Issue

I am following this tutorial to work with tftp:

First, I install all the necessary packages:

sudo apt-get install xinetd tftpd tftp -y

Next, create a configuration file:

sudo nano /etc/xinetd.d/tftp

Put the following content into the file.

service tftp
{
   protocol = udp
   port = 69
   socket_type = dgram
   wait = yes
   user = nobody
   server = /usr/sbin/in.tftpd
   server_args = var/lib/tftpboot -s
   disable = no
}

Now I change the ownership of the directory:

sudo mkdir /var/lib/tftpboot
sudo chown -R nobody:nobody /var/lib/tftpboot
sudo chmod -R 777 /var/lib/tftpboot

and start the TFTP service:

sudo service xinetd stop
sudo service xinetd start

Then verify the TFTP is running correctly or not:

    root@ravi-Inspiron-N5010:/home/ravi# netstat -na | grep LIST | grep 69
unix  2      [ ACC ]     STREAM     LISTENING     16171    @/com/ubuntu/upstart-session/1000/1692
root@ravi-Inspiron-N5010:/home/ravi# 

The output of the netstat is different from what is mentioned in the tutorial:

tcp        0      0 0.0.0.0:69              0.0.0.0:*     LISTEN

Please help me in correctly starting the tftp.
