Ubuntu Networking :: NetworkManager Is Not Running?
May 20, 2010
I'm using version 10.04 of Ubuntu and for some reason, when I install a copy of Ubuntu or Ubuntu Server, I get a 'NetworkManager is not running' message in the notification bar where the network icon should be.What could be causing this? This is happening as soon as I finish installing the OS and I've not changed anything at all.I've been wrestling with this for weeks, trying different commands and trying different ways of setting up the OS to begin with, scouring the internet for answers, but nothing
Approximately two days ago my nm-applet changed from the up & down arrows to a wireless graphic with a red exclamation point. I lost my network connection. I was playing a video game at the time. I did not install any applications, change the network settings, have any non-included crons executing, run update-manager manually, or reboot my machine within the past 24 hours of this happening.I completely removed network-manager & gnome-network-manager via Synaptic, configured my /etc/network/interfaces file properly, and rebooted. I have my network connection working via the interfaces file.
Then, I found every file I could that mentioned "NetworkManager" and deleted them.I re-installed network-manager and rebooted.e deleted files were re-created upon rebootMy network connection was working because of the /etc/network/interfaces etworkManager was not and nm-applet was showing the wireless icon with the red exclamation point.I have been trying to figure out what happened to NetworkManager. When I click on nm-applet, it says "NetworkManager is not running..." I tried to restart network-manager with the following commands and their respective errors:
Just installed OpenSUSE 11.2 and I have to say it feels great.Only gripe I currently have is the NetworkManager that is starting up very slowly. When I have logged into KDE KNetworkManager applet says that NetworkManager is not running and hence I have no network connection. This is fixed if I start NetworkManager (as root) or just wait a couple of minutes. I have one ethernet interface only, no wireless
I've set-up a Linksys WPC54G v5 wireless card using ndiswrapper and the appropriate Marvell driver. It seems to work ok. On my other laptop running Kubuntu with built-in wireless the routing all works fine - I just get prompted by Network Manager for the WPA passphrase and I'm away. However, when I try to connect to my wireless router on thix Xubuntu-based laptop I get really odd security options.
When I try to connect I get a security prompt asking me for a bewildering array of information. There are four basic authentication options under "WPA & WPA2 Enterprise": TLS, LEAP, Tunnelled TLS and Protected EAP. None of those offers a simple passphrase, they all have some combination of username & password with certificates and keys. If I try to connect to other networks in my area, some do just ask for a WPA passphrase, not that I know them to check!
I have problems with my Broadcom BCM4306 (rev 03) on my HP nx6110ng Karmic.NetworkManager does not list any AP, even if there should be some. It did work for some days without problems, but suddenly stopped working. I made a kernel update with the update manager, but I am not sure if this caused the probem (I also used the wired connection, so I don't exaclty know when wireless stopped working). Reinstalling fwcutter wasn't successful. So I tried as suggested in https://help.ubuntu.com/community/Wi...oadcom_BCM4306 and added the following lines to /etc/rc.local
when i unload and reload my module ath5k, something is setting my wireless interface in managed mode. I suspect is NetworkManager but when i try to kill this process (using -9 parameter) it restarts. how to kill it or which process is starting it over and over again?
Using kubuntu 10.04, I accidentally disabled networkmanager on startup for one of the users of my system. This user now has to manually start networkmanager each time after logging in. How can I make kde run networkmanager automatically again?How this happened: when I started a parallel session as an other user, while already connected via networkmanager in my own profile, kde detected this and asked something along the lines of "There's already a networkmanager running, run networkmanager automatically in the future?" Since I was a little confused, I clicked "no", and that's how things are ever since. I thought there would be some system setting that would allow me to restore this setting, but I haven't found it yet...
Is there a way of wireless networking without using the Gnome NetworkManager Applet? I want to connect to the Internet using a USB 3G modem and connect to wifi without knowing all of the details of every network.Network manager is pretty good but there seems to be no way of using it without starting an X session and it doesn't play nice with any other networking tool and reminds me too much of a Microsoft application.
I've simple PPTP connection in NetworkManager that is build in with ubuntu, once I disconnect the connection [to change IP or so] the connection won't establish again...
I'm getting a libnotify popup that says "Connection failed because timeout"
I'm getting a good IP, I just can't connect again after 1 disconnect... Any idea why?
I installed 10.10 and ran it for a few weeks and then (foolishly) installed Wicd and tried it and it failed. So I had no network connection. Can I re-install NetworkManager from the 10.10 CD? Or is there something else I can try in order to restore wifi access?
The resolv.conf is not written correctly every time i reboot the machine...it seems to ignore all sysconfig configurations !
this is the resoult resolv.conf after every reboot
# Generated by NetworkManager # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx
I'm running ubuntu 9.10 with the latest networkmanager (from ppa)I thought this could be wrong credentials setting, so i've tried a huge amount of setups (user: phonenumber, password: phonenumber, avp:telenor, seems to be the general consensus for how it should be)Is there something I'm missing or is there any way I could tail the output as NetworkManager tries to connect (hopefully seeing something like "wrong password" etc.)
When I start a Kubuntu session, KNetworkManager requires that I type my password to the Wallet before it has permission to connect to the internet. How can I automatically give it permission without entering my password every time?
