Hi,

I did not install awk myself as it is ready to use in most Linux distributions.

If your Linux system does not have it, you can refer to http://www.gnu.org/software/gawk/ to install awk.

1) sudo apt-get install gawk

2) cd /usr/bin/ && sudo ln -s gawk awk

@ mleoking
Add the following lines to the end of ns-default.tcl ("ns-allinone-2.33\ns-2.33\tcl\lib\ns-default.tcl").
# Added by leoking spoof config 0
Agent/TCP set saddr_min 1
Agent/TCP set saddr_max 100
Agent/TCP set spoof_level 0

Agent/UDP set saddr_min 1
Agent/UDP set saddr_max 100
Agent/UDP set spoof_level 0
# Added by leoking spoof config 1

this was not helpful in solving the warning problem

Did you get the statistical results like the following:

rate_f1_normal 650.840000 rate_f1_attack 619.410000 nth_f1 0.951709
rate_f2_normal 0.000000 rate_f2_attack 12601.000000 nth_f2

It seems to me that your warning "warning: no class variable Agent/TCP/Newreno::saddr_max" means that you have not finished the steps in integration-of-ip-spoofing.txt. I attached a new version of "integration-of-ip-spoofing.txt" to this thread:

1. Copy the following files into the directory "ns-allinone-2.33\ns-2.33\common".
agent-leo.h
agent-leo.cc

2. Modify tcp.h ("ns-allinone-2.33\ns-2.33\tcp\tcp.h")
2.1. Insert the following line of code after [#include "agent.h"]:
#include "agent-leo.h"
2.2. Replace "public Agent" with "public LeoAgent"

3. Modify tcp.cc ("ns-allinone-2.33\ns-2.33\tcp\tcp.cc")
3.1. Replace "Agent(PT_TCP)" with "LeoAgent(PT_TCP)"
3.2. Replace "Agent::command(argc, argv)" with "LeoAgent::command(argc, argv)"

4. Modify udp.h ("ns-allinone-2.33\ns-2.33\apps\udp.h")
2.1. Insert the following line of code after [#include "agent.h"]:
#include "agent-leo.h"
2.2. Replace "public Agent" with "public LeoAgent"

5. Modify udp.cc ("ns-allinone-2.33\ns-2.33\apps\udp.cc")
3.1. Replace "Agent(PT_UDP)" with "LeoAgent(PT_UDP)"
3.2. Replace "Agent(type)" with "LeoAgent(type)"
3.3. Replace "Agent::command(argc, argv)" with "LeoAgent::command(argc, argv)"

6. Add the following lines to the end of ns-default.tcl ("ns-allinone-2.33\ns-2.33\tcl\lib\ns-default.tcl").
# Added by leoking spoof config 0
Agent/TCP set saddr_min 1
Agent/TCP set saddr_max 100
Agent/TCP set spoof_level 0

Agent/UDP set saddr_min 1
Agent/UDP set saddr_max 100
Agent/UDP set spoof_level 0
# Added by leoking spoof config 1

7. Insert the following line of code before "$(OBJ_STL)" in the Makefile ("ns-allinone-2.33\ns-2.33\Makefile"):
common/agent-leo.o \

8. Recompile the ns-allinone-2.33 system by using the following commands (you should execute these commands in the ns-2.33 directory "ns-allinone-2.33\ns-2.33"):
make clean
make depend
make

Have finished all of the above steps, particular steps 2, 3, 4, 5. Also for the last step, say recompile the ns system, you need to make sure that the ns system is really recompiled. Sometimes, you have to delete all the *.o files and synchronize the time mark of all the files using these two commands:

rm *.o
touch *

under these directories:

ns-allinone-2.33\ns-2.33\common
ns-allinone-2.33\ns-2.33\tcp
ns-allinone-2.33\ns-2.33\apps

and do step8 again to force the ns system to be recompiled.

8. Recompile the ns-allinone-2.33 system by using the following commands (you should execute these commands in the ns-2.33 directory "ns-allinone-2.33\ns-2.33"):
make clean
make depend
make

Hope this helps.

integration-of-ip-spoofing.txt (3.9 KB, 33 views)

I just tried the integration process of ip spoofing support in my ns2 and found there was no warning after finishing the steps in "integration-of-ip-spoofing.txt". It worked fine.

It is worth noting that you need to check whether there is a file named "agent-leo.o" in the directory of "ns-allinone-2.33\ns-2.33\common" after you finish the integration of ip spoofing.

