There are many ways to connect your Nokia Internet Tablet to your Linux PC, just to mention the top 3:

USB: cable direct connect: (You should see your NIT as a storage device, much like a USB drive)

WiFi: You could access services on your Linux PC from your NIT via a local wireless (WiFi) network. For instance you could install OpenSSH on your Nokia Internet Tablet. Then open a terminal shell on the NIT and try to open an ssh connection to your linux computer.

Bluetooth: you could establish a Bluetooth radio connection between your NIT and your Linux PC and for instance: exchange files.

Each one of these types of connections requires some type of configuration (and requirements) either on the NIT, or on your Linux PC or most probably, on both.

If you could describe how you "connect" your NIT to your Linux PC and, what happens next (or not, or what you expected to happen). Then we all could have a better idea on how to guide you achieve that connectivity between your Nokia and your Linux PC.

I do have a Linux PC (Fedora distribution) and have total connectivity betwwen this machine and my Nokia N810.

Kind regards.
