安装ubuntu18.04，可以使用虚拟机安装
点击安装VMware Tool
桌面会出现如下图标
双击打开VMware Tools，复制如下图所示的文件到Home目录
打开终端，切换到管理员权限（如果忘记管理员密码可以使用sudo passwd root修改密码）
解压vmwaretools
tar -xvf VMwareTools-10.3.22-15902021.tar.gz
切换到vmware-tools-distrib目录下
cd vmware-tools-distrib

备份系统原始源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
更改源
sudo gedit /etc/apt/sources.list
将原始内容删除，替换ubuntu18.04源.txt里面的内容
更新源
sudo apt-get update
安装ifconfig指令工具包
sudo apt install net-tools
安装vim工具包
sudo apt install vim
安装支持mptcp内版本的内核
软件包下载地址
Releases · multipath-tcp/mptcp (github.com)
https://github.com/multipath-tcp/mptcp/releases
将软件包
linux-headers-5.4.230.mptcp_20230203134326-1_amd64.deb
linux-libc-dev_20230203134326-1_amd64.deb

linux-mptcp_v0.96_20230203134326-1_all.deb
拷贝到ubuntu系统里面，然后执行安装
安装指令
解压软件包
sudo dpkg -i linux*.deb
安装软件包
sudo apt-get install –f
开启开机选择内核版本选项
打开/etc/default/grub文件
注释掉#GRUB_HIDDEN_TIMEOUT=0
更新grub

重启设备，选择支持mptcp版本内核
重启之后会自动进入内核选择界面，按键盘的上下键选择Ubuntu高级选项（Advanced options for Ubuntu）,然后回车进入内核选择界面，选择带mptcp的内核版本，然后回车启动
关闭mptcp_checksum选择
echo 0 > /proc/sys/net/mptcp/mptcp_checksum
开启debug
echo 1 > /proc/sys/net/mptcp/mptcp_debug
查看mptcp是否默认开启，为1表示开启
root@w0425-virtual-machine:/home/w0425# cat /proc/sys/net/mptcp/mptcp_enabled
1
开启和关闭mptcp方法
开启
echo 1 > /proc/sys/net/mptcp/mptcp_enabled
关闭
echo 0 > /proc/sys/net/mptcp/mptcp_enabled
安装测试工具
Iperf & tcpdump
sudo apt-get install iperf iperf3 tcpdump
git
sudo apt-get install git
curl
sudo apt-get install curl
mptcpd
电脑浏览器手动下载
https://github.com/multipath-tcp/mptcpd/archive/refs/tags/v0.12.tar.gz
mptcpd-0.12.tar.gz
编译安装mptcpd
安装软件包依赖工具
sudo apt-get -y install autoconf automake libtool autoconf-archive pkg-config
安装ell工具
git clone git://git.kernel.org/pub/scm/libs/ell/ell.git
git checkout 0.56
cd ell
./bootstrap
./configure
make install
安装mptcpd
拷贝mptcpd-0.12.tar.gz到ubuntu
解压
tar –xvf mptcpd-0.12.tar.gz
编译安装
cd mptcpd-0.12
./bootstrap
./configure
mke install
检查是否安装成功
root@w0425-virtual-machine:/home/w0425/mptcp/mptcpd-0.12# mptcpize
root@w0425-virtual-machine:/home/w0425/mptcp/mptcpd-0.12# mptcpize
Usage: mptcpize CMD
mptcpize - a tool to enable MPTCP usage on unmodified legacy services
Available CMDs:
run [-d] prog [<args>] Run target program with specified
arguments, forcing MPTCP socket usage
instead of TCP. If the '-d' argument
is provided, dump messages on stderr
when a TCP socket is forced to MPTCP.
enable <unit> Update the systemd <unit>, forcing
the given service to run under the
above launcher.
disable <unit> Update the systemd <unit>, removing
the above launcher.
Report bugs to <mptcp@lists.linux.dev>.
Ubuntu配置
网卡设置
需要实体网卡，不能使用nat模式，nat模式会出现mptcp异常
查看内核是否启动mptcp
关闭checksum
默认mptcp配置如下，需要手动关闭checksum
需要确认net.mptcp.mptcp_enabled=1
指令如下：
sysctl –w net.mptcp.mptcp_checksum=0
启动tcpdump
tcpdump –ni any port 8888 –vvvv &
启动iperf
mptcpize run iperf –c 192.168.1.1 –p 8888 –P 2 –t 30 –i 1
抓包结果分析
192.168.1.20 to 192.168.1.1 带有mptcp capable表示客户端请求是支持mptcp的
192.168.1.1 to 192.168.1.20 带有mptcp capable字段表示服务器回复支持mptcp
