can't connect Cox internet with Ubuntu 9.04


To any and all:
I am a complete novice at this so bare with me. I just installed Ubuntu 9.04 desktop version. Cox is my ISP currently I am unable to use the internet with it. I have an etho connection with a Motorola SB15101. I can get to Cox's setup menu however once I hit the submit button it states that my system is not supported by them. I called their tech support they told me to call Linux. Any [B]detailed input would be great.

Hi,

Welcome to LQ!

I don't use 'COX' or the *buntus. But I think COX would use the '192.168.1.1' as the modems IP.

I would setup a static IP first, do as root from cli;

Code:
~#ifconfig -a                      #get recognized devices
~#ifconfig eth0 192.168.1.10       #set to a available IP
~#route add default gw 192.168.1.1 #set to your gateway
~#route -n                         #show the route table
~#ifconfig eth0 up                 #should be up already
~#ping 192.168.1.1                 #ping your gateway
~#ping 208.69.32.130               #google.com IP
~#ping google.com                  #test DNS, if fail then
                                   #check /etc/resolv.conf
You should have your '/etc/resolv.conf' setup with your 'ISP DNS' nameservers. I use a third level provider as a backup for my DNS.

Code:
 sample '/etc/resolv.conf';

search 192.168.1.1     

nameserver xxx.xxx.xxx.xxx   #ISP DSN 'replace xxx.xxx.xxx.xxx
                             #with IP from your ISP
nameserver 4.2.2.1           #Verizon third level DNS
nameserver 4.2.2.2   
nameserver 4.2.2.3
nameserver 4.2.2.4
If this works with the static then you are on the way if you want dhcp. You could do a search here on LQ as I know this has been covered before.

Log all data or changes for reference in a written form. I keep system logs for all the machines that I work with. This will get you out of trouble if used.

You should have the documentation for the modem. If you communicate with the COX tech then ask for the 'ISP DNS', modem local IP and see if they allow you to nail your IP for the modem. This information would be needed for any communication with the ISP.

BTW, don't forget about your mail setups, get that info from the tech. It doesn't matter which OS you are using. It will be transparent once you have everything setup properly.

One buck,
When I meant novice I meant I am really green at this. What you replied with looks Greek to me. Think of me as one year old child and walk me through this step by step if you don't mind, thanks

Hi,

Everything that was suggest in the previous post should be performed by root not a normal user. You would either open a console or login as root to the console. You would then enter the commands in the first example from the 'cli' command line.

As for the '/etc/resolv.conf' file you would need to use a text editor to enter your nameserver information. I choose 'vi' but others may use 'nano'. That is a personal choice. If you enter 'vi /etc/resolv.conf' then at the window you would get into the 'insert mode' by pressing 'i'. Once your in this mode you can then continue to enter the information I presented. Once complete you would press the 'esc' key then enter ':w<enter>' to write the file. To quit you would enter 'esc' then :q<enter>.
These commands could be entered together but I felt you should see the difference with the command mode. I suggest that you look at 'vi Commands'. It may not be the easiest editor to use, but it is a standard that is widely used and very powerful.

Once this is complete you should be able to function with the 'inet'. Test it by 'ping google.com', if that's OK then your good to go. If you get errors or 'unknown host' then you have a 'DNS' problem. If 'host unreachable' then you have other issues. Do a 'ifconfig -a' and to get the kernel route table you can issue a 'route -n' from the cli. Post that information if you are getting errors.

I know this has been covered here on LQ. Do a search to get '*buntu' specific aid. What I have provided should get you on as long as your network device(s) are recognized and have the proper drivers loaded. If not then you will need to see what device you are using.

You can see if the kernel has recognized the device via 'dmesg' by doing a 'dmesg | grep -i eth' from the cli. Note that the vertical line between the commands is the 'pipe' '|' which should be a shifted '\' on your keyboard.

Another means to see your device would be to look at 'lspci -vv' to see if your device is there. You could pipe to 'grep' if so desired. Remember there is the 'man command', so if I need information on the 'ifconfig' I would 'man ifconfig' from the cli. Please remember that 'man command' is your friend.

Google/Linux is a wonderful resource.
Plus the search engine here on LQ.

There are several good online references available to you;

'Rute Tutorial & Exposition', 'Linux Newbie Admin Guide' and 'Linux Command Guide' are just a few.

You should be aware of the 'Linux Documentation Project' which is a great documentation source.

These links and others can be found at 'Slackware-Links' . More than just SlackwareŽ links!

Welcome to LinuxQuestions. It is difficult to tell if it is a hardware or setup problem with the information provided.

I use Cox Cable and I'm not sure what you mean by the Cox setup menu. You do not need to use the CD that is provided by Cox and since it is a windows utility it will not work with linux anyway.

No mention if this is an existing or new service. Are you using a router or is your computer connected directly to the modem? Is this the only computer connected to your network? Cox provides one IP address for the basic home service so if you are using multiple computers I suggest getting a router.

Cox provides a public IP address via DHCP. Assuming that your desktop is automatically configured for DHCP we need to know the above answers prior to providing addition help.

On the off chance that is some type of hardware problem any information on the type of computer you have and if it is a duel boot PC etc.
