General :: NetworkManager 0.8 Auto Configuration Not Working
Jul 11, 2010
I just installed Linux for the first time and I'm having some internet connection issues. I am running Linux Mint 9 on my HP 210 netbook. I am unable to connect to anything using NetworkManager 0.8's automatic configuration. I can't even ping my other computer. Both computers are connected to my cable modem by a switch. The other computer (the one I'm on right now) is running Windows Vista and is working fine.
eth0 is getting an IPv6 address assigned to it, but no IPv4 address. When I do dhclient (I'll include it at the bottom) it says no DHCPOFFERS received and then makes another adapter called eth0:avahi with an IP of 169.254.9.78, which I think I understand from what I read is just a default.
I noticed when I looked at the ipconfig results from my Windows computer that there were a number of things called tunnels on there. My ISP is cox, and I saw some other people with cox had the same setup. One of the tunnels seems to make it so IPv4 and 6 can coexist. Could that be a problem? When I asked Cox why it was set up that way they helpfully referred me to wikipedia.
Here are my ipconfig (from windows), ifconfig, and dhclient results. Let me know if I can provide any other information.

I have no idea how I managed this, but I am able to connect to the internet but NetworkManager doesn't show any connection. This means that until I kill it, I cannot log in with Pidgin, because it is waiting for a connection.
Do I disable NetworkManager completely or do I try to make it recognize that I am connected to the Internet? If the latter, then how should I go about? (Please let me know which files I need to show you, because I know I've messed around with a couple).

I understand that Fedora 14 using automatic printer detection. When i plug in my Epson DX4450 printer nothing happens and i can find no way to configure the printer. This has never been a problem with any other linux distro. How can I correct this problem? Why does auto printer detection not work?

I press On-button, Debian boots, logs in and automatically connects to the Wireless network AND! to my local pc via LAN. It runs an ssh server, so I can ssh into debian over internet and communicate with the local pc (send a magic packet).Here are my problems:
1) I don't how to log in automatically. This and this doesn't work.
2) I need a network tool that can manage multiple connections and has a reconnect feature. With the default network manager I cannot even connect to more than one network simultaneously although I have two network devices of course.
And I guess I can run all that in console mode, right?

The auto connect feature of NetworkManager Applet (version 0.7.997) isn't working on my system. If the WiFi connection dies, Network Manager doesn't detect that the connection has been lost and try to reestablish the connection. I have to manually click on the WiFi hotspot to reestablish the connection. This appears to be the case both while the computer is running and when I first boot it up (i.e. when booting, if the first attempt at establishing a WiFi connection doesn't succeed, Network Manager doesn't retry or try another hotspot).Is this "normal" behavior for Network Manager? If not, does anyone know a fix? Here's some more info about my system:
Computer: Dell Inspiron 1318 laptop
WiFi Chip: Broadcomm BCM4238
Kernel Version: 2.6.31.12-174.2.22.fc12.x86_64

I'm using Red Hat in a work environment as the system that runs my Netbackup. My predecessor was using 1Tb Western Digital external HD's and they worked great but now were upgrading to 2Tb drives and I have to format them and make sure then work correctly.
I have been able to format them in Red Hat and they have worked with Netbackup however the only way I can get them mounted is by having them plugged in and then restarting the whole system. The older drives are completely plug and play.
Here are the steps that I have been following;
Then I set the file system type with;
Next I create the new filesystem on the drive with the command;
Then I finalize the format with;
Followed by a restart, which of course the drive comes up. But if I unmount the drive and remove it and then plug it back in nothing comes up. Trying to manually mount it doesn't come up with anything. I have attempted this with 3 different brand new Western Digital external HD's.
I've looked in the fstab and when I plug in the old hd's it comes up with the command to mount it. With the new one's its not there unless I do the complete system restart.

I have an OpenVPN connection set up in the NetworkManager, and it works fine when I click on it to activate it. I would like to have it start at login, and I cannot find a way to get it running automatically at login, just after I connect to the local network.

I am using Debian 6.0 and I am trying to auto login into Debian 4.0. I generated rsa keys with ssh-keygen on Debian 6.0 and I copied id_rsa on Debian 4.0 in /root/.ssh/authorized_keys. When I tried to ssh from Debian 6.0, ssh is giving the following error and asking for password. how can I solve the problem to perform autologin?
Error: Agent admitted failure to sign using the key.

I just updated to a new Kernel, in Squeeze. So far everything seems to be working properly but NetworkManager. It shows that I am not connected but I obviously am because I am posting this thread. When I click on the icon in the bar by the clock, with active applications, it does not show any networks available, even though I have wireless and networking enabled

It was working until a recent update. I have the icon in my system tray. Networkmanager is running. I have tried to reboot the computer and restart the network manager. All switches that could turn the network off is on. Every time I click on the icon in the system tray it tell me the networkmanager is disabled.

I have recently bought a branded Onda MT835UP USB broadband modem. The hardware comes with its own drivers/GUI for linux, however I'd rather use the Debian-provided NetworkManager+modemmanager packages.
A few details:
- I'm using debian unstable,
- latest NetworkManager 0.8.2-3 from experimental
- latest modemmanager 0.4+git$foo from testing
- latest usb_modeswitch[_data] from experimental

I upgraded to 11.4 from 11.3. What I tried:
There is that twisted "N" symbol: clicking on it gives no response (but the mouse cursor is changed when over the menu bar).
Sometimes (not always(!), no pattern found when) the little cell phone symbol in the tray is there although hidden in a sub menu. There I can activate networkmanager but I then get a popup saying that network is already running do I want to start it by hand or automatically? Nothing happens clicking on either choice.
Starting from command line has no visible effect and no errors printed.
How should the connection be established? Where can I enter my parameters? (This is a 3G mobile connection).

