I am trying to connect my fresh new Ubuntu 10.10 to my router. However I am having a bit of difficulty. This is what I have done so far:
Code:
lspci
My devise is a Broadcom Corporation BCM4311 802.11b/g WLAN (rev 02). Then:
Code:
sudo ifconfig eth0 up
sudo iwlist eth0 scan
I get eth0 Interface doesn't support scanning.
I have only just got my first netbook and when I first installed 11.2 on it it would detect local networks and ask if I wanted to use any of them. Since they belonged to other people and I use a wired connection at home, I declined. I then took my netbook on travels and tried to connect to freely available networks there, but to my surprise it no longer detected them. I tried to go through YAsT and see what needs to be changed but no matter what I tried the wireless option was never offered again.
I have now come back and decided to get to the bottom of this. Here is what I get from iwlist scan:lo Interface doesn't support scanning eth0 Interface doesn't support scanning.It is as if there has never been a wireless capability. Can anyone advise on what to do to fix this?
I have installed open suse 11.4, gnome but no luck with wireless settings so far. kernel version is iwl3945 here is stuff that i did but it says "scan is deprecated"
linux-1f6k:/home/rajbanul # dmesg | grep firmware

The adapter I purchased (Zonet ZEW2508 ) uses the Ralink 2070 chipset - a fact that originally excited me because Ralink seems to be fairly loving to the Linux community. However, despite my best efforts I can't get the thing to work. Initially I tried following directions to set up the driver you can download from the Ralink website. The directions I found were written February first, and Ralink updated the driver February eighth - so as far as I can tell the directions no longer work. After screwing around trying to figure that out for a while I decided to give ndiswrapper a go.
Initially this seemed promising. I just harvested the drivers from the CD and followed one of the many ndiswrapper directions available - most helpful seemed initially to be the Ndiswrapper Troubleshooting Guide found in this forum, however the solutions offered there didn't work either. When I throw an ndiswrapper -l into the terminal it looks promising at first, it tells me the driver is installed and the device is present, but it just doesn't work. When I try iwconfig, or iwlist scan it tells me "no wireless extensions," and "interface doesn't support scanning" respectively. The only devices even listed are lo, eth0, and pan0. There's no wlan0 or anything of the sort.
My network name is eth2 it was changed by some reason and now i got these errors... i installed, reinstalled, re re installed, tried to run the asistant but no luck :/

If I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got

ifconfig tells me

so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
I am using an HP G60 laptop with a built in wireless NIC but am unable to get the wireless connection working. I have followed the advice in the sticky messages above and have included the information below. I know the wireless modem is working as I have got a spare USB wireless dongle running on the desktop (ironically - I can only get it working where it is not needed!!!). The same dongle will not work on the laptop. So it is a config thing and not a hardware issue On a trivial level, left clicking on the Network Manager icon shows the "enable wireless" greyed out. Desktop and laptop are running SuSE 11.3 and KDE4.4.4. I have tried the traditional method as well as knetwork manager and have no success with either. Here are the technical details.

I'm running a dual boot Ubuntu 10.04/Backtrack 4 (Ubuntu 8.10) system. I can get internet in the BT4 side but not in the Lucid side. In Lucid I can ping my router, and the network manager says I'm good to go, but I can't get to any web sites. It all started when I tried to put my laptop on another network by mimicking the settings of a computer I had just unplugged from the network. MAC address and all.
ifconfig eth0:

I booted an OS from a live CD. The OS boots successfully but eth0 fails to start. I checked lspci, it outputs these Ethernet card details:
(Broadcom Netextreme II BCM5716 GBabyte ethernet)
ifconfig -a returns only the loopback interfaces lo and sit0. The output of dmesg | grep -I 'eth' is:
"Netfront : initializing network ethernet driver"
When I run service network restart I get:
"Obtaining IP for lo [FAILED]
WARNING: Deprecated config gile /etc/modprobe.conf , all config files belong into /etc/modprobe.d/
Device eth0 does not seem to be present, delaying initialization [FAILED]"
The output of MII-tool -v is:
No MII interface found.
I was also able to find the kernel module bnx2.ko. I did insmod and lsmod lists it.
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.

