cannot connect to internet
I installed debian 501 yesterday, used a netints and it worked fine. When install finished everything booted up fine but i get no internet.
when i hover over the network monitor it says i have a self-assigned address and i can only get to the debian homepage which i believed is cached i am obviously new to linux and any help would be greatly appreciated |
Can you please post the output from this command (run as root):
Code:
ifconfig -a |
And.....what is your internet connection?---eg DSL, Cable, etc.
Do you have a router? Open a terminal and enter: ping www.google.com If no reply, then try: ping 74.125.155.104 If the second one works, and the first does not, then you have a DNS issue. Depending on your setup, you may get DNS server addresses using DHCP, or you may have to enter them manually. |
I had the same problems with Fedora 10. But now it is solved. May be you would find your solutions in the following link.The link connects you to the solutions that I got from this forum. Hope it helps

nirmalya2006, i tried that link and only possiblilty would be
then you need to add the DNS from your provider in /etc/resolv.conf nameserver xxx.xxx.xxx If you don't know the DNS from your provider, you can use openDNS nameserver 208.67.222.222 nameserver 208.67.220.220 but how do i add to that folder? also there is an existing folder... update-lib.d/avahi-daemon... |
I may be incorrect, but from the looks of the ifconfig file, you may not even have an ip address. The command listed here will tell the network card to go out and get an ip address from the router or DSL modem.
If you have a wired connection, run as root: Code:
dhclient eth0Code:
dhclient wlan0 |
The problem is you didn't get an IP address from the router.
You should check the contents of /etc/network/interfaces If you post the content of /etc/network/interfaces, please put [ code ] and [ / code ] tags around it (leave out the spaces) You can do that by clicking go advanced and using the # button. This is the reference I'm using: http://wiki.debian.org/DebianReference/Network It is very extended, maybe too much for a clueless newbie (not saying you are clueless). It does say your installation should have set up the network connection correctly. It also says what /etc/network/interfaces should contain, somewhere. EDIT: please say so if you can connect to the internet after you run the command joeseph0404 gave you. Put also post the contents of /etc/network/interfaces. Running dhclient every time you reboot isn't much of a solution IMHO |
I second what janhe says. The command I gave you is more of a temporary test to see if dhcp will work, but as janhe said, editing the interfaces file is a more permanent solution.

ok well no good, hes what i got:
