+``` +~ ___宿主机___ 即当前运行Linux的机器, 蓝图中用`root`表示; + +~ ___路由器___ 并非现代意义上的路由器, 而是一台普通的主机, 跟 ___交换机1___ 和 ___交换机2___ 合在一起更像是现代的路由器; + +此网络拓扑对应的蓝图文件是 [docs/example.json](docs/example.json). + +最终要实现的是pc之间互通, pc可以连接外网. + +编译蓝图: +```shell script +java -jar vnet-lab.jar docs/example.json > example.sh && chmod 755 example.sh +``` +之后的命令都在Linux上执行; + +创建虚拟网络: +```shell script +sudo ./example.sh create +``` +创建完之后可以执行`ip netns`查看有哪些主机, 这个案例中会输出: +```text +pc4 (id: 3) +pc3 (id: 2) +pc2 (id: 1) +pc1 (id: 0) +router1 (id: 4) +``` + +#### pc之间的连通 +在`pc1`中ping `pc2`: +```shell script +./scripts/netenter pc1 ping 192.168.65.2 +``` +`pc1`和`pc2`在同一个交换机下, 可以ping通; + +再试试ping `pc3`: +```shell script +./scripts/netenter pc1 ping 192.168.66.1 +``` +这个时候能不能ping通取决于router1上的路由转发有没有打开: +```shell script +./scripts/netenter router1 cat /proc/sys/net/ipv4/ip_forward +``` +如果输出1, 说明路由转发已经打开, 那前面的ping应该也是成功的; +如果输出0, 说明路由转发没打开, 可以通过这个命令打开: +```shell script +echo 'echo "1">/proc/sys/net/ipv4/ip_forward' | ./scripts/netenter router1 +``` +现在`pc1`到`pc4`的网络可以互通了; + +#### pc到路由器的连通 +现在试试ping路由器`router1`的外网端口`eth0`: +```shell script +./scripts/netenter pc1 ping 192.168.64.1 +``` +可以ping通; + +#### pc到宿主机的连通 +试试ping宿主机的端口`vroute1`: +```shell script +./scripts/netenter pc1 ping 192.168.64.254 +``` +发现ping不通; +同样宿主机也无法ping通`pc1` +(如果ping通了, 也许是因为宿主机的网关那边有相同的ip, 或者因为宿主机能自己学习路由表, 例如安装了OSPF相关软件): +```shell script +ping 192.168.65.1 +``` +ping不通的原因是宿主机不知道192.168.65.1在哪, +要让pc到宿主机连通有两个方案, 分别是NAT和路由表: +- NAT方案是在router1上开启NAT, 将pc的地址伪装成192.168.64.1, 再跟宿主机通信, +这个方案下, 宿主机不知道pc的存在, router1上还能配置防火墙规则禁止宿主机主动连接pc, +就跟我们平时用的路由器那样; +- 路由表方案是在宿主机上增加路由规则, 让宿主机知道pc在vroute1端口下, +这个方案下宿主机和pc可以直接互联, 如果我们把宿主机当成ISP, 那pc就相当于有了公网IP. + +为了简单, 选择路由表方案, 直接在宿主机增加一条路由规则: +```shell script +sudo ip route add 192.168.64.0/18 via 192.168.64.1 +``` +(`192.168.64.0/18`这个网段包含了`192.168.65.1`) + +现在`ping 192.168.65.1`, `./scripts/netenter pc1 ping 192.168.64.254`都能通了. + +#### pc到外网 +首先打开宿主机的路由转发: +```shell script +sudo sh -c 'echo "1">/proc/sys/net/ipv4/ip_forward' +``` +这个时候尝试ping外网地址`./scripts/netenter pc1 ping 114.114.114.114`, 还是ping不通, +原因跟上一节一样, 解决方案也是一样, 但是我们不应该改宿主机上级路由的路由表, 所以只能用NAT方案. +假设宿主机的外网端口是`eth0`, 那么执行这条命令增加NAT: +```shell script +sudo iptables -t nat -A POSTROUTING -s 192.168.64.0/18 -o eth0 -j MASQUERADE +``` +再来一次`./scripts/netenter pc1 ping 114.114.114.114`, +好耶, pc可以访问外网了! (如果pc还是上不了网, 是不是因为宿主机本来就不能上网??) + +本例完结, 其实宿主机也被当成路由器了. \ No newline at end of file diff --git a/docs/example.json b/docs/example.json new file mode 100644 index 0000000..9d25207 --- /dev/null +++ b/docs/example.json @@ -0,0 +1,106 @@ +{ + "hosts": [ + { + "name": "router1", + "gateway": "192.168.64.254" + }, + { + "name": "pc1", + "gateway": "192.168.65.254" + }, + { + "name": "pc2", + "gateway": "192.168.65.254" + }, + { + "name": "pc3", + "gateway": "192.168.66.254" + }, + { + "name": "pc4", + "gateway": "192.168.66.254" + } + ], + "switches": [ + { + "name": "vsw1" + }, + { + "name": "vsw2" + } + ], + "links": [ + { + "from": { + "peer": "pc1", + "if": "eth0", + "ipv4": "192.168.65.1/24" + }, + "to": { + "peer": "vsw1" + } + }, + { + "from": { + "peer": "pc2", + "if": "eth0", + "ipv4": "192.168.65.2/24" + }, + "to": { + "peer": "vsw1" + } + }, + { + "from": { + "peer": "pc3", + "if": "eth0", + "ipv4": "192.168.66.1/24" + }, + "to": { + "peer": "vsw2" + } + }, + { + "from": { + "peer": "pc4", + "if": "eth0", + "ipv4": "192.168.66.2/24" + }, + "to": { + "peer": "vsw2" + } + }, + { + "from": { + "peer": "router1", + "if": "br-lan0", + "ipv4": "192.168.65.254/24" + }, + "to": { + "peer": "vsw1" + } + }, + { + "from": { + "peer": "router1", + "if": "br-lan1", + "ipv4": "192.168.66.254/24" + }, + "to": { + "peer": "vsw2" + } + }, + { + "from": { + "peer": "router1", + "if": "eth0", + "ipv4": "192.168.64.1/24" + }, + "to": { + "peer": "root", + "if": "vroute1", + "ipv4": "192.168.64.254/24" + } + } + ] +} \ No newline at end of file diff --git a/pom.xml b/pom.xml new file mode 100644 index 0000000..9cb4ddc --- /dev/null +++ b/pom.xml @@ -0,0 +1,42 @@ + + + 4.0.0 + + github.jjm2473 + vnet-lab + 1.0-SNAPSHOT + + + + com.alibaba + fastjson + 1.2.50 + + + commons-io + commons-io + 2.6 + + + org.testng + testng + 6.14.3 + test + + + + + + + org.apache.maven.plugins + maven-compiler-plugin + + 7 + 7 + + + + + \ No newline at end of file diff --git a/scripts/netenter b/scripts/netenter new file mode 100755 index 0000000..1ce9346 --- /dev/null +++ b/scripts/netenter @@ -0,0 +1,16 @@ +#!/bin/bash + +# this is a script helps you to enter a network namespace +# dependency: ip unshare + +ns=$1 +shift +prog=${1:-bash} +shift + +if [ -z "$ns" ];
