遇到一件有趣的事，我們公司買來的source code - AMI MegaRAC要求ping得到zone(domain-name)，才能nsupdate更新/註冊DNS...
在任何一個Linux不需要這個條件，都能順利註冊DNS

How to Install or upgrade to "archived-Kernel 6.y" on CentOS Stream 9
6.y = the version of file that who's location is in "archive" folder

前陣子看到的資料: AMI USB0 under Windows
Windows:
1. Get-NetAdapter -InterfaceDescription "*NDIS*"
2. pnputil -i -a .\rndis.inf
3. Get-NetAdapter -InterfaceDescription "*NDIS*" | Select-Object -Property Name | findstr "Ethernet" | New-Variable -Name "host_intf_dev"
4. netsh interface ip set address name=$host_intf_dev static 169.254.0.18 255.255.0.0
還沒有環境確認

#環境確認:
#確認已安裝的群組套件
yum grouplist
#確認已安裝 RPM Development Tools；若沒有安裝，yum groupinstall 'RPM Development Tools'
yum -y install autoconf automake libtool ncurses ncurses-devel ncurses-term readline readline-devel openssl-devel

剛好工作上需要使用EOL的CentOS，紀錄一下怎麼用
跟設定內網URL資源一樣

遇到鎖HTTP，只能HTTPS連線的BMC WebUI，但功能複驗流程把HTTPS關掉了，只能用inband ipmi command把BMC還原成default狀態...
-----------------------------------------------------------------------------------------------------
How to restore BMC to factory default by command(AMI code)
# ipmitool raw 0x32 0x66
印象中以前的AMI BMC (BMC WebUI還沒使用HTML5的FW)只需要用上面的command

從Systemd(Systemctl)設置：
$ cp /usr/lib/systemd/system/serial-getty@.service /etc/systemd/system/serial-getty@ttyS0.service
$ vi /etc/systemd/system/serial-getty@ttyS0.service
//# Modify "ExecStart" line as below.
//# E.g.: Rate=57600, 
>> ExecStart=-/sbin/agetty 57600 %I $TERM
//# E.g.: Rate=115200, 
>> ExecStart=-/sbin/agetty 115200 %I $TERM 
//# E.g.: Rate=115200, 
>> ExecStart=-/sbin/agetty 115200 %I $TERM 
//# E.g.: Rate=115200, 
>> ExecStart=-/sbin/agetty -o '-p -- \\u' 115200 %I $TERM
//# Recommend remove "--keep-baud" that if you expect it take effect immediately.(Mean without reboot or others operation.)
$ systemctl daemon-reload
//# For a built in serial port /dev/ttyS0
$ systemctl enable --now serial-getty@ttyS0.service
$ systemctl status serial-getty@ttyS0.service
