- Tcprewrite is a tool to rewrite packets stored in @file{pcap(3)} file format,
- such as crated by tools such as @file{tcpdump(1)} and @file{ethereal(1)}.
- Once a pcap file has had it's packets rewritten, they can be replayed back
- out on the network using @file{tcpreplay(1)}.
- tcprewrite currently supports the following DLT types:
- * DLT_C_HDLC
- * DLT_EN10MB
- * DLT_LINUX_SSL
- * DLT_RAW
- The packet editing features of tcprewrite which distinguish between "client"
- and "server" traffic requires a tcpprep(1) cache file.

- By default, tcprewrite uses the same DLT (data link type) for the
- output pcap as the input pcap. However, if you are changing the
- Layer 2 data with --dlink, then you probably also want to change the
- DLT type stored in the pcap. Common DLT types are:
- @table @bullet
- @item
- @var{0}
- No Layer 2 header (DLT_NULL)
- @item
- @var{1}
- Ethernet (DLT_EN10MB)
- @item
- @var{10}
- FDDI (DLT_FDDI)
- @item
- @var{12}
- BSD Raw header (DLT_RAW)
- @item
- @var{104}
- Cisco HDLC (DLT_C_HDLC)
- @item
- @var{113}
- Linux SLL pseudo-header (DLT_LINUX_SLL)
- For a full list of DLT types, see: src/common/dlt_names.h
