Windows and Linux file sharing

Okay so I have a little computer that is running Fedora Core. I have a few questions about it.

1. How do I change the network identity of it? ie) the computer name.

2. How do I find out what the ip address is for the computer? ie) In windows I can use the console and run ipconfig and it will return my lan ip.

Try ifconfig -u for the IP address.
hostname -s to reset the hostname

Those are Unix commands. They might work with Linux

in Fedora, run: /sbin/ifconfig
and it will display information on your running network interfaces. the inet-addr is your local ip.
you can change your network identity in the file /etc/hosts or you can run the command: hostname -v desiredHostname
the hostname changes must be made with root privileges.
