Today we are releasing Tcpreplay suite version 4.5.1.
This release contains several bug fixes:
This release contains contributions from a record number of new contributors. This is greatly appreciated since I am a team of one, and do Tcpreplay maintenance in my spare time.
There are many bug fixes and new features. Most notable features:
- AF_XDP socket support - if you have a newer Linux kernel, you will be able to transmit at line rates without having to install 3rd party kernel modules (e.g. netmap, PF_RING)
-wtcpreplay option - this overrides the-ioption, and allows you to write to a PCAP file rather than an interface--includeand--excludetcpreplay options - allows replay of a list of specific packet numbers to replay. This may slow things down, so consider using in combination with-w.--fixhdrlentcpreplay option - added to control action on packet length changes-Wtcpreplay option - suppress warnings when replaying- SLL2( Linux “cooked” capture encapsulation v2)
- Haiku support
