Ubuntu Networking :: Check The Network Connection Applet, It Display Active Information Of Eth0?
Jun 7, 2010
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.
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".
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)
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'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This tutorial in the docs seems to describe the right setup but is very out of date (7.04).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?
I'm running lucid 10.04 on my netbook (regular desktop distro though). I enabled the proprietary drivers needed to get wireless working (I have an hp mini 110 by the way), but the applet in the taskbar will never show a connection, even if it is connected.
I have my ubuntu box hard wired into my network. It all works fine, until I reboot my ubuntu box. After reboot, it can no longer see the network. I have it set up with a static ip. Not sure that I set it up completely correctly but it works fine...when working.. To fix the problem, I enter terminal: ifup eth0 That fixes all know problems until next reboot. What do I need to do so that it will remember settings and automatically be hooked into the network at power up?
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?
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 :/
Code:
* Stopping the Firestarter firewall... eth0: error fetching interface information: Device not found eth0: error fetching interface information: Device not found eth0: error fetching interface information: Device not found
I have been running into network issues lately with my CentOS 5 (installed on AMD Athlon X2 - 64 bit machine about 2 years ago). It was able to connect to the network fine until yesterday when I installed more memory into the machine restarted it.
Upon restart, the boot up was paused at 'Determining IP information for eth0' step for a while and booted with out connecting to the network. I tried restarting the network (/sbin/service network restart), but this is the error message I continuously get: Determining IP information for eth0...PING xxx.1.226.1 (xxx.1.226.1) from xxx.1.226.83 eth0: 56(84) bytes of data
I've seen this pop up a few times on the forum but my setup is slightly different. I have a PC with an ASUS P5N32-SLI Premium motherboard. I've just installed CentOS 5.1. Yes, I know this is ancient, but this is what they're developing on at work. I'm trying to get connected either via ethernet or wireless and neither one works. When I boot the computer to Window XP it does connect on ethernet. Ethernet should be easy so I'm concentrating on that. But I get "Determining IP information for eth0... failed." after a 'service network start'.Here is some other information that was asked on similar threads:
I use network manager applet 0.7.1. I had set the automatic wireless connection to my my wireless network (WPA key secured). Recently, I get the following problem: At the automatic connection, I get the message: Network manager applet (/usr/bin/mn-applet) needs default keyering. As I don't know what it is to type it and then, deny or OK, it doesn't get connected to my wireless network.
i have been using ubuntu for just over 3 months now and i completely love it. but heres where the problem starts (and please let me know if i am in the right topic) i recently installed ubuntu 10.10 on my roommates computer, the reason being is that the IT department here on college "fixed it" for him, now it wont connect to the internet. it will however connect if we use an ethernet cable from the other laptop to his. his had originally windows xp then got upgraded to vista. i was wondering if there was a way to completely reset the networking wifi card if that might be the problem.
my roommates computer is a DakTech PlaidBook, however i do not know on how to check the system information in the terminal to tell you what wifi card he has and such, all i want is to have internet back on his computer again.
When I log onto my Ubuntu 9.04 boot I am disconnected from the internet, on my windows 7 boot It works just fine, I have attempted disabling networking, power cycling the modem and router, and re-enabling networking, no dice though. hovering over the connection icon tells me that there is no network connection.
Opening the edit connections window tells me that there a wired connection called Auto eth0 that is set to never, and that is all that I can find. I hunted for other forums on this and found a few but none with a successful resolution.
I have a successfully connected VPN connection. When hovering on the networkmanager applet it show beside the wireless connection also the connected VPN. The icon also changed from staircase-bar to staircase-bar with forelock. Oh yeah I'm using GNOME desktop.However when right-clicking on it and choose Connection Information I can only found tab for the wireless connection. How can I have the information tab also for the VPN connection, showing like IP address and gateway used?
I'm using 11.3 gnome and cannot fix the eth0 connection. Tried to make it work with connection manager, ifup but both of them did'n make eth0 work. Here are some logs that you might wanna see:

I have TP-LINK router that sends wireless signal through the house which I'm using on my laptop's Ubuntu to connect on the internet, also I can connect with Ubuntu from laptop via the same cable that I'm trying to use on my desktop, so the router and cable are working. Also on my dekstop I've installed Windows 7 and can't connect from there either. The computer is new so i doubt that there is something wrong with its hardware. It all started when my connection disappeared. My ISP advised me to reset my router by plugging out the power cable and plugging it back in after 5min, and so I did. After that I could connect only from laptop. Tried to reinstall suse, to install ubuntu, but nothing worked. When I installed suse on my friend's computer, the only thing that I had to do is to open YaST and change the Network setup method from ifup to the NetworkManager, and also insert the MAC adress in the connection's properties. Tried that on my computer, but also didn't work.
