Use of serial port tools under linux and network connection development board

Check if the serial port is connected, you can use

ls /dev/tty
然后按TAB键

or

dmesg | grep tty

If connected, there is a  ttyUSBXX

====================================================================

 

Serial port tool: minicom

installation: 

apt-get install minicom

Configuration:

sudo minicom -s

After entering, the third change the baud rate and name

Save:

run:

sudo minicom

Has entered the board system

====================================================================

NFS mount

Install server on the computer first

sudo apt-get install nfs-kernel-server

Modify the configuration file:

sudo vim /etc/exports

Make the following configuration:

/media/modian/D/sigmastart_share 192.168.117.*(rw,sync,no_root_squash)

The first path is the path you want to mount in the past

The ip behind is the ip of the board (check with ifconfig on the board)

 

After configuration, restart the NFS service:

sudo /etc/init.d/nfs-kernel-server restart 

 

Then you can try to ping the board and the host to see if it works

In the development board input:

mount -n -o nolock 192.168.0.12:/media/modian/D/sigmastart_share /mnt/

The ip in front is the ip of the computer

The first path is the path of the computer, which is synchronized with the previous configuration

The second is the path where it is mounted

 

OK!!!!!!!!!!!!!!!!!!!

===============================================

Did you find that the IP has changed every time you restart the board, and you have to mount it, which can be written in the boot command:

vi /etc/init.d/rcS

The usage is the same as vim

Write inside:

The first is to change the ip and subnet mask

The second is to mount

 

====================================================================

Scan LAN IP:

arp

===========================

telnet connection:

The serial port is too troublesome, use a network cable

sudo apt-get install openbsd-inetd
sudo apt-get install telnetd
sudo /etc/init.d/openbsd-inetd restart
# 查看 telnet服务是否开启
sudo netstat -a | grep telnet

 

telnet login

telnet 192.168.x.x
