Ubuntu Servers :: DHCP Connection Sharing - Connected To The Internet Via Wireless?

Dec 29, 2010

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?

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.

General :: Internet Connection Sharing - All Traffic From The Ethernet Connection Out Through The Wireless

Jun 25, 2010

I would like to have all traffic from the ethernet connection out through the wireless (basically using the box as a router) however I am having some trouble doing this.

I have done this before on Windows however I am having some trouble doing this on linux, I have tried using Squid Proxy however I am having some trouble using configuring/using it.

I am using Yellow Dog Linux however I am willing to change to any other distro as long as it is compatable with PS3 (as this is what im using linux on)

Ubuntu Servers :: Internet Connection Sharing

Jan 20, 2011

I have discussed sharing an internet connection with my neighbor so we can both save money. We both have multiple computers connected to consumer grade routers. I've tinkered with WDS configurations but it was very unreliable and cumbersome to manage for reasons I won't get in to here. I'm thinking of getting my ubuntu server box to connect to my neighbor's wifi (via a USB wifi adapter) and share the connection through my router to my own subnet, (wired and wireless).

Can anyone shed some light on how I can best accomplish this?I can see a number of hurdles with this, maybe there are some I have yet to discover:Getting the USB wireless adapter to connect and stay that way via commandline.Configuring ICS from the USB connection to ethernet out to my router.Probably moving DHCP duty from my router to my server.Getting it all to work reliably well.

Ubuntu Networking :: Sharing Wired Internet Connection To Wireless

Aug 29, 2010

For the last 3 or so hours I have been trying in vain to simply give my mobile phone wifi internet access from my netbook. I have tried to google and follow some howto's and guides, but they're either too old or don't explain it very well. I'm fairly new to use of Linux and of wireless networks, but can handle setting them up in Windows. So basically, having said that, I believe I mostly understand how this whole thing is supposed to work theoretically but I just feel as though I lack the experience to jump the wireless hurdle AND the Linux hurdle at the same time. I have provided some information below.

- Setup is based on Lucid netbook remix install with a Maverick kernel update due to lack of driver support for wireless NIC - I can confirm wireless does work properly for connection purposes
- I followed [URL] and kind of followed [URL however I couldn't even tell how to run Network Manager, even though Synaptic tells me it is installed
- When I ran into problems trying to install ipmasq I found [URL] and followed what the response told me to which allowed me to restart the dnsmasq and the dhcp3-server at least
- I have restarted the entire netbook several times throughout the process.

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 Installation :: Linksys WUSB54GC Wireless Connected But No Internet Connection?

May 7, 2010

I am closing this thread and ask this question in the "Network and Wireless" area. As for the installation of 10.04 - wonderful. However, my problem is not an installation problem. Ubuntu 10.04 - Fresh install on machine with no previous OS it was a beautiful install experience. I have a Linksys WUSB54GC little plug in thing that is in one of the USB ports At the top of the screen it says that the computer is connected to the network genevapubliclibrary 100%

But when I access firefox, there is no internet connection. I checked the Preferences, Advanced, Network tab, Connection and the Settings button. It is set to "No Proxy". This is the same setting as our library laptop - also wireless - in firefox but using vista. If this has been addressed elsewhere, I apologize. I tried looking for linksys wusb54gc but no one had this problem.

Ubuntu Networking :: Wireless Sharing - Unable To Connect To The Internet If The On-board Card Is Connected To "ubuntuadhoc"

Mar 22, 2011

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.

Fedora Networking :: Internet Very Slow / DHCP Doesn't Work W/ Wireless Connection

Jul 17, 2009

I am a convert from Ubuntu (9.04 kept freezing on my laptop; when it did work, many packages it seemed were outdated--ie only Eclipse 3.2, rdesktop was messed up [and apparently is also in Fedora]), and I am having some trouble with getting my wireless working.I am running Fedora 11.First off, there is a problem when trying to connect when using DHCP. NetworkManager gets to the second green dot, and then after a short while I am given a message that the connection was disconnected.

Configuring the interface manually, not using DHCP, allows the connection to complete. However, the internet is very slow. There is a 15-30 sec delay before website loading actually commences, and then another delay each time an ad must be fetched from another server.How can I fix this delay? I know I have encountered it in earlier versions of Ubuntu, but I can't remember how I fixed it.About the rdesktop problem, if anyone is able to help [maybe I should post another thread?], the cursor color (the color of the pointer) is inverted---where it should be white it is black, and where it should be black it is white. I use rdesktop a lot to connect to my terminal server in my basement. Any idea how to fix it?

Ubuntu Networking :: Internet Connection Sharing : 3G/4G USB Dongle And Netgear WGR614 Wireless Router?

Jan 1, 2011

I have internet access through 3G/4G USB dongle direct into my Ubuntu 10.04 box. Works great! Now I would like to share this connection out through my Netgear WGR614 wireless (and wired) router. Any clues? I've tried the simple (GUI) instructions using Network Manager, but just can't seem to get it right. Previously, I had DSL and this plugged nicely into the WGR614 and internet and ethernet access was had by all. Now, I'm a bit confused on how to get the sharing (ethernet and wireless) between my Ubuntu box and the wired/wireless network while at the same time getting Internet access to all through the Ubuntu box.

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?

