

I see it but what is the number for the gateway. I don't see a number is what I mean

Gateway means IP of Gateway. In Windows it should be shown in connection settings near IP and Mask

when I hit apply it said wired network established so I got my network established now how do we get it to get online

try to run ping in terminal to check

ping 8.8.8.8

just type ping in my terminal

I right clicked and my internet information came up which it never did before is that a good sign?

No, it just because you choose Manual mode.
Does ping work?

no when i typed ping in the terminal no command ping found did u mean it gives me a list of other words like bing wing ding etc

Then try to open address 209.85.148.147 in browser

Are you sure you're typing it correctly? For example, on my system:

ek@Apok:~$ ping
Usage: ping [-LRUbdfnqrvVaAD] [-c count] [-i interval] [-w deadline]
            [-p pattern] [-s packetsize] [-t ttl] [-I interface]

rtt min/avg/max/mdev = 553.092/665.180/857.089/117.911 ms

On the other hand, if you type it incorrectly, for example:

ek@Apok:~$ Ping -c 5 8.8.8.8
No command 'Ping' found, did you mean:
 Command 'ping' from package 'inetutils-ping' (universe)
 Command 'ping' from package 'iputils-ping' (main)
 Command 'bing' from package 'bing' (universe)
 Command 'wing' from package 'wing' (universe)
 Command 'ding' from package 'ding' (universe)
 Command 'jing' from package 'jing' (universe)
Ping: command not found

then I am tying it wrong. What do I need to type in on my system to get it to ping? do I need my Ip address name of my computer?

Ping is only one way of checking. Try to open 209.85.148.147 in Firefox

To ping, just run this in a Terminal on the affected machine:

ping -c 5 8.8.8.8

That's like the command Maxim Petrov gave you, but it has the additional advantage that it stops by itself, so you don't have to manually terminate it with Ctrl+C. (@Maxim Petrov: I hope you don't mind.)

Make sure ping is not capitalized, and that there is a space between ping and -c, and a space between -c and 5, and a space between 5 and 8.8.8.8.

Please also attempt to open 209.85.148.147 in a web browser on the affected machine.

it says network is unreachable

Run again
ifconfig eth0

okay what am I looking for when I run this command?

copy result here

Strange. Copy here file /etc/network/interfaces

okay

it says permission denied

If you ran

/etc/network/interfaces

then that attempted to run the file as a program. But it is not a program; it is a configuration file. And you do not want to run it; you want to see what it contains. To make the contents of the file display in the Terminal, you should instead run:

cat /etc/network/interfaces

it says auto lo iface lo inet loopback

is that a good thing or a bad thing

Edit Connection again and choose IPv6 tab. Is there IPv6 disabled?

it says ignore do u want me to disable it?

No, it should be ignored.

okay what is our next step?

Are you sure that you correctly enter IP address and Mask when editing connection?

 do u think my firefox is not installed right or something like that?

yes I am sure I can try it again.

Do u think it is some kind of a driver issue?

Hey does anyone else have any idea's

Question is marked solved. You should reopen it.

I am not sure y it is marked solved I never did. But do u have any idea's thoa?

The 'ifconfig eth0' output in #43
"RX bytes:22369905 (22.3MB) TX Bytes:13902 (13.9 KB)"
shows that there was internet traffic on your machine. So apparently at that time the network connection was working.

So it might be possible that the network is working, but only firefox is not correctly configured.

To check if package management can use the network, please open a terminal (ctrl-alt-t) and issue the commands

ifconfig
sudo apt-get update

You will be asked for your password, please enter it when requested and note, that you will not see any feedback when typing the password (no echo, not even '*' placeholders). When the second command has finished select all output in the terminal window (edit - select all), copy it (edit copy) and paste into a new message of this question thread.

You can change this status's question back from Solved by posting a message at https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/167365 (type it into the big text box near the bottom of the page) and clicking the "I Still Need an Answer" button. As delance has mentioned, you should do this, because right now most people will assume your problem is solved in a single glance.

@Manfred Hampl
Mangus Q Allen has no Internet connection of any kind in the affected Ubuntu system,, and thus cannot access Launchpad while booted into that system. So how do you want him to paste the contents of the Terminal on that machine here?

I still need a answer

@ Manfred Hampl

It is pages of output but it basically says W: Failed to fetch hhp:// security. ubuntu.com/dist maverick-security /multiverse/il8n/Translation-en.bz.2 could not resolve " security. ubuntu.com

would it work if I had internet connected to my unix machine?

