Fedora Networking :: Connection Eth0 Never Active On Boot
Jul 16, 2011
I am trying to sort out some issues following an upgrade from F12.
I have eth0 as the connection I want to use. Prior to the upgrade, this connection was enabled and active at boot.
Now, for some reason after the upgrade it has to be manually enabled at every boot - even though when I go the Network tool, Ethernet Device > General tab - "Activate device when computer starts" is checked.
At every boot time it is inactive.
In all the ifcft-eth0 files, the ONBOOT parameter is set to "yes".
I have a question regarding the configuration of Network Connection. My wired connection is fine right now and when I check the network connection applet, it display active information of eth0. However, when I click the Configure button, the Network Connection window appears but there's nothing in the Wired panel. Should there be a eth0 in that panel? I remember I had one before, but after I messed with some configuration of VPN, my network became unstable and I remove the Network Manager to try to solve the problem. Since then, there's nothing in my Network Connection window, though I can still connect to my router with eth0. Now even after I reinstalled the Network Manager, I still don't get anything.
First time I installed Fedora 12 and I am new to Linux OS completely. The LAN (ethernet) is coming by default and it's status is inactive. When I click on icon, it tries to connect and then shows status still as inactive. Where as my internet works in Win XP. What do I do for making it active. Second, when I try to install xDSL package for my BSNL broadband, the package is not available. Where do I get this package?
Most of the time when I go back to my computer, eth0 has disconnected if left overnight or several hours, and takes around 30 secs to reconnect to my router, finding it a little annoying as the reason I leave the computer on is for quick access to the internet.My computer is connected to the router via an ethernet cable.Used Mandriva and Windows XP on this same hardware for awhile and never came across this.How do I keep the connection to the router active?
i was using ubuntu 9.10 till recently when i decided to upgrade to ubuntu lucid 10.04. turns out the internet icon shows connected after fresh installation but when i try to use firefox , after an long wait it shows server not found. i did a research of my own and found that i am not able to ping even my router.using sudo dhclient eth0 doesn't recieve offers , but surprisingly when i tried dhclient eth0 in root shell with networking internet got configured very quickly and i can ping the router and any website.i forgot to mention i have a wired connection which i am trying to connect and the net is working fine with windows 7 on the same PC.
My machine has Ubuntu 10.4, installed a week ago. I'm connecting to the Internet with a Wireless 3G modem, the interface is named ppp0. Additionally, I have a network card that is connected to a home router, that's eth0. Everything works fine with eth0 disabled, all my apps can access the internet correctly. But, my issue is that when i enable eth0, i can't access the internet with any app.
So why do i need eth0 anyway? The thing is that i must share my internet connection with my sister, who is also connected to our home router. I planned to give her access by installing squid on this machine and configuring her browser to connect to squid. However, since none of my apps can connect to the internet while eth0 is active (whereas squid and all other apps work fine with eth0 disabled) I can't let her connect to squid while squid is working correctly.BTW selecting "use this connection only for resources on its network" under "routes..." of the ipv4 tab of "Auto Ethernet" made it a little better. Firefox and Xchat started to work with eth0 active. Squid still doesn't work though (althought it works just fine with eth0 disabled)
I am running the latest ubuntu and I am having trouble getting networking sorted. I have 2 networks, one wired (eth0) and one wireless (wlan0). I connect to the internet using wireless. The problem is that I can only successfully connect to the internet if I disconnect from eth0. I have hit this problem with Windows machines and the solution was to adjust the "interface metric" in "Advanced TCP/IP Settings" so that the wireless was the preferred connection. How can I achieve something similar in Ubuntu?
Yesterday I did an upgrade and today my box is unable to connect to the internet.
I have tried another cable, it didn't help.
Basically NetworkManager does not connect eth0 to the network, if I try to run ifup from the command line I get:
I can see in network configuration settings, that the device has been correctly detected and eth0 interface is correctly activated, yet when I try to uncheck the box manage by NetworkManager and start it manually, it tells me that the cable is disconnected... I've tried two different cables, different ports on my router - no help.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
Most of my experience configuring network settings has been through various GUI tools available in GNOME and KDE. I have some older hardware that will not run KDE or GNOME and I am trying to configure the NIC. I have installed Webmin to try to configure the interface, and it does fine for setting a static address or DHCP address, but the interface (eth0) is not active at boot.
As soon as I run ifup eth0, it will use the assigned IP or pull DHCP based on settings, but I can't seem to get it to automatically activate at boot. And yes, /etc/sysconfig/network-scripts/ifcfg-eth0 does have ONBOOT=yes set. I need two things...
