Ubuntu Networking :: Sharing 3G Connection Using Adhoc Network

Aug 4, 2010

Here's the setup:
I have 2 laptops:
1. Dell Inspiron 8600 with an intel 2200BG wifi card (Ubuntu 10.04)
2. Asus eeePC 1000 (Ubuntu 9.04)

Internet setup:
Laptop 1 connects to a 3G connection and shares it with laptop 2 using an ad-hoc network.

I upgraded to Lucid on Laptop 1. Prior to the upgrade everything was working. Now, when laptop 1 tries to connect to the ad-hoc network it almost immediately disconnects and tries to reconnect again.

Ad-hoc network settings:
The ad-hoc network uses a WEP key. In IPv4 settings, "Share to other computers" is selected.

Dmesg output:
Code:
are: requesting ipw2200-bss.fw .....
** (nm-applet:4259): WARNING **: _nm_object_get_property: Error getting 'Default' for /org/freedesktop/NetworkManager/ActiveConnection/327: (19) Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist

Ubuntu Networking :: Internet Sharing Via Wireless Adhoc Connection

Nov 3, 2010

I am trying to establish an adhoc connection in my ubuntu 10.10 and share my cable internet throughout this connection with my Android phone. I have read some guides but I couldn't be successful. (I have another windows mobile, and it couldn't connect too). I have installed Firestarter in order to enable internet sharing. My main Problem is that, no one can obtain IP adress from the adhoc connection, whether Firestarter is active or not. What should I do in order to make the other devices gain IP address from this connection. If I have to set static IP what should I do exactly?

Ubuntu Networking :: Can't Connect Wireless Connection On Adhoc Created In Windows 7

Apr 12, 2011

I'm using Ubuntu 10.10 (Maverick Meerkat) on my HP laptop. My office desktop uses Windows 7 Home Edition. I created an adhoc connection on my desktop pc because I also want have an internet connection on my laptop. But Ubuntu seems do not detected the adhoc I created on my pc. I also tried to connect using the hidden wireless network and entering all the necessary access (wep key, etc...) but still didn't work. Is there any way that I could connect my Ubuntu on a adhoc? Is that possible?

Ubuntu Networking :: Connection Sharing With Network Manager And Dnsmasq?

Jan 1, 2010

how to change the IP range provided by default by Network Manager / dnsmasq from 10.42.43.-- to something else?

I have setup a working network using a Bell wireless modem (Canada) and Network Manager in 8.10, 9.04, and 9.10.to do Internet connection sharing. In 8.10 the only way I could get it to work was with WICD and KPPP, many hours spent on this one. I got it to work in 9.04 and 9.10 using network manager, but certainly not out-of-the-box. If someone would like some tips on how I did it, in each case, let me know.

My current challenge is trying to set the dhcp range of dnsmasq (which I am 99% sure is what is handing out addresses) from th 10.42.43.-- address range to a 192.168.0.-- range.

I HAVE edited /etc/dnsmasq.conf and can get the edits to this file to break the setup (dnsmasq will not start) but have not been able to get it to change the IP address range.

It seems that either this file is ignored, or overridden by some other process. I have looked at the very good post at [URL] about dnsmasq but this does not do the trick.

By the way, the way I can get this to work is to start NM, establish my cellular internet connection, then kill dnsmasq then establish my ICS network (on eth0). If I don't kill dnsmasq, then it does bring up the connection, but it then shuts down in a matter of seconds. It is all very manageable using a launcher (kdesudo pkill dnsmasq) on the task bar, but not all that elegant.

the IP range and where this is provided to Network Manager or the network itself is my real question now.

Ubuntu Networking :: Sharing Network Connection From Laptop To Desktops?

Nov 21, 2010

I got a laptop with wireless. Next to it I got 2 desktops, neither of which have a wireless card and I don't have any usb wireless adapters or anything. I do however have an ethernet cord. In the past I was able to set my eth0 connection to be "shared to other computers", then from my laptop I could run the patch cable to the desktop and voila, internet to the desktops.

For some reason though, now whenever I try to connect from the desktops, there are 2 green circles and a little blue circley thing going around them. it spins for a while and then says disconnected. Also, now if (on my laptop) I connect to the wired network, my wireless stops working. I'm kind of stumped here, I tried deleting both connections from both computers, setting everything up again, and connecting, and I get the same problem. Also seeing as how I'm trying to troubleshoot this from my laptop and watch this thread, I can't exactly mess around with it much right now or I won't see any replies.

Ubuntu Networking :: Sharing Internet/LAN Eth0 Connection Via Wi-fi Ad-hoc Network

Dec 1, 2010

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?

Fedora Networking :: Connection Sharing With Network Manager

Dec 21, 2010

I'm trying to share internet connection with my wifi capable mobile device. For that I'm creating ad-hoc wifi connection in networkmanager with 'shared to other computers' ipv4 option. And there is the problem - the device cannot get the setting via DHCP. The firewall is adjusted properly by NM, dnsmasq is started. I've looked at dnsmasq arguments string and found that the temporary config file which is provided by NM is empty. So, where else should I look for a possible reason or should I just post a NM bug?

Ubuntu Networking :: Internet Connection Sharing In Network Manager / No DHCP Server

Oct 14, 2010

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.

Ubuntu Networking :: Internet Connection Sharing (not Using Ad-hoc)?

Aug 4, 2010

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?

