Today we are releasing Tcpreplay suite version 4.5.1 <http://tcpreplay.appneta.com/wiki/installation.html#downloads>.
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) - -w tcpreplay option - this overrides the -i option, and allows you to write to a PCAP file rather than an interface - --include and --exclude tcpreplay options - allows replay of a list of specific packet numbers to replay. This may slow things down, so consider using in combination with -w. - --fixhdrlen tcpreplay option - added to control action on packet length changes - -W tcpreplay option - suppress warnings when replaying -
