NFS, the Network File System has two important characteristics:

• It makes sharing of files over a network possible.
• It opens a can of security risks that are well understood by crackers, and easily exploited to get access (read, write and delete) to all your files.

I'll say something on both issues in this HOWTO. Please make sure you read the whole of this HOWTO, and you will be vulnerable to fewer silly security risks. Don't say I didn't warn you. The passages about security will at times be pretty technical and require some knowledge about IP networking and the terms used. If you don't recognize the terms you can either go back and check the networking HOWTO, wing it, or get a book about TCP/IP network administration to familiarize yourself with TCP/IP. That's a good idea anyway if you're administrating UNIX/Linux machines. A very good book on the subject is TCP/IP Network Administration by Craig Hunt, published by O'Reilly & Associates, Inc. And after you've read it and understood it you'll have higher value on the job market, you can't loose ;-)
