Ubuntu :: Network Interface Not Visible To Programs After WiFi Upgrade(10.4)?
Jul 15, 2010
On ubuntu 10.4, I upgraded my laptop from a fluky Broadcom 4322 wireless card to a yummy Intel 5300. The system recognized the card as far as lspci and lshw were concerned, but it was disabled. I used "sudo ifconfig wlan0 up" to get it active, removed wicd and installed nmanager, and I could access the internet via web browser and mail.
The issue is that other programs (kismet, wireshark, zenmap, anything that I use at my job) do not recognize the new wlan0 interface at all. I've uninstalled completely from synaptic then reinstalled things like wireshark, but under interfaces I get nothing, not even eth0. Nothing looks askew in syslog or the relevant lshw/lspci searches. Does anyone have an idea on this? The Intel 5300 is rolling along without a hiccup so I doubt the issue is there

I heard from my friend that i could launch programs and make them use different network interface instead of default (USB0 [3g connection] instead of ETH0 [normal ADSL connection..])I tried to google for a while and ask around in IRC, no luck so far.

I have 2 laptop with opensuse 11.2. One of them is connected to the Internet through a Mobile Connection with a CDMA/EDVO modem on the usb port. I want to share the Internet connection with the other laptop through the WiFi interface of each of them. How should I proceed?

Wifi network operated perfectly with f13. Upgrading f13 to f14 did not show any problems except for networking. It seems that the wlan0-link is not ready. Consequently no network information about adresses can be obtained. Tried with network tools to activate wlan0. No reaction Tried to deactivate Networkmanager and bring network up with
service NetworkManager stop
ifconfig -a
Then
ifconfig wlan0 up
dhclient wlan0
No reaction on network. The NetworkManager icon disappears which is understandable.

I'm travelling currently so the last network i connected successfully to was my home wpa-psk network. I hadn't tried anything until i got to my accommodation that is an open network (that I'm on now on the Win7 partition on my laptop).
The network (and a similar archetypical 'linksys' open network, aswell as some protected local networks are correctly displayed in network-manager and upon selection, it happily spins around to its hearts content for a while before saying 'no chance boy'.
/var/log/syslog spills out the usual combination of wpa_supplicant and kernel messages, the most interesting of are that the kernel deauthentication reason 6 response. 6 apparently means class2FrameFromNonAuthStation...Client attempted to transfer data before it was authenticated.
Anyone seen anything like this? I've already tried going closer to the router to no avail. I don't remember seeing this any other time I've connected to a open AP, even if that AP is far away. (Signal strength for this AP is good, kismet says its around -57dBm, well above the threshold of -80dBm, and I've tried all the suggestions from the 'Related Questions' code...

After an online upgrade from f11 to f13, on rebooting the setup attempts to configure the wireless connection and fails with a not very illuminating "error configuring your network interface" notice, offering no option but to go back and try again, which of course fails again with the same error.
Wireless card is a D-link that works fine with the ath5k driver in f11.
how I can get out of this vicious cycle and proceed with booting the upgrade?

I am a competent Linux user for a little over a couple years now, having run several versions of Fedora, Mint, Xubuntu, and others for about a month before settling on The Ubuntu Netbook Remix when it was version 9.10. Loved it. Used it as long as I could until I was informed that my version could no longer be supported. So I went to 10.04, and used that for a while... but didn't know at the time that I could switch between desktop environments... and it stuck me with the classic view. This was OK, but I'm using an Asus Netbook (1005PE)... And sorely missed the Netbook UI.
So I went and upgraded to Version 10.10. Mutter was a MESS. It was so choppy and unpredictable I only used it a few times before getting frustrated and switching back to the classic compiz UI.
But I still like the idea behind the UI, so I downloaded and ran the 11.04 version live off a flash drive (I LOVE that ability!)... and Unity worked fine. I actually liked it. So I upgraded to version 11 and booted up to find that Unity is not visible.
I can log in to the classic view just fine... But logging in under Unity will display the background and provide seemingly full functionality (If I know where to click!), but I can't actually see the UI until I click an invisible button. Once I do that, the program or menu alone becomes visible, and works fine. I just can't see Unity.

I found multiple sites explaining how to add IPs to a network interface as virtual interface like eth0:0. However I can add IPs to an interface as well using the ip command: ip a a 192.168.2.2/24 dev eth0 What I want to know is how I can make this persistent on rhel/centos.

When I log into the standard netbook environment (not the one called 2D) I get a blank desktop with blank (yet active) bars across the top and on the left of the screen. Mousing over the invisible icons on the left opens empty text boxes of varying sizes showing how long the name of the application is... I can open the applications by clicking blindly on that bar. The bar across the top is also active, I can open the menues by clicking in the right corner and moving the mouse until the one I want is open.
I have tried removing and reinstalling Unity as well as installing and removing fglrx. I posted originally in the following thread until I realised the OP there was describing a very different problem:

is there any graphical interface for installing programs in linux. Like installers in windows? or it is possible only through terminal?is there experience notes how to install things in linux? after i download something i am completely lost what to do next and how to check if this version is sutable for my version of linux etc. Trying to search internet gives nothing. Also I have this problem that my resolution is too high. so fonts are to small i cannot spend time in linux because my eyes start hurting. I use GNOMEThere are resolutions like 1280 x 960 next is 1440 x 900 1440x900 is sutable for my form of monitor.But 1280 960 is for more square like monitore so if i choose this resolution it looks bad. if i choose 1440 its too little. As it is max resolution for my monitor.In windows i use resolution 1280 x 768 how can i setup that in linux. Also in driver or something it says Ati 3600 series. But i have Ati radeon HD 3730 when i try to choose different versions of ... it says cannot start x server.

