Ubuntu :: Network Manager To Configure Eth0 Interface - File Does Not Carry The Ip
Mar 31, 2011
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 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.
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?
today I tried to configure a network route to a host for testing my network interface. Code: route add 192.168.1.15 eth0 As I have to eth interfaces and both interface got their IP from DHCP (192.168.1.11 and 192.168.1.12) and are in the same subnet, I shut the other interface down:
Code: ifconfig eth1 down Then I tried to test the interface by doing a ping to 192.168.1.15. Problem: When I unplug the cable from eth0 (and eth1 is still plugged) the ping still works. Somehow my linux (it's debian) powers up again eth0 and pings over this port.
How can I stop my linux doing this. I just want to have the route added only on the one interface - not the other. Is it maybe some case of a default-gateway?
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?
Should I be able to see eth0 in the Network Connections control program that ships with Kubuntu?Its not there. See screen-shot.eth0 definitely exists and I can access the Internet no probs but it doesn't show in the above.
My network name is eth2 it was changed by some reason and now i got these errors... i installed, reinstalled, re re installed, tried to run the asistant but no luck :/

I'm running Fedora 12. I've been using Amahi for a trial but this blew up. Last attempt to use it flagged up a problem with Ruby on Rails release version incompatabilies. I've removed Amahi using the software toolk. I now have no internet access and no ETH0 in network manager. How do I get my ethernet back?
i'm trying to install virt-manager , to run a couple of virtual machines, i created a virtual nic vnet0 and bridged it to my eth0, i have configured the /etc/network/interfaces file with proper static ip, but i beleive the network manager is renaming my nic to eth1 and causing all kinds of problems. I uninstalled network manager and now i can ping anywhere in the network, but not outside it. ie google.com
Config: Squeeze, 2.6.32-5-amd64I just installed squeeze and the network is up and nm-manager deamon if working but the Gnome applet doesn't seem to work as usual. It indicates no network although the network is available as indicated by ifconfig and route below. When I switch WiFi on, the nm works flawlessly. When I click on the applet icon it says "Wired Network: device not supported" (or similar, msg in french is
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.
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 inet6 addr: fe80::21f:16ff:feba:4c8c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I'm running Kubuntu 10.4. My problem is that Network Manager keeps defaulting back to Auto eth0. I have created a new wired connection and set my manual addresses. I have ticked the 'connect automatically' button. Every time I reboot or wake up it reverts back to Auto eth0.I did have wicd installed but this was not reconnecting after wake up (said it was connected but I couldn't ping etc), this is a pain also.
I have a troubling networking situation that is compounded by the system being remote without any out-of-band mgmt in place nor a serial connection - but am relying on a coworker entering commands into the terminal for me, or doing stuff in the GUI I have an FC12 i386 install running, that was up and stable for 6 days. Primarily this was only being used for a deployment of nTop. Up through Monday evening, I was connecting to the system (in NY) via VNC (here in SF), and was successfully watching nTop do its thing.
Tuesday morning, I go to connect to SSH and I can't get in. The NAT translation is still in place on the firewall, but there is no connection to the NIC/eth0 from the router. This is what I've had my coworker run:
I was going to try and have her run the /sbin/mii-tool eth0 tomorrow a.m. just to verify that the interface isn't physically bad? But this is a brand new desktop, and I can't for the life of me understand why this interface went down. I also have the internal IP on a DHCP reservation, which is the same IP listed in IPADDR in the ifcfg-eth0 file - could this be a problem? should I remove the DHCP reservation? I did this so I could SSH to a public IP which I have NAT'd back to the internal 10.0.x.x address I had my coworker take a look at the GUI, and the eth0 properties are "inactive" and the "Activate|Deactivate" buttons are greyed out.I suppose I can have my coworker grab the /var/log/messages and copy to a USB drive, then email me that from another workstation.
