Networking :: NetworkManager Not Reliably Starting Interface Directly Wired Between Two Computers?
Jun 22, 2011
I have two computers that have a direct ethernet wire between them. The interface is set to a static ip address on each side, and under control of the NetworkManager.
About 1/10 the time the interface does not start. The messages log file will show:
Jun 22 13:01:22 owl10 NetworkManager[601]: <info> (p6p1): carrier is OFF
Jun 22 13:01:22 owl10 NetworkManager[601]: <info> (p6p1): new Ethernet device (driver: 'r8169' ifindex: 2)
Jun 22 13:01:22 owl10 NetworkManager[601]: <info> (p6p1): exported as /org/freedesktop/NetworkManager/Devices/0
[Code].....
So, I imagine there is a race condition where both boxes wait for the other to start the interface.
My question: Is there anyway to force NetworkManager to bring up an interface even if there is no Carrier?
BTW, this problem started recently on Fedora 13 after some upgrades. We upgraded to the latest Fedora 15 to try and solve it, and it now appears more often than it did on Fedora 13.

I cannot connect my Dell Inspiron 1300 through the NetworkManager "wired" connection, when I try to go direct to the cable modem. It fails to connect.
If I connect the cable modem to my (linksys WRT54GS) wireless router, and then connect my laptop to a wired port in the router, it connects in seconds, successfully.
This has happened to me 2 other times, when I tried to connect my laptop to a client's cable modem, because my client did not have a wireless router available, in their home.
My wireless works fine. This has me perplexed. I'm using Ubuntu 10.04 LTS and NetworkManager Applet 0.8
I've tried some things to see what is going on, such as "ifconfig" "dhclient" as well as modifying the "Auto eth0" parameters and adding my laptop's MAC address, etc. Results were no fix or solution. I feel like I'm headed down the wrong road. Would someone set me straight? I have a feeling this is simpler than I think.
Do I have to actually reset my own or someone's cable modem to get this to work? I don't want to do that unless there's no other way. Is there? Let me know what commands I can or should run.

First I must say I love Ubuntu Netbook Remix. I purchased an Acus 1005HAB Eee PC last week and immediately installed UNR. The redesigned Applications menu is awesome. I've had a few bumps here and there, mainly with the internal mic (wanted to use Skype). In an attempt to get the internal mic working, I installed some of the linux-backports modules as instructed by some of the forum postings here. It seems as though installing the backports modules may have affected my network interfaces, as they now act funny after resuming from suspend. The wireless comes back, but just says "device not ready" (not worried about wireless right now). However, the wired interface won't come back at all after suspend. I must reboot the machine to get eth0 to be recognized.
I read through lots of forum posts about similar issues, but most of them had to do with the wireless interface, not the wired. I saw some posts talking about adding SUSPEND_MODULE instructions to some /etc/pam.d files, but I got the impression those were for NVidia network cards, not the internal cards present in the Eee PCs. I purged the linux-backports modules I had installed for Alsa (mic and speakers) and rebooted the machine, but still have the same problem so now I don't know if that's what caused it. Both wired and wireless were working flawlessly after resuming from a suspend when I first installed UNR, so I know it's possible!

I've been working on a koala system, trying to set it up as a wireless AP with a pair of wired interfaces. The hardware itself is a small Nvidia ION platform with a built-in NIC and a bunch of USB ports, so I decided to set it up with a single wired USB NIC and a wireless USB NIC. For wired, I settled on a TrendNet TU2-ET100. Initially, this NIC worked perfectly on with no hackery required, plugged in and off it went, assigned as eth1 on the system.
For wireless, I've tried a couple of different units, both of which required use of the compat-wireless drivers to get recognized. I'm still having problems with that, but I'll deal with that later. In building and installing the compat-wireless drivers, it appears to have messed up the included drivers for my TrendNet USB NIC. Now when I boot the box, it comes up with the following error:
And from there, the NIC won't show up any longer - no eth1 visible in ifconfig -a. Clearly, some alternate driver (usbnet?) from compat-wireless has messed up the asix driver from being able to start up. Any ideas on how to get that restored?

I have a bit off a strange one here, my internet stops and starts. One minute it is fine and the next it will not connect to any web pages or even to the router then its fine again. My machine is a new build Pc were I installed 11.04 as a fresh install, everything was fine till a few days ago when this all started up. I connect to my router via a wired network, the new PC also has a second HD with windows 7 on it and that is fine with the net so I know it must be some sort off software issue but I have not idea what.
Machine setup
Intel 3.3GHz i5 core
4 gig RAM
GeForce GT 220

I have a problem with my F13 and wired connections on my Acer TravelMate 2410. When I connect the inet cable it doesn't show it as connected. When I type ifconfig, it shows everything as it should. When I tried to bring up eth0 with ifup eth0, it said that the device is not managed by NetworkManager. I tried to restart nm with service network restart, but it gave this error:
Shutting down loopback interface: Error org.freedesktop.NetworkManagerSettings.InvalidConn ection: ifcfg file ;/etc/sysconfig/network-scripts/ifcfg-lo' unknown
The same error came up for eth0 and Wired_connection_1 (the connection I configured from NM )
When I typed nmcli dev list it gave me:

I need to use some PCs located on my university from home through the internet. I am using a program called Teamviewer [URL]... The problem is that this program transmits the whole graphical interface, which is slow, but I just need to use the command line with these computers. I am aware of ssh, but my university won't give me access to theses computers over the internet.

