KaLi添加路由问题,设置开机自启动脚本rc.local文件不存在问题

由于项目需要,需要在kali上添加一条路由,并且保证重启后仍然生效。

经查找发现有两种可行的方法:

1、修改/etc/network/interfaces配置文件,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指这是一条网络路由(ip地址主机位为0)

gw指下一跳

2、修改rc.local,添加:

route add -net 192.168.114.0/24 dev eth0

route add -net 192.168.114.0/24 gw 192.168.3.254

那么,为了保证重启仍然生效需要将它写入rc.local配置文件。

--------------------------------------------分割线--------------------------------------------------------

第一个方法添加路由后,使用route命令查看路由表;的确是添加了,但实际测试中发现没有起作用,目标仍然不可访问。(玄学问题)

第二个方法遇到一个问题,kali把rc.local“ 服务化”了,并没有rc.local配置文件怎么办呢?

解决方法:

vim /etc/systemd/system/rc-local.service

将内容替换为

[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(正常情况下/etc/rc.local并不是配置文件本身,而是/etc/rc.d/rc.local的软连接;但徒增麻烦不建议那么做)

记得赋予执行权限

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 

插入脚本就在exit 0之前即可

重启rc-local服务

systemctl restart rc-local.service

设置开机自启动

systemctl enable rc-local

---------------------------------------你以为这样就结束了?-------------------------------------------

我将添加路由的shell命令添加到rc.local之后重启发现,并没有成功添加路由;

执行systemctl status rc-local.service发现报错显示“网络未启动”。。。。

在检查了各种错误之后我断定,是启动优先级没有起作用

无奈曲线解决,在启动脚本里添加sleep命令延迟执行脚本

详见我的shell脚本:

#!/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

最终问题解决,目的是给更多人带来方便。