If I made a distro from scratch it would have been Lubuntu, cept I'm sure my theming would have been horrible. Now Ive installed on a couple of my Laptops, and even had a few friends convert, and for the most part everything is hunkus doris, cept one small issue thats keeping me from slapping it on my trusty laptop. I'm lost as to what the problem could be. Ive tried just about all I can think of, but I use sprint mobile broadband to connect to the net and then use Network Manager to share this connection with the laptops and Palmtops around the house. I can get my sprint modem to connect thats not a big problem the problem is now I cannot get the Auto Eth0 to connect to send out as a share. It just refuses to connect. Now this is not a Lubuntu problem at all Im sure its somehow a Lxde problem, as Mint Lxde, PeppermintOS, and so on do the same thing, refusing to connect Auto Eth0 while Sprint is connected. Any Gnome based distro this works flawless, as does Xfce distros, so Im sure this is somehow something within Lxde. Im sure its down to just "missing" a file or some stupid overlooked thing.
i have ubuntu 10.10 and i want to configure my interface eth0 with the commande line with owner (not the Root)$ifconfig : this commande works and listed all interface with some description -> thats goodbut when i use some parametre like @ip and netmask
I want to use a static ip address on my wireless network but when I click configure in network tools it keeps telling me The interface does not exist and to Check that it is correctly typed and that it is correctly supported by your system
Network manager doesn't recognize nas0 interface and i have problems with using Gwibber, Evolution mail,Empathy, etc Is there any way to add nas0 in Network manager?? I know the solution to remove Network manager, but i need Network manager because i'm often using wireless (as second internet connection).
Im new in this world of linux and suse. I have just installed the opensuse 11.2 in a Dell Inspiron 5160. Such laptop has a BCM4306 Wireless LAN controller. When I tried to configure a wlan connection, I found that the firmware was not installed. After looking in different forums, I installed the firmware b43. Now, my wlan card is abled to find the wireless of my router.
I have tried to configure a connection with YAST as well as with Network Manager, but both cases failled. Specifically, when I use Network manager, Im able to see in the applet my connection, how strong is the signal, but I see a yellow symbol (in one forum, such a box is shown with a green symbol).
I have check many time all about the secutity, encryption, and so one and all seems to be correct. But when I open the mozila firefox or the konqueror browser, no chance to surffer in internet. Now Im just a step to become crazy. The drivers are ok, the information about the router and the keys are ok, but in such a way, I am still harmloss.
I have just installed opensuse 11.3. I am absolutely new for Linux and for this forum. I have tried to open Network manager to configure my wlan. But its not starting. How to start network manager and configuring my wlan.
I have a work desktop plugged into the work network. As I opened my firewall settings I noticed that it is turned off. My question is how should I configure it? I saw that the interface isn't assigned to any zone... I should assign to internal zone and open some port that I need in order to work? There are some guidelines for configuring the firewall?
i install kernel rpm after i boot that kernel network not working kernel name : kernel-rt-trace-188.8.131.52-132.el5.centos.i686 [URL] error "Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring."
Installed a TP-Link TG-3269 Gigabit card in a machine running OS 11.3 32 bit, when I go into Yast, Network Devices, Network to try configuring the card I get this errormsg: Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details. Couldn't find any mention of the card in dmesg's output, (though the 8139 onboard card is in there) there is some stuff about pci host bridge but I don't know whether they would be relevant or not
The chip on the card says it's rtl8169sc but lspci lists it as being 00:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Device 8369 (rev 10) Done some googling and there don't seem be any drivers for a Realtek 8639 and it returns no matches from a search on realtek's site, but there is a driver there for rtl8169sc chips, which I downloaded and installed, no errors when installing it Even after a reboot I still get the same error in Yast's Network Settings screen, lspci still lists it as 8369 and the device isn't listed at all if I run ifconfig
I just installed lxde on an ubuntu lucid box and after logging into it I found that the network manager applet doesnt start automatically and hence no internet connection. Though I could easily setup the net using ifconfig, I want to use network manager as this pc is used by my brother whos a beginner. In the terminal if I give "nm-applet &" the applet starts and the notification daemon states "connection established" but still internet is not available. So how can I configure the network manager in lxde?
I'm trying to configure internet access using KDE network manager. Added new VPN pptp connection, set gateway and other options but manager tries to connect for about a minute and breaks then. Here is /var/log/daemon.log
Code: Jul 1 17:35:22 dvinokurov-desktop NetworkManager: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'... Jul 1 17:35:22 dvinokurov-desktop NetworkManager: <info> VPN service 'org.freedesktop.NetworkManager.pptp' started
As I understand the main problem is in "(IP Config Get) timeout exceeded".
Configuration: Kubuntu 10.04 x86, VPN server with MSCHAPV2 auth, no compression, no encrypting.
I'm trying to connect to the VPN of my employer; after fix various minor issues I reach this point in which the DNS entries and the default gateway of the VPN are overwritten with the values of the eth0 device that appears by default. Therefore the vpn is not useful.