Networking :: Internet Connection Sharing In Ubuntu

Mar 5, 2009

A friend of mine is trying to setup internet connection sharing in Ubuntu, which is something I've never dealt with before. Here's the situation:One desktop PC is dual-booting Ubuntu and Vista. This box is connected wirelessly to the router and can access the internet just fine. The desired setup is to have an xbox360 connected (wired) to the desktop PC, allowing it to share the internet connection.

1) A crossover cable would need to be used between the desktop PC and the xbox.
2) The xbox would still have the router's internal IP as the default gateway (I have zero experience configuring networking on an xbox... I hope these options are easily available).
3) The internal IPs can all be on the same network (i.e. router = 192.168.1.1 ; desktop = 192.168.1.100 ; xbox = 192.168.1.101)
4) IP forwarding would need to be enabled on the Ubuntu host

Is there anything I'm overlooking or just oversimplifying, or should that just about do it?

Fedora Networking :: Wired Networking Not Connecting In 12 With Windows Internet Connection Sharing?

Jan 16, 2011

I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.

Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.

Ubuntu Networking :: Internet Connection Sharing Via Firestarter?

Feb 5, 2010

At my home I am using firestarter to connect my XBOX 360 to the internet and it works perfectly, never crashes etc and I get a moderate NAT which I've never experienced any problems in having.

I have my devices set up like this

eth0 - ifconfig eth0 192.168.2.1 netmask 255.255.255.0 broadcast 192.168.2.255
XBOX - 192.168.2.10 netmask 255.255.255.0 broadcast 192.168.255 gateway 192.168.2.1

This configuration works perfectly on my router at my house which has the IP of 192.168.0.1

However at my friends house he has a router with the IP adress of 192.168.2.10 or 192.168.2.7*, I don't remember exactly but I'll find out tonight. I have tried changing my IP settings on my xbox and eth0 to no avail. I noticed instantly that the XBOX IP is the same as my friends router. what the new settings would be, or simply changing the router's IP.

However there is also an issue with the DNS servers. I can't find them anywhere on the router or on the router box itself. I heard that I could point it towards my default gateway however.

Ubuntu Networking :: Internet Connection Sharing With Windows 7

May 4, 2010

i have an evdo connection with which i connect to the internet. i have been trying to share this connection for quite a few days from my lucid machine to a windows 7 pc but have failed. i have tried dhcp3-server, firestarter, network manager's built in capabilities but have failed! today i manually configured da windows 7 pc to an ip address within da range which network manager ws assigning when 'shared to other computers' ws selected and it worked! Now da question is how do i do it automatically? dhcp3-server never starts, it always fails with the error 'not configured to listen' or sumthng like it! Plus i want the wireless of my laptop to make an ad hoc connection to my mobile fone, which is also no possible...i think its some problem with da dhcp server.

Ubuntu Networking :: Sharing 3g Connection On 10.04 And Vista Via Router?

May 28, 2010

i'm totally new to Linux and Ubuntu. I own a huawei 3g modem through which I connect to the internet. I plan to share the internet from that connection between my Vista pc and another pc running Ubuntu Lucid Lynx. The computer I plan to use to share the internet, let me call it Server, is equalling running Ubuntu Lucid Lynx. My Server perfectly recognises my modem and connects to the internet using it and I can browse.

I plan to connect the routers internet port to my Server using my servers network card. Then i intend to let the router do the sharing of the internet to the other computers on its own. I don't have any idea how to go about doing this. Originally, I tried a direct connection between my Server and the other pc running Lucid Lynx without bothering with the router and using the following settings which i found on an online tutorial:

Server ip 192.168.0.1
netmask 255.255.255.0
and no gateway
then on the client
client ip 192.168.0.5
netmask 255.255.255.0
gateway 192.168.0.1
I used open DNS servers for the DNS

However, i was unable to browse the internet from the client even though a connection between the two was established. Then I thought to myself, why go through this trouble, I have a router so why not go ahead and use it. But then I do not know how to do that. Using the router will enable me to effortlessly connect all my computers irrespective of operating system and ease the network creation process.

Ubuntu Networking :: Sharing A Windows XP VM Internet Connection?

Jun 20, 2010

I'm trying to share the internet connection of my Windows XP Virtual Machine (virtualbox) to Ubuntu. I know it sounds weird, but what happens is that i'm using a 3G modem to connect to the internet and 3G connections are still very unstable with ubuntu's network manager. Fortunately, the modem works a lot better with my Virtual Machine. I have already set up a "host only" network between my Windows XP guest and my Ubuntu host and i can they can ping each other but i still can't share the connection of my virtual machine. I already selected "share this connection" on win xp but i think i still have to configure something on ubuntu for it to work. The interface Ubuntu uses is vboxnet0 (not eth0).

This is the last thing to do before i can get rid of my Windows XP partition

Ubuntu Networking :: Internet Connection Sharing To Windows XP?

Nov 18, 2010

configuring Internet Connection Sharing from my Ubuntu 10.10 machine to a Windows XP machine. I've seen How To's but they didn't work, yet.

The Ubuntu machine connects to the Internet through a DSL USB modem that required packages not provided with the distribution, and specific instructions to configure it; so getting Internet working alone was difficult. As a result, I don't even use Network Manager, rather connect using the command pppoe-start. The machine is connected to the Windows PC through a simple cable, through the Ethernet card.

Some tutorials I've seen on ICS are for machines with two Ethernet cards, or for wireless connections; but I've seen none for a USB modem. However I once found one, years ago, and it worked, but I couldn't find it now. It was using iptables, and I didn't really understand what I was doing, but it worked. But then I had to format the disk, and now I can't find a way to get it working again.
