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.
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.
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.
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?
I have two ubuntu systems. Both are not connected to any internet connection Both are not connected to any DHCP server. Both are connected to each other via simple 8 port switch.
Is it possible to share files between two ubuntu systems ?
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 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've read a lot on the internet about various ways of doing this but i've been unsuccessful each time. Basically what i've done is accidently un-installed network-manager because I was having trouble staying connected on my WPA network. The easiest way of reinstalling it I know of is using the CD but I don't have a CD ROM drive and the pen drive I used to install it I no longer have.
I tried using a program called Keryx but you need python installed and from some reason this doesn't come with ubuntu 10.10. I've also downloaded the .deb packages but I still need to download 200kb which is a killer. I've also downloaded it from here too [URL] but the install file makes no sense to me as i'm not a massive linux user. One last thing reinstalling isn't really an option as i've already put a lot of time into setting up this computer.
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 have a Ubuntu 10.04 laptop that gets its Internet connection via WIFI using WICD as network manager, and Windows XP desktop with no Internet connection. What I want to do is share my Internet connection from my laptop with my desktop via a Ethernet cable. But i have no idea what to do. How do i go about doing this?
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 recently installed fedora 15 on my computer but I have a huge problem. I can connect to my router wirelessly for a couple of minutes only. Afterwards my computer has no Internet connection although the network manager and the icon on the upper bar says that i am still connected. I tried editing the /etc/rc.local and /etc/resolv.conf as mentioned in other posts in here bit no luck so far.
OpenSuse 11.4 Asus Netbook 1000H Following other members in the forums I have installed Opensuse 11.4 on the Netbook. In the early days Ubuntu Netbook Remix worked well for me. But this has been discarded, and the "one size fits all" Ubuntu had become slow and cumbersome. So..... onto my post. Opensuse is working well. The install went beautifully.
It detected the Wireless Internet and I am able to get on line. I also need to share the Internet connection to a desktop. This is done via a small network switch. Thus far I cannot do this. I tried to use ifup to configure a static ip but this busted my Wireless configuration. I went back to knetwork manager. Then I tried to set up the wired network using knetwork manager and under IPV4 "share" the connection. But this blanks out any possiblity of a static address and substitutes dhcp. My desktop cannot ping the this dhcp address. Ubuntu had this thing called Firestarter? - from memory. This configured the system to sharing the network.
This has already been asked, and answered here: [URL] but there is one problem, this requires a window manager, and network-manager. I am using Ubuntu 9.10 Minimal with no window manager, and i want to recreate the exact effects of the second post in the above thread.
I have one desktop (Ubuntu 9.10 Minimal) with a USB wireless adapter (wlan1) and an ethernet port (eth0). I want my second desktop (also 9.10 Minimal; connected to desktop 1 via ethernet on eth0) to recieve the connection through desktop 1's wireless. I realize this is rather easy with network-manager, but I am not sure how to go about it through command line.
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 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?
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've been able to make my server connect to my clients but not able to share the internet connection. I've been searching around but haven't come across an answer yet. Hoping someone here will point me in the right directiong. I have the following setup running. I'm trying to make an internet connection go through my server but haven't been able to get it to work.
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.
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'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
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.
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.
I have a laptop with Easy Peasy / Intrepid Ibex connecting to internet through wifi (firewalled VPN), a PC with Windows 7, and a crossed ethernet cable to connect them. How can I get Internet on the PC? I tried to connect them but I can't even ping each other!
I have a modem connected to my router (pfsense on 192.168.1.1) which is then connected to a wireless AP (192.168.1.253). A number of PCs pick up the wireless and all is well.I've just received another broken PC that I've kicked into life and was going to run a FreeNAS box with it to back up a number of the PCs on the network. I've actually hooked this up via ethernet to my "server" PC (192.168.1.125 on its wlan NIC). Its all set up so that the server eth NIC (10.42.43.1) is connected to the FreeNAS box (10.42.43.2) and the FreeNAS box can ping both interfaces of the server, the router and the net, and any other box on the 192.16.1.x network. The problem is that I can't for the life of me get any of the 192 boxes to ping the FreeNAS box. I'm presuming its a routing / gateway issue with the server box but being pretty damn hopeless with these things I've been stumbling about breaking things.
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.
