Well things have stablized enough I think to start getting other people's feedback on the new 3.0 branch to release 3.0 Beta 1. For those of you not familar with it, tcpreplay is a suite of BSD licensed tools for *NIX operating systems (although there is a Win32 port) which gives you the ability to use previously captured traffic in libpcap format to test a variety of network devices. It allows you to classify traffic as client or server, rewrite Layer 2, 3 and 4 headers and finally replay the traffic back onto the network and through other devices such as switches, routers, firewalls, NIDS and IPS's. What's new you ask? Well plenty... The biggest change is all the packet editing code has been moved to a new application called tcprewrite. This should hopefully make things simpler and easier to use, but definately will improve replay speed. As a matter of fact, even if you're not editing packets, 3.0 should be faster then 2.3.3. The other big change is using GNU Autogen/Autoopts for processing the command line and config files. Also, since the man pages are built directly from the code, they should always be accurate and up to date. Note: flowreplay does not currently use Autoopts, so the man page is inaccurate. But since flowreplay is still in alpha and doesn't really work, I'm not worrying about it too much. :) Anyways, most of all the features from 2.3.3 should be working in this Beta, but a few like bridge mode have been pulled for now. If your favorite feature isn't in Beta 1, drop me a line and I'll make sure it's back in Beta 2. I've worked on updating the FAQ and have started a real manual, but both still need work to be complete and accurate. The man pages are pretty good though. If you've got questions, please email the list. If you want to take a peek, it's all posted on the website. Lastly, I'm asking for comments on wether or not tcpreplay should ship with libnet and libpcap. A lot of people it seems have problems linking tcpreplay with libnet and libpcap (often because they have multiple versions installed) or have problems with running an older version which is less then ideal for tcpreplay. The advantage of course is that these problems go away. The disadvantage is that the tarball will be bigger and compile time will longer too. I'd rather not do this since it's just more work for me, but I get enough questions about it where I'm open to the idea.
