Installing the Software
4-12
6) Still as root, use the following commands to make the NFS server
aware of the change to its configuration and to invoke an NFS restart.
host $ /usr/sbin/exportfs -av
host $ /sbin/service nfs restart
Note: Use
exportfs -rav
to re-export all directories. Use
/etc/init.d/nfs status
to verify that the NFS status is running.
7) Verify that the server firewall is turned off:
host $ /etc/init.d/iptables status
If the firewall is running, disable it:
host $ /etc/init.d/iptables stop
4.3.8 Testing the Shared File System
To test your NFS setup, follow these steps:
1) Get the IP address of your host Linux workstations as follows. Look
for the IP address associated with the eth0 Ethernet port.
host $ /sbin/ifconfig
2) Open a terminal emulation window to connect to the EVM board via
RS-232 using the instructions in Section 2.2. If you have a Windows
workstation, you can use HyperTerminal. If you have a Linux
workstation, you might use Minicom. (You may need to turn on line
wrap.)
3) Power on the EVM board, and abort the automatic boot sequence by
pressing a key in the console window (Section 2.2).
4) Set the following environment variables in the console window:
EVM # setenv nfshost < ip address of nfs host >
EVM # setenv rootpath < directory to mount >
EVM # setenv bootargs console=ttyS0,115200n8 noinitrd rw
ip=dhcp root=/dev/nfs
nfsroot=$(nfshost):$(rootpath),nolock mem=120M
davincihd_capture.channel0_numbuffers=4
Note that the
setenv bootargs
command should be typed on a
single line. Also note that you should avoid using the numeric keypad
to enter numbers, as it can sometimes insert extra invisible
characters.
The
< directory to mount >
must match what you specified in Step
5 of Section 4.3.7. For example, /home/< useracct >/workdir/filesys.
