Debian Configuration :: How To Get /etc/network/interfaces To See Usb Wifi

Jun 16, 2010

I have a netgear wg111t that is running with ndiswrapper. It has an atheros chipset, but calling it ath0 didn't work.

Heres /etc/network/interface :

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface auto lo

iface lo inet loopback

Debian Configuration :: /etc/network/interfaces: Ra0 Or Wlan0?

Mar 30, 2010

I had one of those random system deaths, so reinstalled squeeze (daily netinst image I think...) on my eee 1000, which uses an rt2860 wireless chip. The new install only installed 2.6.32, which I had been avoiding using because of a few problems, including it dealing with networking slightly differently. I couldn't get it to work - even without encryption - using wicd. Having had a read of [URL]... , I had a look at /etc/network/interfaces, which read; This file describes the network interfaces available on your system and how to activate them. For more information, see interfaces(5).

[code]...

ra0 is now called wlan0, as far as I'm aware. I've read in several places that it is best to expunge this file of all references to wifi, so I removed the bottom section (after '# The primary network interface'). I still got nothing. However, if I go ahead and change the 'ra0's to 'wlan0's, it seems to work - wicd connects. Not very familiar with Debian (spent more time on SUSE. Drop your tomatoes - I like it. Any idea what is happening? Is what I'm doing wrong? Conversely, is the file wrong? Should it be reported? Against which package? Including any particular files?

Debian Configuration :: Multiple Network Interfaces With VirtualBox?

Mar 29, 2010

I have a rather urgent problem with my network, I got two virtual network interfaces one internal and one external. The problem is; I can't get connection to internet. The external NIC is set as a NAT and the internal is... internal.

/etc/network/interfaces
auto eth1
iface eth1 inet static
address 192.168.1.200
netmask 255.255.255.0

Running with this configuration makes my internet connect go away, however if I remove the configuration for eth1 everything is working fine.

Debian Configuration :: Network / Interfaces Allow-hotplug And Auto?

Jan 10, 2011

I was just wondering if there's any point having both auto and allow-hotplug against the same interface in network/interfaces as allow-hotplug seems to bring an interface up at boot on its own.

Debian Configuration :: Ifconfig Wasn't Displaying The Same Information That Resides In /etc/network/interfaces File

Aug 14, 2011

i recently started sockets programming. In the process i began to look for relevant network information about my computer and realized that ifconfig wasn't displaying the same information that resides in my /etc/network/interfaces file. On the interfaces file my IP address is 192.168.1.109 for interface eth0 but ifconfig displays 192.168.1.101. I was under the impression that ifconfig got its information from the interfaces file but clearly doesn't. I tried re configuring the device with ifconfig and then disabling and re enabling the device with ifdown and ifup so that the device updated its information but it didn't.

Debian Configuration :: Wheezy - Detect Printer On One WiFi Network But Not Other

Sep 21, 2015

I use a 'wifi hotspot' provided by my mobile (android) phone for internet/email and to connect to my wifi capable HP p1102w printer. Installation and use of the printer worked perfectly until I bought a new phone, again android with 'wifi hotspot' capability. The wifi connection on my new phone works fine for internet and email but it totally fails to detect my printer.

I have tried to detect and connect to the printer using system-config-printer and using the HP utility hp-setup. Both fail to detect the printer on the 'new' wifi network.

The old network connection which detects the printer as expected gives the following output:

Code: Select allpat@debian:~$ ifconfig
eth0      Link encap:Ethernet  HWaddr 6c:3b:e5:91:ec:0c 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

[Code] ....

The new (problematic) network connection which fails to detect the printer gives the following output:

Code: Select allpat@debian:~$ ifconfig
eth0      Link encap:Ethernet  HWaddr 6c:3b:e5:91:ec:0c

Debian Configuration :: Broadcom BCM4328 Cannot Find Wifi Network

Feb 7, 2010

I'm installing Squeeze on on a Dell Latitude D830 laptop with a Broadcom BCM4328 wireless network card, and I'm stuck on getting wireless internet to work. I have the 2.6.32-trunk-686-bigmem kernel. I run KDE and I have knetworkmanager installed to sort the network connections out. Unfortunately, knetworkmanager cannot find any wireless networks for eth2 (the wireless adapter). There is a wireless network, as other equipment can still connect to it.

