NFS HOWTO: README.first Next Previous Contents

2. README.first

NFS, the Network File System has three important characteristics:

It makes sharing of files over a network possible.

It mostly works well enough.

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 security section of this HOWTO, and you will be vulnerable to fewer silly security risks. 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 ;-)

There are two sections to help you troubleshoot NFS, called Mount Checklist and FAQs. Please refer to them if something dosen't work as advertized.

The home-site for the Linux 2.0 nfsd is ftp.mathematik.th-darmstadt.de:/pub/linux/okir, in case you want/need to get it and compile it yourself.

For information about NFS under Linux 2.2 please see the Linux 2.2 section.