I am curious of how to make a GUI interface that uses multiple programs and commands. I have found wxwidgets as the most likely candidate for making my own interface.Is this the best programming language for a beginner?

New to 10.04, not to Ubuntu. Fresh install of 10.04, recommended proprietary nVidia driver installed because text rendering in Firefox is terribly with the 'standard' non-proprietary driver.Also new to Vodafone / Huawei modems. My previous experience with a Vodafone modem (type unknown) was with 9.04 when I helped my daughter-in-law fixing her Windows computer. It worked out of the box from the live CD and she is now a happy Ubuntu user
Optimistically, I recently bought a Vodafone K3765 modem as backup for my standard internet connection. I eventually got that to work after installing the USB mode switcher. So no it works out-of-the-box experience here Problem:The network manager (I assume that is what it is called; little antenna with signal strength indicator is not visible in the panel (right top). It is there but it's only one pixel or so wide (at occasion a one pixel wide vertical line occurs at the position where it is supposed to be). So when I want to connect I have to click a number of times in the panel till I hit it and the menu shows. Once it is visible, it will stay visible till the user logs off.

I was wondering if there's any way for a laptop to be both simultaneously connected to a wireless network, while at the same time acting as an ad-hoc network with local access to serve as a wifi connection for my mobile device, which would be ssh-ing into the laptop and using local resources.

I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

I'm trying to share some folders over the network, but the shared folders are not visible on another computer. This is through double clicking my computer from the Network list in Nautilus. However, I can access the share by typing the full address(<computer name>/<share name>) in "File > Connect to Server...".Since I can't type the address manually from my blu-ray drive, I need to get the shares to show on the network. What is wrong with my settings?

I have had a bit of experience with previous distros but I am pretty much a newbie. So I setup 10.04 but I can't get my net to connect. It's working fine on Win7 (posting from it). It's a dsl connection. I use an ethernet wire to connect to the net.
I opened terminal and used the 'sudo pppoeconf' command and followed the instructions. This is how I used to get my net working on previous distros but it dosen't seem to work in 10.04. The terminal says that my connection is active but it isn't. The network manager icon isn't visible on the top panel.

I've set up Samba under Ubuntu for windows SMB file sharing (currently unauthenticated but soon to be backed off against A.D.) This is great within Windows where l folders are available as mounted in all applications but from my Ubuntu desktop and Ubuntu laptops, we can only access network folders and files from the File browsers and bookmarks one finds in the "Places" menu. Our issue is that most (but not all) dialogue boxes don't have any options for viewing non-local files and folders. i.e. when I'm in my web browser and I go to upload a file from our local network file server to an internet location, the "Open" dialogue box cannot see any of our local network locations.

Since I installed ubuntu 10.04 I dont see my eth0 card in System->Preferences->Network _connections. Everything works fine but it puzzles me. In ifconfig iI just see the eth0, networking seems to be working fine, but it keeps puzzling me. Adding theinterface is no solution: add it and it doesnt show again

I've been using my friend's wireless network, but certain programs are having issues. Pidgin are Liferea don't work, Chromium seems to be the only usable browser (Midori and IceCat get "server not found" errors), Bittorrent (Transmission/Torrent) works fine. I've tested these programs on my laptop and desktop. Network proxy settings look fine, everything is set to autodetect.

I am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.
[87.186415] Stack:
Why I am getting this messages and more importantly how do I get rid of them.
The installation is on a VM on Hyper-V.

I have a weird problem that I can't find the answer for in the forums or docs. I can see the wireless network in Network Manager, but it is grayed-out and inaccessible. Other wireless networks are white and I can click on them and connect to them (or could if I knew the password).
My work computer, an IBM ThinkPad T43 running Win 7, connects.
My personal computer, a Dell Latitude C640 running Ubuntu 10.04, sees the network as grayed-out and therefore I have no option to connect to it.
I have tried the following:Checked for hardware drivers - the system says "No proprietary drivers are in use on this system"
Verified that the network security settings are the same on both my work and personal computers: WPA2-Personal
Why can I see the network but it is disabled/grayed-out?

I am using Network Manager to connect to a VPN server so that I can access some of the computers on the local network there. When I'm connected, I have two problems: All my internet traffic goes through the VPN. My computer is no longer visible on my local network. I waste a lot of time connecting and disconnecting the VPN. Is there any way I can set up a VPN so that I am still on my local network and only requests to 172.x.x.x go through the VPN. I suspect it can be done with iptables, but all the info about iptables goes WAY over my head.