I've installed the broadcom-sta drivers according to http://wiki.debian.org/wl. When I run iwconfig, I receive the following output: eth2 IEEEE 802.11abgn ESSID:"" Mode:Managed Frequency: 2.412 GHz Access Point: Not-Associated Bit Rate: 14 Mb/s Tx-Power:off Retry min limit: 7 RTS thr:off Fragment thr:off Power ManagementMode: All packages received Link Quality=5/5 Signal level=0 dBm Noise Level=0 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 missed beacon:0

Debian Configuration :: WiFi Connection Stuck At (Setting Network Address)

Oct 9, 2015

I have Debian 8.2 with KDE 4.14 and everything runs perfect, except for the internet connection. This problem happens randomly when I turn on my machine. Sometimes when the desktop loads, the connection is already settled.

But sometimes when the desktop loads, the wifi icon is still loading and keeps stuck at "setting network address". Since this problem happens randomly I really don't know what is happening here. My wifi chip is this:

Code: Select all01:00.0 Network controller: Intel Corporation Centrino Wireless-N 130 (rev 34)

This is the problem:

I installed Debian with non-free firmware because of this chip.

Networking :: Make A Network Interfaces Configuration Immutable?

Mar 24, 2011

Similar to the linux command "chattr +i filename", I would sure like to set my eth0 interface immutable. so once I assign the eth0 interface's IP and gateway, make it stay set until I say otherwise.

this way, I can run dhclient or Networkmanager on another interface without having to fret that it may alter this interface. is there something out there that can do this?

Debian Configuration :: How To Modify Traffic Between Two Interfaces In Linux

Aug 8, 2015

I have a laptop connected to internet via wlan0. I also have eth0 interface and with it I share internet. I want to modify/filter all the traffic passing by the first laptop, something like this:

Code: Select all                    *---------------------------*
                    |        LAPTOP 1           |      *--------------* ?
                    |-----*    *------*    *----*      |              |
    INTERNET<------>|wlan0|<-->|MY_APP|<-->|eth0|<---->|ANOTHER LAPTOP|
                    |-----*    *------*    *----|      |              |
                    *---------------------------*      *--------------*

I know that in FreeBSD it is possible to use ipfw for that purpose, because it build-in into kernel. We set for example rule Code: Select allipfw add divert 2000 ip from any to 1.0.1.1

and we can use our own application to process those packets, reinject them forward etc. It will work also fast, because as I said, it build into kernel.

Is there any standart Linux-based solution to do the same? I found some info about netmap-ipfw. Is this a correct solution? Or I have to use for example IP-aliases and iptables to do that?

I need to process all the IP-packets, not only TCP/UDP/etc-protocol. Solution also must be very fast.

Debian Configuration :: Bringing Up Wireless Interfaces At Boot Also

May 11, 2010

My new Squeeze machine detects all of my hardware including the LAN and WLAN cards, but only brings up the LAN card. There isn't even an entry for it in /etc/network/interfaces for me to modify. I tried adding the info manually but then the entire network wouldn't start. I had it configured as a static IP and I know the commands were correct due to them working on the LAN card. I believe that the name "wlan0" was causing the problem, but how else can I bring it up at boot?

Debian :: Still Can't Reload Network Interfaces?

Mar 24, 2011

So I've always asked this in the past when I get on a Debian system. This makes no sense to me but I just don't see how I restart network interfaces (i.e. eth0) on a standard Debian install. If I change the static I.P. address listed in /etc/network/interfaces from x.x.x.100 to x.x.x.101, I then assume I can simply do any of the following:

- /etc/init.d/networking stop | start
- ifdown eth0
- ifup eth0
- service networking stop
- service networking start

All the commands above do nothing. My only solution I know that works and implements the changes I've made is a complete system reboot which to me in Linux, is ridiculous. I've struggled with this over and over and nothing I do correctly assigns the new I.P. in the 'interfaces' file to the actual adapter. This isn't my single isolated Debian machine but every Debian machine I can get my hands on. Servers, workstations, VM's, any release, etc etc etc. Below is my interfaces configuration file:

Code:
auto lo
iface lo inet loopback

Debian Configuration :: How To Connect Wifi From CLI

Jan 7, 2014

I did a netinstall earlier today (latest version, amd64) on my Dell XPS laptop and ended up with a minimal installation because I couldn't connect to the internet. Now I'm trying to get online without a desktop environment.

