I am really bothered from this I cant configure the 2 nics to share the internet and I already changed the sysctl.conf file to # Controls IP packet forwarding net.ipv4.ip_forward = 1 I have one nic reeving the internet and working good and the other one cant see anything...
I have installed Ubuntu 64 10.04 server. I have two nics and have set them up to both be static with their own IP with the correct gateway, network, broadcast, subnet and dns-nameserver. When I have both enabled, I can ping local pc's but I can't ping Internet sites like Google nor can I get out to the Internet with apt-get or Lynx.
If I disable one, then I am able to get out to the Internet. All my configs look good, and it does not matter which one I disable, just so long as there is only one NIC on, everything is good.
I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
I have several Proxy severs set up at our business. I always do the same basic config, except for my version of Fedora (I always grab the newest).
I put 2 nics in a machine Load Squid, Dansguardian and Firestarter. I use Firestarter to direct the surfing traffic from my LAN out a cable modem that I have for each store. This lessons the bandwidth on the T1.
Easy enough. My problem is Firestarter has always been a little flaky. But as of F11 the gui wont stay up for more than a few minutes at a time. It still functions, but you have to be quick if your going to use it because it will inevitable crash.
So I suppose it's time to start doing this the correct way and using IP Tables. Does anybody have a resource they can point me to that will help me understand how to do this? It looks like this might be as simple as setting it up with the GUI Firewall tool that comes with F12 but I'm still not exactly sure how.
I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.
It is running Ubuntu server 8.10
The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.
My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.
I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.
I'm trying to connect two PCs to the Internet (or at least to create a local network) using a crossover cable. My main PC (the one that has two ethernet adapters and is connected to the Internet) runs Windows 7 and my secondary PC runs Ubuntu 10.04.Unfortunately, it doesn't work. Both systems send out packages but don't receive anything. How can I possibly fix this, so that I could use LAN and share the Internet connection between PCs? Does Windows need special software to recognize Ubuntu (or the other way around)?
Trying to share my internet connection with other computers on my LAN. I've tried doing this with Debian, Ubuntu & Fedora so far...
My Intended Setup is as follows;
The Problem: So far I've not been able to get an internet connection from any computer connected to the HUB. I currenty have Fedora 13 on PC1 but have also tried with both Ubuntu 10.04 & Debian Lenny. I am open to using any Linux based distro on PC1 as long it has a Gnome Desktop. eth0 on PC1 can be Static or Dhcp, but I would prefer to set Static IPs on eth1 & all of the Client PCs
To the best of my knowledge I have enabled ipv4 forwarding in sysctl.conf (& some other changes);
All changes I made to the Firewall (all other Firewall settings are still at default, no custom rules added yet);
Router is set up to assign dhcp from 192.168.xxx.100 & 192.168.xxx.200
At the moment I have only 1 PC attached to the HUB. It's Ubuntu 10.04 (PC2) It's details are; ip 192.168.xxx.103 netmask255.255.255.0 gateway 192.168.xxx.101
Thus Far I can't ping 192.168.XXX.103 from PC1 & I can't ping 192.168.XXX.101 from PC2. (unreachable) I have an internet connection on PC1 (of course)
i have two machines both on ubuntu 10.4 connected to a network via port switcher, 2 rj45 network cables auto eth0 is setup to share with other computers, i can ssh in and out of both, so the network is all running but i want to know how to share my single dongle internet connection between the 2 computers
I have two wireless cards on my pc. One connected to the Internet and one free. I would like to connect the free one to a adhoc network with my netbook to share my connection because my netbook cannot reach the other side of my home.
I want to share my internet connection with my netbook which has a Win 7 starter OS. This is what I did: in Network Connections I set the IPv4 Setting of my network card to shared with other computers, plugged in the network cable into both machines, and now they both see a connection. Win 7 only sees the connection as Unidentified network with "No internet access". What should I do?
I have an internet connection called 'tether0' in ifconfig.I also have a connection eth0 which is connected to a wireless router. I'd like to share the 'tether0' connection with the wireless router, so that wireless clients will access the internet through tether0.The guides I've seen don't seem to apply to my situation.how I should proceed? I'm not very experienced with networking,but understand most of the basic and intermediate terminology.
Note: To clarify the above example here is an example configuration that will work - * 1. You are already connected to the internet using your wireless on port wlan0 * 2. The ethernet port eth0 is connected to the PC that needs to share your internet connection (or you could wire eth0 to a router for multiple machines)
I am trying to do precisely this, with my laptop aready connected to the internet via my HTC Hero on port usb0, and the router needing to share the connection plugged into the laptop's port eth0. Port eth0 is set to "Shared" as the doc describes.
The router in question is an old WiFlyer pocket AP, which has a fixed and unchangeable IP address on its wired port of 192.168.7.77. What happens is that when I plug it into the laptop's eth0, NetworkManager pops up the "eth0 Connected" message...and then "Disconnected"...and then "Connected"...and then "Disconnected"...etc.
I want to be able to share my cellphone's Internet connection through the laptop and out into the WiFlyer so that others can get a wireless connection in a location that has no other form of connectivity.
[Rooting the Hero and making it an AP won't work: it can't run Froyo and it can't broadcast wireless.]
I am running Ubuntu 10.10 on several desktops but they are not close to my router. I would like to use a wireless connection to go from my router to my Ubuntu laptop, then a wired connection from my laptop to a desktop. My laptop is WiFi enabled and has an ethernet connection.
