Juniper SSG5 Boot Loader升級詳細流程

在繼續閱讀前請先看過以下連結，非常重要!!

Juniper SSG5 關於imagekey的問題及移除與載入imagekey

Juniper SSG 5升級boot loader所需環境如下：

boot loader版本：Boot Loader Version 1.3.2
下載的新版本boot loader：Loadssg5ssg20v133.d
PC電腦：已啟動tftpd64 TFTP Server(CD中有免安裝版)，其預設根目錄預設為D:\TFTP，必須先將Loadssg5ssg20v133.d先放置到該目錄下。

PC電腦的ip地址是192.168.1.11(設定成固定IP，因為升級boot loader過程SSG5會重開機，而在boot loader模式下SSG5 沒有DHCP功能，不會自動分派ip位址。)。

然後使用超級終端機連接到SSG5 console port。

可參考連結 TFTPSERVER架設。

boot loader升級流程可分成兩個部分來討論：版本6.3.0r18(含)以前及版本6.3.0r19(含)以後。

一、版本6.3.0r19(含)以後

從6.3.0r19開始，升級防火牆OS要先載入image key，也導致無法直接將boot loader升級，必須先移除image key後，才能將boot loader升級成新版本，待升級完成之後再載入image key。

否則ssg系列升級BootLoader時會失敗,過程中則會出現以下錯誤訊息：

********Invalid DSA signature

********Bogus image - not authenticated

若要解決此問題有以下2個解決方法:

1.Update the New Image Authentication Key

2.using CLI delete crypto auth-key

我則是用第二種方法，連接登入CONSOLE後在CLI輸入下列命令來移除image key：

ssg5-serial-> delete crypto auth-key 刪除image key

之後重開SSG5：

然後參照Juniper SSG 5升級boot loader步驟即可

開機後再登入CONSOLE後在CLI輸入以下命令來載入image key

ssg5-serial-> save image-key tftp 192.168.1.11 imagekey.cer 載入image key

Load file from TFTP 192.168.1.11 (file: imagekey.cer).

!!!!!

tftp received octets = 863

tftp success!

Done

TFTP Succeeded

ssg5-serial->

PS:在執行delete crypto auth-key後會造成開機出現訊息

Loading default system image from on-board flash disk...

Done! (size = 13,402,112 bytes)

Ignore image authentication! (沒有image key無法認證)

所以必須執行save image-key tftp 192.168.1.11 imagekey.cer，開機出現訊息

Loading default system image from on-board flash disk...

Done! (size = 13,402,112 bytes)

Image authenticated! (認證成功)

大功告成!!

以下開始示範整個升級流程，乃超級終端機經由COM3接入CONSOLE埠後，超級終端機上顯示的畫面

System change state to Active(1)

password:

ssg5-serial-> delete crypto auth-key　　　　刪除 image key

ssg5-serial-> reset 重開機

System reset, are you sure? y/[n] y 按y

In reset ...

中間的部分省略，請自行參考”一、版本6.3.0r18(含)以前”的內容。

password:

ssg5-serial-> save image-key tftp 192.168.1.11 imagekey.cer 載入image key

Load file from TFTP 192.168.1.11 (file: imagekey.cer).

!!!!!

tftp received octets = 863

tftp success!

Done

TFTP Succeeded

ssg5-serial->

大功告成!!

執行過save image-key tftp 192.168.1.11 imagekey.cer後，重開機會出現訊息

Loading default system image from on-board flash disk...

Done! (size = 13,402,112 bytes)

Image authenticated!　　　　認證成功

上述做法乃是標準做法，若您運行中的ScreenOS版本的範圍是在新的Image Key適用版本之內(適用於6.3.0r19以後之版本)，您就必須採用此辦法。

二、版本6.3.0r18(含)以前

而若您運行中的ScreenOS版本的範圍是在舊的Image Key適用版本之內(適用於6.3.0r18以前之版本)，則您的升、降bootloader版本的程序就可以省略移除與載入Image Key的步驟。

以下開始示範整個升級流程，乃超級終端機登入CONSOLE埠後，超級終端機上顯示的內容：

System change state to Active(1)

password:

ssg5-serial-> reset 重開機

System reset, are you sure? y/[n] y

In reset ...
