Ubuntu Networking :: 10.04 - Eth0 Not Up After Pppoeconf
Jun 15, 2010
I recently installed Lucid 10.04 on a P-IV desktop. The install went extremely smooth and Ubuntu was up and running. Hats off to the Ubuntu folks for the excellent user-friendly experience in the installation process. However , I have run into a networking issue. I connected my PC to the router issued by my ISP. This is a plug-n-play type of connection where the username/password settings are stored in the router and there is no configuration required in Ubuntu for accessing the internet. All I need to do is connect the router and my PC using the LAN cable. I was able to surf the net without any issues.
A few days later , this ISP service was down and hence I switched to another wired ISP. This ISP required me to dial a connection using another supplied router. I setup the connection using pppoeconf where I was asked to enter username/password. Again I was able to surf the internet without any issues. Next , I shutdown the system and before booting it , I switch back to my original ISP connection (the plug-n-play one). But now I am not able to connect to the internet. The router lights show that my PC is connected to it , but when I issue ping 192.168.1.1 to check connectivity with the router configuration, I get
Code:
$ ping 192.168.1.1
connect : Network is unreachable.
Also , issuing ifconfig does not show eth0.
NM-applet also does not appear in my notification panel at the top.
How I can go back to using my original plug-n-play ISP connection? I have read some posts about networking issues , but none quite like this one. Please note that all my Internet connections are Wired connections.
Here is my interfaces file
Code:
$ cat /etc/network/interfaces
auto lo
iface lo inet loopback
iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
provider dsl-provider
auto eth0
iface eth0 inet manual

I am a Ubuntu user (10.04 as of now), since I use it, over a year, I have to manually enter the command $ sudo pppoeconf everytime I turn on the computer and want to connect to the internet, the I click enter some times, enter my password of my internet provider, then I click enter some more times to have internet.I have to do this boring work, 3 times a day, just now I am asking you if you know any way of automatizing this?

i have some trouble connecting to the wireless of the dormitery where i live in. so that is what i already did: connecting to the hidden wireless network via nm-applet i typed in my personal user data using "sudo pppoeconf" connecting to the internet using "pon dsl-provider"
so after i did that everything was working out very well and i was able to use the internet without a problem! but after i restarted the computer the nm-applet was gone so i can't connect to the hidden wireless network anymore. if i try to start nm-applet manually the terminal says:
Code:
jonas@jonas-K50AD:~$ nm-applet
An instance of nm-applet is already running.
(nm-applet:1962): WARNING **: <WARN> constructor(): Couldn't initialize the D-Bus manager.
jonas@jonas-K50AD:~$
if i end nm-applet using the system monitor and try to restart it again i get the following output:
Code:
jonas@jonas-K50AD:~$ nm-applet

It's been a while since i've been trying to deal with this problem but it was useless. I've found many related problems to this, most unsolved and those who had solution wouldn't work for me. I have few mates who have the same problem and still didn't find a solution as well. Here's the problem:
Both on my Desktop and Laptop, the network manager won't recognize that there is a cable pluged on the computer so that it would start my connection. The solution to make it work is pretty simple and its everywhere: use pppoeconf.
Altough that does the trick to make my internet work, i get another problem that i found out to be related to this one, which is: I can't use VPN. Which make me assume that one problem is related to the other, is that on my laptop, which has wireless internet, ubuntu will recognize it and then i can simple use vpn. My desktop, on the other hand, isn't that lucky and does not have wireless, so i can't just use vpn. So far, i've been using vpn on windows when needed, but switching systems is really a pain, not to say i'd rather do that on ubuntu.
Few other suggested solutions were to use 'wicd' and other network managers, altough for some people that did work accoding to what i saw on boards, that didn't really work out for me as well. Wicd coldn't recognize it either. Other suggestion was to check on some txt file on ubuntu, erase few information and let it 'fill up' automatic, it didn't work as well(sorry i don't remember all details on this one).
This problem happened on:
First, wubi for ubuntu 9.04
Ubuntu 9.04(normal install.)
Ubuntu 9.10
Happened both on my Desktop and my notebook, but the same version i installed on both of them were used on other computers and they did work on them so i strongly believe it has to do with the os itself.

Why is pppoeconf not creating dsl-provider file in /etc/ppp/peers/ directory.I just re-installed Lucid and now facing above prob. I cannot even copy an dummy file to the above path (even using sudo)It does not give any error,but then file is also not copied. I observed after re-installing,old kernels are also visble and i can login in low graphics mode I expected that after fesh install,there would be only kernel..default one..

After the use of pppoeconf, the network manager does not recognise neither the wired nor the wireless connection anymore. (It nicely did it before that) I tried to replace the etc/network manager folder with that of a different machine. Still the same. What else can I do to reset Network Manager ?

