花了几天时间写了个小工具用于自动登录所有用telnet及SSH方式管理的设备，可以支持自定义登录过程文件，可选获得shell或者完成特定任务后退出。
欢迎大家下载测试，提出宝贵意见和需要的其它实用功能。

[root@localhost:/root/]#auto_cmd_tool –help
Usage: auto_cmd_tool [OPTION] –l <login type> -t <target-device type> <target host> [port]
-c　[配置文件名] 指定全手工配置文件，程序完全按照该配置文件执行。指定该参数将完全忽略-t,-p,-u等参数。
-t  [设备类型名] 目标设备类型。目标设备类型列表见/etc/act/dcfg目录中的文件名列表。如cisco.cfg,quidway.cfg,linux.cfg等，可以支持自定义cfg文件到该目录之下。设备类型名应与该类文件名的主文件名相同，如指定了一个不存在该类配置文件的设备名则将退出。
-1 [第一层密码] 该参数必须与-t参数共用，指定配置文件内$PASSWORD_0变量的内容。
-2 [第二层密码]　　　该参数必须与-t参数共用，指定配置文件内$PASSWORD_1变量的内容。
- 3/4[第三、四层密码]  同-1/-2。
-u  [用户名] 该参数必须与-t参数共用，指定配置文件内$USERNAME变量的内容。
-s 表示在执行完脚本之后，不要退出进程，直接获取一个用户的shell。
工具用途：
   自动化的可配置的自动执行工具，可支持telnet及ssh登录。可自定义配置文件以描述任意设备的登录过程，加-s参数可直接获得自动登录后的一个shell，不加-s参数也可以调用它完成一些自动更新设备信息功能。
自动登录CISCO路由器举例：
cisco.cfg文件：
["Username:",$USERNAME,"Password:",5,normal]
[NULL,$PASSWORD_1,">",5,normal]
[NULL,"enable","Password:",5,normal]
[NULL,$PASSWORD_2,"#",5,normal]
[NULL,"config terminal","CNTL/Z.",5,normal]
["(config)#","do show ver",NULL,5,normal]
使用auto_cmd_tool自动登录路由器：
[root@linux-develop debug]# ./auto_cmd_tool -l telnet -t cisco -u cisco -1 cisco -2 123456 192.168.1.250 -s
