批量生成SecureCRT的Session文件

因爲在工作中，批量的上架服務器，一次幾十上百臺，如果手動一臺一臺的在SecureCRT中添加過於麻煩，於是自己編寫了一個Perl腳本批量創建，好 用又快速：
1、編輯一個列表文件，包括IP和主機名的，但是IP要以lan:開頭，主機名要以hostname:開頭，這個絕對不會難倒你吧。
[test@mantis create_session]$ vim list
lan:192.168.21.30       hostname:test1

2、運行腳本生指定ssh端口爲22
ssh用戶爲nagios
ssh的password爲6個0，(這裏輸入的是SecureCRT自己加密後的字符)
指定列表文件名爲list

[test@mantis create_session]$ perl cre_sess.pl --port 22 --user nagios --password 8d860cf50f78af1a2833433076d288f3 --list list
運行該腳本需要先確認當前目錄下有session_dir這個目錄
已經修正，如果不存在session_dir目錄，腳本將會自行創建。

3、運行後可以看到已經有Session文件了
[test@mantis create_session]$ ls session_dir/
(test0001) 192.168.21.30.ini

這裏列表裏只有一個主機，所以只生成一臺，如果有多臺，就會都生成在這個目錄裏的。接下來可以把這些文件拷到SecureCRT的Session目錄裏使用了。
