由于專案需要，需要在kali上添加一條路由，并且保證重啟后仍然生效，
經查找發現有兩種可行的方法：
1、修改/etc/network/interfaces組態檔，添加一行，如：
up route add -net 10.105.10.0 netmask 255.255.255.255 gw 192.168.1.1 eth0
-net指這是一條網路路由（ip地址主機位為0）
gw指下一跳
2、修改rc.local，添加：
route add -net 192.168.114.0/24 dev eth0
或
route add -net 192.168.114.0/24 gw 192.168.3.254
那么，為了保證重啟仍然生效需要將它寫入rc.local組態檔，
--------------------------------------------分割線--------------------------------------------------------
第一個方法添加路由后，使用route命令查看路由表；的確是添加了，但實際測驗中發現沒有起作用，目標仍然不可訪問，（玄學問題）
第二個方法遇到一個問題，kali把rc.local“ 服務化”了，并沒有rc.local組態檔怎么辦呢？
解決方法：
vim /etc/systemd/system/rc-local.service
將內容替換為
[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local
[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99
[Install]
WantedBy=multi-user.target
然后
touch /etc/rc.local（正常情況下/etc/rc.local并不是組態檔本身，而是/etc/rc.d/rc.local的軟連接；但徒增麻煩不建議那么做）
記得賦予執行權限
chmod +x /etc/rc.local
vim /etc/rc.local
添加
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
exit 0
插入腳本就在exit 0之前即可
重啟rc-local服務
systemctl restart rc-local.service
設定開機自啟動
systemctl enable rc-local
---------------------------------------你以為這樣就結束了？-------------------------------------------
我將添加路由的shell命令添加到rc.local之后重啟發現，并沒有成功添加路由；
執行systemctl status rc-local.service發現報錯顯示“網路未啟動”，，，，
在檢查了各種錯誤之后我斷定，是啟動優先級沒有起作用
無奈曲線解決，在啟動腳本里添加sleep命令延遲執行腳本
詳見我的shell腳本：
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
/usr/local/bin/route-eth0
exit 0
/usr/local/bin/route-eth0:
#!/bin/bash
sleep 15s
route add -net 192.168.114.0/24 dev eth0
exit0
最終問題解決，目的是給更多人帶來方便，
