Ubuntu Networking :: Change Ip Address Of Second Internet Sharing Network Card?
Sep 2, 2010
I have a second network card in my ubuntu desktop that I have sharing my internet connection with a wireless router. I have set the router to a static ip address within the network cards range. But, every time I restart the computer, the network card uses a different ip address. One time it will be 10.42.43.1, the next time it will be 10.42.46.1, ect. This makes me have to hard reset my router every time it does this. How can I set the network card to use the same ip address all the time?

Im living in a student-city where we get one internet-cable in the wall each, if we need more we are told to use a switch. But, since ive got some tech that depends on wifi, I was wondering if its possible to setup my ubuntu to work like a sort of wifi-switch?
Basically, Im not allowed to set up anything that resembles a router..(so no dhcp) all i need is what a switch would do, only wireless and wpa/wep would be very nice
Atm ive got my cabled network plugged into my onboard ethernet-port, and ive got a d-link DWA-556 (Atheros AR5008 I think) wifi card that i wanted to use to share my connection. is this doable?

Regardless of distribution, but not Windows, there would be this a/v computer that has a sound card and video card for which any other Linux computer would have access to these two devices. How do I achieve this mess?
I was primarily thinking of having a share on the a/v computer that would expose links to the sound card and video card for which the other computers could simply link to these devices. Does this sound kosher besides the conflict of concurrency?

I used network manager to share internet connection coming to wlan0 with eth1.
I have internet in my PC coming to wlan0 and I want the client I hook to eth1 to have internet too.
It works with network manager but I think it added something I didn't ask for... Apparently the client connecting to eth1 is recieving an IP from a DHCP server outside the range of wlan0 IPs.
How can I configure eth1 to assign an IP that is inside my wlan0 LAN or at least give a static address to eth1 client that's inside my wlan0 LAN and internet keeps functionning.

I've got access to my LAN and the Internet via my wired ethernet connection. I'd like to share that access with my iPod Touch (device shouldn't really matter) via an Ad-hoc wi-fi network.
This tutorial in the docs seems to describe the right setup but is very out of date (7.04). Instead I found this tutorial and followed it to create the Ad-hoc wireless network. I was able to connect my touch to the resulting ad-hoc network without a problem, but I didn't have LAN/Internet access.What's the next step to get the clients on the ad-hoc network out to the Internet?I found this page in the docs that says I'd need to install dnsmasq-base and uninstalling dnsmasq. I checked and dnsmasq-base is already installed but dnsmasq is not. I do have dnsmasq in /usr/sbin but the package description makes it sound like this should come with dnsmasq. Is the page out of date? Will uninstalling dnsmasq cause other problems?

I have a server with 2 network cards. eth0 is used for all traffic and everything is working fine on this side. Eth1 is used for traffic to and from 1 ip address.
Lets say the ip address of eth1 is 123.123.123.10 and its gateway is 123.123.123.1. I need to pass all traffic to 123.123.123.20 through eth1. What command would i use?

How do I tell the shared connection that it has a static IP and that I dont want a DHCP on the network?Do I have to set up DHCP on the box with the shared connection, even if that box only runs DHCP for a single IP address being the eth0 that is shared?Or can I tell the shared connection that it has a static IP and still allow network manager to run the shared connection?Or should I specify static IP's for all clients and the shared network manager and install say firestarter on the gateway to run the NAT for the eth0 out to eth1.

I have a wired lan at home with 2 XP boxes connecting to a router to a DSL modem. I want to network my laptop, running only fedora os, for file sharing, printing and internet access. I will be using the laptop probably exclusively for creating/maintaining a Drupal-based (LAMP) e-commerce site to replace our old one for our small family business.

Heres the set up I have: one eeepc running ubuntu netbook. with a usb wifi dongle, this is connected to a parabolic antenna i made out of pizza boxes and tin foil. One fujitsu laptop running ubuntu 10.10. the eee connects to the internet via the dongle. then the laptop connects to the eee. I set this up by using network manager. I created a new wirless connection and called it "UbuntuAdhoc". The on-board card connected to this without issue and the laptop was able to connect to the new wireless broadcast by the eees on-board card.
This worked perfectly untill I rebooted the eee. Now the eee is unable to conect to the internet if the on-board caard is conected to "ubuntuadhoc". also the dongle now wants to conect to "ubuntuadhock" too.

I run an Ubuntu Server in a Virtualbox environment. Setup works fine. In virtualbox, I accidentally hit a button that generates and assigns a new mac address for the network adapter. Since then the machine does not bring eth0 up. I tried the following ifconfig eth0 down; ifconfig eth0 hw ether macaddress; ifconfig eth0 up. Then restarted networking.

I've got two network card interfaces on my computer, one wireless and one wired. The wireless card is connected to the Internet and the wired is connected to the LAN. When only the wireless card is active, Internet works. As soon as i enable the second wired card, Internet stops working. And it seems like Ubuntu chooses the wired card for Internet as soon as it's enabled.
Are there any ways to solve this? So my Ubuntu box always chooses the wireless card for Internet traffic and let me use the wired device for LAN only?

I'm using ubuntu karmic and I'm not able to connect to the internet with my reliance netconnect data card using network manager. Other distros like fedora, opensuse n sabayon connected easily with nm. Ubuntu detects the data card flawlessly but just doesnt connect.This problem has been persistent even in previous ubuntu versions, n I used to use wvdial. But downloading wvdial on some other comp with every dependency is really cumbersome.

Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:

To add a new IP address for the network card in the fedora, the only thing I have to do is to copy the file ifcfg-eth0 which is under /etc/sysconfig/network-scripts/ to a new filename called ifcfg-eth0:1 and change the IP address and the DEVICE?
OK, what about other files as following code...
They will be changed automatically if i changed the file under the network-scripts or i have to change them manual?
Am I miss any thing else need to be done?

I have a MediaGate MG35 which allows me to play movies and things via my network from my computer. This worked fine with Vista, but when I upgraded to Windows 7 the samba sharing changed and my MediaGate was no longer able to gain access to my shares on 7. My solution was using VirtualBox with Ubuntu. This worked fine on 9.10. I did this by creating a folder in my /media folder called windows-share, giving it a share called movies with Guest access. and then adding the following line in the rc.local file to mount the windows share though VirtualBox:
mount -t vboxsf movies /media/windows-share/
(movies being the name I gave the shared folder in VirtualBox) So I had to do was start the VirtualBox and everything was setup without me having to do anything. This then allowed me to get to my movies saved in windows with my MediaGate. This worked great. I've now got Ubuntu 10.04 on a new VirtualBox. I've set up everything the same, but when I try to access the shared folder, it doesn't work. If I try to access it with windows, it says that the share is not accessible or I don't have access. This ONLY happens to the folder that has been mounted to, any other folder I share works fine.

I have a laptop running Windows XP with a secure wireless internet connection. I want to share this connection to my desktop running Ubuntu 9.10 via an direct ethernet cable connection. So far in Windows I checked the "Allow other network users to connect through this computer's Internet connection" in the Wireless Network Connection Properties menu. Doing this creates a new IP Configuration. Here is an output of running the ipconfig command: Windows IP Configuration
Code:
Ethernet adapter Wireless Network Connection:
Connection-specific DNS Suffix . : home
IP Address. . . . . . . . . . . . : 192.168.1.3
Subnet Mask . . . . . . . . . . . : 255.255.255.0

I have an Ethernet hub, and want two computers (both notebooks) to share my internet connection. One is running Ubuntu 9.10 and the other is running Windows Vista. I want both computers to be able to connect to the internet (I use a cable modem).
However, when I plug both computers in, I am able to get only one of them working at one time. When Ubuntu works with the internet, Windows does not work (although it sees the internet connection). When Windows works, Ubuntu sees the connection, but cannot connect.

I'm trying to share an internet connection between two computers. The one currently online is a HP Presario running Ubuntu 9.10, and connects through a wireless connection. It has an ethernet port, which I'm hoping to use to connect to a Dell Desktop running Windows XP pro SP 3. I'm hoping to make this happen one of two ways.
1. Without having to mess with any DHCP settings. Sadly, I live with my parents, and the router in their room uses DHCP and sets the addresses for all the computers on the network. My parents don't want me screwing with any of the settings on the router. is there a way to just have Ubuntu pass information from the ethernet connection to the wireless connection without having to deal with DHCP.
2. I'm sure this has been explained, but as I'm new to Ubuntu, I will pretty much need step by step instructions to do this part. Sorry to be difficult. Is there a way to have Ubuntu keep the current settings it has on the wireless side (let the router determine it's address and all of that good stuff), but have a DHCP server kick in on the hard-wired side so Internet Connection Sharing has an address to look for on the laptop?

I want to use the wifi card in my laptop to share my internet connection to my Android Phone.Android phones don't support Ad-hoc networks yet (maybe not ever) so I need to the shared network in Infrastructure mode not ad-hoc mode.Using Ubuntu 10.04, If I click on the NetworkManager Applet ( 0.8 ) and select Create new wireless network, it will create an ad-hoc network, I then tried changing this to infrastructure, but it didn't work.Is there some way of modifying this created network to make it appear as infrastructure, or alternatively create a shared internet connection in infrastructure mode?

Just took the plunge and removed Windows 7 from my desktop rig and I am currently using Ubuntu 10.04
I was using this PC to share my Internet (DSL) connection to any and all other PC's on my network, wired and wireless, and I am attempting to set this up in Ubuntu.
My desktop, other wired PC's, a wireless AP and my DSL modem are all connected to a 8 port Ethernet switch and I was using ICS in Windows 7 to share my Internet connection once I established the connection from my desktop.
Can this be done in Ubuntu? As soon as I make the DSL connection it says that Auto eth0 disconnects (which I set to share to all in IPv4 settings which I read on the forum is the way to share)... thus nothing is currently shared :/
In this document it states that the sharing computer needs two network interfaces... but in Windows I only used the one...

The place I will be staying at (Japanese Guesthouse) only offers internet through cable. What I'd like to do is be able to connect my other devices through wifi (Cellphone for example) to the Ubuntu machine connected through this ethernet cable in order to access the internet.I've searched for a good hour but I'm getting extremely confused about the gateways, bridges or whatever else people suggest. Most of what I've been able to find actually only covers getting internet through wifi and then sharing it through lan (I'm trying to achieve the opposite).
So if anyone could point me in the right direction, or at least tell me what terms I should be using for my searches, it would greatly help.Some computer info might be useful. I'm using a Dell XPS M1210, the network adapter is an Intel Pro Wireless 3945ABG and I'm running Ubuntu Desktop Edition 10.10.

I have a desktop PC and a laptop, both running Ubuntu lucid, the laptop has XFCE and the PC has GNOME, but that's actually not relevant.My PC is connected to.I can't access the internet from my laptop, but whenever I connect the two machines with a network cable, my PC sees the connection at eth0 (even announces connection and disconnection), but my laptop does not.I have no idea what's going on, could this be a faulty cable or a faulty network card at my laptop? Or I simply screwed up the connection setup?