After rebooting, I found that the server couldn't see the network. The machine has dual gigabit ethernet (eth0 and eth1). eth0 is connected to the internet, but disappeared. ifconfig used to show eth0, eth1, and lo, but now only shows eth1 and lo. If I boot into rescue mode I can get internet and ifconfig returns eth0 and lo. Any ideas on how to fix this? I apologize in advance if I ask any noob questions. I'm not a very experienced Linux user.
I'm trying to write a program which would get information from a webpage and display the information on my desktop sort of like a widget. I kind of remember there being something like this already made, but for the life of me I can't remember what it's calledDoes anyone know?
i have huawei usb stick modem, i'm connecting to internet with wvdial command, i have configured the file "wvdial.conf" to be able to connect, everything works fine i guess but the update applet still show me the message
Code: Unable to check whether updates are available
connect to the internet and connection manager too .. it tell me i'm not connected, i think i must configure my connection in an other way .. but i don't know how ..
I have been playing with Linux consistently for a couple of months now. I've been a Windows sys. admin for most of my career, so Linux is pretty strange for me. I started off with computers way back with the TRS-80 and then eventually moved to DOS systems. So the command line interface (CLI) of Linux was not completely alien to me, yet my lack of knowledge on the syntax and commands is holding me back. I have come a long way.
Recently I needed to play around with some DNS settings and one of the commands I used frequently in Windows, IPCONFIG /ALL, doesn't have a direct relative that displayed the same information. If you run ifconfig, it doesn't return the DNS servers you are currently using. You have to run a separate command to retrieve that information.
What I have done is created a super simple script that displays the network information for my primary LAN adapter, which is ETH0 in my case. After that, it shows the domain and name server information. Then it pauses for 20 seconds before closing the terminal window.
Here are the contents of the script file:
ifconfig -a eth0 cat /etc/resolv.conf sleep 20
I simply right-clicked the Linux desktop, choose Create Document, Empty File. I named it something like Network Info. Then I opened it and put this information in it, saved it, and closed it. I renamed the file and added a .sh extension to the end which makes it into a script file. Next, right-click the script and go to properties. In the Permissions tab, check the box next to Execute: Allow executing file as a program. Then click close.
To run the script, just double-click the icon and then click Run In Terminal at the prompt. The terminal window opens, displays the information, and exits after 20 seconds. If you need it longer than that or need a different interface (such as wlan0 for your wireless), you can change or even add that in.
This was all done in Ubuntu 10.10. I know it is very simple and very straight forward and welcome thoughts and feedback about simpler ways to do this. For me, the old-school Windows admin, it's a baby step in the right direction. I am really enjoying learning the Linux OS.
I recently setup a new SUSE box for the purposes of acting as an ftp/sftp server. It's currently setup to run ProFTPD 1.3.3.rc3 and mod_sftp/0.9.7. The server has two internal network interfaces eth0 and eth1. eth0 is purely for internal use to accept ftp and ssh. eth1 is outward facing and receives connections from the WAN via SFTP over port 22. The problem I am facing is that after half hour to an hour eth1 stops accepting connections whenever there is no SSH connection present on eth0. I can't figure out why this is happening.
ProFTPD is setup as follows: SocketBindTight directive is on, default server and port are commented out.
[code]...
When the external interface is unreachable the proftpd and proftpd-sftp logs show no record of any connection attempt. I have noticed however if I leave eth0 down eth1 stays contactable without problem. Can anyone give me some pointers on what I can check to find out why this may be happening.
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?
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:

so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
I'm running a fresh install on an intel i7 system on an asus p6t deluxe v2 motherboard with the onboard NIC (Marvell Technology pci-e). I know the NIC is working as when I boot into the onboard OS that Asus provides (Asus Express Gate SSD)I have a working net connection.Booting up CentOS hangs at determining IP information for eth0 and eventually fails with the following error:PING xxx.170.30.1 from xxx.170.31.231 eth0: 56(84) bytes of data---xxx.170.30.1 ping statistics ---4 packets transmitted, o received, +3 errors, 100% packet loss, time 2999ms, pipe 3 failed.
