Changing path for destination of file after using put command in tftp

Question

I am using two linux machines to do tftp file transfer. The transfer is happening properly if server_args path is /var/lib/tftpboot(default path). But when i change it to some other path for eg(/home/user/dir), the put command does not work. So for configuring a path for destination what is the way. Thanks

I believe this will do with permissions on the directory and who can write to them. If you run ls -al /var/lib | grep tftpboot, take a look at the permissions (probably drwxrwxrwx) as well as the owner of the directory. Then, look at the /home/user permissions and you'll see that it will be set to drwx------ which means that only the user who owns that directory can write to it - tftpd won't have permissions to write to that directory. If you're using Ubuntu, see here for how to properly configure the destination directory for tftpd especially the part about chown.

Edit: SELinux needed to be disabled (or configured) for tftp to write to the specified directory (/home/tftpd in this instance).