After some fiddling around, I have come to the conclusion my current wifi access point hates my other computer's Broadcom chip or the drivers thereof. So, my current idea is as follows. I would like to use my netbook to connect to the wireless network, and then connect my other computer to it through ethernet. My netbook is dual boot XP and Ubuntu (think Ubuntu is a version behind) and I would be fine to set up this sharing in either and just leave it on as a repeater station. My other computer is dual boot XP and Fedora and I would prefer this work to allow me to have network in both. I have a straight-through cable and have verified that my network card supports the automatic crossing over behavior.
Hello. I want to use my Debian box as an internet connection for a Win95 laptop. The laptop is old enough that the only port I have available to connect to the internet from is the serial port. I have heard that a serial port redirector will allow it to access the internet through my debian box, but I have no clue how to set one up. Any advice. Thanks
I have been trying off and on for weeks to share my Internet connection with a Windows XP client (netbook). While I can ping back and forth between the two machines, in the form of a ping test, I can't get to the Internet from the client, no matter what I try.
My Ubuntu 9.10 desktop (host) has two NICs, eth0 and eth1. eth0 connects to the Internet. eth1 goes to the Windows XP client. Regardless of whether I use an Ethernet crossover cable or a standard cable, I can get the two machines to talk to each other, but no further.
Things I already tried:
-Tried setting eth1 to "shared" mode in NetworkManager on the host. I set the Win XP machine to automatically acquire an address & DNS. Didn't work.
-Manually configured the IP settings on both machines, like this: client: address 10.0.0.2 subnetmask 255.255.255.0 gateway 10.0.0.1
Despite all of the above, I still cannot share the host's Internet connection with the client. I don't understand where the client's traffic is going, and why I can't share the connection. As far as I know, I am not doing any sort of firewalling or blocking on the host, so there is no obvious reason that the client's traffic simply disappears. I just know that whenever I open a Web browser on the client, all I ever get is error messages.
I have had no issues setting up a shared connection when the host runs Windows XP, so I am pretty sure there is no broken hardware causing the problem. Why can't I share the connection under Ubuntu?
My friend is trying to share his clearwire connection with me using Windows ICS. Using network-manager or wicd, I am unable to connect to his share. I am able to connect unencrypted with iwconfig, to the ad-hoc network, and then use dhclient to gain ip address.
I am not able to connect to WPA encrypted share using network-manager or wicd. nm-applet crashes when trying to connect. I am attempting to setup wpa_supplicant, but haven't got it working yet.As usual, the wireless networking out of the box experience in Ubuntu doesn't work. This is extremely frustrating. If Ubunut's goals are to be the default desktop, then these guys need to get wifi that "Just Works"...
I want to share my internet connexion via ad-hoc WiFi. If it's unsecured, it works fine, but when I use WPA encryption, it doesn't work anymore! I can connect from my iPod touch, but no internet. I connect to the internet from my laptop, via eth0 I want to share my internet connection via wlan0 I have no idea what's wrong
I have a computer running XP with a wireless Internet connection. I have installed Ubuntu 10.04 on a second computer. I would like to connect my Ubuntu computer to the internet through a wired connection to the XP computer. As I am a newby to Linux commands could someone explain how to do this in laymans terms.
Over the last several days, I've been trying like hell to share my (wired) Internet connection with a netbook, running Windows XP, attached via crossover cable to my desktop's extra NIC (eth0). The eth0 link is established, but I can't get to the Internet from the Windows XP machine.I can ping one machine from the other, but any bits sent from the Win XP netbook mysteriously disappear when trying to reach any website.
There is no firewall running on the Ubuntu machine as far as I know. Windows Firewall is likewise disabled on the Windows XP machine. The Ubuntu machine connects to the Internet through another wired NIC, eth1.In Windows XP parlance, what I am trying to do would be called "bridging," where eth0 and eth1 would be the two parts of the bridge. In fact I already made it work, with both the netbook and my desktop running Windows XP. It took about 5 minutes.I can't believe what a huge pain this has been in Ubuntu. I'm pretty much ready to give up. There seems to be no way to get an Ubuntu system and a Windows XP system to share an Internet connection.
I wouldn't be posting this if I hadn't tried very hard for the past week to do this on my own, but alas, I failed. I have this two configurations:
Desktop: - Ubuntu 9.10 - Connected to the internet though a wireless card - Connected to "Laptop" via wired network with a crossover cable
Laptop: - Dell latitude - Ubuntu 9.10 - Connected to "Dektop" via wired network with a crossover cable
The wired connection is working, both computers are able to ping each other, but I haven't managed to share internet, nor files. I have tried many different ways, from setting the wired network to "Shared to other computers" to this guide in the Ubuntu Wiki. The best I could get was for the connection to work by setting the IPs manually, whatever else I try results in either nothing or in a not-working connection.
I've been reading around, but not had much success at all in trying to share the internet connection from my laptop to my phone.all the articles i read refer to earlier versions of Ubuntu and the packages they mention have become obsolete, according to the apt-get tool.im not that new to Linux, but my networking probably isn't up to scratch.if anyone could help me, that would be great, im using Ubuntu 10.04 at the time of writing.
I am in college and live in a dorm room. As a dorm resident, I have access to only one wired network connection and I am not allowed to connect it to a router. My primary computer is multihomed and I was hoping I could share network access (eth1) through eth0 to a router. Then I want to hook up my secondary system to the router. I am not using the WAN port on the router. I believe this makes it act like a switch, which seems to be what I want.Here is my /etc/network/interfaces file on my primary computer
Code: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).