Ubuntu Networking :: Wireless Connected But No DHCP

Mar 6, 2011

I had the wrong WPA password.[/blush] It appeared to me that it was connected OK at the physical/datalink level but apparently that was not the case.I've set up an old PC with the latest Ubuntu desktop and am trying to set up wireless networking with a TP-Link TL-WN722N. It only came with Windows drivers but from a thread elsewhere I got it to where it finds my router and connects with the password. However, it doesn't pick up its IP details. The router is working fine wirelessly on my phone and wirefully on my other PC.

I've edited /etc/network/interfaces with "auto wlan0" and "iface wlan0 inet dhcp" but after restart the wlan0 interface has no IP details. Originally the interface had IPv6 details but I cleared that with ifconfig. Under the Network Connections Wireless tab it has "Auto" followed by the name of my wireless connection so it appears to have connected OK. Now when I click Edit for that connection nmame, the IPv6 tab says Ignore and IPv4 says Automatic (DHCP) but Addresses is greyed out and the other fields are all empty.

Networking :: Get Connected To A Wireless Network That Only Allows DHCP?

Jan 16, 2009

I have a WET54g bridge that I am trying to get connected to a wireless network that only allows DHCP. The idea behind it is that I would like to connect the Cat6 out of the bridge to a switch allowing multiple wired computers to connect to the wireless network. The bridge will easily connect to the network once I put the WEP key in, however, there is a kink after that. When I connect the Cat6 to my computer and request an IP for that computer, it self assigns. This tells me that it is not talking to the wireless network through the bridge.

I can not find which IP address the bridge was assigned so that I can talk to it. The sub net is 255.255.240.0 which leaves quite a few possibilities. I know that the bridge is, however talking to the wireless network because the light is steady on the front of it which indicates just that. One other thing to stack on is that I know that there is a "splash page" which comes up when any computer connects. You click on the agreement and then you are allowed onto the network. How can I get my computer to talk through the bridge to the wireless network?

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?

Ubuntu :: Internet Connection Sharing - Not The Standard

Jan 8, 2011

So - i got it to work - ish.

first of all the hardware that's involved:

2 wireless cards

The goal is: using a monospace font

Code:

I hope this diagram shows my intentions, how i may have an internet connection via phone or wlan1 share it with eth0 and wlan0

Anyway as i said, i have done _some_ of this, this is where i get stuck i did this (while as SU)

Code:

I then configured dnsmasq using the settings on that page

I then plugged my laptop into the switch and tried to connect- IT WORKED I then plugged my computer into the switch - IT DIDN'T xbox 360 didn't work.

But the laptop still did

I used firestarter along side this setup to see connections, nothing was blocked (bar dns which i unblocked) and my laptop still worked after

The xbox wasn't able to get an IP adress, the laptop did (192.168.254.246)
nor was the computer

I can give more data on request, but.... after i restarted nothing worked, i did the settings again, nothing worked, eth0 was never ready, and you can't connect it to the switch. i'm new to networking; i'd call myself an adept novice regarding linux itself, and all computers can be assumed to be using ubuntu 10.10

Ubuntu :: Internet Connection Sharing With Vista?

Apr 19, 2011

I have two laptops connected to each other with a crossover cable. One laptop runs vista and has internet connection sharing enabled and the other laptop has a new installation of ubuntu server 10.10.

The LAN network device is configured as 192.168.0.1 and is on subnet 255.255.255.0.
The ubuntu network device is configured as 192.168.0.1, is on subnet 255.255.255.0, and uses gateway 192.168.0.2. Those are the values that I entered in /etc/network/interfaces.

The laptops are able to ping each other but I am not able to connect to the internet on the ubuntu machine. Am I missing something here? I did

Code:
sudo /etc/init.d/networking restart

and also rebooted the ubuntu machine but no luck. I am unable to update apt-get.

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?

Ubuntu :: Shared Internet Connection 10.04 - Cannot Get The XBox Connected

Jul 11, 2010

I just got a new XBox 360, and I would like to get it connected to the internet.

I cannot run hardline Ethernet to it, as the nearest line is across the house.

I have, in the past and on friends machines, had success setting up a shared internet connection from my Ubuntu box to the XBox in question. I would always follow this guide, and it would work right away. [url]

Recently, I have purchased a new wifi router. This has changed the DHCP makeup of my home network from 192.xxx.xxx.x numbers to 10.0.0.x. I dont know why, but thats how the Netgear router set things up. I have reserved addresses 10.0.0.(2-4) for specific computers because of remote access needs, anything above 10.0.0.5 is empty.

Following the guide that I linked above, I cannot get the XBox connected.

I believe that the fact that the rest of the network is listed under 10.x.x.x may be the culprit, as the DCHP server on MY computer would be assigning the same Local IP as the other devices on the network. (I.E. Giving the XBox 10.0.0.2 and my computer 10.0.0.2)

To clarify how my network is connected; this is how the network is setup:

Internet/Phone line ---> Verizon Westell DSL modem in 'bridged mode' (IP 192.168.x.x) ----> Netgear WGR614v10 Wireless (IP 10.0.0.1) ----> Computer connected via wifi (10.0.0.x) ====> Shared connection to XBox (IP ? supposedly 10.0.0.x)

Somewhere between the computer and the shared connection, The xBox is getting lost, and cannot connect. The troubleshooting shows that it could connect to the network, but it cannot access the internet as a whole.
