Applications :: Using 2 PPPOE Accounts Same ISP Connect Through Same Interface Eth0
Nov 6, 2010
I'm using CENTOS 5.5 and I want to connect to internet using 2 pppoe accounts same ISP and i have a sigle NIC eth0.I used adsl-setup to create pppoe connections, 1 is ppp0 and second is ppp1. When i use /sbin/ifup ppp0 it works, i can use the internet, but when i try to use /sbin/ifup ppp1 while ppp0 is connected, nothing happens, i did ifconfig and there is only ppp0 showing.I'm a BIG NEWBIE of linux, i need to know step by step how to make this work, i heard something about a virtual network... but nothing clear.

i'm using opensuse 11.3 and can't connect to the internet, my eth0 interface (which would be my modem i suppose) is found and when i "activate" it with ifup eth0, it gets stuck waiting for data (says so in ifstatus). If i try with knetworkmanager it is also stuck and doesn't connect to eth0. If i try to make it connect at boot, it doesn't work either.
I think the problem might be that in windows xp my modem has a "limited connection" but i can connect with my pppoe password anyway, but opensuse won't let me connect until it finds eth0 is working correctly which it never will because of how the internet company configures the modems i think. I don't know with which command i could "force" the pppoe connection even without a good connection to the modem, maybe that would work. But on the other hand, with other distros i can connect just fine so i don't know really.

I'm having trouble getting my Ubuntu 10.04 machine (Sony Vaio VGN-SR490) to connect to the Internet by way of an Ethernet cable connected directly to my router.
I'm able to connect to the Internet using this same cable using a Windows machine, so there's something wrong with the way Linux is configured.
How do I got about figuring out what the problem is and solving it?
Here are my network settings on Linux:
$ ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
[Code].....
It looks like the network adapters list is empty. I will now install both Windows XP and Ubuntu Linux dual-boot. I'm still not able to access the internet, even through Windows. I'm wonder if this could be a hardware problem with the computer or a problem with the router itself. Other computers can connect to this same router, and work fine. (That's how I'm posting this after all!)

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
Quote:
Ignoring unknown interface eth0=eth0.
ifconfig tells me
Quote:
eth0 Link encap:Ethernet HWaddr 00:25:64:e8:18:2c
inet addr:192.168.0.112 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::225:64ff:fee8:182c/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[code]....
so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?

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:
eth0 Link encap:Ethernet HWaddr 00:1f:16:ba:4c:8c
inet addr:10.136.9.147 Bcast:10.136.9.159 Mask:255.255.255.240

I found multiple sites explaining how to add IPs to a network interface as virtual interface like eth0:0. However I can add IPs to an interface as well using the ip command: ip a a 192.168.2.2/24 dev eth0 What I want to know is how I can make this persistent on rhel/centos.

Yesterday I bought a netbook and a wifi router (TP-Link), I connected the ADSL modem to the router, then the router (output) to the ehternet in the desktop with U 9.10. I configured the router to dial the modem.
The router dials the modem, the modem connects, and I have wifi at home, the netbook (still with W7) connects to the wifi network. So far so good.
BUT now the Ubuntu in the desktop doesn't connect. No netwok. If I run sudo pppoeconf, after a scanning process it says that probably there's another pppoe proccess that is controlling the modem. I guess it tries to dial.
Later, when I install U 10.10 in the notebook I'll have to struggle with the wifi network..

The following are the output of command "ifconfig -a":
[Code]....
The interface "eth0", which is down, was not displayed, but loopback interface has been displayed. So, how can I make my application display all interfaces, including the interfaces which are down, but excluding the loopback interface?

I booted an OS from a live CD. The OS boots successfully but eth0 fails to start. I checked lspci, it outputs these Ethernet card details:
(Broadcom Netextreme II BCM5716 GBabyte ethernet)
ifconfig -a returns only the loopback interfaces lo and sit0. The output of dmesg | grep -I 'eth' is:
"Netfront : initializing network ethernet driver"
When I run service network restart I get:
"Obtaining IP for lo [FAILED]
WARNING: Deprecated config gile /etc/modprobe.conf , all config files belong into /etc/modprobe.d/
Device eth0 does not seem to be present, delaying initialization [FAILED]"
The output of MII-tool -v is:
No MII interface found.
I was also able to find the kernel module bnx2.ko. I did insmod and lsmod lists it.