Maybe I was mislead by some of the question/answer messages, but in comments #7, #11 and #43 I saw an 'ifconfig eth0' output like "...RX bytes:22369905 (22.3MB) TX Bytes:13902 (13.9 KB)..." This is evidence that there was 22.3 MB data successfully downloaded via the eth0 interface. Still you say that you cannot connect to the internet. From where did that traffiic come?

Can you please give more information about your network setup. Do you have a router? Do you have a small local area network?

Please again provide the output of these commands:

ifconfig eth0
ping -c 5 8.8.8.8
ping -c 5 127.0.0.1

And when giving that output please try to
1. include the line with the command
2. try to use copy/paste: in the terminal 'edit - select all' and 'edit - copy', and then paste it to a document that you can transfer to your computer with internet connections for pasting into the question document (this is to avoid typo errors as there must have been, like "etho" instead of "eth0" etc.)

I have a high speed modem from time warner cable I have no small network it just one system running straight from the high speed modem to the computer threw a ether net cable. I will ping my computer in a few seconds the

ok, it seems to me that the problem is in network configuration on the Ubuntu system.

Do I understand your current ways of working correctly: You have a Windows PC pluuged in at that cable where you want to connect your Ubuntu PC to be able to answer questions on launchpad? If this is a misinterpretation please tell exactly what and how you are currently doing with respect to networks and do not execute what I write below!

If that is the case please open a terminal on your Windows PC and enter the command "ipconfig".
Write down the numbers that you see besides IPv4 address, net mask and gateway.

Then plug out the cable from the Windows PC and plug into the Ubuntu PC.
Issue the command "ifconfig eth0" and note down what you see as numbers near Inet address, bcast and mask.
Then go to NetworkManager, select manual configuration for eth0 and enter the numbers that you have written down from the Windows PC.
Issue the command "ifconfig eth0" again and look if the numbers shown there have changed.
Issue the command "ping -c 5 8.8.8.8" to check if you have a connection.

The final solution should be to switch back the configuration settings in network-manager to automatic, if that is what your ISP needs (and what seems to be what your Windows PC successfully uses).

The ping said network unreachable the numbers did not change on my ubuntu system I typed in the numbers from the windows system it was a no go

did it have to have the " around it cause it wold not come up when I put the " around the ping command

This is weird. I think we have to rule out hardware problems.
Did this PC have a successful network connection once in the past (maybe even with a different operating system).
When this PC is running and plugged in to the network, are there network activity indicators blinking (on the high speed modem and on the network card of the PC)?

Please remove the network cable from that PC and issue the terminal command
ipconfig
and copy/paste the complete output
then connect the PC with the network, wait half a minute and issue the terminal command
ipconfig
again, and again copy/paste the output.

It says no command found.

sorry, my fault, it should be

ifconfig

okay I will run that

Do you see the difference? Now you have got an IP address of 169.254.8.27 (no more the 127.0.0.1).
So please try the ping command again
ping -c 5 8.8.8.8

it says Usage { - KRYbdfnqrvVaAd} [ -c Count] [ -i interval] [ -w deadline] [-p pattern] [ -s packetsize] [-t ttl] [ -I interfaces] [-M pmtudisc-hint] [-m mark] [ -S sndbuf] [ t Tstsmap-options] [ -Q tos] [ hop ...] destintation

is it important when I hooked up my internet to my ubuntu system and clicked on my fire fox it says unable to find proxy server

is it important when I hooked up my internet to my ubuntu system and clicked on my fire fox it says unable to find proxy server

Sorry for the delay in responding, but I was away from home for some days.

when the ping command comes back with 'Usage...' you must have mistyped the command.
As already written above: in all such cases please do not only post the response in this question document, but include the full command that you have issued in your posting!

To continue with your problem:

Please start again:
unplug the network cable from your Ubuntu computer.
Issue the command
ifconfig
This will most probably show an output without "inet addr", just something with "inet6 addr"
The connect you network cable to your Ubuntu computer (and leave it connected without interruption until you have done the things below)
Issue the command
ifconfig
This should now show an output with "inet addr", and figures similar to 169.254.8.27

If that is not the case please post what you have done and what you have received (as exact as possible) in this question document.

If you did receive an inet addr 169.254.... response:
please issue the commands
route
ping -c 5 8.8.8.8
and post the output (again as exact as possible)
