Great info, is there anything that needs to be done to the computer receiving the shared internet?

My small home network is configured on windows and is broadcasting on a second router. The internet connection works on other computers (windows / mac) but I can’t connect from Ubuntu 11.04. I can see the name of the network in the network manager, can connect in “Local-only” mode, but cannot get any data from the internet…

maybe i should upgrade??

I have a question. I have an ADSL connection going to router, and from router via cable to my laptop. No WiFi enabled. Can I connect my Blackberry to the internet via my laptop? I mean could I create some wifi network on/from my laptop that my BB could connect to ?

When attempting to follow your method I receive the following:
root@trevorj-Linux:/home/trevorj# apt-get install dnsmasq ipmasq
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package ipmasq is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘ipmasq’ has no installation candidate

can you help?

@Neel,

it might be different smtp settings. On evolution mail, if youre isp is different from office unto your house probably it uses different smtp. check your isp provider or contact them for the smtp address, and if the allowed smtp port connection.

I have already set up my internet on my Ubuntu 10.10. I have two internet connections, one at the office and one at home. Now when I try opening youtube-dl, Evolution mail, gpg sever key download from home it doesnt get downloaded and says ‘Connection Timed out’. However at my office premises all the above programs work like a charm.
P.S. I have two different speed connections at home and office. Also two different kinds of Modems. All other sites opening and downloads work like a charm on both the connections.
Kindly suggest what could be the possible solution.

I have installed Ubuntu before on this PC w/o even needing to configure my wireless connection but now I can’t get it to connect except for sometimes it will connect for 20 seconds or so. Any ideas what I need to change. I’ve tried configuring a static IP like I have to do on all my crummy windows machines but even that didn’t work. I can’t ping anything. What is the deal?

Hi, this is for setting up the gateway right. Can someone help in configuring the client?

Wierd..you say the following code twice:

Start by configuring the network card that interfaces to the other computers on you network

# ifconfig ethX ip

where ethX is the network card and ip is your desired server ip address (Usually 192.168.0.1 is used)

Then configure the NAT as follows

# iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE

where ethX is the network card that the Internet is coming from

# echo 1 > /proc/sys/net/ipv4/ip_forward

I have followed these instructions and the Ubuntu one’s and have tried firestarter. I am trying to do the network as follows:

ISP >> router >>> ||| ETH0 >>> Ubuntu 9.04 >>> ETH1 ||| >>> Windows 2000 machine.

The windows 2000 machine will not detect any internet connection. I have made my own crossover cable and I think it is working correctly because both network adapters’ lights are lit and blink occasionally. What could be wrong? I can’t find the tcp/ip settings in win2000. I don’t know much about Windows… It’s the most confusing operating system I’ve used!

erm… hi, I just wanna know how to set up my network, I have a USB Modem connected to my host, and the host is connected (with wire and sometimes i have to unplug and connect wirelessly) to a router that broadcasts the network.

i have no problem setting up the network when the router is connected by lan cable [just set up the IPv4 numbers manually, choose my host IP to be same as gateway and same as DNS, while the USB modem has its own external DNS servers to get the internet], but i’m trying to find out how to do it if the host was connected wirelessly to the router, it doesn’t seem to work the normal way.

thanks

A big thanks, that was helpful!!!
It works now!!!

I am also new to ubuntu but now I am sharing my internet from ubuntu to windows vista!
After i have followed these steps i tried from Vista to get automatically ip (DHCP) but did not work so i set the ip manually, for instance 192.168.0.2. It just took me a minute!!!

Thanks again!!!
