Quick question guys and gals: How do I get "wlan0" and "eth0" interfaces to start at startup as as well as for "dhclient" to obtain an IP address automatically for "eth0?"
View 7 RepliesIn 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.
I have three VMs (VMWare Server 2) all running Ubuntu Server 10.04. (one I asked to be a samba share from the outset, the others are blank server installs, no pre-config)
I follow the layout in the community documentation regarding setting up firewall rules through iptables. I.e. I create a file called iptables.rules and place it in /etc. I then modify the /etc/network/interfaces file to look like this:
Code:
# 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
[Code].....
However this third one I have reinstalled Ubuntu 3 times now, and every time as soon as I modify the /etc/network/interfaces file, eth0 fails to start up (is not visible in ifconfig, only the loopback adapter), and no networking works.
I have tried reducing the iptables.rules file (which is a carbon copy across all machines anyway) to a basic accept all rule, and it still doesn't like it. As soon as I remove those two extra lines in the interfaces file, the network starts up no problems and eth0 is there.
I have 3 Interfaces for a different LAN's and when I start one interface the another interfaces goes down.How can it's possible?I configure my ethernets as:
Code:
/sbin/ifconfig eth0 172.16.3.108 netmask 255.255.0.0 broadcast 172.0.255.255
/sbin/ifconfig eth1 172.16.3.109 netmask 255.255.0.0 broadcast 172.0.255.255
/sbin/ifconfig eth2 172.16.3.1110 netmask 255.255.0.0 broadcast 172.0.255.255
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 .
How can I keep 'em separated?
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 .
View 6 Replies View Relatedjust wondering if I could get a hand with bridging my eth0 and wlan0 connection. I'm using Ubuntu 11.04 if that helps at all.
View 1 Replies View RelatedI 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;
Network components;
- 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.
So far as my knowledge goes, /etc/network/interfaces is supposed to contain a list of all the available interfaces. But my /etc/network/interfaces looks like this,auto loiface lo inet loopbackBut I have a perfectly working eth0 connection. Why does not it appear here?

I see wlan0 and eth0. I want to somehow bind these two together into one device.
How would I go about doing this?
what i want to do is
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'm having a weird problem, eth0 does not start neither on bootup nor ifup...not even issuing /etc/init.d/networking restart...i will show you some info just to check

I have two network interfaces and their entries are shown as eth0 and eth1... I want to assign them static IPs which I do by
ifconfig eth0 192.168.9.245 netmask 255.255.0.0 up
ifconfig eth1 192.168.8.245 netmask 255.255.0.0 up
But I am not sure if it will ping both the interfaces if I issue a command
ping -I eth0 192.168.9.113 (machine in network)
ping -I eth1 192.168.9.113 (machine in network)
I am getting pings from eth0 but not from eth1
I have a computer with two interfaces eth0(LAN) and eth1(WAN).I have followed some guides on the internet and came up with this iptables configuration:

I'm on an embedded system that doesn't have Gnome, and I'm trying to startup networking automatically using /etc/network/interfaces. Here's what I have.

eth0 comes up just fine. wlan0 comes up, but it's unable to acquire a DHCP address. I added the following lines to /etc/rc.local, and wlan0 comes up all the way, but I'm not too crazy about this hack.

When I boot into Ubuntu with the Xfce desktop then proceed to terminal to check my IP it is always some random IP as provided via DHCP by the router. If I then go to the cmdline and type sudo /etc/init.d/networking restart then the wifi correctly connects to the router to the one static network address that I have specifically provided for it - as stated in my interfaces file. Why is this not happening on startup?
View 2 Replies View RelatedI 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).

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've been able to get a laptop on Fedora 14 (2.6.35.6-48) working with a Netgear WNA1100 Once up and running, I execute "ifconfig wlan0 up" from root, and everything connects just fine and is stable as long as I stay logged in. But, I haven't found how to do this automatically on boot.
I've tried to use NetworkManager, but I cannot figure out how to get the GUI to show up - it says its running and enabled in the Services gui, but I haven't figured out how to actually use it! I checked to see if the nm-applet is running with ps, and for the user login, I see:
I'm not sure if the "sm-disable" flag is my problem, or how to change it. I'm not even sure if NetworkManager will allow me to set things up for bootup, but that is the path I ran down...
I assume this is a fundamentally easy process to set this up on bootup, but I'm not stumbling across the method. I recall doing this kind of thing years ago when I was an engineer, and before I got my lobotomy to become a manager...
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?
Also having this problem on Ubuntu 10.04.If I do "iwlist scan" I can pick up networks on wlan0:
Code:
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.

building a box with no other interface than tcp/ip. now in case something goes wrong when changing the /etc/network/interfaces via ftp and when rebooting the system cannot bring the interface up I would like to be able to detect it and replace the interfaces file with a default one stored on the system.
View 1 Replies View RelatedWhen I try to bring up my wi-fi PCI card (ifup wlan0 or ifconfig wlan0 up) my whole PC just hangs until I power it off.
I believe I have the right drivers, but cannot see what I am doing wrong.
I'd really prefer not to go down the ndiswrapper route.
Firstly, I can see the PCI card and the driver it is using :

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.
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:

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?
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?
