Debian Configuration :: Creating A Network Bridge From Eth0 To Wlan0
Jan 18, 2016
I am very new to linux.I have a network camera which only has an Ethernet port but no WiFi. Sadly no Ethernet port is available close to the camera.
Therefore I now bought a raspberry pi and installed raspbian to create a bridge into the wireless network, for connecting the camera to the internet.I now played around with the interface- and bridge configuration but I have problems with it.This is how my interfaces file looks like:
(The WiFi is secured with WPA2 Enterprise)
Code: Select all# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
[code]....
The WiFi is connection works fine and I am in the internet using the WiFi.But I am wondering about eth0. The network parameters I specified are not the same as the parameters ifconfig tells me.Ip, Broadcast, Mask, nothing is as specified.It would be nice to give the camera a static IP that I can access it always with the same IP from the RaspberryPi.The Raspberry Pi itself gets always a new IP from the WiFi network. How do I get the camera into the internet using the existing connection of the Pi?
I'm new to this forum site and I was wondering how can I bridge a network between the eth0 and wlan0 connections?my eth0 NIC is a RealTek RTL8111B 10/100/1000 Ethernet Card (OnBoard) and my wlan0 NIC is a RealTek RTL8187B 802.11b/g WiFi USB Adapter Card.Are there any utilities, such as bridge-utils that I can use, except for Firestarter since Firestarter states that the eth0 connection is not established, or do I right-click on the network icon and select Edit Connections and go to Auto eth0 and under the IPv4 Address setting and select Shared to other computers and run a live connection there?The main reason is that I need an Internet connection for my Xbox 360, which is connected to my Linksys WRT54G 802.11b/g Wireless Router, that has DD-WRT firmware installed and 4 WiFi hotspots for any wireless device, such as my PSP, DS, DS Lite, Wii, Laptop(s), my brother's PC (needs a WiFi card), and my dad's PC (needs either a WiFi card or an Internet connection from my brother's computer to my dad's PC)
Here are my Computer Specs: ECS nForce6m-a Motherboard 2GB DDR-800 PC6400 Memory
client <--> wlan0 <--> computer <--> eth0 <--> internet
i have 2 network connections eth0 wired connected to internet wlan0 wireless (work fine) i have installed hostapd with madwifi and so on oki when i run hostapd the clients see the hot spot oki clients connect with wpa oki network manager run at demand not automatic (keep it for internet help) now i'm a bit lost what do i need is wlan0 give the client an ip (dhcp demand) create a bridge between wlan0 and eth0 steps to create a permanent bridge between wlan0 and eth0
Internet <---> Router <---> Debian server <---> Windows PC
I want the server and PC to both have internet access, and I want to be able to forward ports from the router to the server. I know how to configure the server to give the PC internet access, but how would I assign an IP address to the server and give it internet access? I have used a very similar setup a few years ago, but I can't remember how to do this.
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?
I have two ethernet NIC's on my debian server. One built-in Realtek [eth0] (attached to internet), and a PCI Nvidia ethernet card [eth1] (attached to my Win7 netbook). I used this guide to setup the bridge: url. It worked when I was behind a router. But when I moved the computer in front of the router, to direct connect to the internet, the internet stopped functioning on any device that I plug into my Nvidia NIC. The name of my bridge is 'br0'. Does anyone know how to fix it, so I can route the internet to my second NIC?
My Win7 netbook displays this at an 'ipconfig' command: Windows IP Configuration
# 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 br0 iface lo inet loopback # Set up interfaces manually, avoiding conflicts with, e.g., network manager iface eth0 inet manual iface eth1 inet manual # Bridge setup iface br0 inet dhcp bridge_ports eth0 eth1
I have a debian squeeze box with dual NICs that I'm trying to configure with two virtual hosts. I'd like to have one of these machines act as a router for the 2nd NIC so I can plug in a switch and have a separate subnet.
Something like: - Openwrt router 192.168.1.1 (firewall/vpn/stats for 192.168.1.0/24 domain) - KVM machine with 2 NICs (192.168.1.2) - Virtual machine #1 has a fixed IP of 192.168.1.3 (virtual nic) - Virtual machine #2 has a fixed IP of 192.168.1.4 (virtual nic) but also controls the 2nd nic and routes 192.168.80.0/24
I'd like to use the 192.168.80.0/24 network for testing equipment without poisoning my existing network.
I'm attempting to use a network bridge to connect my virtual machine, like so:
[Code]...
