Debian Configuration :: Browsers Cannot Go To Internet?
Sep 3, 2011
I've installed debian and configured the network: I do ping to the gateway and it connects, I ping one distant server directly with the IP and it can see it (but not with ping [URL]), but when I try to use internet it says that maybe the url is wrong, but it is not.
And when I try to update (apt-get update) it give me a bunch of errors :
W: Failed to fetch http://ftp.es.debian.org/debian/dists/s ... elease.gpg Could not resolve 'ftp.es.debian.org'
W: Failed to fetch http://ftp.es.debian.org/debian/dists/s ... ion-en.bz2 Could not resolve 'ftp.es.debian.org'
I'm unable to acces the internet trough my browsers in Suse 11.3, my router assigns me a IP and I'm able to use Skype and Transmission but not my browsers; Firefox and Opera. I've been using the network at school today, there we have manually set our own IPs but now I'm back home and back to using DHCP. And yes, i have set the ipv4 back from "manually" to DHCP.
This is really confusing, I'm currently writing from my Arch install on the same computer. This works fine. The ifconfig output in both Suse and Arch is the exact same:
eth0 Link encap:Ethernet HWaddr 00:23:5A:1B:30:AA inet addr:95.34.XX.XX Bcast:95.34.XX.255 Mask:255.255.255.0 inet6 addr: fe80::223:5aff:fe1b:30aa/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I'm running mac osx snow leopard 10.6.2, installed virtualbox, created a partition with it and on that I installed Ubuntu (looking more specifically, I found it is Karmic Koala). For one, is kubuntu ubuntu karmic like mine? Or is that something different? Anyways, Did all that, installed guest permissions and everything, but before that and still, when I load up firefox, I can search some google things, but whenever I go to an actual page or something that seems like it needs just a little more muscle than google searching, it just crashes and disappears. So I basically can't access the internet.
I even tried installing Google Chrome through the terminal by some tutorial on another site. It worked and I got it all installed. It does the exact same thing Firefox does. I can do a couple of searches (sometimes not even that before it crashes) but when I go any further than that, it crashes.
I just installed Ubuntu, and the Wifi works just fine - E.g. downloading updates works like a charm But when I try to access a page in Firefox or Chrome they just keep loading the webpage, but never show me anything For the record, I'm using 10.04 32-bit. Don't know how must more information to give..But from this, does anyone have an idea, on how to fix it?
am not able to get internet working, am using debian testing. Dunno what is the issue. Here's the lowdown on /etc/network/interfaces :-
Code: Select all# This file describes the network interfaces available on your system# and how to activate them. For more information see interfaces (8)
#The loopback network interface auto lo iface lo inet loopback
auto eth0 allow-hotplug eth0 iface eth0 inet dhcp
I tried all the usual :- Code: Select all$ sudo dhclient (this usually worked/works) $ sudo ethtool eth0 $ sudo systemctl restart networking
I have been using another OS but thought for Ham Radio Debian might be good however my stupidity took over right at the start.Have a live cd and works fine but I don't know how to connect to the Internet.Using DSL.
I need to shear internet i use isc-dhcp-serve and it work but internet doesn't work i have triad so many commends but still networking ... My setting is eth0 - wan eth1 -local
After doing updates to get current with Debian Jessie, I've noticed very annoying network problems going on.
This all happened while also setting up a media server box which led me to much confusion, much of what is described here [URL] ....
I've started this new thread to try to diagnose and properly take care of this specific problem alone:
Browsing the internet becomes very slow, unbearably to the point everything keeps loading up forever. This only happen while having a torrent application opened, the effects are almost immediate, closing the application and browsing resumes as normal.
How about throttling back torrent? This does not work, it even doesn't even need be at top speed. With bare minimum connections and speed will still lead browsing to a crawl.
Even so, every other device on the network is un-affected, router and other PCs continue to browse and respond very well, making it a specific on the computer in question (but also happens on my other debian jessie machine).
Can I even reach the internet? Yes I can, and this is the weird part... I can ping, solve DNS and almost everything else without issues, the only thing affected is actually browsing the internet.
I'd even setup DNS cache with dnsmasq to see if it could speed things up. Disabled ipv6, and trying pretty much every method I could find.
Having pretty much ruled out dns problems and internet connectivity, I'm at a loss for what to look for and try. Only symptom I can describe now is that the browser will start to load up webpage but never completes... but only while torrent is active.
My current setup:
I'm on Debian Jessie, a desktop with eth manually connected. Using dnsmasq for dns caching. Disable ipv6 on the network (by the way, it keeps disabling it self I dunno why).
Running KDE with ktorrent as the client. The same thing happens on my setup media box, also Debian but with deluged running instead.
Browser in question are Firefox and Chrome, both have issues with this.
Turns out it was just a setting in my own router, that apparently limits numbers of connections made, meaning while torrent is working other connections were sure dead.
But it also happens when lots of connections are being made in other ways too. The router in question is Humax HG100R-L2, provided by my ISP. The setting is in the firewall section called IP flood detection.
I rebooted my vServer (Debian 8) and it doesn't came back up. Well, I used the rescue console on my server and the server seems to be running fine, except the network was broken. So I tried 'ifconfig' but nothing came up. So I tried to enable my interface with 'ifconfig venet0 up', and now it appears in my ifconfig list
Code: Select allroot@i67svof:/var/www# ifconfig venet0Â Â Link encap:UNSPECÂ HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00Â Â Â Â Â Â UP BROADCAST POINTOPOINT RUNNING NOARPÂ MTU:1500Â Metric:1 Â Â Â Â Â RX packets:557 errors:0 dropped:0 overruns:0 frame:0 Â Â Â Â Â TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 Â Â Â Â Â collisions:0 txqueuelen:0 Â Â Â Â Â RX bytes:36463 (35.6 KiB)Â TX bytes:0 (0.0 B)
My HWaddr doesn't look that well :) 'ip addr' prints this result:

