Whether you're setting up for broadband Internet access at home, or for regular network use in a business environment, network setup gets done automatically when you install Ubuntu. By default, your computer will get set up to act as a DHCP client, which means that it will automatically be assigned an Internet Protocol address whenever you boot it up.

Wireless Setup

There have been a lot of changes in wireless and a great deal of work has gone into Ubuntu Gutsy Gibbon to aid wireless connections. This tutorial will help you with a few of the wireless issues with Ubuntu Gutsy Gibbon. We will attempt to install 3 different network cards on a Lenovo T60p.

Network Troubleshooting

There are tabs on the Network Tool window are for utilities that help you analyze or troubleshoot your network.

Using Netstat

Under the Netstat tab, you can take a look at routing table information. This can help you out if you have trouble connecting to either the Internet, or to other segments of your Local Area Network.

Network Security

Use the Port Scan utility to help identify security holes on other computers. As you can see, we have quite a few open ports on this particular computer. You can now verify which of these ports that you really need open, and re-configure that computer's firewall accordingly.

Access Shared Folders

There are other ways to share files with family or co-workers. If you have nothing but Linux computers on your network, then you can use the Network File System, or NFS. If you have a mixed-operating system environment, with both Linux and Windows computers on your network, then you can use Samba. Either way, you'll be able to access a shared folder on another computer by just double-clicking on an icon in your graphical file manager.