The issue is that when I type the following command, I get the further following horrible error message that doesn't seem to really point me to anywhere and I can't seem to find any relevant information to my problem on the web:
root@darkstacks:~# qemu-system-i386 -hda test.img -m 128 -curses -net nic -net tap,ifname=tap0 warning: could not configure /dev/net/tun: no virtual network emulation
Does anyone have any idea what I need to do here? My processor does not have the vmx flag, as it's a 2.4GHz P4. I don't know if that might have something to do with it.
currently on an acer aspire 5532, and using mozilla and google chrome. webpages take about 10-12 seconds to load using the ethernet, wifi its about 2-3 seconds. using eth0 loading videos - broadcast yourself. in chrome, will sit at "resolving host" for about 10 seconds before bringing up the page. you would think eth0 is faster than wlan0, but for browsing the web its slower. i tested the speeds at speedtest.net - the global broadband speed test and both wlan0 and eth0 get the max speed my internet provides.i never downloaded drivers for the ethernet card or wifi, they worked so i didn't try to mess with them. but perhaps that is my problem?
I have installed Open SUSE in my DELL server which has 2 broadcom NIC cards, it showing both the NIC cards in Network configuration in YAST ,but it showing as not configured and not connected . Kernel device eth0,wlan0 are not present. In device manager also 2 Broadcom nic cards are detected.
I just installed Fedora 13 on a new Dell XPS desktop and some of the networking files are not created/missing. The computer has Broadcom Gigabit wired card and Asus PCE-N13 wireless card. When I type lspci, I see that Network conroller: RaLink RT2860 and Ethernet controller: Broadcom BCM57780 Gigabit Ethernet. So, somehow they are being detected by the OS, but I am not sure if the drivers are installed or why some of the network files are missng.
I've had 11.4/KDE working pretty well on dual boot Asus G73SW for a few weeks now. Only issues were the FN-* functions that control keyboard lights and whatnot but no biggie since the essential worked.The last couple of days the update notification was indicating 1,201 updates to be made. Yeah it seemed extreme but I googled around and checked the forums and there was nothing related. I figured I might be missing some packages since I installed from the live KDE CD (still 1202 updates!!!???). So I updated. Big mistake!!!!! Ever since NetworkManager cannot connect to the internet, be it wired or wireless.
Initially it could not even see my home network but it picked it up after I removed the plasmoid from the panel and reinstalled it. However it doesn't respond when I click the network icon and still no connection.I managed to get eth0 working with ifup but not wifi. The last part of network manager log file is quoted below. I can send the whole thing to whoever is interested. I can't make sense of it but maybe someone on the forums can.
Installed a TP-Link TG-3269 Gigabit card in a machine running OS 11.3 32 bit, when I go into Yast, Network Devices, Network to try configuring the card I get this errormsg: Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details. Couldn't find any mention of the card in dmesg's output, (though the 8139 onboard card is in there) there is some stuff about pci host bridge but I don't know whether they would be relevant or not
The chip on the card says it's rtl8169sc but lspci lists it as being 00:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Device 8369 (rev 10) Done some googling and there don't seem be any drivers for a Realtek 8639 and it returns no matches from a search on realtek's site, but there is a driver there for rtl8169sc chips, which I downloaded and installed, no errors when installing it Even after a reboot I still get the same error in Yast's Network Settings screen, lspci still lists it as 8369 and the device isn't listed at all if I run ifconfig
I have setup hostapd and a bridged setup with br0 bridging eth0 and wlan0. The setup works but unfortunately not on bootup. The reason is that the bridge can't add iface wlan0 because it is down for some reason at this time. When hostapd is running (after the network script) the interface is up and can be added to bridge via
From yesterday on, I am not able to connect my Laptop to my WiFi Router automatically when logging in to gnome desktop.
The following is the message found in /var/log/messages.
Its Lenny 5.0.4 and I can see my wifi LED ON till the gdm login page. After the login, while loading my desktop, the LED goes OFF and I have to restart the network-manager for enabling the wifi again. Why is this happening? Do I have to change the configuration settings in /etc/dbus-1/system.d/ to fix this. I really don't know what change needs to be done there and where.
The same day when this problem started while logging in I got an error message from nautilus. The screen-shot is attached with this mail. Does this error have anything to do with the network issue?
I've recently installed Debian. But the wireless network is not working. In Gnome it says "Device not configured" And if i try a ifup it says: root@accroft-msi:/home/accroft# ifup wlan0Internet Systems Consortium DHCP Client 4.1.1-P1Copyright 2004-2010 Internet Systems Consortium.All rights reserved.

I have got a debian (v3.16.7-ckt25-2) for server (without X). There is a br0 bridge connected to eth0 network device. It works fine when I start it manually by
Code: Select all# ifup br0 but I cannot start automatically at startup.
there was a missing line in /etc/network/interfaces:Code: Select allauto br0
I'm having problems getting my wireless network working. The same problem exists in both Debian 5.04 and Ubuntu 8.04. I'm using a Sonet ZEW2500P USB wireless card, which shows up when I look at lsusb. The card works under Windows, so its not a hardware problem.
