	Mixed Packet Injector v2.45r-H2HC

I do appreciate any feedback, but I've been asking myself if you are really seriously writing this or just making a joke with all the list members... Did you bring the TCPREPLAY to this discussion??? I cannot imagine what kind of unsound mind could bring this comparison.

Two main factors led me to write this message:
1. TCPREPLAY and T50 have different approaches for different goals. How could you compare T50 to TCPREPLAY? T50 doesn't play with captured files (PCAP), in opposite T50 does play with its own packets and can be used to feed TCPREPLAY.
2. Do you really think packet_mmap could help any Stress Testing tool (Flooder and/or Packet Injector) to get a better performance? Delta calculation with random packet field? Come on... We are talking about different things here, aren't we?

And lastly, but not least, how could you pretend to do something to get a high-performance fashion playing with multi-core (multi-thread) if you are still limited by Kernel's network device queue??? Are you insane???

Please, you don't have to answer any of my questions... Please, don't. It could be much more embarrassing. 

T50 plays in an user level, and this was explained during the H2HC 7th Edition. The reason I did this is to show that cool things can be done in this space (user space), with no Kernel patch or Kernel driver module. The concept is not new, and I didn't say it is. IRC old-school (old is cool [?] =D) will remember all things I did with this code. T50 is the very first public tool applying multi-protocol injection using a single socket - AFAIK. That said, how you dare to compare T50 and TCPREAPLY? I am not a TCPREPLAY expert, but I am not aware of any feature of TCPREPLAY that makes it able to inject packet without a PCAP file.

I do refuse myself to enter in another battle, but do you really believe on what you said?

I will not explain anything else to you, if you want to see the slide-desk, be my guest:
http://www.slideshare.net/nbrito01/the-hangover-a-modern-high-performance-approach-to-build-an-offensive-computing-tool

BTW, if you really think I have to give you any credit, please, give me evidences of something I should give credit to you or to anybody else, a credit other than: "you are an excellent and freaking great Internet troll". Otherwise, please, just stop trolling me with all your frustration and find something really interesting to do with your life...

I don't see the "wow" factor from this tool? Perhaps I forgot to take my "super l33t" pills, but I fail to see how this is different from something like tcpreplay, which not only does any packet(s) desired, but can pull them from an existing packet capture (and even edit those packets on the fly) allowing one to truly customize the traffic as much as possible. Additionally, I looked at this tool hoping for some "exciting" new code, but found nothing which people writing router / gateway software haven't known for years. In fact, you didn't even do intelligent checksum recalculation (ie: store a "base" checksum somewhere, and just do some quick delta calculation on it), and you didn't take advantage of packet_mmap on linux (zero copy seems like good juju for high-speed network transmission); HECK you're running from a single context of execution, instead of trying to execute on all available cores (which could add some scalability, depending on the architecture). 

I don't want to sound like I'm a total negative nancy - and certainly security is a hobby domain, not my primary area of expertise, but you posted this to a publicly available forum, so I suppose you were looking for some type of vetting, criticism, and feedback. My feedback would be to contribute to tcpreplay. There's nothing that your tool offers as an advantage (from a cursory glance, your tool appears to be hping --flood) to any available options; there's nothing unique that I saw.

Additionally, my noscript caught a click-jacking attempt from your homepage when I went to download the file. I might suggest a better file serving mechanism.

Subject: [Dailydave] [TOOL RELEASE] T50 Sukhoi PAK FA Mixed Packet Injector v2.45r-H2HC

T50 Sukhoi PAK FA Mixed Packet Injector (f.k.a. F22 Raptor) is a tool
designed to perform "Stress Testing". It is a powerful and an unique packet
injection tool, that is capable of:
1. Send sequentially (i.e., ALMOST on the same time) the following
protocols:
  - ICMP: Internet Control Message Protocol
  - IGMP: Internet Group Management Protocol
  - TCP:  Transmission Control Protocol
  - UDP:  User Datagram Protocol

2. Send an (quite) incredible amount of packets per second, making it a
“second to none” tool:
  - More than 1,000,000 pps of SYN Flood (+50% of the network’s uplink) in
a 1000BASE-T Network (Gigabit Ethernet).
  - More than 120,000 pps of SYN Flood (+60% of the network’s uplink) in a
100BASE-TX Network (Fast Ethernet).

3. Perform “Stress Testing” on a variety of network infrastructure, network
devices and security solutions in place.

4. Simulate Denial-of-Service attacks, validating the Firewall rules and
Intrusion Detection System/Intrusion Prevention System policies.

Further information can be found @ http://fnstenv.blogspot.com (demo video
and source code).

PS: Yes, there are some "anti-kiddo" tricks, so, please, don't blame me for
doing that...

The new version of the "T50 Sukhoi PAK FA Mixed Packet Injector" (v5.2-NG)
will be unleashed on "WEB Security Forum" (http://websecforum.com.br/evento/
/ April 9th-10th 2011 / São Paulo, Brazil).

The next release will include:
1. New License: It is still not licensed under GPL or any other common
Open-source license, but the source code will be available and the use of
any piece of source code for any free or commercial software is denied.

2. CIDR Support: Classless Inter-Domain Routing support for destination IP
address, using a really tiny C algorithm. This would allow the "T50 Sukhoi
PAK FA Mixed Packet Injector" to simulate DDoS in a laboratory environment.

  001 netmask = ~(0xffffffff>>cidr);
  002 hostid = (int)(pow(2,(32-cidr))-2);
  003 __1st_host = (ntohl(addr)&netmask)+1;
  004 __lst_host = (ntohl(addr)&netmask)+hostid;

3. TEN NEW Protocols: TEN (10) more protocols supported by "T50 Sukhoi PAK
FA Mixed Packet Injector" (IGMPv3, EGP, DCCP, RSVP, RIPv1, RIPv2, GRE, ESP,
AH and EIGRP).

4. Exotic Protocols: Advanced options and protocol crafting for EIGRP and
GRE were added, allowing users to make any combination while using those
exotic protocols. By the way, EIGRP is a proprietary protocol developed by
CISCO Systems, Inc.

5. TCP Options Support: TCP Options (MSS, NOP, EOL, WSCALE, TSTAMP, T/TCP CC
and SACK) are supported to improve the TCP protocol.

6. DATA Payload Support: The data payload support is back, and it can be
rand or user defined.

Best regards.
