Ubuntu Networking :: Sharing Internet Without Having To Set Up DHCP
Mar 18, 2010
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?
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 did search, but could not find a solution.Right I've installed Ubuntu Server 10.10 on an old machine, installed fine and the system is running. I have a windows 7 desktop that is connected to the internet via wireless. The desktop then has an ethernet connection which is shared to the ubuntu server. The network looks like this.
Modem > Router > Desktop > Switch > Ubuntu Server My problem here is that there appears to be no connection from the server to the desktop. The server cannot connect to the internet.
When i ifconfig the ubuntu machine shows.eth0 link encap:Ethernetinet address: 192.168.137.2 Bcast:192.168.137.255 Mask 255.255.255.0 However on the windows desktop (the machine sharing the internet) these are the details for the connection to ubuntu server.ip 169.254.170.50 mask 255.255.255.0
is this a dhcp problem? is my server configured wrong?
I have a similar problem. My ubuntu box is set up as a dhcp router for my Xbox360, my xbox can get ip and DNS information from the computer, but it doesn't seem to get the right info. The ip address it gets assigned is out of the range I've set in etc/dhcp3/dhcpd.conf.
I'm trying to set up a wireless AP with Internet sharing. I currently have the AP setup with hostapd and a dhcp server. The clients can connect but there is not Internet sharing. Now my situation is somewhat uniqe in that my internet connection is my teathered android cell phone. The tether app is azilink and i use openvpn to create a virtual networking interface(tun0).
I have little question, how can i share internet in Ubuntu? In this case to Win 7? I have tried Firestarter, but that doesnt work... And please I do not have a router I just need simple connection from my desktop to my laptop, and I dont want another box collecting dust.
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
I am using Ubuntu 9.10 and trying to use Internet Connection Sharing through my Dell Mini 9 laptop.
The incoming internet is from wireless The outgoing internet is from Ethernet I am using a crossover cable as I have heard this is necessary I followed the 9.10 method on my Auto Eth 0 connection Here is a link to the Ubuntu Documentation I used The computer I am trying to share to does not pick up the internet being shared from the cable.
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 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?
i have 2 laptops which is one installing windows 7 and the other one is ubuntu 10.04. i have internet on windows 7 and want to share to linux ubuntu 10.04 through wireless connection. How to setting that?
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?
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.
for the last one week i'm facing problem in sharing internet between xp and fedora. I'm connected to internet through wireless adapter in xp and wants to share internet through crossover cable between xp and fedora. I did the following steps.
1: start a network setup wizard in xp. 2: change the smb.conf file in fedora and change the workgroup name to same as in xp. 3:in Xp the ethernet adapter has address 192.168.0.1/24. 4: when i connect the crossover cable and start fedora. it couldn't get the ip address through dhcp. 5: when i tried giving the ip address manually "192.168.0.2/24 with gateway 192.168.0.1"and save the subnet mask is replaced by 192.168.0.1 don't know why it not saved.
i tried changing new ethernet card but not worked. some time avc denials message "SELinux is preventing consoletype (consoletype_t) "read" to /var/lib/dhclient/dhclient-eth0.leases (dhcpc_state_t)." comes. can any one tell me how to enable or make a network in fedora . i 'm very new in linux and couldn't able to share network .
I'm trying to use my bluetooth connection on Opensuse 11.4 to share its internet access with my Windows 7 laptop.I've been able to link them together(send receive files) but cannot create an Adhoc network or share internet with the link.What should I try? Could someone point me into the right direction?I looked at one promising tread that looked as if it would work but cant find hcid.conf(did a complete file search and think it may have been changed in bluez).
I've been connecting to the Internet via Ubuntu 8.10 on my Toshiba laptop fine for ages now, but today it has stopped working. Yesterday an update came through relating to DHCP and, like all other updates, I installed it. And now my laptop can see the wireless router but it cannot connect to the Internet. (As I always install the recommended Ubuntu updates I didn't look closely at exactly what the update said, but I did see DHCP in the title, so this is why I suspect my connection is now broken.) Or can anyone tell me how to undo yesterday's update? I really wish now that Ubuntu had a utility similar to Windows System Restore.
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.
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.
I have been looking for a solution to an apparently simple problem, but could not find anything for Lucid. All solution I found imply modifying files that apparently don't exist anymore (/etc/default/bluetooth, /etc/bluetooth/hid.conf, ...)I have an old laptop running Xubuntu (lucid). Internet card is dead but it has a bluetooth adapter in the USB port. I also have another laptop with internet, wireless, and bluetooth on board. How can I configure both so that the first access the internet trough the second?
- Internet works on the second (of course!)
- Bluetooth work on both, I can pair them and send file from one to the other (although I cannot browse them, but it seems to be an unrelated problem)
- I have blueman on both and tried to configure it to do what I want but it did not work (old computer has a bnep0 interface, but no address for it)
- Old laptop sees "Network access point" and "group network" as bluetooth services of new laptop (although I did uncheck "group network" in the local services setting on new laptop)
- as I said I looked on the web but only found solutions that appear to be designed for older versions of Ubuntu because they refer to non existing files on my two laptops.
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
is there any way that i can share my computer's internet connection with my iphone. i've tried to set up an AD-hoc network and bridge it with the internet-connected interface but i ended up with no connection in both the pc and the iphone. im using ubuntu 10.04 lts and i have 2 wireless cards it will be great if i can use the usb cable to share the internet.
i have searched and searched for an answer but nothing i've found has worked for me what i have is an old computer with 2 network cards in it the 1 conected to the internet is eth1 one connected to the xbox via crossover cable is eth2, what i'm trying to do is share the internet connection to the xbox using ubuntu,i've tryed alreadyusing the network manager,using firestarter,ip tables,even nat,and all have failedi've been using ubuntu for 4yrs now, and i have always before been able to find answers to my problems by simply googling the answer. but this is one i can't seem to find an answer on.
I have BSNL EVDO usb modem and I use wvdial to connect to internet in my Ubuntu 10.04.I want to share my internet over wifi so I can use this on my wifi phones. I searched all over and actually ended up here.
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.