I have a wireless connection to the internet, as well as a wired connection to a local network. When the wired connection to my local network is enabled, the wireless connection to the internet no longer works until I disconnect the ethernet cable.
(This setup used to work just fine when I was using Windows, but now doesn't seem to work. I wasn't using IP aliasing in Windows, but I am now, which may be causing the problem.)
My original connection to the internet was a wired one, at eth0, so once I got wireless enabled (on eth1), I created an IP alias to my local network of eth0:1 which is a static IP on my local network. The only configuration I did at all was to add a file named /etc/sysconfig/network-scripts/ifcfg-eth0:1, with the following contents:
Code:
And NetworkManager just seemed to pick it up automatically - I didn't change anything else in NetworkManager or anywhere else.
(Also I use 'service NetworkManager start/stop' entirely rather than 'service network start/stop' to manage my connnections. i.e. I did 'chkconfig network off' when setting everything up initially.)

Should I be able to transfer files between computers wired to the same router? Is the router bridging function used to transfer data between wired computers? I just got DSL and I'm new to networking. I have openSuse 11.4 on two computers plugged into a Belkin router. The internet connection to my ISP works from either computer. If I ping $HOSTNAME from either computer, the hostnames are different, but the IP address is the same which is that of my ISP. I only have the one router, but it has a bridging option. I don't know if it can do both bridging and routing simultaneously.

I was having a problem with cairo dock, asked on the board how to resolve was told to reinstall the visual driver for my monitor since I have an ati vid card since with the updated kernal u have to reinstall those drivers(didn't know that, I'm new to opensuse). I thought I did that before so I completely uninstalled it so I could then do a fresh reinstall but I wasn't paying attention and my laptop was unplugged for a while. I stepped away while the install was going on and my laptop died.
I tried plugging it in but had to restart my laptop when I did I got the command line rows and when I tried to start GDM it wouldn't start, I did so as SU. Attempted to connect to the internet via networkmanager and couldn't get wifi or wired to work. Anyway I can access my desktop visually just so I can start yast and install the driver or will I have to reinstall 11.2 or use the cd to repair? If so how do I use the cd to repair?

I have a DSL internet connection. The DSL is just a cable that comes into my house, no routers under my control. For a long time the internet functioned fine in Ubuntu using the default Network Manager. Recently however, my ISP was bought by another ISP, and the service name had to be changed in the DSL settings. In Windows, it connects without any issue whatsoever, only the service name change was required... But in Ubuntu, the first time I connect I get a "Apache: Not Found" page, the next time, I get to the previous ISP's login page, it continues like this for some time until I get it working. I have to try connecting it again and again.
When I asked the customer service, they said that because of the takeover, they have switched servers. But they said, it should work properly in Windows, and they were clueless about Ubuntu. Is there anything I can do to solve this issue?

I'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.

I remember that I did configure my desktop PC for wired and wireless connections since openSUSE 11.2, 11.3 and 11.4. Currently I have openSUSE11.4 x86_64 KDE. Today I happen to notice that the icon for NetworkManager in the taskbar has been replaced with a red X. I discovered that Network Manager only shows VPN tab, whereas Wired and Wireless tabs are greyed out. The strange thing is I still have Internet connection with the CAT5 cable being plugged in. I can still configure wired and wireless connections via YAST but I cannot fix Network Manager settings.

I need to share internet connection through wired-ethernet with another computer which does not have a wifi card.
However, no eth* interface shows up on ifconfig. Even more surprinsingly, neither lshw nor lspci shows anything related to wired ethernet controller/adapter:
Code: Select alllshw -C network
*-network

product: WiFi Link 5100
vendor: Intel Corporation
physical id: 0

logical name: wlan2

Why isn't my laptop's wired ethernet not showing? I have a Toshiba Satellite PSAG8U-04001W.
The installation of Debian wasn't originally on this system: it was on an older laptop whose motherboard fried, so I rescued the hard drive as well as the Debian installation. However, I doubt this should have anything to do with lspci not even detecting the wired eth controller.

I recently installed Vortexbox, which includes fedora release 14.Got everything working, but could not access the network. After a bit of searching, found that "ifup eth0" activated the interface.To do this on boot, I have added this command, together with my "mount /dev/..." command in file /etc/rc.localIt works OK, but I cant help thinking there's a proper way of doing this?

I want my netbook to connect automatically to both the office wired/static network and to the usual wired/DHCP networks.
wicd is wicked but netsearching hasn't revealed how to configure it for both wired/static and wired/DHCP except by manually switching profiles.
wicd's profiles can use pre/post(dis)connect scripts but I don't know how to integrate them into wicd when they are upping/downing connections on cable (un)plugging.
If it is not practical to solve this within wicd, I'll explore standalone scripts to configure eth0 on cable (un)plugging, as detected by ifplugd.

I recently installed ubuntu 10.10 on my Acer Aspire laptop 5745G-7671 laptop. It has an Nvidia Geforce gt 420m dedicated card, and an Intel HD integrated GPU. The problem is, I recenly installed a driver for it (because ubuntu had already found a driver in hardware management). After I did that, everytime I try to start ubuntu, I can no longer see any GUI interface.I have tried everything. I tried restarting X (which doesn't seem to work in Ubuntu 10.10, and tried holding CTRL+ALT+F7 too, but it just displays a few "[ OK ]" messages.

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?

I've had my PC connected to my router since I installed Ubuntu. My router has the address and name password for my ISP. I'd like to plug my PC directly into my ISP line, but the network manager won't find the connection, and I don't know how to tell my PC my ISP's address and the name and password to logon with. I set up my router, and I know how to make the connection in XP, but I don't know how to in Linux. I have very limited Terminal experience.
