Debian Squeeze: eth0 connects but I don't have internet
Debian Squeeze: eth0 connects but I don't have internet
I know people should use google and the forum search to solve that kind of "easy" questions, but I'd like to say I already spent two hours trying to solve it by my own So sorry if there's already the same exact question somewhere around the internet
Resuming my situation, I installed Debian Squeeze on my system two days ago, using a wired connection to internet (which worked fine). After that, I had to install the non-free wireless package in order to scan wireless networks. It now works fine, and I can connect and get to internet. But with wired connection, i connect via eth0 and none of my applications work. And they're not in offline mode.
Also, i already went here: http://wiki.debian.org/NetworkManager and I checked if that was my case. I tryed what they say several times in some different ways, but I still can't connect. Even more, if I change something like they say, I get "unmanaged device" and I can't even connect to the internet. And the wired connection works, I'm using it right now on my ubuntu 10.10.
If you want more information, I just tried to ping sites like google.com or youtube.com using network preferences and it does work, it gets 100% of the packages back around 50ms later, so the internet appears to work. Also, when I connect via wireless, everything works perfectly.
If you need them, here are the contents of:
/etc/network/interfaces (it was like this after installation):
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
# NetworkManager
iface eth0 inet dhcp
and /etc/NetworkManager/NetworkManager.conf (it was like this after installation)
[main]
plugins=ifupdown,keyfile
no-auto-default=00:a0:d1:ad:18:1a,
[ifupdown]
managed=true
I would be very grateful if anybody could help
Thanks a million!!

Re: Debian Squeeze: eth0 connects but I don't have internet
You could give Wicd a go and remove NM. Wireless and NM didn't play well together initially on my system. With Wicd everything worked. I didn't even had to configure things.

Re: Debian Squeeze: eth0 connects but I don't have internet
In Testing, Network Manager was updated twice during the last ten days, and as of version 0.8.1-4 (1) it no longer needs manual intervention to manage the devices already specified in /etc/network/interfaces. I bet that the online resources has not been updated and they still recommend to change the configuration files manually.
It works as expected with these settings:

Thanks to all of you! I'll try both them when I get home and I'll post a comment later!

Re: Debian Squeeze: eth0 connects but I don't have internet
As it turns out, i did have internet, but I still don't know why some programs can't access the network.
For example, Chromium-browser, skype, the terminal emulator and synaptic have internet, but empathy, iceweasel or epiphany just give connection errors :S
Any ideas about what could be happening? And it didn't just happen to me in one debian installation, i installed another debian testing/sid and without doing anything (just upgrading) exactly the same happens...

Re: Debian Squeeze: eth0 connects but I don't have internet
Install wireshark and see where the traffic is going, and where it's failing when you try using the apps that aren't working correctly. If you can't read the output, save it and attach the file to a post and I'll read it for you.
I ran into some very strange networking behavior when upgrading a couple of my machines from Lenny to Squeeze the other day so I'll be curious to see what the solution is.

Re: Debian Squeeze: eth0 connects but I don't have internet
I really appreciate your help, and I'd like to give it a try, but right now I'm using a wireless connection and I can't test it
But I'll try to connect via ethernet soon, I'll let you know I'll answer as soon as I can!
Thanks!

Wireshark works with both wired and wireless interfaces. Just choose the wireless interface for it to monitor.DanielMarti wrote:I really appreciate your help, and I'd like to give it a try, but right now I'm using a wireless connection and I can't test it

Re: Debian Squeeze: eth0 connects but I don't have internet
I don't know why you get that error. I ran into the same problems upgrading two Lenny machines to Squeeze that had 5 nics between them. It completely fried one nic, a D-link DFE 530tx which used the 3c59x module, which is a very common nic and has been around for years. I really don't know what it was that I did that finally got mine all going. I do know that I had to use dhcp to configure one of the newer 530tx nics that uses the via-rhine module. I could not bring the interface up as long as it was configured with a static IP address. The rest of the nics finally just started working, but that was after I spent a full day working on this trying everything I could think of. I must have configured/reconfigured all those nics 20 times and rebooted the machines a dozen times. (I rebooted machines because I found out that the nic's would come up for a short time after a reboot, then quit working even though ifupdown would they were configured and ifconfig showed them having ip addresses.)mvnetn wrote:I recently switched to Squeeze and have encountered the same connection problem.

The network configuration finally just started working even though I hadn't done anything different, but just kept on doing things over, and over again. Why that worked I have no idea, but it did.
This is a major problem for squeeze. I would have filed a bug report, but I don't have any idea as to what to file the bug against.
Re: Debian Squeeze: eth0 connects but I don't have internet
At the moment I posted this topic I was using squeeze when it was testing, but I changed to Sid untable thinking that it may be solved. But it is not solved, the problem is still the same.llivv wrote:are you running squeeze or sid like you said in your other thread?
