Captive Portal for ID-based Network on mininet

Files

Apache server IP: Add "ServerName 192.168.44.200" in apache2.conf and default-ssl.conf.

$ sudo vim /etc/apache2/apache2.conf
in /etc/apache2/apache2.conf
219 # vim: syntax=apache ts=4 sw=4 sts=4 sr noet
220 ServerName 192.168.44.200

$ sudo vim /etc/apache2/sites-available/default-ssl.conf
in /etc/apache2/sites-available/default-ssl.conf
3 ServerAdmin webmaster@localhost
4 ServerName 192.168.44.200
5 DocumentRoot /var/www/html

Replace the content of 000-default.conf, with that of httpd.conf.

$ sudo cp ~/ID-based-master/httpd.conf /etc/apache2/sites-available/httpd.conf
$ sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/000-default.conf.bak
$ sudo cp /etc/apache2/sites-available/httpd.conf /etc/apache2/sites-available/000-default.conf

You can find how to setup the environment in step 1 and 2 on (https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-16-04), (https://www.digitalocean.com/community/tutorials/how-to-create-a-self-signed-ssl-certificate-for-apache-in-ubuntu-16-04), and (https://www.digitalocean.com/community/tutorials/how-to-create-a-ssl-certificate-on-apache-for-ubuntu-14-04).

Copy Login directory to /var/www/html.

$ cd ID-based-master
$ sudo cp -r Login /var/www/html/Login

Create database and tables.

mysql> CREATE DATABASE portal CHARACTER SET utf8 COLLATE utf8_general_ci;
$ mysql -uroot -p<password> -Dportal<~/ID-based-master/portal.sql

Usage

Start ONOS.

$ cd $ONOS_ROOT
$ bazel run onos-local -- clean     # ok clean

Compile all ID-based applications and install them.

$ cd iacl-app/      # take `iacl-app` for example
$ mvn clean install -DskipTests
$ onos-app localhost install target/iacl-app-1.10.0.oar

Tell the ovsdb server to start listening on port 6640.

$ sudo ovs-vsctl set-manager tcp:127.0.0.1:6640

Activate ovsdb app and driver on ONOS.

onos> app activate org.onosproject.ovsdb org.onosproject.drivers.ovsdb

You can find step 3 and 4 on ONOS Wiki.

Modify default drivers for OVSDB ($ONOS_ROOT/drivers/ovsdb/src/main/resources/ovsdb-drivers.xml) to enable QoS and Queue API. Add following line at the default driver.

        <behaviour api="org.onosproject.net.behaviour.QosConfigBehaviour"
                   impl="org.onosproject.drivers.ovsdb.OvsdbQosConfig"/>
        <behaviour api="org.onosproject.net.behaviour.QueueConfigBehaviour"
                   impl="org.onosproject.drivers.ovsdb.OvsdbQueueConfig"/>

Step 3 to 5 are required by the ibwd-app application.

Activate all ID-based applications on ONOS.

onos> app activate iacl.app ibwd.app ifwd.app

Configure ONOS.

$ onos-netcfg localhost net_config.json

Run access_db.

$ sudo python access_db.py

Run mininet.

$ sudo python topo.py

Captive Portal for ID-based Network on multiple VMs and physical switch

There are five virtaul machines and one switch.

ID-based-web (ct) IP = 192.168.20.xxx vlan 20 (for Internet) IP = 192.168.44.101 (for Intranet)
ID-based-portal (ct) IP = 192.168.44.200
ID-based-dhcp (ct) IP = 192.168.44.201
ID-based-controller (vm) IP = 192.168.20.xxx vlan 20 (for controll plane) IP = 192.168.44.128 (for data plane)
ID-based-host (vm) IP = dynamic IP
Switch (switch) IP = 192.168.20.203 ID = "of:000078321bdf7000"

ID-based-web

It's a web server and a router.

Configure iptables

$ iptables -t nat -A POSTROUTING -s 192.168.44.0/24 -o eth1 -j MASQUERADE
$ iptables -t filter -A FORWARD -i eth0 -o eth1 -j ACCEPT
$ iptables -t filter -A FORWARD -i eth1 -o eth0 -j ACCEPT

Save iptables

$ iptables-save > /etc/iptables_rules

Make web always start iptables and IPv4 routing on boot

$ vim /etc/rc.local
in /etc/rc.local

        echo "1" > /proc/sys/net/ipv4/ip_forward
        /sbin/iptables-restore < /etc/iptables_rules
        exit 0

Run simple web server in background on port 80

$ python -m SimpleHTTPServer 80 &

ID-based-portal

Enable SSL on the apache server.

$ vim /etc/apache2/sites-available/default-ssl.conf
in /etc/apache2/sites-available/default-ssl.conf
3 ServerAdim webmaster@localhost
4 ServerName 192.168.44.200

You can find step 1 on (https://www.digitalocean.com/community/tutorials/how-to-create-a-self-signed-ssl-certificate-for-apache-in-ubuntu-16-04).

Copy httpd.conf to replace 000-default.conf

$ cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/000-default.conf.bak
$ cp /etc/apache2/sites-available/httpd.conf /etc/apache2/sites-available/000-default.conf

Make apache server listen on port 3000

$ vim /etc/apache2/ports.conf
in /etc/apache2/ports.conf
5 Listen 80
6 Listen 3000

Open port 3000 on firewall

$ ufw allow 3000/tcp

Restart apache server

$ systemctl restart apache2

ID-based-dhcp

Create a subnet for DHCP server.

$ vim /etc/dhcp/dhcpd.conf
in /etc/dhcp/dhcpd.conf
63 subnet 192.168.44.0 netmask 255.255.255.0 {
64      range 192.168.44.160 192.168.44.180;
65      option domain-name-servers 8.8.8.8;
66      option subnet-mask 255.255.255.0;
67      option broadcast-address 192.168.44.255;
68      default-lease-time 20;
69      max-lease-time 60;
70 }

Configure which interface it should serve.

$ vim /etc/default/isc-dhcp-server
in /etc/default/isc-dhcp-server
21 INTERFACES="eth0"

Restart DHCP server.

$ systemctl restart isc-dhcp-server

Activate three apps and ovsdb

$ onos localhost app activate org.onosproject.ovsdb org.onosproject.drivers.ovsdb org.ifwd.app org.ibwd.app org.iacl.app

Upload configuration JSON file

$ onos-netcfg localhost new_net_config.json

Start accessdb api

$ sudo python ID-based-master/accessdb.py

ID-based-host

Use browser connect to http://192.168.44.101
It will be redirected to portal(http://192.168.44.200:3000)
Enter username and password(ex: 1, 1)
If authentication is successful, then you can access http://192.168.44.101
