Juniper防火墙丢失ScreenOS
Juniper的防火墙是一台硬件防火墙,有硬件系统也有软件系统也就是ScreenOS,硬件会出故障软件自然也会出故障,在实际使用中我就碰到过多次Juniper防火墙ScreenOS丢失的情况,大多数情况是因为突然断电造成的。
下面就介绍一下如何在丢失ScreenOS的情况下重新安装ScreenOS。
将PC机与防火墙用console线和网线相连接。
断电重启防火墙,在命令行提示有Hit any key to run loader时,按任意键进入Loader。
根据提示,输入Boot File Name、Self IP Address和TFTP IP Address。同时打开TFTP软件,设置好下载目录。
重启后在超级终端会出现如下提示:

安装好ScreenOS之后重启防火墙,这样就完成了ScreenOS的回复,一般来说原有的配置应该还会在,如果配置也丢失了,可以讲以前保存过的配置文件导入。