I'm a Linux noob an I am really desperate for some top, top, top assistance. Been battling a while now with my iBurst USB modem driver and hope there is someone out there that can help? I have been through umpteen forums and threads and tried literally everything I read, but to no avail. I also realize there aren't many Ubuntu users that use the iBurst modem, but I am appealing to the few out there that do.
I have installed the open source ibriver-2.6.31 for my iBurst USB modem. Initially all went well with fast connection etc., connection everytime I boot, until... I started updates of 10.04 LTS, that is when I became aware, from the forums, that a re-install of the driver is required after every package update due to no "package management" in the iBdriver. what a pain in the proverbial to say the least!
Anyways.. now I am the stage where the driver is always installed, but...all of a sudden, I need to run pppoeconf and set up the driver after each boot to get connected!!!! If I can't find a solution it will force me back to Windoze7 which I dread to do! Can a script be written to pppoeconf (rp-pppoeconf.iso is loaded I think) automatically during boot perhaps?
So any top Linux hacker or "notsonoobasIam" user out there with a iBurst modem and similar pains & mis-fortunate experience please share your ideas and thoughts to correct this problem permanently for me please? (I should maybe mention that the other day I performed the "Grub2 Profile" exercise to try and speed up the boot time, this does not perhaps have something to do with the fact that I need to reconfigure in pppoeconf after every boot does it? I doubt it)

5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.
I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.
Code: echo !HH | nc 192.168.1.6 80
I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?

I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).

I'm running a dual boot Ubuntu 10.04/Backtrack 4 (Ubuntu 8.10) system. I can get internet in the BT4 side but not in the Lucid side. In Lucid I can ping my router, and the network manager says I'm good to go, but I can't get to any web sites. It all started when I tried to put my laptop on another network by mimicking the settings of a computer I had just unplugged from the network. MAC address and all.
ifconfig eth0:
Code:

I have a hardware device with two ethernet ports, eth0 and eth1 running Centos 5. Basically my goal is to forward packets from eth0->eth1 and eth1->eth0 as well as get a copy of these packets for analysis. If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.

I wonder what is your opinion about the best method for using an ADSL modem. Router or bridge? I did read some articles that say "that the bridge mode gives you more stability and has higher speed". Is that true?
Furthermore, you suggest any alternative to "pppoeconf"? I've been getting this errors ( in the plog), related to "PAD packet loss" and also errors in "PPPOE Discovery", even when I am connected. When this things starts to show up on the log, my connection "pauses" for some seconds. I do not feel very safe with this program.

If I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got

i am using debian lenny stable and gnome desktop environment and having an i386 architecture.I configured to connect to the broadband connection using pppoeconf with the default options and the setup went smooth.when i connect to the internet using the command
jj@debian# pon dsl-provider
plugin RP-pppoe.so loaded
jj@debian#
and when i check that if i am really connected to the internet i used the following commandjj@debian#ifconig
it showed my ip address dns,etc in the ppp0 coloumn .But when i open up my iceweasel browser and also the epiphany browser and when i try to load a web page it states that it couldn't find the server.so guys please tell me how to configure it correctly and please tell me what i did wrong. p.s when i tried to configure the adsl connection by the alternative using the command pppoe-setup it states that It couldn't find the /etc/ppp/pppoe.conf file so do i have to create it on my own?

I have got the following Problem: I installed the 64 bit lxde Debian version... I couldnt configure the network during the installation because I just have a dsl modem and not a router... so the configuration of the network failed.... after the installation I started debian... and was surprised about the lack of "basic system configuration"-software that had been installed... I couldnt find aptitude or whats the debian-Update-Programm called .... instead I found OpenOffice... HAE? then I tried to configure internet access..... so I started a terminal and tried to start pppoeconf... but the program wasnt found! ARRRGG! What am I doing wrong here.... Why are these system utilities like pppoeconf not always installed...

i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through

On my machine (Desktop PC) I have 2 network card : wireless (rt61 802.11) and a wired card (BCM44). When I install debian 5.
The wired card is detected and logical name eth0 is assigned, while wireless is not assigned I install firmeware* software to configure the card. It is done in some way ( I used mnetwork from mepis, it works fine).
Now the problem: eth0 disapears, and no eth0 inteface found? ifconfig gives just wlan0.
Question: Why there is no eth0, it was before configuration of wlan0 ?
How to active again eth0, or ho to create the logical eth0?

I'm about to add pci ethernet card. Currently the mobo nic is eth0. When I add the new card will it by definition be eth1 (or will it become eth0 and the mobo nic become eth1)? The broader question is: how are the "eth's" numbered at boot time? If I were to add a 2nd pci nic, could I predict which would be eth1 and which would be eth2 (based on pci slot number??)? Is there somewhere to readup on this to get a broader understanding?

I've set up Internet connection sharing, with Internet from wlan0 being shared to eth0 locally. Interface eth0 has the IP 192.168.0.1, since it's the gateway. Problem is, every time eth0 is disconnected, it forgets its IP, and then nothing works until I
Code:
ifconfig eth0 192.168.0.1
again.
Is there a way to permanently set the IP for eth0 to 192.168.0.1 so that it's remembered across disconnects?

I have a 10.04 box connected to a router with DHCP and wireless. Lathough it can connect through the wifi, I can't get the connection working with the ethernet cable (which is the one I wanna use by default).
Code:
I may add that it's the default auto connection, but I've also tried to create one manually setting the right ip address, gateway, etc, and attributing the same ip on the router to the MAC address of the card. I've also tried to edit manually the interfaces file, with no effect, or no good one at least. This log comes from a moment when nothing has been changed from the original 10.04 installation.
And I have connected a laptop to this very same cable, and the connection worked straight away...
