Configuration of tftp Server

We have also explained how to configure the tftp server. Here we will mainly explain how to configure the tftp server in Ubuntu. We have summarized the specific steps and hope to help you.

Configure the tftp Server 1. Open the Ubuntu terminal and enter the following command:

 
 

  
  
sudo apt-get install tftpd-hpa tftp-hpa 
 
 

Configure tftp Server 2. Delete standalone Startup Mode

 
 

  
  
update-rc.d -f tftpd-hpa remove 
 
 

Configure the tftp Server 3. Create the user tftpd and its home directory

 
 

  
  
Sudo mkdir-p/home/tftpd
  
  
Sudo useradd-s/bin/false-g nogroup-d/home/tftpd [-p PASSWORD] tftpd
  
  
Example: sudo useradd-s/bin/false-g nogroup-d/home/tftpd
  
  
Add password: sudo useradd-s/bin/false-g nogroup-d/home/tftpd-p 123456
  
  
3.5 install xinetd
Sudo apt-get install xinetd
 
 

Configure the tftp Server 4. Create the xinetd Startup File

 
 

  
  
Cat/etc/xinetd. d/tftpd
  
  
Service tftp
  
  
{
  
  
Disable = no
  
  
Socket_type = dgram
  
  
Wait = no
  
  
User = root
  
  
Protocol = udp
  
  
Server =/usr/sbin/in. tftpd
  
  
Server_args =-s/home/tftpd-p-c-U 077-u tftpd # // indicates that the tftp operation directory is on/home/tftpd.
  
  
Log_on_success = PID HOST DURATION
  
  
Log_on_failure = HOST
  
  
}
 
 

Configure tftp Server 5. comment out the/etc/inetd. conf file to start tftpd

 
 

  
  
#tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot  
  
  
5.5 if you have other network connections, such as WiFi, dual-eth cards, pls shutdown the others if tftp is not working. 
 
 

Configure the tftp Server 6 and restart the xinetd service

 
 

  
  
sudo /etc/init.d/xinetd restart 
 
 

Configure the tftp Server 7. test whether the tftpd service is successful

 
 

  
  
tftp localhost  
  
  
tftp> put 123.log  
  
  
tftp> put 123.log test.log  
  
  
tftp> get test.log  
  
  
tftp> get test.log abc.log  
  
  
tftp> verbose  
  
  
Verbose mode on.  
  
  
tftp> trace  
  
  
Packet tracing on.  
  
  
tftp> put kkk.log  
  
  
sent DATA  
  
  
received ACK  
  
  
.........  
  
  
sent DATA  
  
  
received ACK  
  
  
Sent 12999997 bytes in -1.5 seconds [-69987938 bit/s] 
 
 

Note: In which directory is the tftp Command executed, the uploaded files are all files under this directory, and the downloaded files can only be those files under the server directory! Because the evb board is connected to the USB 0 Nic under Liunx, set the address of the USB 0 Nic. ifconfig to see if there is a nic, then sudo ifconfig usb0 192.168.100.1 because the default blob address server address is 192.168.100.1, you need to set it like this. Ps: if tftp is unavailable in Ubuntu, it must be a problem with the server. Run sudo/etc/init. d/xinetd restart again in liunx. You can use tftp localhost to test whether the server of the host can transmit data.
