5.4 Configuring NFS Service
If you have installed Fedora9 on your system, all the corresponding NFS components will be
installed by default, you can just follow the steps below to setup and configure the NFS service.
5.4.1 Setting up Shared Directories
Note: to access a shared directory, you need to follow what were described in 5.4.2 to install the
root_qtopia system.
(1) Set up Shared Directories
Run the command below:
#gedit /etc/exports
This command edits the NFS configuration file. Add the following line (Note ： if this file is
opened for the first time, it will be empty):
/opt/FriendlyARM/MINI2440/root_qtopia *(rw,sync,no_root_squash)
“/opt/FriendlyARM/mini2440/root_qtopia” is a NFS shared directory, it can be mounted as
the root file system through NFS;
* means all clients can mount to this directory.
rw means all clients that have been mounted to this directory have the read and write rights
to this directory.
no_root_squash means all clients that have been mounted to this directory can be set to a
root user.
5.5.2 Starting NFS
You can start the NFS service through either command line or graphic interface. We set up the
NFS service to let others access shared directories. By default Fedora starts it firewall which will
disable the NFS service. So you need to disable the firewall by typing “lokkit” in a command line
window.
