TFTP: server says: file not found solution

Under Linux, regardless of which super-Server, inetd, or xinetd is used, the TFTP service is disabled by default, so modify the file to open the service.
According to the installation method of (1), the file /etc/xinetd.d/ TFTP can be modified. It is mainly to set the root directory of the TFTP server and start the service. The modified file is as follows:
service tftp
{socket_type = dgram
Protocol = udp
Wait = yes
User = root
Server =/usr/sbin/in TFTPD
Server_args = -s/home/LQM/tftpboot – c
Disable = no
Per_source = 11
The CPS = 100 2
Flags = IPv4
Server_args = -s < server_args= -s < path> -c, where < path> Change to the root directory of your TFTP-server. The parameter -s specifies chroot and -c specifies that files can be created.
3. Create TFTP root directory and start TFTP-Server.
#mkdir /home/lqm/tftpboot
# chmod o + w/home/LQM/tftpboot
#service xinetd restart
Stop xinetd: [sure]
start xinetd: [sure]
At this point, TFTP-Server is started. You can log in to test the following commands:
# TFTP & lt; your-ip-address>
tftp> get < download file>
tftp> put < upload file>
tftp> q

installation process problems and causes
