环境：【wind2003[open Tftp server] + virtualbox:ubuntn10 server】
tftp ： Open TFTP Server
ubuntn
python + pyexpect
采用虚拟机原因： pyexpect 不支持windows
注：原打算采用secrueCrt 脚本编写，因实践中发现没有使用linux下pexpect易用，灵活 ，之前习惯使用expect,因tcl【语法】没有python易用、易维护
编写些程序原因：
最近出了比较严重故障：因netscreen设备bug,一个节点主备设备同时出故障，更换设备后，发现备份配置文件出现乱码【中文】，不能直接使用。
考虑设备在内网，目前有近300台数通设备，因此采用原始tftp备份方式
因备份设备不多：暂只考虑功能，程序效率放在次要
发布：
基本实现netscreen,cisco ios, hw vrp，h3c f1000设备 备份程序
分离出设备信息配置 2.增加备份是否成功检测
问题：
1 未解决ping 不可达主要，反馈慢问题 解决办法：ip 一项，不支持主机名，在 ipCheck函数中添加检查地址进行解决
2.登录设备部署expect代码，没有处理认证失败情况，或者超时等基本检查问题
