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
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
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)

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
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?
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
I'm running Linux Mint 10 . I have a wireless PCMCIA card (Linksys WPC 11 ver.3) that I've put into master mode, and I'm trying to set up my laptop as a wireless hotspot. I am very confident that I want to do this and have no interest in using a wireless router....I say that because that topic inevitably comes up with posts like this. The problem I'm having is I don't understand how to get wlan0 and eth0 to "talk" to each other...That is, I don't know how to set it up so that traffic from wlan0 goes through eth0, so that devices that connect to my hotspot can access the internet.I've seen a few guides about this, but they were either much broader in scope (i.e. much more complex), or for other distributions, etc, and it's too much for me to follow as a linux .
I would like to pose is very specific to a system I'm assembling. I have ask for assistance from other forums and people, however the answers receive were too vague to implement.
As for my background, I am a network user able to write TCP Linux client/server applications quite easily. At a Linux system level I do not understand the necessary combination of applications and services to affect the following;
- WiFi access point/router with four ethernet ports
- Laptop (user computer) cabled directly into the access point via a physical cable
- Second computer running Ubuntu 10.04, with one WiFi (wlan0) and one ethernet (eth0) interface. Eth0 is configured as a DHCP server with the following;
IPaddress 192.168.252.1 broadcast 255.255.255.0
Eth0 is physically connected to an IP camera via a Cross-over cable. The camera is configured as a DHCP client. This connection works perfectly from the Linux box with a KVM attached.
Wlan0 is connected wirelessly to the access point and the Laptop can access the Linux box and vice versa.
My objective is to have the
- Laptop via the access point/router connect directly to the IP camera on the Linux box via the wireless link.
- I would prefer not to make any configuration or routing changes/entries on the access point/router.
The type of response I'm looking for;
- is this possible at a macro level
- what facilities/server are required on the Linux box (I would like all configuration applied to this computer only)
- what commands need to be executed and in what order. If possible a brief explanation of why the command is needed and where it fits in the grand scheme of the solution.
This is probably a gigantic request outside what the forum usual activity.
I am trying to get a network bridge configured but every time I make the changes and restart networking (or reboot) eth0 appears to come up OK but I can no longer talk to the outside world via it. With no bridge defined, I can talk to the web using either wireless or wired; wicd is configured to switch to a wired connection when available (got rid of Network Manager. It didn't recognise eth0(!)).
I want to use the bridge so virtual machines (LXC containers) can talk to the web when the machine is wired to the wireless router. Eth0 gets its IP address (192.168.1.4) via DHCP from the router and I want to bridge to another subnet, 192.168.154.n say, and the containers will have fixed IP addresses 192.168.154.101, 102, 103 etc.
I have a Gateway laptop running ubuntu 10.04, and just now have a compaq desktop running windows 7, my laptop has wireless internet connection, it's the only way that i can get it in my room. my desktop has only ethernet plugin. My question is, If i plug my laptop up to my desktop using an ethernet cable, can i bridge that connection to get internet from my laptop(using the wireless) to my desktop(using the cable)
I have an openvpn bridge up and running (ubuntu to ubuntu, both in vmware fusion machines on macs). My problem is that I cannot get a connection faster than ~9mbps even though 20+mbps is available. I've been troubleshooting for a while and have tried many fixes. I just now did ethtool tap0 and I think maybe I found it. It says the link is 10mbps. I tried to change it with: sudo ethtool -s tap0 speed 100 but it says ethtool cant change speed on tap0. How can i define the link speed of tap0?
I want to connect my dataone broadband connection in bridge mode in fedora 7. As i am currently using a bridge connection through this modem (smartAX MT882) in win XP, i want a bridge connection in fedora 7 too to access the internet from linux. I have gone through some forums discussing this issue. somewhere i have found the option "adsl - setup" and tried it in my fedora 7. But it is showing the message "adsl- command not found" on this issue. I need a detail step by step procedure for brigde connection using datone in fedora 7.
I can connect to the wireless at my school, but the connection drops frequently and regularly. Network Manager still shows bars indicating the network strength and shows that it's connected to the network in the dropdown. Selecting the network again causes it to indicate that it disconnects and reconnects. At this point I have wireless until the connection drops again. Possibly relevant details: This is the Purdue PAL2.0 network, which can be tricky to connect to, particularly for Linux users. It's a hidden network using WPA2 and PEAP. My computer is a Dell Inspiron 1420n laptop, circa August 2007.
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.
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.
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"
I'm running Slackware-13.1 on my laptop. Connection to my network is via wlan0, a cable in most cases not pluged in.When starting the system the first attempt to configure the network is via eth0, which ends with dhcpcd timing out since there is no cable pluged in. Afterwards wlan0 is set up properly.
I have installed ifplugd, which is a daemon who connects to ethernet only if a cable is connected. With Gentoo this works out of the box. With Slackware ifplugd is started after rc.inet1 (probably). So the the system still tries to connect via ethernet before connecting to the wireless network.
I have also installed wicd.How can I manage that wlan0 is prefered over eth0?I noticed that neither wicd nor ifplugd belong to the default full installation of Slackware and therefore assume, there must be a solution which meets my requirements without even one of both programs.The laptop is only used at home. Wireless connection is normaly used. I need eth0 only in a case of emergency.
the PC just hangs for ever. No mouse movement, ctrl-alt-del, nothing.
I have downloaded a Linux driver from Realtek but it will not compile. I have the latest kernel-devel, headers, and gcc. I can post compiler errors if anybody would like. They're all apparently to do with missing parameters.
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.
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
Ignoring unknown interface eth0=eth0.
ifconfig tells me
eth0 Link encap:Ethernet HWaddr 00:25:64:e8:18:2c inet addr:192.168.0.112 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::225:64ff:fee8:182c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
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.
