I'm alive, I'm here！ 人生的两大悲剧：想要的没得到和想要的得到了。
Linux或者Mac OS生成一个key
ssh-keygen -t rsa
用scp上传到Mikrotik
scp -P端口 ~/.ssh/id_rsa.pub [email protected]:id_rsa.pub
在Mikrotik内导入key
[admin@MikroTik] > /user ssh-keys import public-key-file=id_rsa.pub user=admin
打印查看
[admin@MikroTik] > /user ssh-keys print
Flags: R - RSA, D - DSA
# USER BITS KEY-OWNER
0 R admin 2048 XXXXXXX

原文标题：How To Connect To Cisco Devices Via Serial Port Using GNU/Linux
Filed under: Linux, SysAdmin — acidborg @ 10:17
Description: to connect your computer to a Cisco device via its console port, you usually need a RJ45 rolled cable. You can use a RJ-45 to DB-9 Female if your computer has a serial port.
RJ-45 to DB-9 Female
To communicate through the serial port with the Cisco device, you need Minicom, a terminal emulator software.

修改用户密码

在当前用户下修改密码
[admin@MikroTik]>password #修改本目录用户密码备份命令

修改/etc/default/grub
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto vconsole.keymap=us rhgb quiet"
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto enforcing=0 vconsole.keymap=us rhgb quiet"
添加 enforcing=0 或者net.ifnames=0 biosdevname=0
GRUB_DISABLE_LINUX_UUID=true
存盘退出
echo "GRUB_DISABLE_LINUX_UUID=true" >> /etc/default/grub
sed -i 's#GRUB_CMDLINE_LINUX="#GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0 #g' /etc/default/grub
grub2-mkconfig --output /boot/grub2/grub.cfg
背景
Mac系统语言设置的是英文，安装的Office语言默认也是英文。由于习惯了中文Office的使用，想把Office的语言设置成中文，
方法之一就是直接修改系统的默认语言设置，但并不希望直接修改系统语言，仅想修改Office软件的默认语言
实现
1获取App的Bundle Identifier
Bundle Identifier是应用软件的标识，以Microsoft Word为例，Terminal中输入命令：
mdls -name kMDItemCFBundleIdentifier /Applications/Microsoft\ Word.app
2得到结果：
kMDItemCFBundleIdentifier = "com.microsoft.Word"
3修改应用程序默认语言
该操作需要用到第一步查到的应用程序Bundle Identifier，本例中是com.microsoft.Word，Terminal中输入命令：
defaults write com.microsoft.Word AppleLanguages '("zh_CN")'
