Intelligent network traffic generator

Does anybody know of any intelligent network traffic generation software or hardware? I'm looking for something along the lines of SAST (Security Assessment Security Toolkit) that emulates the activities of human users on a network. The traffic generation need not be specifically for security testing.

Scapy's the closet thing that I know of. You're going to have to have some decent Python-fu and put in the work up-front though. You could also use tcprelay to replay tcpdump captures.

Would it be possible to use a couple of VMs and act like a user in them?

Yes, but I think he wants it automated.

I was also thinking you could use NMAP's NSE. You could either create a shell script that randomly/semi-randomly fires off a script, or you could create your own scripts.

Yeah, I really need a professional system like SAST or LARIAT or an Ixia Traffic Generator that can simulate enterprise-wide traffic. I'd just like to know if there are any alternatives to those.

I know this is an old Topic...

However, I'm looking for traffic generators and this was the closest thing I could find.

The first professional-grade products that come to my mind are Ixia's IxLoad (more complete, hardware-based) and IxChariot (lower cost, software-based).

I never did find a free or Open Source solution to this. It looks like hardware is needed to really provide the kind of control over traffic generation and monitoring that I needed at the time. Software-only solutions can mimic LAN usage in an office environment, but can't really extend to a good emulation of a corporate (enterprise) network.

I find it odd there's not a free script or something that'll generate "real" traffic.
