1.Disable IPv6 for preventing TAP devices/bridges broadcasting routing:

• Step 1: Edit /etc/sysctl.conf (with sudo) and open the configuration file and add the following lines at the end:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

• Step 2: Type command sudo sysctl -p you will see this in terminal.

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

• Step 3: After that run $ cat /proc/sys/net/ipv6/conf/all/disable_ipv6 If it reports ‘1′ means you have disabled IPV6. If it reports ‘0‘ then please follow Step 2.

2.Compile Mininet

• Step 1: Move the opennet-agent.py into /usr/bin/:

sudo chmod 777 opennet-agent.py
sudo mv opennet-agent.py /usr/bin/

• Step 2: Install Mininet

./mininet/util/install.sh -a

You might need to delete pox/ and openflow/ if errors like "pox/openflow exists!" occur.

• Step 3: Go into the mininet subdirectory:

cd mininet/
sudo python setup.py install

3.Compile NS-3

• Step 1: Some preparations

sudo sh prepinstall.sh

• Step 2: Configuration

CXXFLAGS="-std=c++0x" ./waf configure --enable-sudo

• Step 3: Build

sudo ./waf build
sudo ./waf --apiscan=all
sudo ./waf install

4.Test

• Step 1: Open one terminal(named as T1), in T1 run:

sudo sh pre-config.sh

• Step 2: Open another terminal(named as T2), in T2 run:

cd examples/
sudo python one-switch-in-band-controller-csma.py

• Step 3: in T1 run:

sudo sh post-config.sh

• Step 4: in mininet running in T2 run:

xterm h4

A terminal window of h4 will be opened(named as T3). In T3 run:

cd ~/SDUWN/pox
./pox.py log.level --DEBUG forwarding.l2_learning

If there is no error, and you see:

INFO:openflow.of_01:[00-00-00-00-00-01 1] connected

then everything should be done.

Error: ImportError: libns3.25-core-debug.so: cannot open shared object file: No such file or directory

Solution:

• Step 1:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/sduwn/SDUWN/ns-allinone-3.25/ns-3.25/build

• Step 2:

sudo ldconfig

Error: RTNETLINK answers: File exists

Solution:

• Step1: Before test, run:

sudo mn -c