I have an Intel Centrino 1030, so I downloaded and installed the firmware [URL].... with a usb, then rebooted. My searches have turned up a lot of instructions involving a utility called iwconfig and wpasuppliant, but these are apparently not installed. I don't really know much about it, but my /etc/network/interfaces file looks rather empty:

Code: Select all# The loopback interface
 auto lo
 iface lo inet loopback

Shouldn't there be something like wlan0 there? The network card does show up with lspci

Debian Installation :: 7.4 - WiFi Configuration Fails

Apr 8, 2014

I've been installing multiple versions of ubunutu over years and now I better understand why I faced always problems with wifi configuration on these different baselines : Debian root of course.

Now on Debian 7.4 :
The Broadcom BCM4313 driver is not loaded by default (not free product) for my wifi card. This is stated thru the UNCLAIMED declaration

Code: Select all 
sudo lshw -c network
 *-network UNCLAIMED
       description: Network controller
       product: BCM4313 802.11b/g/n Wireless LAN Controller
       vendor: Broadcom Corporation
       physical id: 0

[Code] ...

Unclaimed means : no driver found (no kernel association)

So I installed the driver located in the non-free backports by adding this target into the repository

Code: Select alldeb http://http.debian.net/debian/ wheezy main contrib non-free

and install :

Code: Select allsudo apt-get update && apt-get install firmware-brcm80211
sudo modprobe brcm80211

Check seems OK :

Code: Select allsudo lshw -c network

  *-network
       description: Wireless interface
       product: BCM4313 802.11b/g/n Wireless LAN Controller
       vendor: Broadcom Corporation
       physical id: 0

[Code] ....

I can't connect with wlan0, it doesn't work. I found information here regarding WPA2/PSK wifi configuration on debian : [URL] ....

so I added this setup to my interfaces file an got :

Code: Select allauto lo
iface lo inet loopback

allow-hotplug wlan0
iface wlan0 inet dhcp
 wpa-ssid Hznteam-Datacenter
 # hexadecimal psk is encoded from a plaintext passphrase
 wpa-psk 12345678901234567890123456

It's worth ! no more wifi network are detected and ifconfig gives no ip address allocated :

Code: Select allwlan0     Link encap:Ethernet  HWaddr 78:e4:00:4e:49:a3 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

Debian Configuration :: WiFi Not Working On HP Omen 15

Apr 17, 2016

I am new to linux and decided to use Debian. I installed it on my laptop and have a few problems.First one is my WIFI.

Laptop type: HP Omen 15
Wifi adapter: Intel Wireless 7260n
rfkill list output:0: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
So wifi is not displaying
Kernel: 3.16.0-4-amd64
Debian version: 8.4
gui: LXDE
URL....

But they see in rfkill list the adapter.How to make this adapter work?I did this with no result:

nano /etc/modprobe.d/blacklist.conf
in file add:
#Fixing a bug that prevents wifi from working on HP Omen
blacklist acer_wmi

I would like to learn more about Linux, but before experimenting I need a working system. The plan for me is to run this as my native machine with vms on top of it with other OS.

Debian Configuration :: Roaming Wifi Without Managing App

# The primary network interface allow-hotplug eth0iface eth0 inet dhcp
# Wireless Setup auto wlan0 iface wlan0 inet dhcp wireless-essid linksysn

wireless automatically connects to my home wireless network (linksysn). But suppose I wanted to take this laptop to the coffee house where they have free wifi. I am assuming that my wireless will not automatically connect to any other wifi hotspot except linksysn. So how do i set it up to roam like NM did?
