Question
Getting NFS right..
I am trying to set up NFS. But it's not working correctly.
This is my /etc/exports:
/home/SDB1 192.168.1.100(ro,async,no_
/home/Sources 192.168.1.100(ro,async,no_
This is my /etc/fstab at the client:
192.168.1.102:/home/SDB1 /home/NFS1 nfs defaults 0 0
192.168.1.102:/home/Source
Also tried:
mount -t nfs -o defaults 192.168.1.102:/home/Source
I get the error:
mount: wrong fs type, bad option, bad superblock on 192.168.1.102:/home/Source
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
All firewalls are taken down, there are read rights for everyone on the share point and down the tree. Portmaps, nfs-common and nfs-kernel-server is installed. Nfs has been restarted after /etc/exports edit, without errors.

What distribution of Linux are you running? Are you sure you have the utilities/kernel module to mount NFS shares? In Ubuntu/Debian I believe the package is nfs-common - ie: apt-get install nfs-common.
Have you checked the logs on the NFS server? If it were a permission problem in your exports file you would see something like:
"failed, reason given by server: Permission denied" on the client
and something like:
"refused mount request" on the server
I forgot to install nfs on the client :) (but it was all installed and ready on the server)
At the end of the installation, the system tries to start netatalk but fails:
Starting Netatalk services (this will take a while): nbp_rgstr: Connection went over timelimit
Can't register Deb-i86a:Workstation@*
I then try:
Deb-i86a:~# mount -t nfs -o ro 192.168.1.102:/home/Source
mount.nfs: 192.168.1.102:/home/Source
All the other setup is done as suggested by the experts in this thread.
Logs on the client:
user.log:Nov 7 19:04:17 Deb-i86a if-up.d/mountnfs[eth7]: if-up.d/mountnfs[eth7]: lock /var/run/network/mountnfs exist, not mounting

syslog:Nov 7 19:04:17 Deb-i86a if-up.d/mountnfs[eth4]: if-up.d/mountnfs[eth4]: lock /var/run/network/mountnfs exist, not mounting

syslog:Nov 7 19:06:30 Deb-i86a nfsd[3197]: nfssvc: Input/output error
Logs on the server:
Nothing special.
The client runs Debian GNU/Linux 5.0 \n \l with 256 Mb memory as a virtual machine in terminal text based mode only. No GUI.
I'm not 100% sure about what georgekraj posted - I've always put a subnet mask on my Linux exports declarations if I wanted to open it up to a subnet. This behavior could be different across different platforms - ie: solaris, linux, etc. ie:
/home/SDB1 192.168.1.0/24(ro,async,no
/home/Sources 192.168.1.0/24(ro,async,no
What is the server running? If it's Debian/Ubuntu look at /var/log/daemon.log - if the client is getting a permission denied error somewhere on the server the mount request should be logged
To get things to work, I;
*installed nfs on the client also
*allowed the whole subnet to connect, whe exporting the filesystem vi /etc/exports. Hence:
/home/Sources 192.168.1.0/24(ro,async,no
*mounted the share on the client as read only and nolock. If I tried to mount it just with read only, I got this error:
mount.nfs: rpc.statd is not running but is required for remote locking.
Either use '-o nolock' to keep locks local, or start statd.
Please comment further if you wish.

You're exporting filesystems as ro, but trying to mount them as rw.
Try mount -t nfs -o ro 192.168.1.102:/home/Source