1 - are there any good cli tools, ncurses or such like netcfg I can install to manage the interface (I have tried the network manager cli tools, maybe I just don't get it, but that isn't working so good for me)
I'm using Fedora 12 on a box with 2 separate NICs in different subnets. The problem is that after a reboot, both NICs always show up as eth0 when you left click on the networking icon on the top right. I have to manually change one of them to eth1 & then things start working.
I just finished installing Fedora 12 on a rack mount server. I was modifying the /etc/sysconfig/network-scripts/ifcfg-eth0 file to use a static IP address, but now nothing works. The device does not boot on start up or anything.Currently, ifcfg-eth0 looks like:
DEVICE=eth0 ONBOOT=yes BOOTPROTO=none[code].....
The eth0 device does not start on boot; the server does not get the IP address, is not reachable over the network, and will not connect to the internet....
I'm using NetworkManager for networking.After a big Debian upgrade I had a new problem.Every boot it create a new (invalid) "eth0" connection, and NetworkManager connect automatically to it.As expected, the connection is invalid, and I'm not connection to the Internet.
What I do to fix this every boot is manually remove this wrong "eth0" connection and NetworkManager automatically connect to my good eth0 connection.
Note: If I boot my machine N times without deleting connections, I see N same and invalid "eth0" connections.I think this happen because /etc / network / interfaces conflicts with NetworkManager, but I don't know what trigger this. Here is my relevant configuration: /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(5). # The loopback network interface auto lo iface lo inet loopback
* No "/etc/NetworkManager/system-connections/eth0" connection is created in configuration, but it's displayed.
I have successfully connected (and authenticated the user) from linux (Ubuntu) to Active Directory (windows 2003) using "Likewise Open".
1. at the login screen I have to enter "example.localusername" to login. how can I simplify the login so that the user can choose (click)the domain and just enter the username and password (like the login in windows) or make the domain the default.
2. how can I configure the default user profile? meaning, when the user login for the first time, I want to configure his profile. does it use the "/etc/skel" directory like the regular local login?
I am trying to connect to my Company network through VPN. I use a Lynksys router which is most likely not the problem, as I can get the VPN and Remote Desktop to work from a WinXP Pro laptop connected to the same router. I have tried several RDC clients, none of them establish a connection. The VPN connection is active, I can ping and Traceroute to it , but I cannot get the RDC to work. The RDC should connect to 18.104.22.168 on the company network.
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
Ignoring unknown interface eth0=eth0.
ifconfig tells me
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
so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
I'm getting rather fed up with this Network Manager applet on Ubuntu and its seemingly erratic behavior.I often use my laptop for things like dhcp server to do pxe boot on other machines for netboot installs and other stuff. Often I have to set static address on eth0 etc.I know how to set a static address for eth0 by editing /etc/network/interfaces and all that good stuff, but when I click on the Network Manager applet, it says 'Wired Network - not managed'.I may have deleted it for some reason, but why does it no longer appear, even though eth0 is working?I've also found in the past that changes to interfaces in the Network Manager, such as giving eth0 a static address, do not seem to stick?
I have recently upgraded the ubuntu desktop edition from 8.04 to 10.04. after upgrading i cannot show my eth0 nic interface in the System > Preferences > Network connections----- wired tab. and i also not getting network indication in the top of the panel beside the date time indication. but i can access network and using internet with that lan card. i cant understad my eth0 is connected or unpluged..
I have two connections for my PC, my Ethernet which is on the corporate network and my smart phone on 'usb0'. Both have full internet access.I want to stop my PC from connecting to the internet over the Eth0 while still connecting to internal servers then just have internet over usb0.If I go to the settings of 'Auth Ethernet' in the tray area, under IPv4 there is the routings section - I've tried enabling "use this connection only for resources on its network" but it doesnt work.

It seems the only thing this applet is useful for is connecting to a wireless network.....and only with dhcp !!
I've got access to my LAN and the Internet via my wired ethernet connection. I'd like to share that access with my iPod Touch (device shouldn't really matter) via an Ad-hoc wi-fi network.
This tutorial in the docs seems to describe the right setup but is very out of date (7.04). Instead I found this tutorial and followed it to create the Ad-hoc wireless network. I was able to connect my touch to the resulting ad-hoc network without a problem, but I didn't have LAN/Internet access.What's the next step to get the clients on the ad-hoc network out to the Internet?I found this page in the docs that says I'd need to install dnsmasq-base and uninstalling dnsmasq. I checked and dnsmasq-base is already installed but dnsmasq is not. I do have dnsmasq in /usr/sbin but the package description makes it sound like this should come with dnsmasq. Is the page out of date? Will uninstalling dnsmasq cause other problems?
