    【背景】

    折腾：

    【记录】尝试用QEMU模拟ARM开发板去加载并运行Uboot，kernel，rootfs

    期间，需要在Ubuntu下为QEMU安装一个Open TFTP Server。

    【折腾过程】

    1.去参考教程：

    Virtual Development Board

    下载

    http://cdnetworks-kr-1.dl.sourceforge.net/project/tftp-server/tftp%20server%20multithreaded/opentftpmtV1.63.tar.gz

    2.然后去找到sourceforge的地址（注意是multithreaded）：

    http://sourceforge.net/projects/tftp-server/files/tftp%20server%20multithreaded/

    去下载对应的：

    opentftpmtV1.65.tar.gz

    得到后，解压：

    crifan@ubuntu:opentftp$ cd opentftp/

    LICENSE  opentftpd  opentftpd.cpp  opentftpd.h  opentftp.ini  rc.opentftp  README

    3.然后移动到opt下：

    LICENSE  opentftpd  opentftpd.cpp  opentftpd.h  opentftp.ini  rc.opentftp  README

    #listening on ports less than 1024 needs root account to
    #start the server but can switch to another user while
    #running (please see username under [TFTP-OPTIONS] section.
    #You can also listen on 0.0.0.0, which will amount to
    #listening on all interfaces on single socket. If you do
    #not specify any interface, it will automatically detect
    #all interfaces.and would listen individually on these

    #files, this user should have read access to the files.
    'username=myname
     
    #Next option is server port range on which tftpserver
    #would respond from, if you have firewall
    #issues, you may like to restrict this
    #range. default is any free port
    #do not use reserve ports less than 1024

    #requests on port 69 but responds on any free

    7.所以，去试试，直接修改/etc/rc.local：

    改为：

    ?
    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11

    16
    17
    #!/bin/sh -e
    #
    # rc.local
    #
    # This script is executed at the end of each multiuser runlevel.
    # Make sure that the script will "exit 0" on success or any other
    # value on error.
    #
    # In order to enable or disable this script just change the execution
    # bits.
    #
    # By default this script does nothing.
     
    /opt/opentftp/rc.opentftp start
    /opt/opentftp/rc.opentftp status
     
    exit 0

    然后重启Ubuntu去试试是否可以自动运行此tftp。

    结果是可以的：

    Open TFTP Server is running - Pid : 1515
    crifan@ubuntu:Desktop$

    如图：

    check opentftp status running ok

    【总结】

    此处，只是下载合适的tftpopen，并且加到启动项里面。即可。