On fresh install of 11.4 everything worked fine, but after some updates networkmanager stopped working properly on my netbook (intel atom n270 based).When I log in, network manager shows that networking is disabled and I can't connect. Checking/unchecking the checkbox does nothing. All settings in Yast are OK.To make it work, run "/etc/init.d/network restart" and then plug in the wire OR (in case of wireless connection) I restart network from console, unchecck and check the checkbox in networkmanager and only then it starts to work as it should.

I've run into a situation where knetworkmanager tells me networking is disabled. If I switch to the ifup method in Yast then I can get online but when I switch back to user controlled knetworkmanager tells me that networking is disabled.I've actually had this happen twice.The first time I somehow managed to get it working again (I thought it was by right clicking on the icon in the system tray). This time I don't see the same option.Has anybody got any suggestions on how to get knetworkmanager working again.

I just got my Airlink AWLH5025 to connect using the instructions provided by Gentoo Wiki's article on Wireless Networking. I'd like to use NetworkManager, but I'm running into problems - launching it kills my connection, and even though it finds my network it won't connect to it.

I am currently running openSUSE 11.2, but I do not like the KDE4 interface. I downgraded everything back to KDE3, but kept the KDE4 artwork. The NetworkManager program under KDE4 works fine and can connect to my home wireless network. However, The previous of NM cannot cannot connect to any wireless network.
I find it kind of odd, since KNetworkManager is just a frontend to the real NM, with was not actually changed when I downgraded.

I managed to kill KNetworkManager today and I'm not sure what I did. This is a netbook running openSUSE 11.4 with all updates applied and KDE 3.5 (from the openSUSE repository). Normally, I use knetworkmanager to connect to the Internet. Everything was working fine this morning and today I decided to apply whole disk encryption (using cryptsetup and luks) to it.
So, I backed up the files, encrypted the partitions, made some adjustments to /etc/fstab and /boot/grub/menu.lst, and copied the files back. Everything is working fine, except for knetworkmanager. When it goes to connect, it starts off with the "gray Earth" (to represent no connection) and then it switches to the "connecting" icon for a fraction of a second, and then it's back to the "gray Earth". Looking at the output of iwconfig, it hasn't connected to the router at all (the essid is blank).
The connection works fine using ifup. I tried using cnetworkmanager (the console version) and it spits out errors like this:

Until 10.10 the NetworkManager applet/widget has not been able to:
- edit the default "auto eth0" network profile
- create/edit system wide network profiles (wired, wireless, mobile broadband)
The networkmanager itself can do it, of course, since long. The GNOME/XFCE counterpart also used to work flawlessly since long.

I code primarily in jQuery/JavaScript, and I'm looking for a text editor for Linux that has auto-indent and auto-outdent (seems to be tough to find that). Any suggestions? I've checked Gedit, Cream, vim, Bluefish.None of them seem to have this feature.

I've had 11.4/KDE working pretty well on dual boot Asus G73SW for a few weeks now. Only issues were the FN-* functions that control keyboard lights and whatnot but no biggie since the essential worked.The last couple of days the update notification was indicating 1,201 updates to be made. Yeah it seemed extreme but I googled around and checked the forums and there was nothing related. I figured I might be missing some packages since I installed from the live KDE CD (still 1202 updates!!!???). So I updated. Big mistake!!!!! Ever since NetworkManager cannot connect to the internet, be it wired or wireless.
Initially it could not even see my home network but it picked it up after I removed the plasmoid from the panel and reinstalled it. However it doesn't respond when I click the network icon and still no connection.I managed to get eth0 working with ifup but not wifi. The last part of network manager log file is quoted below. I can send the whole thing to whoever is interested. I can't make sense of it but maybe someone on the forums can.

The apt-get autoremove command, I use Debian 8 for some time now and I often install a package, test it for some minutes and remove it then. I noticed that in most cases (if not all, I'm not completely sure) all the dependencies that were installed with the package (mostly libraries, of course) stay installed on the system when I remove the package.
And there is no output of apt-get that there are unnecessary pacakges which I can remove with apt-get autoremove. The autoremove command does nothing.Before I changed to Debian, I used Ubuntu and there all the dependencies are removed with apt-get autoremove when I uninstalled a package.My question is now, is this normal? if there are fundamental differences in which packages "autoremove" removes between Debian and Ubuntu?

I have a "time-server". It's sending time to different devices through different ports/protocols. The problem is that it has no operator and that makes some extra difficulties.
Now when i try to start it using terminal Code: Select allsudo ./myprogram works fine and
Code: Select all./myprogram doesn't work.
It is so because without sudo i have no access to ports. As a result If i add my program to System->Preferences->Startup Applications it has the same problem. So i need to start it as root, auto-start, right after auto-login to system but without entering password cause nobody will do it.
Also I need to start ntpd but it also asks password sometimes I've tried googles but it offer a few ways with entering password that isn't suitable for me or writing some scripts/changing system files but with no example I'm afraid to break it all. So is there a way to start Myprogram and NTPD as root with no password entering?
My system is Debian 6.0.10 Squeeze, Kernel 2.6.32-5-686

I can use this at the end of bash_profile to autorun start x after logging on. code...
But what about to auto logout after killing the X session? I hit exit from fluxbox, but I could add a menu item I suppose to just kill the xsession. Wondering if there is a graceful way to do it with bash_profile.
Also, on a related note, if I switch to dash with the bash_profile method still work?
