Ubuntu Networking :: Set The IP In The /etc/network/interfaces File And Reboot?

Jan 20, 2010

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.

Ubuntu Networking :: Adding Interfaces To /etc/network/interfaces?

Apr 16, 2010

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

Code:
* Reconfiguring network interfaces... SIOCSIFADDR: No such device
eth1: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device

[Code]...

How do I add 2 interfaces and get anyone of them to work, as available ?

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.

OpenSUSE Network :: Network Manager Default Connection Can Handle Virtual Interfaces?

Jun 7, 2011

I'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?

Ubuntu :: Installing The Two Network Interfaces?

Feb 26, 2010

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:

*-network:0 DISABLED
description: Ethernet interface
product: RTL-8139/8139C/8139C+

Ubuntu Networking :: ADVISEADDR: Error In Specifying Interfaces: No Existing Ip Interfaces Found

Jan 7, 2010

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"

Code:

ADVISEADDR:error in specifying interfaces: no existing ip interfaces found

#lspci

Ubuntu Networking :: Set Up Two Network Interfaces In Laptop

Jan 16, 2010

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

Ubuntu Networking :: Fixing Network Interfaces

May 27, 2011

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]

OpenSUSE Network :: Can't Get Interfaces To Come Up Without IPs

Apr 19, 2010

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?

Ubuntu Networking :: /etc/network/interfaces Not Booting On Startup?

Sep 23, 2010

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?

Ubuntu Networking :: Multiple Interfaces In Network Manager Have The Same Name

Apr 7, 2011

I have a problem where multiple interfaces in my network manager have the same name. This means that I am unable to have different settings for each interface. Here is my setup:

Ubuntu 10.04 LTS
uname -a: Linux muon 2.6.32-30-generic #59-Ubuntu SMP Tue Mar 1 21:30:21 UTC 2011 i686 GNU/Linux
Adapter 1: 02:00.0 Ethernet controller: Intel Corporation 82573E Gigabit Ethernet Controller (Copper) (rev 03)

Adapter 2: HTC Desire tethered via USB. When I start from scratch, with no remembered networks in the network manager, the Ethernet is shown as "Auto Ethernet". When I then connect the HTC Desire, the new network is shown in the network manager also as "Auto Ethernet". Previously, when I right clicked on the network manager and selected "Edit Connections", there were multiple "Auto Ethernet" entries under the wired tab.

Now (and I do not know what changed, sorry), I only see one entry. When I edit this entry (say, add a route), then the route is added for both network interfaces. This used to still work, so I was not worried about the name clash, but now it is causing problems so I need to have a different name for each network interface.

General :: Get Wvdial To Run From /etc/network/interfaces?

I am using wvdial to connect to a mobile network (I have a usb modem) and it works fine. However, I wanted to automate the connection a bit (currently I am running wvdial every time I want to connect). I was wandering if there is a way to add this network to /etc/network/interfaces (in a truly Debian way) to have it connect on startup and/or whenever I connect my modem.

General :: Set Up Routing Over Two Network Interfaces

Sep 9, 2011

I'm often on my corporate network but also need to be on another network simultaneously. At the moment I have to manually switch back and forth between the two. I'm using ubuntu 10.04. I've come across an excellent document that explains how to do this: "Linux Advanced Routing & Traffic Control HOWTO" by Bart Hubert. He mentions:

make sure that your kernel is compiled with the "IP: advanced router" and "IP: policy routing" features

I've downloaded the kernel sources, but I don't find any config options with names like these in them.

sudo apt-get build-dep --no-install-recommends linux-image-$(uname -r)
sudo apt-get source linux-image-$(uname -r)

Searching doesn't reveal anything

~/kernelBuild/linux-2.6.35/debian.master$ grep -iR policy . | grep -i routing
~/kernelBuild/linux-2.6.35/debian.master$

So my question is...how can I tell if the kernel I have has these config options. Failing that, how do I build a kernel that does support these things?

Additional use cases for this knowledge. (1) At work with desktop computer plugged into corporate network. Plug 3g phone into USB port. My corporate network wont allow me to access my external servers over ssh, but the 3g phone will. (2) At home on the corporate VPN, but would like to access my other local network computers.

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