When I run iwconfig, wlan0 simply doesn't show up on the list. It doesn't go by any other name either. I've tried adding iface wlan0 inet dhcp auto wlan0 to my /etc/network/interfaces file, but to no effect. I've tried using both the rt2000usb driver and the old rt2570 driver, and made sure both are not loaded at the same time using lsmod, but this doesn't help.
I wanted to try the CONFIG_NET_RADIO enable/rebuild kernel technique, but I can't find CONFIG_NET_RADIO anywhere in my autoconf.h file!
I assume someone will want to see a log file of some kind - just let me know which one (and where I can find it).
This is embarrassing. I can't get a wireless address from my router with dhclient. The distribution is sid/lxde/liquorix kernel with no network manager on /dev/sdb1.

I've installed firmware-iwlwifi I've modprobe -r'd and modprobed the iwlagn module I CAN scan, using iwlist wlan0 scanning, and I can see my essid, hovering in the distance. it is definitely broadcasting.
I use wicd and wicd-curses. No wireless show up in wicd-curses. ifup wlan0 gives me no dhcp offers received and slumbers again. from iwconfig:

I'm trying to bridge connections between a wired and a wireless connection in one of my computers. I was told it was impossible due to low-level limitations in the wireless subsystem, but apparently theres a way if you somehow forward packets from one port to the other. Is there a way I can achieve this?
I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.
I just switched from Fedora 13 to openSUSE 11.3 on my laptop and so far love it...well...not quite. I'm having some major network issues. As in...no networks.
I installed everything and booted up for the first time. Everything worked great, I had wireless through wlan0 and could connect directly to my home router via eth0 with no problems. Installed a few applications and ran into some problems with hibernating/suspend modes. I rebooted and like magic, NetworkManager said networking was diabled. My WiFi light was off. Network switch on the computer didn't do anything.
I thought alright, I'll connect my ethernet cord and can go from there....problem is that won't work either. I tried searching for drivers online on my desktop, found some and transferred them via USB with no luck. They won't install. I have no idea why, or whats going on but I really need my laptop for school on Monday so it would be AWESOME to have it working by then.
Here is what I have: Intel 5150 WiFi card Dell Studio XPS M1640 laptop OpenSUSE 11.3
On a new Dell Lattitude e6400, I have installed both arch and Ubuntu. Ubuntu recognized wifi and ethernet right away and connected and is working fine, but in arch, I am having more problems then I usually do when using arch. From the output of lspci the ethernet is a intel device 1502, I have researched this and found it to need the e1000e module as its driver. I modprobed this module sucessfully, but no ethernet. With wlan, i have found that the card is a DW1501 Wireless-N WLAN Half-Mini Card that has a broadcom 4727 chip in it. I downloaded the windows driver for this chip and isntalled it with ndiswrapper but this did not help. What I think is the root of the problem is the error message that restarting networking creates.
Quote:
Dell only supplies drivers for ubuntu, but it should still be possible to get this to work. I have tried booting various live distros that I had drives for and I found that the parted magic boot disk saw the ethernet port and was able to connect to ethernet, and that the ubuntu live disk was able to connect to both wifi and ethernet. Somehow they must be seeing the prescense of the hardware in a way that I have not tried with arch. Please help, I really need to get this computer workign with arch.
Is there a way to get conky to show only eth0 or wlan0? My configuration only shows the wireless bit when wifi is switched on but shows eth0 all the time.
Temperature: I have nvidia card with drivers from rpm fusion, can conky give me the temperature of the card and the cpu?
I have a wired connection going to my router, which is encrypted with WPA2-PSK. That works fine. I hooked up a WUSB54G v4 (Linksys USB Wireless Adapter), and used ndiswrapper to install the drivers from Vista to make it compatible with WPA2. Also configured the /etc/network/interfaces with the wpasupplicant lingo to make it all work. So if I do that, my eth0 will not work anymore. Also on a side note my network manager stops with displaying in the top panel. Not a problem I can run /etc/init.d/networking (re)start and dhclient eth0 (wlan0) and all the other commands that are necessary to make it work.
Back to the problem, so I hook up wlan0 with the settings and eth0 stops working. I want to use the wlan0 solely for the purpose of my media server. The eth0 is there for my internet and that is it .
I'm running Ubuntu Server 10.10 on a 64 bit laptop (also have GNOME installed just for convenience), and have a website up using apache2. I am wondering if it is possible to configure both eth0 and wlan0 to the same local static IP address? I would like to walk around my house and do stuff when I want and still have the website accessible, but also be able to jack my laptop back into the router when I am away, just for peace of mind.
Is this possible? If it is, do I need to do some configuring in apache2 to tell it to use another device? Is this even a smart way to get what I want done?
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"
