1. Virtual Machine installed tftp server.
##########################
the TFTP Server the Install and Setup
the Install Packages Standard Package following.
sudo apt-get install xinetd tftpd tftp
Create /etc/xinetd.d/tftp and put this entry
service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /tftpboot
disable = no
}
Create a folder /tftpboot this should match whatever you gave in server_args. mostly it will be tftpboot
sudo mkdir /tftpboot
sudo chmod -R 777 /tftpboot
sudo chown -R nobody /tftpboot
Restart the xinetd service.
newer systems:
sudo service xinetd restart
older systems:
sudo /etc/init.d/xinetd restart
Now our tftp server is up and running.
Testing our tftp server
Create a file named test with some content in /tftpboot path of the tftp server
Obtain the ip address of the tftp server using ifconfig command
Now in some other system follow the following steps.
tftp 192.168.1.2
tftp> get test
Sent 159 bytes in 0.0 seconds
tftp> quit
cat test

1-2. Installing the server NAS
nfs service is file sharing between Linux and Linux, nfs services building easier.
Now how to set up nfs service ubuntu16.04 system, ubuntu is even simpler to build than Red Hat.
1, installation services nfs
the sudo APT the install nfs-Kernel-Server
the sudo the install nfs-Common APT
2, modify the configuration file
sudo vim / etc / exports
the content is as follows:
/ * Home (RW, Sync, the no_root_squash)
#OR / Home / Andrew / w
mean expression paragraphs below, the actual modification
/ home: * shared directory: specify which users can access all of ping * 10.67 * * specify the network segment, the segment with the user's host. users can mount 10.67.112.183 only the user can mount
(ro, sync, no_root_squash): permissions
ro: read only
rw: read-write
sync: synchronize
no_root_squash: not reduce the root user's permissions to view other options man 5 exports
3, restart nfs service
sudo /etc/init.d/nfs-kernel-server restart
This, nfs services to build better.
The following describes how a client accesses the server
1, the client and the server checks whether the network connectivity (ping command)
the ping + host IP
2, view server shared directory
showmount -e + Host IP
showmount -e 10.67.112.183
Export List for 10.67. 112.183:
/ Home *
3, the local directory is mounted to
Mount 10.67.112.183:/home / mnt
4, access
access to local mnt directory, you can access the shared directory of the server.

2. Reference 'Hi3519AV100 SDK installation and upgrade instructions .pdf' -> 2.1.2 Procedure -> Step 1. tftp server
to put related files '/ tftpboot' folder below
3. Set the virtual machine used in bridge mode, a common computer access. Configure the virtual machine to a fixed ip (such as 192.168.0.100), maintaining the same network segment with the computer.
Now assume that computer ip is 192.168.0.200
