This manual page briefly documents the <b>tcprewrite</b> command. Tcprewrite is
a tool to rewrite packets stored in <i>pcap(3)</i> file format, such as crated
by tools such as <i>tcpdump(1)</i> and <i>ethereal(1)</i>. Once a pcap file
has had it's packets rewritten, they can be replayed back out on the network
using <i>tcpreplay(1)</i>.
<div style="height: 1.00em;"> </div>
tcprewrite currently supports reading the following DLT types:
<div style="height: 1.00em;"> </div>
<b>DLT_C_HDLC</b> aka Cisco HDLC
<div style="height: 1.00em;"> </div>
<b>DLT_EN10MB</b> aka Ethernet
<div style="height: 1.00em;"> </div>
<b>DLT_LINUX_SLL</b> aka Linux Cooked Socket
<div style="height: 1.00em;"> </div>
<b>DLT_RAW</b> aka RAW IP
<div style="height: 1.00em;"> </div>
<b>DLT_NULL</b> aka BSD Loopback
<div style="height: 1.00em;"> </div>
<b>DLT_LOOP</b> aka OpenBSD Loopback
<div style="height: 1.00em;"> </div>
<b>DLT_IEEE802_11</b> aka 802.11a/b/g
<div style="height: 1.00em;"> </div>
<b>DLT_IEEE802_11_RADIO</b> aka 802.11a/b/g with Radiotap headers
<div style="height: 1.00em;"> </div>
Please see the --dlt option for supported DLT types for writing.
<div style="height: 1.00em;"> </div>
The packet editing features of tcprewrite which distinguish between
"client" and "server" traffic requires a tcpprep(1) cache
file.
