Yesterday I did an upgrade and today my box is unable to connect to the internet.
I have tried another cable, it didn't help.
Basically NetworkManager does not connect eth0 to the network, if I try to run ifup from the command line I get:
I can see in network configuration settings, that the device has been correctly detected and eth0 interface is correctly activated, yet when I try to uncheck the box manage by NetworkManager and start it manually, it tells me that the cable is disconnected... I've tried two different cables, different ports on my router - no help.
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.
Newbie Question: How do I setup networking on openSuSE 11.4 on an HP Proliant DL385 G7 with 4 NICs to host Windows 2008 R2 on Xen? I've installed openSuSE 11.4 with all the patches (and most of the server patterns - Mail and News, LAMP, LDAP, Samba, etc.), and I've installed Windows 2008 R2 in a Xen virtual machine. I'm having problems configuring the 4 NICs eth0, eth1, eth2, eth3 are "bound" without an ip_address as br0
eth0 connects to my ISP - currently through a private LAN - It connects directly to the router with static IP 192.168.0.105 Eventually, one of the other NICs will serve ip_addresses via DHCP to a separate LAN (for use in an office setting), and eth0 will be set with a static IP from the ISP That means, eth0 will be static to the ISP, and the other NICs will attach to a switch serving private ip_addresses in the 192.168.0.xxx range.
Currently, I have br0 unconfigured and eth0 static. I have configured eth0 in the External Zone and br0 in the Internal Zone in the firewall, and all the correct ports are opened (afaik) I have enabled masquerading. Hostname, Domain (workgroup), DNS Server addresses and IPv4 Gateway are configured.
Windows 2008 R2 (Guest VM in Xen) "sees" the other machines on the network, and "browses" the internet, although it will not download patches except intermittently. I have not tried connecting to it from the LAN Eventually, I wish to run Windows Terminal Server. openSuSE cannot "browse" the internet, though it initially did. What am I missing? I "think" I need routing or NAT, or I may have my bridge setup incorrectly, although I've tried almost every combination. Google says Xen should be setup with either NAT or a Bridged Network.
The card is recognized by System--admin--network as the correct card (BCM43XG) and assigned eth1. However, NetworkManager shows no wireless network. I have a great signal on the same machine if I boot into a Windows partition.
I'm on F14 and can't seem to get NetworkManager to behave. I seem to remember being able to start my machine and see my static address configured right after boot. For some reason, that's no longer the case. When I finish a boot, I'm not getting any address until I log in. I've tried editing the ifcfg-eth0 both by hand and by the system-config-network. I've played with the "Available to all users" checkbox on both the nm config applet as well as the system-config-network gui. I can't seem to get it to behave predictably and give me my static without having to be in a gnome session.
Here's my ifcfg-eth0 from /etc/sysconfig/network-scripts
I have virtual box installed which automatically installed bridges for my network adapters. This has always worked fine. I'm attempting to set up a static IP for this machine now. I use NetworkManager, and the physical connection (eth0) is set to static IP of 0.0.0.0, and the bridge (br0) attached to eth0 was set to DHCP. I changed br0 to my desired static IP and lost net connectivity (I'm talking about the host, not the virtual machine - I'll get the host working first). Re-enabling DHCP restores connectivity. So I don't know what the problem is, but I am unable to assign a static IP to the bridged connection. Do I have to do this differently? Do I need to remove the bridge so I am using just eth0 again, assign the static IP to eth0, and then re-install the bridge? I haven't tried that yet because a) I don't know how to remove & reinstall the bridge, because it was done automatically by Virtual Box installation, and b) I could probably do that if I had the time figure it out but right now I don't.
I set up a static IP on wlan0 on another machine using Network Manager and it works fine. That machine also has Virtual Box installed but for some reason doesn't have the bridged connections. (Perhaps because it runs Ubuntu, not OpenSUSE, if that makes any difference)
Just purchased a Asus USB-N13, and having follwed a mixture of tutorials, including the readme on the driver disk, i have had no luck in getting this adapter to work.Upon using "sudo iwlist ra0 scan" the adapter can see multiple networks, however device manager is stating that the device is not managed. How can I get this sorted and connect to a network?
After the use of pppoeconf, the network manager does not recognise neither the wired nor the wireless connection anymore. (It nicely did it before that) I tried to replace the etc/network manager folder with that of a different machine. Still the same. What else can I do to reset Network Manager ?
