Some people had some problems using NFS (threads are there). We mostly managed to solve them by using the kernel based NFS server and not the user space based one. As I am still on openSUSE 10.3 there may be small differences.
First the server:
Uninstall nfs-server, if it is installed, using YaST > Software > Software Management.
Install the following packages if they are not allready installed: nfs-kernel-server and yast2-nfs-server (install yast2-nfs-client also, it makes YaST know about the whole of NFS) using YaST > Software > Software Management.
Use YaST > System > System Services (Runlevel) to Enable nfsserver.
You are now ready to specify what you want to export/share. SunOS (Solaris to many people) indeed has a share program that interfaces to the configuration. Linux has not, but openSUSE has YaST.
YaST > Network Services > NFS Server. Here it is also possible to switch the service on/off. It must be in the status Start. After clicking Next you can enter the directory you want to export and the sytem(s) that you will allow as clients fort this directory (security). Also options (like rw) can be entered here. Finish and ready.
Look in /etc/exports for the results. Of course it is not needed to use YaST. You can edit /etc/exports directly (and see man exports for the documentation.
exports the directory /home/wij read/write to the system beneden.henm.nl.
You may also be interested in reading man exportfs.
Then the client.
The products nfs-client and yast2-nfs-client must be installed (the YaST modules are only needed when you work through YaST).
Use YaST > Network Services > NFS Client to make the mount instructions (YaST will edit /etc/fstab and do the mount) or edit /etc/fstab yourself and call mount. Or even do a mount with all the parameters needed. An entry in /etc/fstab could look like
to mount the directory exported above.
boven.henm.xs4all.nl:/home/wij /home/wij nfs defaults 0 0
Hope this helps.
