Three aspects of building a tftp server

The problem of tftp server is also involved in the previous article. Here we will mainly explain how to build a tftp server. We have summarized three aspects for your reference, so I hope that some of the conclusions in this article will be helpful to you.

Build a tftp server 1. First find the tftp server package from the fedora disc, copy it, and install it.

Build a tftp server 2. Modify the/etc/xinetd. d/tftp file as follows:

 
 

  
  
service tftp  
  
  
 
  
  
{  
  
  
        socket_type             = dgram 
  
  
        protocol                = udp 
  
  
        wait                    = yes 
  
  
        user                    = root 
  
  
        server                  = /usr/sbin/in.tftpd  
  
  
        server_args             = -s /tftpboot  
  
  
        disable                 = no 
  
  
        per_source              = 11 
  
  
        cps                     = 100 2  
  
  
        flags                   = IPv4 
  
  
} 
 
 

There are also the following:

 
 

  
  
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 
  
  
} 
 
 

Note: The Modification Item server_args =-s <path>-c, where <path> can be changed to the root directory of your tftp-server, and the parameter-s specifies the chroot, -c specifies that files can be created.

Build a tftp Server 3. Start tftp

 
 

  
  
service xinetd restart 
 
 

In this case, the startup should be successful, as shown in the following test:

 
 

  
  
#tftp     your-ip-address  
  
  
tftp>get <download file> 
  
  
tftp>put <upload file> 
  
  
tftp>q  
  
  
# 
 
 

During this process, pay attention to whether the firewall is disabled.

Question 1:

After tftp is installed, a file is generated under tftpboot, and then tftp 192. xx

 
 

  
  
tftp> get test  
  
  
 
  
  
Error code 0: Permission denied 
 
 

This problem occurs when the permission of the generated file is incorrect. You can modify the permission of the test file, chmod 777 test, and then test again and pass the test.