These are the last lines in /var/log/syslog:

And finally my network config in /etc/network/interfaces
Code: Select all# Auto generated lo interface auto lo iface lo inet loopback # Auto generated venet0 interface auto venet0
I'm a new Debian user but I've been around Linux for awhile. I wanted to try Debian because I wanted something stable and that I could set up myself from a minimal install. However, I'm having issues with my WiFi connection. I'm running KDE and connected to the network, but I can't access any webpages or ping, for example, google.com. I know the network is working because I'm connected to it on my phone and my wife's Macbook. Here's the output of lspci:

I'm using jessie. So far I've tried using firmware-iwlwifi from backports and installing kernel 4.3.0 from the stable repos.
I set up a vpnc connection, and it says it connects fine, but then I have no internet connection at all, and cannot ssh into the remote server(the reason i need this vpn) or do anything else involving the internet.I question if it actually connects at all, as sudo vpnc myconf.conf only shows the connect banner and never progresses from there.
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: URL,,, 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 ......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.
I've been using Debian for about 6-7 months now. I've had a bit of a major networking problem for the past 4 months or so that I've been trying to fix - specifically, it started when I upgraded to Jessie. I can connect to wifi just fine, and sometimes I can even use the internet for brief periods of time (exceedingly rarely). Then... nothing. No network access, period. I can't ping any outside servers, I can't ping other computers on my network, and I can't even ping my router. Pages I try to load just stay "connecting" for all eternity, network printing fails, and so on.
So after four months of searching online (I've read through way more wireless documentation than I care to say), I finally gave up and admitted that maybe I screwed something up during upgrade to Jessie (as a matter of fact, I did, I had to do the upgrade in two increments [somehow] because my root partition was too tiny by mistake) and I did a clean install. Since I had /home on a separate partition, I was able to keep all my user files, but all settings regarding networking were wiped. So after installing firmware-iwlwifi so I can use my wireless card, I tried connecting to wireless! Success! Then I tried connecting to the internet... success! Briefly. The next morning I tried using the internet again, and it failed in exactly the same pattern as before.
I don't know much about what's going on here, but here's what I do have available:
I do have to use firmware-iwlwifi, which I installed by doing apt-get install firmware-iwlwifi. I don't think it's an issue with the wireless card itself (hardware-wise), the laptop dual-boots Windows 7 (that I never use anymore), and Windows 7 is able to connect to the internet just fine. Connecting directly to my router by ethernet cable works fine, I have perfect internet/network access then.
I can confirm that my laptop is receiving an IP address and that it is using ARP correctly to get the MAC address of my router (I confirmed this by doing the arp command, it has the MAC address correct, I checked from another computer with my router's config page) All other computers on my network work perfectly with my router. To confirm the router/its configuration isn't at fault, I did a full factory reset of the router, but to no avail.
Out of curiosity I tried installing Wireshark (using an ethernet cable to download it) to monitor what happens when I try to access a webpage. I'm no expert on networking, but I noticed something out place when I compare a capture from the affected computer to a capture from one operating normally - there are a lot of STP packets showing up. I did some checking around, it looks like STP is involved in bridging and more complex networking setups (involving switches, for example)... but it shouldn't be found on a home network, especially where there's no bridging whatsoever. These STP packets don't show up on packet captures done from any other computer. I've attached a packet capture from the affected computer here, since the forums won't let me attach a .pcapng file.
Here's the output from a few commands I ran during past troubleshooting sessions:
Code: Select allsudo ifconfig eth0   Link encap:Ethernet HWaddr e0:db:55:b5:fe:06      UP BROADCAST MULTICAST MTU:1500 Metric:1      RX packets:12455 errors:0 dropped:0 overruns:0 frame:0      TX packets:7781 errors:0 dropped:0 overruns:0 carrier:0      collisions:0 txqueuelen:1000
I was just doing the normal stuff, working with my raid-setup. Then I needed to reboot. I did that, and then my internet sharing just stopped working?I remember I just did aapt-get update && apt-get upgrade && apt-get dist-upgrade && apt-get autoremove && apt-get cleanbefore booting, and I just dont rembember if that said anyting crucial, but I really dont think so. Anyways, my LAN i working, all my LAN computers speak with each others, and I have internet (...) on the server. But my sharing just doesnt work. This is how I share my internet:
