Under Linux, the TFTP service is disabled by default, regardless of which super-server,inetd or xinetd is used, so modify the file to open the service.

Depending on the installation method (1), the file/etc/xinetd.d/tftp can be modified. The main is to set the root directory of the TFTP server to open 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

CPS = 100 2

Flags =ipv4

}

Description: Modify the item server_args=-S <path>-C, where <path> can be changed to the root of your tftp-server, parameter-s specifies that chroot,-c specifies that the file can be created.

3. Create the TFTP root directory and start Tftp-server.

#mkdir/home/lqm/tftpboot

#chmod O+w/home/lqm/tftpboot

#service xinetd Restart

Stop xinetd: [OK]
Start xinetd: [OK]

In this way, the Tftp-server is started. You can log in to this machine to test the following, command as follows:

#tftp <your-ip-address>

Tftp>get <download file>

Tftp>put <upload file>

Tftp>q

#

problems and causes during installation
Phenomenon One:
Tftp> Get Test.log
Transfer timed out.
Reason:
TFTPD Service not started

Phenomenon II
Tftp> put Test2
Error Code 0:permission denied

Reason:
Run the command to view the system log
#tail/var/log/messages
The following text is found:
Mar 19:05:26 localhost setroubleshoot:selinux is preventing/usr/sbin/in.tftpd (tftpd_t) "Write" to Tftpboot (TFT      pdir_t). For complete SELinux messages. Run Sealert-l 40a5a6bf-8ded-4bfa-ab6e-fa669a25fc6c
Know this is caused by selinux, in FC3 and FC3 after the FC version of the SELinux default is open, now turn it off, modify the file/etc/sysconfig/selinux, set the

Selinux=disabled

Then restart your computer to

or execute the command System-config-securitylevel open the Security Level Configuration dialog box to change the SELinux (S) option to "Allow" in "force".

Phenomenon Three:
Tftp> put Ex070416.log
Error Code 1:file not found
Reason:
The specified file does not exist, or the-C option is not specified in the TFTPD startup parameter, allowing the file to be uploaded

Phenomenon Four:
Tftp> Get Test.log
Error Code 2:only Absolute filenames allowed
Reason:
The Server_args set in/ETC/XINETD.D/TFTPD is/ETC/DEFAULT/TFTPD-HPA
Cat/etc/default/tftpd-hpa
#Defaults for TFTPD-HPA
Run_daemon= "No"
options= "-s/home/tftpd-c-p-u 077-u tftpd"
When set, just change the server_args= to the server folder you set yourself.