View 1 Replies View RelatedI'm having trouble getting my Ubuntu 10.04 machine (Sony Vaio VGN-SR490) to connect to the Internet by way of an Ethernet cable connected directly to my router.
I'm able to connect to the Internet using this same cable using a Windows machine, so there's something wrong with the way Linux is configured.
How do I got about figuring out what the problem is and solving it?
Here are my network settings on Linux:

It looks like the network adapters list is empty. I will now install both Windows XP and Ubuntu Linux dual-boot. I'm still not able to access the internet, even through Windows. I'm wonder if this could be a hardware problem with the computer or a problem with the router itself. Other computers can connect to this same router, and work fine. (That's how I'm posting this after all!)
In an attempt to set up wireless so I could connect to the university network, which I think I probably should have just downloaded network manager or something but I didn't, I tried to put things in /etc/conf.d/net and some other places and I am afraid I'm not sure exactly what (and I have learned my lesson! I will pay attention to what I am doing so I can undo it next time I mess around with stuff!)
Anyway, the long and the short of it is now, when the computer is starting up and its doing the init stuff net.lo doesn't start. Later try and start net.lo or net.eth0 you get told "not enough arguments"
The following are the output of command "ifconfig -a":

The interface "eth0", which is down, was not displayed, but loopback interface has been displayed. So, how can I make my application display all interfaces, including the interfaces which are down, but excluding the loopback interface?
I have already tried reloading the drivers, restarting the interface (which is missing) and every other solution I found on this forum (well... not exactly all of them but many of them) uname -a gives Linux hostname 2.6.35-27-generic #48-Ubuntu SMP Tue Feb 22 20:25:46 UTC 2011 x86_64 GNU/Linux

I have two network interfaces on my computer but only one of them is connected to an Ethernet cable. Until now on every Fedora release, the activated primary interface has been named as eth0 and everything has always worked well without any problem. Recently I switched to Fedora Core 12 and surprisingly I observed that for the first time, my primary interface has been considered by the system to be eth1 instead of eth0. I tried to replace the content of ifcfg-eth0 by ifcfg-eth1, yet system gave me an error that there was MAC address mismatching. I conserved their MAC addresses in their files and just replaced other connection parameters ( such as IP ADDR, NETWORK, NETMASK, etc.) but it did't work. When I do "server network restart", the command blocks.
As I try to install oracle on this system, regarding the fact that oracle requires static network configuration on the primary network interface, I don't know how to proceed in order to set eth0 as my primary interface (or rather set the current eth1 to eth0 because it is actually eth1 that refers to my activated primary network card).Just one more time, I would like to remark, that with previous versions of the Fedora Core, on the same computer (with the very same two network cards) I never had problem and I had installed oracle on the system with success, having the statically configured eth0 correctly detected by the system.
I'm having the same Harker2010 's problem.Running 10.04 LTS on a Dell latitude D-820, and switching between lan and wifi worked OK until last upgrade.Harker2010's screenshots are also valid for my problem. I've tried everything I see on this post but the problem still there.

Is there any utility/commands available to find out the physical interface ?
I used the network manager to configure my eth0 interface.It is working fine. I have found the nameserver entries in /etc/resolv.conf files. But the /etc/network/interfaces file does not carry the ip, netmask, gateway,network and broadcast entries. It only has a entry for the lo interface. where are the settings for eth0 as done by the network manager, stored in case of ubuntu?
View 7 Replies View RelatedI have 2 network cards eth0 and eth1, for eth0 i set a manual MACADDR in network scripts. Ok so every time i boot, if the cable is plugged in, my eth0 fails to mount or i don't know.. i get this after bood when i type ifoncifg eth0 (eth0: error fetching interface information:Device not found). So i have to unplug the cable when i boot, then plug it in and do a service network restart.

Process substitution therefore fails, because bash wants to create files under /dev/fd./dev/.static/ and /dev/.udev are populated. aptitude udev shows that the Debian package is installed, even though udev cannot be supported on this Xen vps (and, I believe, isn't supported by default until later stable versions of the Linux kernel).
I can solve the immediate problem by symlinking from proc/self/fd to /dev/fd, and putting the appropriate script in init.d. But are there any risks arising from Debian being misinformed about what my vps can do? And if so, what should I do about it?

I would love to be able to use TrueCrypt consistently across all my machines, be they Windows or Linux. As it stands, I can do full-disk encryption with pre-boot authentication only on Windows.
I don't really understand why this is. Are there technical challenges specific to Linux/Mac that make full disk encryption harder? Does anyone know whether TrueCrypt will support this in the near future.
PS. yes, I'm aware that there are other options. My goal is to simplify my life here and use the one tool across all machines.