I have already tried reloading the drivers, restarting the interface (which is missing) and every other solution I found on this forum (well... not exactly all of them but many of them) uname -a gives Linux hostname 2.6.35-27-generic #48-Ubuntu SMP Tue Feb 22 20:25:46 UTC 2011 x86_64 GNU/Linux

I have trouble connecting to internet when connecting using pppoe-start, even though it says it's connected and the pppoe interface is there. I test the connection by sending a ping to a known IP address and got "destination unreachable".

I have two network interfaces on my computer but only one of them is connected to an Ethernet cable. Until now on every Fedora release, the activated primary interface has been named as eth0 and everything has always worked well without any problem. Recently I switched to Fedora Core 12 and surprisingly I observed that for the first time, my primary interface has been considered by the system to be eth1 instead of eth0. I tried to replace the content of ifcfg-eth0 by ifcfg-eth1, yet system gave me an error that there was MAC address mismatching. I conserved their MAC addresses in their files and just replaced other connection parameters ( such as IP ADDR, NETWORK, NETMASK, etc.) but it did't work. When I do "server network restart", the command blocks.
As I try to install oracle on this system, regarding the fact that oracle requires static network configuration on the primary network interface, I don't know how to proceed in order to set eth0 as my primary interface (or rather set the current eth1 to eth0 because it is actually eth1 that refers to my activated primary network card).Just one more time, I would like to remark, that with previous versions of the Fedora Core, on the same computer (with the very same two network cards) I never had problem and I had installed oracle on the system with success, having the statically configured eth0 correctly detected by the system.

I am in need of finding out the physical interface corresponds to eth0,eth1,eth2., As similar like the lscfg command which is available in the AIX operating system. The output given below got it from AIX OS.
$ lscfg -l ent*
ent2 U787B.001.DNWFFC6-P1-T9 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent3 U787B.001.DNWFFC6-P1-T10 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent0 U787B.001.DNWFFC6-P1-C4-T1 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent1 U787B.001.DNWFFC6-P1-C4-T2 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
Is there any utility/commands available to find out the physical interface ?

I have been dist hunting ever since I bought my new desktop in Sept 08. some live cd or even install cd work or don't-- but I have learned some workarounds i.e. pci=nomsi at boot for example. Problem I have now is I have wired DSL (modem only) and need to manually connect. I can install tkpppoe running ./go-gui command but everytime I do I can send out packets but not ever recieving (correct me if I have this backwards). in other words activity is showing upload but not on downloads and can't ping either ip or domain or browse. been trying to find out what's going on I think it may have to do with the eth0 should not pull up an IP at boot which seems to be 192.147.x.x or like that according to ifconfig -a Otherwords, when I covert my modem to a router every is fine but manually connecting with PPPoE software that's another story. I would go with the router mode but the Westell model I currently have sucks with it's firewall. I usually go with a software based firewall. call me old skool lol. Need some advice.. I miss my journey with linux Even though I have Vista Premium solid as a rock--- I miss the special customizations only nix can provide and better security.

I used the network manager to configure my eth0 interface.It is working fine. I have found the nameserver entries in /etc/resolv.conf files. But the /etc/network/interfaces file does not carry the ip, netmask, gateway,network and broadcast entries. It only has a entry for the lo interface. where are the settings for eth0 as done by the network manager, stored in case of ubuntu?

I have 2 network cards eth0 and eth1, for eth0 i set a manual MACADDR in network scripts. Ok so every time i boot, if the cable is plugged in, my eth0 fails to mount or i don't know.. i get this after bood when i type ifoncifg eth0 (eth0: error fetching interface information:Device not found). So i have to unplug the cable when i boot, then plug it in and do a service network restart.

I'm running Debian Squeeze x64 and have an odd problem with both Empathy and Pidgin. After I launch the program and add my accounts everything works fine. When I shut down either program and restart the accounts will not connect. I have to delete the accounts and re-add them and all is good until the next time. It's not a firewall issue as I've tried it with the firewall turned off.

I have a set of PDFs I'd like to index and made searchable. Most importantly, I'd like a web interface so I can search and access remotely. This morning I researched into several different options, but all seemed to fail.
Google Desktop Search - No good because web interface is only to the local host
Beagle - No good because it is no longer support and there are executation errors when running in Maverick
Recoll - No web interface
Strigi - No web interface(?)
I recall using one about 2 years ago that was deployed on Apache Tomcat, but I can't remember the name.

Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?

I have 2 LAN ports. one from the motherboard (on board) and the other from a lan card i bought a few days back. one is use for browsing the net, the other for a media player. problem is i cant connect to both the eth0 and eth1 at the same time. i have to disconnect one of them to connect to the other. and this really gets irritating as it doesnt always work as flawlessly as it should. what am i doing wrong?
