Unlock root account in HP-UX
From
How to unlock locked root account in HP-UX
How to unlock locked root account in HP-UX
By default HP-UX disables the root account if there is repeated number of failed (bad password) attempts. If you root account has been disabled because of bad password there are two options you two ways you can unlock the account without rebooting the server.
1.If you have sudo installed and your account is setup with root privileges then you can login as sudo su and then you can unlock the account using modprpw
$/usr/local/bin/sudo su –
##/usr/lbin/modprpw –l –k root
2.If you don't have sudo setup then other way out is to check on GSP console if you already have root logged in then you can re-enable root account from GSP console

Solaris Explorer
當你Solaris OS發生問題要怎麼辦
首先，你必須將系統的狀況回報給維護廠商
1. 執行 Explorer 程式:
# cd /opt/SUNWexplo/bin
# ./explorer
如果要針對Storage問題，執行指令如下
# ./explorer -w default,storage,fru
當程式執行完畢你會看到
explorer: Explorer finished 的訊息
2. 當程式執行完後,
# cd /opt/SUNWexplo/output
# ls
explorer.XX-2007.12.16.07.43.XXXX
explorer.XXXXXXXXX-2007.12.16.07.43.tar.gz
把 explorer*.tar.gz 寄出給維護廠商

Sybase's Login
Sometimes, we would like to know where a sybase's user come from? (e.g. IP)
1.) Find out the login's suid by using sp_displaylogin
1> sp_displaylogin person1
2> go
Suid: 2608
Loginame: person1
Fullname:
Default Database: mydb
Default Language:
Auto Login Script:
Configured Authorization:
Locked: NO
Date of Last Password Change: Nov 27 2007 11:03AM
Password expiration interval: 0
Password expired: NO
Minimum password length: 6
Maximum failed logins: 0
Current failed login attempts:
(return status = 0)
2.)Then select from sysprocesses by using the "suid"
1> select * from sysprocesses where suid=2608
2> go
spid kpid enginenum status suid hostname
program_name hostprocess cmd cpu physical_io
memusage blocked dbid uid gid
tran_name
time_blocked network_pktsz fid execlass

Logging for executed commands
Solaris作業系統可以通過設置日 誌檔可以對每個用戶的每一條命令進行紀錄，這一功能默認是不開放的，為了打開它，需要執行/usr/lib/acct目錄下的accton檔，格式如下 /usr/lib/acct/accton /var/adm/pacct，在sun的手冊上，只有這一種用法，但這樣做的缺點是明顯的，大多數有經驗的入侵者一定不會放過/var/adm和 /var/log這兩個目錄的，如果它們看到有pacct這個東西，不刪才怪。針對這種情況其實有個很好的解決辦法，執行 /usr/lib/acct/accton 後面跟一個別的目錄和檔即可，如/usr/lib/acct/accton /yiming/log/commandlog，這樣入侵者不會在/var/adm/下看到pacct，入侵者也許會刪掉message，syslog等 日誌，但他並不知道實際上他所有的操作都被記錄在案，管理員事後只要把commandlog這個檔拷貝到/var/adm下，改為pacct ，同時執行讀取命令lastcomm，就一切盡在掌握啦。如lastcomm hack，可得到下面的輸出結果：

Solaris "root password" Recovery
今天從 http://solaris.tophk.net/forum/viewtopic.php?t=117 & http://wiki.gceclub.sun.com.cn/index.php/Opensolaris_chinese_faq 看到的 =)
較近的 solaris 10u1 & 11 (是用 grub 開機的):
1. start from "fail safe" mode
2. 系统會問你是否 mount "/" 分區到 /a 上，選 yes
3. 编辑 "/a/etc/shadow"，delete "root" 的passwords，save & reboot
1.將安裝Solaris 10光碟片第一片放進來，並開機
2.選擇安裝方式，直接按【Enter】繼續
3.會開始拷貝系統安裝所需要的資料，大約等了5分鐘，會進入選擇語言畫面
4.利用滑鼠按下右鍵，選擇【Windows\New】，會出現一個新的視窗
5.輸入 mount /dev/dsk/c0d0s0 /mnt指令，會將根目錄Mount在mnt目錄下
6.輸入chmod 600 /mnt/etc/shadow
7.編輯/mnt/etc/shadow檔案，將root這一行的第二個密碼欄位Del掉，使其 保留空白
8.儲存結束，並重新開機，記得光碟片要拿起來，就不用輸入密碼，可以直接 登入
較近的 solaris 10u1 & 11 (是用 grub 開機的):
1. start from "fail safe" mode
2. 系统會問你是否 mount "/" 分區到 /a 上，選 yes
3. 编辑 "/a/etc/shadow"，delete "root" 的passwords，save & reboot
Solaris 9 & 10 (不是用 grub 開機的):
1. 用 disk 1 boot 機
[X86]： BIOS set cdrom boot 機
[Sparc]：press "Stop+a" (SUN keyboard) or "ctrl+break" (PC keyboard) 進入到OBP & enter：
ok boot cdrom -s
2. 然后，mount "/" 分區，edit "shadow"：
