Connect to internet

[arennuit]

Dear all,

I have a problem using 'aptitude', the ssh shell outputs an error telling me it cannot get to the ubuntu web address to download the package. I believe it is because I did not set the internet connection correctly. So here is my config (I believe it is the most basic one):

I use the ssh shell over the wifi AP provided by my plug computer. I connected the ethernet port to my home router, note that this router correctly sees the plug, provides it with an IP address via DHCP and the other computers connected to the router use the internet with no problem at all.

As this did not work I had a look at my /etc/network/interfaces file and it shows:

# Used by ifup( and ifdown(. See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp


I believe this is the most basic setup, isn't it? You have any idea of where I could go wrong? Or what I could check?

Regards,

Antoine.

Hello and Welcome!

What version of Linux are you using?
And are you able to connect to the Internet at all?
What is the output of

ifconfig -a

Hey Jay,

My linux version is Ubuntu 9.04 (ARM version). I am able to connect to the internet using the other machines on the router but I am not sure how to check my internet access using the plug computer that causes problems, any tip?

As for the result of 'ifconfig -a' it returns:

Does that give you any more idea? Whatever the answer, thanks for this bit of time you take to help!

Is there a firewall? If yes, does it allow multiple interfaces from one machine (IE eth0, and eth1)? Does the other machines have multiple interfaces, as well?

I found out what was going wrong actually.

The internet was working ok, as shown using a ping on google:

[CODE]ping -c 1 google.fr

I am using a computer with an ARM architecture called a DreamPlug which turns out to be using Ubuntu 9.04.

Ubuntu for ARM architecture is no longer maintained (probably for some strategic reason which are not relevant here) and it turns out that the ubuntu servers that are used for the package management (the ones used when runnind commands 'aptitude' and 'apt-get') are not the same for the maintained version and the unmaintained version.

This is all coming out from a site you can find googling for 'bertelsen dreamplug jaunty packages' (sorry this is stupid by the forum engine does not let me post links...).

Thanks for you help guys, you would not have found out without your help!

Antoine.
