ubuntu中配置tftp服务(自己已经测试过)

sudo apt-get install tftpd-hpa tftp-hpa
打开/etc/default/tftpd-hpa
#Defaults for tftpd-hpa
RUN_DAEMON="no"
OPTIONS="-l -s /var/lib/tftpboot"
修改设置如下：
#Defaults for tftpd-hpa
RUN_DAEMON="yes"
OPTIONS="-l -s /home/zdreamx/tftpboot"
其中/home/zdreamx/tftpboot是自己设定的目录，可以根据情况修改。

选项参考
OPTIONS
-l Run the server in standalone (listen) mode, rather than run from
inetd. In listen mode, the -t option is ignored, and the -a
option can be used to specify a specific local address or port
to listen to.

-a [address][:port]
Specify a specific address and port to listen to when called
with the -l option. The default is to listen to the tftp port
specified in /etc/services on all local addresses.
listen 的 ip address 和 Port
-c Allow new files to be created. By default, tftpd will only
allow upload of files that already exist. Files are created
with default permissions allowing anyone to read or write them,
unless the -p or -U options are specified.

-s (决定tftp根目录)Change root directory on startup. This means the remote host
does not need to pass along the directory as part of the trans-
fer, and may add security. When -s is specified, exactly one
directory should be specified on the command line. The use of
this option is recommended for security as well as compatibility
with some boot ROMs which cannot be easily made to include a
directory name in its request.