I am currently trying to connect to internet through my wireless card, after half day's effort I reached to this point:
/******The following error appears in the dmesg kernel ring buffer output: ipw2200: ipw2200-bss.fw load failed: Reason -2 ipw2200: Unable to load firmware: -2 ipw2200: failed to register network device ipw2200: probe of 0000:02:03.0 failed with error -5*********/
I found a solution from Intel website saying that the problem might be: "firmware in wrong location or wrong firmware version". So I proceeded to download the firmware and placed it in /lib/firmware. Also I tried to use menuconfig to enable loading firmware via hot-plug, but I think I have done something wrong when I was configuring the hotplug and firmware.
I just reinstalled debian on my computer, I've had it working for a long time, only difference is I used to have Cable Internet and now I use DSL. Anywho, I reinstalled debian from the kde CD on the debian website, it auto-configured my network out of the box. My network is connected to the computer, pinging google works perfectly, and ifconfig shows that eth0 is working correctly without any errors. However on both Konqueror and Iceweasel, every time I try to connect to a website, it tells me the server cannot be found. Basically it acts like I don't have internet. Using the terminal works though, I have installed KDE-FULL from the terminal and wicd, so I know I do have internet. I don't know what it could be, like I said, I installed from the cd and this happened. Maybe there's a bug on the KDE debian cd
I am using Empathy IM client to access to gadu gadu and to message with my friends. The strange thing that is happening is that I keep on being connected and then disconnected and then connected again even if I am continuously connected to my internet connection (no problem when surfing or using skype for example)It also seems to come only from me because when my girlfriend is using the same gadu gadu on her windows laptop simultaneously, she doesn´t get disconnected (whether when she is at home and using the same connection as I am or when she is outside, meaning that it doesn´t seem to come from the whole gadu gadu network)maybe it has something to do with the ports that gadu gadu is using but it is strange that sometimes it is working for a period of time and then not and then again.
I just installed, and evolution doesn't seem to think it has internet. The icon with the power cord in the bottom left is unplugged, and send/receive is greyed out. Internet is working , but it is not using network manager, since network manager says no internet is connected. Maybe this has something to do with it?
I have just installed Debian Squeeze on my spare computer (dual booted with Ubuntu 11.04) and I cannot connect to the internet using Squeeze. Due to my ISP, I have to manually connect this computer and on Ubuntu copying and pasting a text file such as this into the terminal works with no problems.What do I need to do to manually configure my Squeeze internet connection?
I replaced my motherboard and processor but am keeping my old hard drive without reformatting it. Things work well except that I cannot connect to the internet. I am thinking that I just need to reconfigure the connection to see the new network hardware. I tried /etc/init.d/networking restart but that doesn't do anything. What am I missing? By the way it is a wired connection - not wireless.
I just freshly installed Jessie on my Dell Inspiron 5110, I configured the network on the installer and had no problem. I can browse the web, get updates and install software.
But I can't find new networks. It just show "No Networks".

We use an Apple TimeCapsule as a router and backup device for an iMac in my home. I myself work on two Debian installed computers, one with a D-Link DWA-547 (with ath9k wireless chipset) and one with an rt61 wireless chipset.Now, everything goes very smoothly, until the iMac is being used severely online. In those cases, unpredictable, the Debian computers both lose their internet, even though the network-manager still shows a full connection.There are two things I can do in these cases: either reconnect using the network-manager applet, or restart the TimeCapsule from the iMac. Both routines have full success.

Today, I have an ADSL box which is my gateway to internet (192.168.0.1).
I have a Raspberry pi (RPI) which I use as a dhcp & dns server (192.168.0.2).
Recently my mobile phone operator installed a 4G antenna beside my home, and the bandwidth and latency are much better with my mobile phone than with my internet provider (ADSL).
I would like to install a wifi dongle on my RPI (I would get wlan0 & eth0 interfaces)
When RPI detect my shared phone connection (tethering) I would like RPI to automatically route internet:
- from authorized devices on my network to my mobile connexion (wlan0 -> mobile phone). - from other devices to the standard ADSL internet (eth0 -> ADSL box).
I don't want any device to use the shared 4G connexion, best would be authorized devices to be selected by MAC address. How I should properly setup such a network ?
