$ export PATH=/opt/toolchain/2009-q1/bin:$PATH $ export PATH=/opt/u-boot/tools:$PATH
TFTPD
step 1
install the package and find the directory
$ sudo apt-get install xinetd tftpd tftp $ sudo mkdir /home/test/tftpboot $ sudo chmod -R 777 /home/test/tftpboot $ sudo chown -R nobody /home/test/tftpboot
step 2
copy the uimage to the folder
sudo cp uimage $tftproot
step 3
create the file /etc/xinetd.d/tftp
$ sudo vim /etc/xinetd.d/tftp
service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /home/test/tftpboot
disable = no
}
step 4
start and stop the tftp server
sudo /etc/init.d/xinetd stop sudo /etc/init.d/xinetd start
step 5
test
$ ifconfig > /home/renee/test/test.txt
$ tftp 127.0.0.1
tftp> get text.txt

tftpd-hpa
sudo apt-get install tftpd-hpa sudo apt-get install tftp-hpa # client
sudo vim /etc/default/tftpd-hpa #将原来的内容改为: TFTP_USERNAME="tftp" TFTP_ADDRESS="0.0.0.0:69" TFTP_DIRECTORY="tftp根目录" #服务器目录,需要设置权限为777,chomd 777 TFTP_OPTIONS="-l -c -s"
sudo service tftpd-hpa restart
NFS
step 1
find the location
dst="${HOME}/targetfs" mkdir -p $dst
step 2
extract the filesystem
me='whoami' #if exist the old filesystem, then sudo rm -rf $dst sudo tar xzf xxx.tar.gz -C $dst sudo chown $me:$me $dst sudo chown -R $me:$me $dst/home $dst/usr $dst/etc $dst/lib $dst/opt $dst/boot
step 3
export the target filesystem for NFS access
sudo chmod 666 /etc/exports
sudo echo "$dst *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)" >> /etc/exports
sudo chmod 644 /etc/exports
step 4
start and stop the NFS server
sudo /etc/init.d/nfs-kernel-server stop sudo /etc/init.d/nfs-kernel-server start
