Fedora Networking :: Open The Network Device Control To Activate It But There Is No Network Ports In Network Device Control?
Jan 7, 2010
I just added a 2 port network card to a system that is running Fedora 11, but it is INACTIVE. I open the Network Device Control to activate it but there is no network ports in Network Device Control. It is empty.It looks like the system recognize the card and loaded correct driver.
Having trouble with wireless and FC11, eth0 is ok. When I try to activate wlan0 through system-config-network 1.5.97, I get msg: Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0... failed. This is a compaq laptop.
When i wan to activate device in network configuration, it pop out with "CANNOT ACTIVATE NETWORK DEVICE ETH0". There is a sentence after this also : "rlt8129 device eth0 does not seem to be present, delaying initialization."
I just brought up FC12 on our VSphere to begin testing..The nic did not configure properly for some reason.. I was able to go to command line, and do an "ifup ifcfg-eth0" and DHCP got an address. Go into GNOME - System-Administration - Network , or system-config-network the "Activate/Deactivate" is greyed out. Also, GNOME - System-Administration - Network Device Control show NO device..
I have my box setup as a router/NAT with two different network cards. One for external connection(connected to the Cable Modem) one for internal connection(used for internal DHCP). It works perfectly when I manually activate the two interfaces after booting(both interfaces always show up as inactive after booting), then the DHCP server and firewall. I am confused, however, by which program has control of these interfaces.
First, there is the Network Configuration (System->Administration->Network), which is where I manually start the interfaces after rebooting. Both interfaces are set to "Activate when computer starts" in here.
Second, Network Device control(System->Administration->Network Device Control), which looks to be almost the same thing as the above.
Third, the NetworkManager applet(on the top bar) - both devices show up as unmanaged when I left click on this, but if I set "Controlled by Network Manager" in the "Network configuration" window(number one above), It still does not work. Can I get rid of two of these programs, or is there some way to edit the startup scripts to start my ethernet cards before the dhcp server/firewall(which is shorewall BTW)?
The problem I'm having is on a CentOS4 machine. I don't use CentOS regularly (Ubuntu and Mint, yes) so I'm not sure if this is something that is particular to CentOS or not. I have this workstation that controls a microscope controller. The drives in this computer are some POS Seagate drives where the data storage drive has already conked out more than once. I think this time there was a problem with the OS drive that caused a lot of filesystem errors. I wasn't able to boot the OS at first but I ran fsck from a liveCD and was able to fix the (hundreds of) errors and the OS can now boot from the drive. The problem ave now is the ethernet does not work. I know there's not a problem with the ethernet controllers because I can access the internet through the liveCD. When I try to activate eth0, or eth1, I get the following error:Quote:
Cannot activate network device eth0! network-functions: line 180: ip: command not found WARNING: /lib/modules/2.6.9-89.0.9.ELsmp/modules.symbols line 1: ignoring bad line starting with 'GROUP'
I installed ZTE MF 626 modem in my F10 with kernel 22.214.171.124-170, i run usb_modeswitch and so far things happened normally. Watching through /var/log/messages it says that F10 detects two port device for this modem: ttyUSB1 and ttyUSB2, and in the sequence it disable port ttyUSB1 BUT Network Manager still set this port.I mean, when i connect via wvdial appointing to ttyUSB2 i get connection, but Network Manager fails to do it appointing to ttyUSB1. How to change device port in Network Manager?
I want to implement rate control over network interface. So I have configured Linux PC as a router with netem installed and having two interface cards.
device1----> Linux router with netem ---> device2
device1 connects to eth0 and device2 connects to eth1 of the Linux router. eth0 is configured to connect to the internet and eth1 has a static IP address on a local network. I want to limit bandwidth on devices connected to eth0.So I applied the below rules using tc and tbf.
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'm on opensuse 11.4 (11.3 won't work with my monitor).
My computer gets internet through wireless and I want to share that internet through its ethernet port. So far I've tried using Knetworkmanager to create a network bridge between my wireless and wired connections. I created a new wired connection and shared it using the ip address settings. I was able to get both connections active, but the device hooked up via ethernet had no internet connectivity.
I also tried this command: echo 1 > /proc/sys/net/ipv4/ip_forward
but another test resulted in the same fashion (no internet on wired). I believe anything I add to /proc should have an immediate effect, correct?
