大家对深山红叶，矮人DOS工具箱之类的维护光盘应该不陌生了，作为企业，网吧网管，随手准备这样的光盘真的是能解决很多问题。对于网刻，相信很多人也有所了解。但是，在网吧/公司维护机器时。基本上面对的都是无光驱的机器，如果要用这些工具，只能是关机接上一个光驱，虽然也有USB TO IDE的转换线可以把台式机的光驱变成USB接口的，但受限于主板的兼容性以及外置电源供电的稳定性。有时候会出这样那样的问题。那么，如何更快速的开始我们的工作呢，答案是将这些工具移植到网络上一台服务器上，客户机利用PXE BOOT功能来得到一个菜单，来使用这些功能。如下图：
service tftp
{
disable = no (默认是yes,这里改成no,启用它)
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/local/tftp/sbin/in.tftpd//改成源码编译安装生成的启动文件
server_args = -v -m /tftpboot/rules -s /tftpboot //-s 表示用/tftpboot作为tftp目录的根目录. -v打开日志在/var/log/messages便于调试， -m 指定重定向规则
per_source = 11
cps = 100 2
flags = IPv4
}
rg \\ / # Convert backslashes to slashes
rg \# @ # Convert hash marks to @ signs
rg /../ /..no../ # Convert /../ to /..no../
rg A a
rg B b
rg C c

tftp是由xinted来启动的,修改完后要记得service xinetd restart
