批量生成SecureCRT的Session文件

因为在工作中，批量的上架服务器，一次几十上百台，如果手动一台一台的在SecureCRT中添加过于麻烦，于是自己编写了一个Perl脚本批量创建，好 用又快速：
1、编辑一个列表文件，包括IP和主机名的，但是IP要以lan:开头，主机名要以hostname:开头，这个绝对不会难倒你吧。
[test@mantis create_session]$ vim list
lan:192.168.21.30       hostname:test1

2、运行脚本生指定ssh端口为22
ssh用户为nagios
ssh的password为6个0，(这里输入的是SecureCRT自己加密后的字符)
指定列表文件名为list

[test@mantis create_session]$ perl cre_sess.pl --port 22 --user nagios --password 8d860cf50f78af1a2833433076d288f3 --list list
运行该脚本需要先确认当前目录下有session_dir这个目录
已经修正，如果不存在session_dir目录，脚本将会自行创建。

3、运行后可以看到已经有Session文件了
[test@mantis create_session]$ ls session_dir/
(test0001) 192.168.21.30.ini

这里列表里只有一个主机，所以只生成一台，如果有多台，就会都生成在这个目录里的。接下来可以把这些文件拷到SecureCRT的Session目录里使用了。
