1.BMC虚拟多网口：macvlan是kernel提供的一种网卡虚拟化技术，可将网卡（不一定是真实的物理网卡）虚拟出多个接口，这网卡称为master或父接口，这些虚拟接口和外面环境通信都是通过父接口

1.1 bridge：ip netns add ns001 / ns002

macvlan模拟的mac不同，如下第一行和第二行创建两个以ens32为父接口的macvlan1和macvlan2虚拟网口。

如下将ns001/2绑定网卡macvlan1/2，进入ns001虚拟环境，将网卡up起来。

如下添加ip，不通原因是bridge模式和父接口（.138）是不通的。

如下在ns002虚拟环境，宿主机（76.1）指的windows这台机器，如下两个都是往外ping。

1.2 private：FB Openbmc（AST2520实物芯片）和OcpOpenBMC（qemu ast2500-evb）以及X86 Ubuntu上验证过， Kernel版本均5.0+

编译Kernel：BMC/CPU OS的Linux Kernel Config里面加CONFIG_MACVLAN=m/y

如下在编译的服务器上编译完后，如果找不到就删除build目录重新编译。

如下在烧录的机器上烧录镜像后，vi第一行.dep文件。

如下不用insmod kernel/drivers/net/maclan.ko。

创建/启动网卡/获取DHCP地址：创建网卡以eth0为目标物理网口，虚拟网口的MAC地址自定义，mode可以选择private不能互通，bridge内部互通等

假设生成5个虚拟网口eth0.1-eth0.5命令如下，ifconfig检查5个虚拟网口的IP地址和MAC地址（都不一样）：

ip link add link eth0 dev eth0.1 address D6:D2:52:A8:28:28   type macvlan  mode private   
ip link add link eth0 dev eth0.2 address D6:D2:52:A8:28:29   type macvlan  mode private   
ip link add link eth0 dev eth0.3 address D6:D2:52:A8:28:2a   type macvlan  mode private   
ip link add link eth0 dev eth0.4 address D6:D2:52:A8:28:2b   type macvlan  mode private   
ip link add link eth0 dev eth0.5 address D6:D2:52:A8:28:2c   type macvlan  mode private   
ifconfig eth0.1 up
ifconfig eth0.2 up
ifconfig eth0.3 up
ifconfig eth0.4 up
ifconfig eth0.5 up
dhclient eth0.1
dhclient eth0.2
dhclient eth0.3
dhclient eth0.4
dhclient eth0.5

配置路由表：由于5个网口都被分配在一个网段如10.75.159.0/24（掩码一样），导致Linux内部路由会以高优先级的网口如eth0来响应外部的arp/icmp/tcp等各种网络请求。为了达到5个虚拟网口能在同网段以5个独立网口的形式工作，呈现5个独立网口MAC地址，需要配置路由表

获取Gateway网关地址：用route -n 命令获取路由表和Gateway（10.75.159.1）地址。

配置路由表：数量以实际虚拟网卡数量为准，需要替换网关IP和每个网口的IP。下面命令中10.75.159.1为网关地址，10.75.159.117等为虚拟网口的IP地址，10.75.159.0/24为网段和NETMASK。

echo "210 eth0table" >> /etc/iproute2/rt_tables    # 210越大优先级越低
echo "220 eth1table" >> /etc/iproute2/rt_tables
echo "230 eth2table" >> /etc/iproute2/rt_tables
echo "240 eth3table" >> /etc/iproute2/rt_tables
echo "250 eth4table" >> /etc/iproute2/rt_tables

ip route add 10.75.159.0/24 dev eth0.1 src 10.75.159.117 table eth0table
ip route add 10.75.159.0/24 dev eth0.2 src 10.75.159.120  table eth1table
ip route add 10.75.159.0/24 dev eth0.3 src 10.75.159.121 table eth2table
ip route add 10.75.159.0/24 dev eth0.4 src 10.75.159.125  table eth3table
ip route add 10.75.159.0/24 dev eth0.5 src 10.75.159.132 table eth4table

ip route add default dev eth0.1 via 10.75.159.1 table eth0table
ip route add default dev eth0.2 via 10.75.159.1 table eth1table
ip route add default dev eth0.3 via 10.75.159.1 table eth2table
ip route add default dev eth0.4 via 10.75.159.1 table eth3table
ip route add default dev eth0.5 via 10.75.159.1 table eth4table

ip rule add from 10.75.159.117 table eth0table
ip rule add from 10.75.159.120 table eth1table
ip rule add from 10.75.159.121 table eth2table
ip rule add from 10.75.159.125 table eth3table
ip rule add from 10.75.159.132 table eth4table

远端服务器检查：ping 10.75.159.117/120/121/125/132

如下只有发起ping 117才能看到117这个ip，BMC侧IP的MAC地址与远端服务器获取的一致，符合预期。使用tcp方式测试：BMC端（服务端）iperf -s -p port，远端（客户端）iperf -c BMCIP -t 1000 -i 3 -p port。

案例：iproute2，设置路由重启后不丢失/etc/network/interfaces：up route add -host 10.1.1.2 dev eth1

如下default via可省略。

注意如下是规则rule，不是route。

如下没指定路由表就会到main表中。



hping3 -I eth0 -a 10.75.159.37 -S 10.75.159.138 -p 8080 -i u100 发起攻击，iptables限制端口，限制连接数防止攻击。

3.rsyslog：rsyslogd一个进程 ，管理每个进程发来的log并往/var/log里写，syslog函数将log写给rsyslogd进程。

ident将是一个标记，省略的话即打印出进程的名字如下。

facility默认是user。


如下排除文件中以#开头的和去除空行。

左面是对应的LC CPLD寄存器的名字 中间是 切换后器件在的通道号 右面是器件位号

测完了要把这个节点值再 写回0




这个硬件给错了 这个是ch1
