Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have gone back and implemented your suggestions, which I
was in the process of doing earlier.
However, when I attempt to mount the server directory on
the client, I get an error.
e.g. if I type
mount -t nfs svr_name:/svr_directory /client_dir
mount: svr_name:svr_directory failed, reason given by server: Permission denied.
The /etc/exports file on the server lists the svr_directory
with read-only access by IP address, e.g.
rpc.mount and nfsd show in a px aux list.
I still think my problem is that the kernel on the client and the server do not list nfs in cat /proc/filesystems.
Both the O'Reilly Network Admin Guide and the NFS HOWTO state
that the kernel needs nfs support and use the
cat /proc/filesystems command for determining if it is there.
Also, on both machines, ipchains -L shows
Chain input (policy ACCEPT):
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):
I have read that firewalling sometimes interferes with nfs
so I opened it up.
I have also run exportfs -a -v on the server and it
acknowledges reexporting the directories to the kernel.
I guess what puzzles me is why it would say that if the
cat /proc/filesystems does not list nfs.
I put a bunch of "echo .... " > /tmp/nfs-start.out
statements in the nfs startup file.
Uses /etc/rc.d/init.d/nfs in RH.
Apparently the client also wants an /etc/exports file.
I thought the server needed the /etc/exports file to see
which directories it could export when someone did a
mount -t nfs server:/nfsdir
from the client. What is the client doing with it?
I'm not sure what the client is using /etc/exports for in
this case since all it has in it (on the client) is
service start nfs
will fail if /etc/exports is not there.
It also has to be > 0 bytes.
Right now I have two machines with an nfs directory
mounted from the other (not the same ones) and all
seems to be OK.
Thanks for your help. I have about 10 years of Unix,
(and not much networking) but only 6 months of Linux so
a lot of this is new. Now on to NIS.
The client doesn't need to run any nfsd processes, just the server. The reason you are having to create a /etc/exports file is because you are starting up an nfs server on the client... the server looks for /etc/exports.
I can't remember what daemons the client needs other than portmap... even rpc.mountd is only needed by the server.
