The server uses "lwip" for client facing socket and "kernel tcp/ip stack " +as upstream server facing socket for UDP, "vpp-hoststack" for another updtream server facing stack for TCP. + +## Topology + + +## Steps +####1. Create VMs using vagrant. +Start demo VMs. Go to dmm/demo/nginx_proxy/demo-2 . +``` +$ vagrant up +``` +This command will create 4 VMs namely rproxy-client, rproxy-server1, rproxy-server2 and rproxy-proxy. The memory +requirement for this demo is 13GB (approx). + +####2. Log in to VMs +Open four terminal and login to VMs. +``` +$ vagrant ssh <vm-name> +``` + +####3. Run Udp server Application at rproxy-server2 +``` +$ vagrant ssh rproxy-server2 +Inside VM +vagrant@rproxy-server2:~$ sudo su +root@rproxy-server2:/home/vagrant# cd /UDPSERVER/ +root@rproxy-server2:/UDPSERVER# ./udpserver +``` + +####4. Run NGINX proxy server at rproxy-proxy +``` +$ vagrant ssh rproxy-proxy +Inside VM +vagrant@rproxy-proxy:~$ sudo su +root@rproxy-proxy:/home/vagrant# cd /DMM/thirdparty/apps/nginx/release +root@rproxy-proxy:/DMM/thirdparty/apps/nginx/release# export LD_LIBRARY_PATH=/DMM/stacks/lwip_stack/release/lib64 +root@rproxy-proxy:/DMM/thirdparty/apps/nginx/release# ./nginx +``` +####5. Test TCP traffic +``` +$ vagrant ssh rproxy-client +vagrant@rproxy-client:~$ cd /CLIENT/ +vagrant@rproxy-client:/CLIENT$ curl http://192.168.50.20 +Hello from upstream rproxy-server1 172.167.50.30:80. Connect from - via 172.167.50.20:15140 at [12/Nov/2018:06:17:25 -0800] GET / HTTP/1.1 200 0 curl/7.47.0 + +``` + +####6. Test UDP traffic +``` +$ vagrant ssh rproxy-client +vagrant@rproxy-client:~$ cd /CLIENT/ +vagrant@rproxy-client:/CLIENT$ curl http://192.168.50.20 +Hello message sent. +Server : Hello from server +``` +#### Notes: +a. If enable debugs i.e. export NSTACK_LOG_ON=DBG before we run nginx in rroxy-proxy we can find below logs which suggest we use diffrent stack for diffrent ip/protoccol. +``` +... +nstack_bind<NSSOC>fd addr Select module]fd=18,addr=192.168.50.20,module=lwip +... +nstack_bind<NSSOC>fd addr Select module]fd=22,addr=172.167.50.20,module=vpp_hoststack +... +nstack_bind<NSSOC>fd addr Select module]fd=22,addr=182.167.50.20,module=kernel +``` +b.