Code: rfcomm release 0 CHANNEL = `sdptool search --bdaddr=00:21:FE:A5:C9:4A dun | grep Channel | cut -c14` rfcomm bind 0 00:21:FE:A5:C9:4A ${CHANNEL} wvdial e71bt And my /etc/wvdial.conf is configured for AT&T connection here in the US.
Question is, is there anyway I can integrate it with NetworkManager, instead of having to run this script?
There's a "Broadband" option on NetworkManager, but I am not able to get it to recognize my cell phone as a modem. The bluetooth applet only allows for file transfer
Is there any easy way to replace the default Gnome NetworkManager used by Ubuntu with Mandriva Net-Applet? Although I prefer Ubuntu, overall, I have had better luck with video streaming, browser speed, and consistency when using Mandriva (with iPV6 disabled).
I have a tenda W311u wireless with a ra3070sta chipset, i read a lot of tutorials to get it working. I recently had my wireless working but just in NetworkManager. I need to get working in console mode, for example when i make a:
Note: The Essid the same i added in the RT2870sta.dat file.
And therefore if i try a dhclient3 ra0 no dhcp offers received.
Rare, but if i start NetworkManager connected to azcor, and i make a dhclient3 ra0 i get an ip very fast.
I try with cnetworkmanager but is complicated and isnt working for me!
I got it set up in the NetworkManager applet (imported the client.ovpn), but when I connect it sends ALL my traffic through the VPN. I would prefer all accesses to the internet go over my normal default gateway, rather then all the way through to the VPN's default gateway.When I connect through the command line:
Code: openvpn --config client.ovpn I don't have this problem, and accesses to the internet still go over my default gateway on
I have no problems seeing the networks available and connecting to a network in KDE. But there is no network manager in GNOME. I might have messed up with the settings earlier. What I can do though is run knetwork manager every time I start up (or add it to start up programs). But that opens up the KDE wallet which would rather avoid.I am thinking I need to install something related to NetowrkManager.
if the NetworkManager uses wpa_supplicant? I normally dont use NetworkManager and decided to try it. I started it and tried it out and it works with WEP and WPA! I cant figure out why using the iwconfig command is not working by itself for WEP. WPA working with NetworkManager is just a bonus though.
I'm an inordinate amount of trouble getting F15 to run without NetworkManager. If I boot with the NetworkManager service enabled, my NIC presents as expected at /dev/eth0 (I'm using biosdevname=0). However, when I stop the NetworkManager service, /dev/eth0 disappears from the filesystem.If I boot without NetworkManager enabled, /dev/eth0 is never created. Reviewing dmesg, udev is loading an ethernet driver.
I'm using CentOS 5.4. I want to set-up a PPTP connection (I'm the client). I installed the NM pptp plugin from EPEL's repository. I have configured my PPTP connection in the NetworkManager applet but now I don't know how to connect to the server, I mean, there's nothing like 'Connect now'.
My networking seems to be OK but when any changes are made the NetworkManager Applet 0.7.996 (I think) in the panel pops up a small window ~ 300*80 pixels which displays some faint coloured lines and dotted lines where, presumably, there should be a message of some form. How can I configure it to get the message?
set the number of retries networkmanager attempts to connect to a network to infinity?
I live in an area of Australia were wired internet dare not tread (or so say the ISPs). My only real choice is 3G wireless broadband, and even that is iffy at times. Often late at night the network towers do "something" (reset, maintenance, etc. - no idea) and the internet drops out, networkmanager tries to reconnect, fails, tries again, (etc. etc.) until it ultimately gives up, requiring human intervention when the towers are done with whatever it is they are doing. This happens frequently, and I'd like to have networkmanager keep trying "forever" until it connects so I don't have to restart the connection each morning.
Where would such a thing be set? How does networkmanager know when to give up?
i have added a vpn connection on my Lucid desktop machine, but every time i try and connect, it fails. I also have the same, identical vpn connection on my karmic install on my laptop. everything works perfectly on Karmic, but Lucid is having problems. I have followed identical steps for creating the vpn connection on both machines: vpn connections can be made in 2 ways, the first is through the network manager, but trying to connect through the nm-applet returns an error about vpn failing to connect and "no valid vpn secrets".
I suspect this is at the root of the problem. The only way for my Lucid machine to successfully connect through the command line is if I run the openvpn command under sudo.
i'm realatively new to linux am just getting my head around the command line, any way my problem today is, my network connection and networkmanger program have been deleted/uninstalled after i did a system update. im running ubuntu 10.04 32 bit. I have run of some commands which should be able to tell you whats going on. at the moment i'm using a live ubuntu cd to gain net access.
so the question is How do i restore my network connection and get my networkmanager program back without a internet connection. (i can download stuff to a memory stick and do manual install) Hope someone can shed some light on this, i know this topic has been covered before although each case seems slightly different to mine.
I'm trying to get KNetworkManager to run a script after my wireless connection is activated. I created the script in /etc/NetworkManager/dispatcher.d using the same format as scripts to start firewalls, but it doesn't seem to run. I can run the script successfully from the command prompt, but it doesn't happen automatically
I have a ZTE 3G USB modem (MF645). When I plug it, 5 devices appear: /dev/ttyUSB[0-4]. The modem device is /dev/ttyUSB2, and I can successfully connect wvdial on it. NetworkManager detects the modem, however, it tries to connect to /dev/ttyUSB1 instead, and fails.
How does NM decides which device to connect to? Is it possible to instruct it to connect to a specific device?
