I have a weird problem with my /etc/network/interfaces configuration. I have the most simple static setup possible: Code: # cat /etc/network/interfaces

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 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

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.
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.

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?
What is the maximum number of virtual network interfaces possible?I would like to create around 300 or so. This is needed to simulate a 300 node network.

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.

If I try to add a new interface (eth1) to /etc/network/interfaces, I get

Using Fedora 10, can anyone tell me how to setup the network scripts to create two network interfaces for vlan x and y. Both interfaces should obtain an ip from dhcp and both interfaces should run over eth0.
View 2 Replies View RelatedI've not found how to configure more than one ip address with network manager.Nor with kde nor with plasmoid network manager.I need several virtual ip addresses for eth0 when the "default" of eth0 is connected i.e. "Connected to Auto eth0" should initialize the virtual interfaces.I have not found no even how to configure the ip address.I think this will be used from ifup config in yast or not?There I have the virtual interfaces but they are not taken from network manager.And last but no least: Is it possible that when using network manager the eth0 is enabled even no user has logged in?

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.
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?

I don't see the eth0 or eth1 interfaces, but I am able to see them in the Network Tools application. How do I configure the eth0 and eth1 from command line?
On my desktop having a NIC 3Com, connected to the company intranet and correctly working, I have added a second NIC ( Realtek RTL-8139) to connect a second small network ( three devices, instrumentation) using static addressing.The new board seems to be rekognized by Ubuntu, indicating "auto eth1" in the Network connections dialog. When I try to configure the connection, the "Apply" button is always disabled, therefore I cannot activate it. The command lspci shows that the board has been recognized but when i sent the
lshw -c network
the response is:

I have a weird issue that I have not seen on any forum. My jaunty on DELL studio laptop seems connected to net, but I can not access any network service (ssh, firefox etc.). But when I connect a cable the cable lights blink as it should be and in wireless connection my wifi light blinks.
It was working 2 days ago without problem, and I have not done big changes recently.I removed and reinstalled network-manager and network-manager-gnome. Nothing changed. I see a message in each restart as follows (when Openafs is starting). I can reproduce it with "/etc/init.d/openafs-client restart"

I am currently trying to set up two network interfaces in my laptop. The wireless connection wlan0 works fine and it's the one that I use to connect the internet. It's in the range of 192.168.0.x/24 (gateway: 192.168.0.1). The wired interface eth0 is connect to another router (gateway: 10.0.0.13 with IPs in the range of 10.0.0.x/24. The router is set up to work as an AP and the 10.0.0.x network will only be used to control a robot, so no internet access will be required in this network. The problem is that when I have both connections up, I can't access the Internet anymore. I can still ping both routers, I can enter both routers configuration pages but I can't connect to the Internet. If I unplug the network cable, Internet gets accessible again.
I'm still a novice in linux and I can't figure out how to fix this. I don't want to get into static ip for the wireless connection since I'm constantly using the laptop in different places. The objective is to use the 10.0.0.x router to have a development platform for the robot that can be used anywhere without having to reconfigure the robot for a new network, which is a real pain.
In detail, the laptop connects via wireless to the network with intenet (192.168.0.x) and also connects via cable to another wireless router(10.0.0.x). The wireless connection of the second router is used to connect to the robot. Since I can ping both routers when they're both connected, I think it may be something related to the ip routes. I'm using Ubuntu 9.10 with kernel 2.6.31-17-generic

I accidentally killed the dhclient processes. I am unable to access the Internet wirelessly or with Ethernet. It's a little irritating because now I have to post this using my phone. I'm looking for a way to reformat the network files to how they looked when I first installed ubuntu. I don't know quite what these are, or really anything about it.
The /etc/network/interfaces file has the following information:
I'm pretty sure there's supposed to be more.
iwconfig typed into the terminal gives me this:
According to lshw, the logical name for my Ethernet interface is eth1. I think it used to be eth0. It's an 88E8055 PCI-E Gigabit Ethernet Controller.
The wireless interface has logical name wlan1. I think this used to be wlan0. It's a PRO/Wireless 3945ABG [Golan] Network Connection. The driver is iwl3945 - [phy0]
I'm trying to configure OpenSuSE 11.2 with Open vSwitch, and I'm having trouble getting various interfaces to come up automatically when I have bootmode set to "none." startmode is set to auto (or on - tried both), and bootmode set to none, with no IP address assigned in the file. At boot time, I get the message that it's bringing up eth0, for example, but when I log in and check, the interface is not up. Also, if I try "ifup eth0", I get the following output:
xen-users:~ # ifup eth0
eth0 device: Intel Corporation 82566DM-2 Gigabit Network Connection (rev 02)
but the interface is not brought up. why SuSE is saying that it's bringing up the interface successfully, but is actually not bringing it up?
DSL modem is a Speedstream 6520 router. All computers work fine via dhcp. I'm trying to setup a small server (print server, ssh & ftp servers). I understand enough of the software part of things to get it going, my problem is setting a static IP on the server box. Every time I set the IP in the /etc/network/interfaces file and reboot, I have no network connection. I can talk to the modem through the browser, but nothing beyond that, not even local computers.
/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.254.202
network 192.168.254.0
netmask 255.255.255.0
gateway 192.168.254.254
ifconfig shows the .202 address, but box can't get to the outside world, and can't ssh into the box from a computer sitting next to it. If I let it dhcp, then I can ssh into it, and have access to the internet. In the modem, I have dmz set for that address. Wan address is static. I can ssh into it if I let it do dhcp, so I know it can work that far. But if I set static ip, I might as well pull the network cable. I've been beating my head on this for over a week, and I'm lost why I can't get it to work. I even changed the dhcp range on the modem, so the .202 is not in that range. There is no dhcp client installed that I can find. I'm using WattOS beta3, which is a light distro based on 9.04. The computer is an old Dell GX150, integrated nic. I have done ifdown and ifup eth0, still no happiness. Doesn't seem like it should be that hard, but I'm stumped. DMZ should let everything pass, so don't need to mess with port forwarding and such. I know it works using dhcp.