I'm having trouble getting onto the internet with ubuntu 9.04. I have just moved house and have just got the internet set up here (typing this on windows laptop with wireless). My ubuntu desktop is plugged in to the network, but in the top right hand corner when I click on the network icon I get: "Wired network device not managed"
In my old house I had a static IP. Is this anything to do with it?
I use my T61 both wireless and in the dock, where I switch to the wired connection. After the latest round of updates, I seem to have lost the ability to switch to the wired network. When I turn the laptop on, I see it connect to the wireless network, but when I left click on the tray icon under Wired Network is says Device not managed. I have not made any changes to anything in the last couple weeks, besides some updates. How do I go about getting the wired network back in there?I tried to add eth0 back into System - Preferences - Network Connections, but whenever I try and add eth0, but it still says Device not managed.
I need to setup an Ubuntu Server to handle backups over the network (probably rsync over ssh). That server will then transfer the backup data offsite over a secondary external data line.How can I configure the ethernet interfaces to handle such a scenario?
I installed the driver for my network card. iwconfig and ifconfig are all responsive to connecting to the network, I'm given an access point address. Then, I try to connect to a website and no dice. ping www.google.com yields no result. What gives?
Ubuntu desktop 9.04 Whenever I try to copy files to any machine on the network, the transfer stops and I no longer have access to the network or the internet. This happens whether I'm doing scp, copy with the gui, when copying to windows machines, and when uploading database files with phpmyadmin. I have been able to successfully transfer large amounts of data outside of the network via ftp, but not to any on the network. I've discovered that I can re-enable network access by restarting NetworkManager.
I'm also new with linux i tried ubuntu and mandriva, and they worked fine out of the box.But I wanted to try Fedora because it looks great to my opinion.After installing it, everything worked fine, so I updated the system, and after the update my internet doesn't connect anymore, but it does see my wlan ssid. but it just keeps on asking my wpa key.... everytime.
Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?
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 a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
I have somehow made 2 internet connections on my fedora 10. one is system default, which doesn't work. so I usually login and select from the top panel to the other working one. how to choose it from a terminal? then I can do it from a remote terminal.
Suddenly, for no reason apparent to me, on initial logon I don' t have an eth0 connection. I click on the Network Manager icon in the tray, and connect that way. But it would be nice if it connected automagically. How do I fix network to connect on 1st logon?
i have no problem with DHCP Internet conection, when i set up to manual and manually imput an IP ADDRESS-NETMASK-GATEWAY y get local red but not Internet. Im i missing something, i cant find a guide for dummies.
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 just tested Networkmanager on OpenSuSE 11.2. I tried with my wired connection and it works.
I thought I test to connect with network sharing with my Android phone. The Android phone connects according to Networkmanager, but I'm not sure if it actually works as the wired connection is still active.
I tried to figure out how to disable the wired connection, but eventually gave up and just pulled the wired network plug.
But surely, there must be a way to disable connections from Networkmanager?
After an update this week I noticed some strange things with the network. 1. The network connection doesn't activate itself automaticaly. Have to do it every time when booted up. 2. At the taskbar icon the previously "Auto eth0" changed to "System eth0". I guess this is kind of connected to the first issue 3. I can't connect anymore to the windows network -Times out (also worked fine before) How to set it up to the "old" way?
I recently switched from ubuntu to fedora and had a script to mount and umount sshfs when the network changed states. I placed the scripts in /etc/network/if-up.d/ and /etc/network/if-down.d/ and they were run any time the network went up or down. The closest thing I've been able to find is editing the ifup and ifdown scripts in /etc/sysconfig/network-scripting/, but that looks like it would be broken after an update. I'd also rather not use a script with ping because that wouldn't work well when the network goes up and down several times.I've been looking for a while and haven't been able to find a method similar to debian on fedora. Is there something I overlooked?
I'm trying to share internet connection with my wifi capable mobile device. For that I'm creating ad-hoc wifi connection in networkmanager with 'shared to other computers' ipv4 option. And there is the problem - the device cannot get the setting via DHCP. The firewall is adjusted properly by NM, dnsmasq is started. I've looked at dnsmasq arguments string and found that the temporary config file which is provided by NM is empty. So, where else should I look for a possible reason or should I just post a NM bug?