I have installed a new network multifunctional device Samsung CLX-3185FN using the drivers provided by the manufacturer (Samsung Unified Driver). The printing over the network works fine, I can administer the device using browser. The only problem I have is using scanner over the network. It works fine if I disable firewall, but is blocked with firewall enabled. I can not figure out which ports or port-range I must enable for this scanner. Do you have any information on this one or how can I found out the necessary ports to open?
I use CentOS for the servers I am responsible for. This time, I inherited a piece of hardware that CentOS refused to boot up on, so I installed Fedora Core 14. I have NIS and autofs working -- mostly.The home directories reside on an EMC network storage device. The problem is that when I login as a regular user, all the files under the home directory are owned by nobody/nobody, instead of user/group. I believe this has something to do with NFSv3 vs. v4, but I have yet to find the right trick to fix it.
In my YaST Network Settings (11.3), I see an entry labelled "Unknown Network Device" how to remove the confusion? The Overview tab also correctly lists my three known network devices (listed below), as does the Hardware Information utility. This is the output of lspci, and as far as I can tell, is accurate and complete. So what has YaST seen that it can't identify?
I frequently ssh into machines to do work. In some cases, the machine is headless so there is no option to log in.Under Debian and on older versions of Ubuntu I would pull out the avahi and network-manager packages and manually configure the interfaces file to my liking and be done with it.However, I would now like to learn how to work within avahi/network manager. So, is there a doc somewhere explaining how to work with modern Ubuntu networking at the command-line level? Ie: Setting up a wireless connection, setting static/dynamic IPs, etc?
I'm running Ubuntu 10.04 and all was well on my home network until a household member decided to get a laptop and jump on my network. All he does is watch videos on ....., download crap from P2P sites, and maybe even watch p0rn. Is there something I can use to control this or maybe set my router to give him the minimum resources available? Also, I want to block him from downloading junk from P2P sites or places he might get a virus. I'm on a D-Link DGL 4500 Router.
I recently purchased an eMachines e250M, and I installed Ubuntu Netbook Remix 9.04 on it, and it does not seem to be able to detect my ethernet card. When I open the Network Manager it simply says "No network devices available".I've toyed around with it a bit and looked for drivers online, but to no avail. Any suggestions for getting my wired and wireless connections working?
I am sharing files between three computers: ubuntu pc , windows xp pc and windows vista pc.( using samba ) Windows xp displays ubuntu pc correctly but vista does not,ubuntu pc is displayed as unknown device.Despite of this i connect vista and ubuntu via ip. I would like see my ubuntu pc in windows vista network.
I love Ubuntu but so far a lot of the network devices I've tried have been nothing but problems. I'm adding a second NIC to my Karmic 9.10 desktop. It's been 2 weeks and I've tried 2 other cards already with no luck. It's especially frustrating because I thought I did my homework on this one and read that it's plug and play on 9.10 here: [URL]... This is the link to where I bought it: [URL]...
I looked around the forums and tried a few things like modprobe 8139too. The card still is not working. Was that the right thing to do with this particular card?
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 have just installed Ubuntu 10.10 on a Dell Laptop. It has a Netgear WG511 (made in China) PCI wireless card but I cannot see any connections other than the wired one. Entering in lspci in the terminal mode and removing/replacing the WG511 shows (I think) that something is being detected in the PCI slot "Network Controller: Intersil Corporation ISL 3890 [Prism GT/Prism Duette]/ISL3886 [Prism Javelin/Prism Xbow] rev 01". Is this the WG511 and, if so, how do I get it to be detected as a network device?
I have made an EPSON RX500 multifunction device (printer/scanner) available over my router with the lpd protocol. Both PCs (ubuntu 10.04 laptop wireless, 8.10 desktop wired) connected to it can print, but not scan, since XSANE does not recognize the scanner over the network. It does hoverer both, scanning and printing, if connected with an USB cable. How can i configure xsane to recognize my RX500 over the network?
I am using RHEL6,and using mainbroad ethernet device PXE network install ..kernel using wireless device install automatic. I cant choose ethernet device to install RHEL6.how can I ignore wireless device when I using network installation?