If there is not such a file, your ns was not really recompiled. You need to force it to recompile using the ways in my last threat.

when i try to make it
it gives me following error
./common/packet.h:258:26: warning: deprecated conversion from string constant to ‘char*’

also the file agent-leo.o is not in my common folder
there are files
agent-leo.cc
agent-leo.h

@mleoking
suggest some help

Hi,

The error "apps/udp.cc:67:37: error: type ‘Agent’ is not a direct base of ‘UdpAgent’" shows that you might have not finished the step:

5.2. Replace "Agent(type)" with "LeoAgent(type)" in

5. Modify udp.cc ("ns-allinone-2.33\ns-2.33\apps\udp.cc")
5.1. Replace "Agent(PT_UDP)" with "LeoAgent(PT_UDP)"
5.2. Replace "Agent(type)" with "LeoAgent(type)"
5.3. Replace "Agent::command(argc, argv)" with "LeoAgent::command(argc, argv)"

I have compared the following files between ns2.32 and ns2.33:
agent.cc agent.h tcp.cc tcp.h udp.cc udp.h
And found that agent.cc, agent.h, udp.cc, udp.h are actually exactly the same between ns2.32 and ns2.33. There are minor modifications in tcp.cc and tcp.h in ns2.33 compared to that of ns2.32. I believe the steps in "integration-of-ip-spoofing.txt" can also be applied to ns2.32.

You need to double check if you have completely followed the steps in "integration-of-ip-spoofing.txt".

It is also worth noting that the overwriting method mentioned at the end of the "integration-of-ip-spoofing.txt" might only be applied to ns2.33. Since you are using ns2.32, you should manually finish all the steps in "integration-of-ip-spoofing.txt" rather than directly overwrite udp.cc, udp.h, tcp.cc, tcp.h with the files provided in the AQM&DoS package.

Good luck to you.

I hope you have fixed you problem.

FYI, a slightly modified version (1.1) of AQM&DoS Simulation Platform is released. It mainly aims to simplify the steps of integrating the ip spoofing support. You could download it from here:

http://sites.google.com/site/cwzhang...lationplatform

The new steps are:

The ip spoofing function can be integrated into the NS2 distributions in these steps:
1. Copy the following files into the directory "ns-allinone-2.33\ns-2.33\common".
agent-leo.h

2. Modify agent.h ("ns-allinone-2.33\ns-2.33\common\agent.h")
2.1. Insert the following line of code in a new line before "class Application;":
#include "agent-leo.h" //Added by leoking
2.2. Replace "class Agent : public Connector {" with "class Agent : public Connector, public AgentLeo {//Modified by leoking"

3. Modify agent.cc ("ns-allinone-2.33\ns-2.33\common\agent.cc")
3.1. Insert the following line of code into the function body of "Agent::Agent(packet_t pkttype)":
init_agent_leo();//Added by leoking
3.2. Insert the following line of code into the end of the function body of "Agent::initpkt(Packet* p)":
initpkt_after(p); //Added by leoking

4. Add the following lines to the end of ns-default.tcl ("ns-allinone-2.33\ns-2.33\tcl\lib\ns-default.tcl"):
# Added by leoking spoof config 0
Agent set saddr_min_ 1
Agent set saddr_max_ 100
Agent set spoof_level_ 0
# Added by leoking spoof config 1

5. Recompile the ns-allinone-2.33 system by using the following commands (you should execute these commands in the ns-2.33 directory "ns-allinone-2.33\ns-2.33"):
make clean
make depend
make

But, for ns-2.33 and ns-3.2, you do not need to manually do step 2 and 3, you could simply use agent.h and agent.cc provided in the package to overwrite their corresponding files in the NS2 distribution.
But you still need to finished step 1, 4 and 5.

You can continue using the AQM&DoS Simulation Platform that you had got (version 1.0) and fix your problems according to my previous threat.

Or you can choose to use the new version 1.1. But, as you have modified tcp.cc, tcp.h, udp.cc and udp.h according to the instructions of the old version of AQM&DoS, you need to use the original files (tcp.cc, tcp.h, udp.cc and udp.h) from the your ns distribution to overwrite the modified files before you start using the AQM&DoS 1.1.

If you did not backup the original files (tcp.cc, tcp.h, udp.cc and udp.h) of your ns, you can find them here:

hi
my project is simulating ddos in ns2
would you please help me
I am new in that
please help me

Hey, have a look at the AQM&DoS Simulation Platform.

I think it is what you need.

Hi i have to simulate DDoS and in ns2 ...and then have to genrate the graph using xgraph....i want to check the packet loss...acknowledgements...bandwidth and delays........at specific time interval.......how i can do this...????
what i have done yet is that i have simulated the DDoS but dnt know how to generate these different graphs and how to do their analysis...
Any idea.........i am using NS2 for the first time......Thanks in Advance...
