.SH DESCRIPTION
|
|
\fBipresend\fP was designed to allow packets to be resent, once captured,
|
|
back out onto the network for use in testing. \fIipresend\fP supports a
|
|
number of different file formats as input, including saved snoop/tcpdump
|
|
binary data.
|
|
.SH OPTIONS
|
|
.TP
|
|
.BR \-d \0<interface>
|
|
Set the interface name to be the name supplied. This is useful with the
|
|
\fB\-P, \-S, \-T\fP and \fB\-E\fP options, where it is not otherwise possible
|
|
to associate a packet with an interface. Normal "text packets" can override
|
|
this setting.
|
|
.TP
|
|
.BR \-g \0<gateway>
|
|
Specify the hostname of the gateway through which to route packets. This
|
|
is required whenever the destination host isn't directly attached to the
|
|
same network as the host from which you're sending.
|
|
.TP
|
|
.BR \-m \0<MTU>
|
|
Specify the MTU to be used when sending out packets. This option allows you
|
|
to set a fake MTU, allowing the simulation of network interfaces with small
|
|
MTU's without setting them so.
|
|
.TP
|
|
.BR \-r \0<filename>
|
|
Specify the filename from which to take input. Default is stdin.
|
|
.TP
|
|
.B \-E
|
|
The input file is to be text output from etherfind. The text formats which
|
|
are currently supported are those which result from the following etherfind
|
|
option combinations:
|
|
.PP
|
|
.nf
|
|
etherfind -n
|
|
etherfind -n -t
|
|
.fi
|
|
.LP
|
|
.TP
|
|
.B \-H
|
|
The input file is to be hex digits, representing the binary makeup of the
|
|
packet. No length correction is made, if an incorrect length is put in
|
|
the IP header.
|
|
.TP
|
|
.B \-P
|
|
The input file specified by \fB\-i\fP is a binary file produced using libpcap
|
|
(i.e., tcpdump version 3). Packets are read from this file as being input
|
|
(for rule purposes).
|
|
.TP
|
|
.B \-R
|
|
When sending packets out, send them out "raw" (the way they came in). The
|
|
only real significance here is that it will expect the link layer (i.e.
|
|
ethernet) headers to be prepended to the IP packet being output.
|
|
.TP
|
|
.B \-S
|
|
The input file is to be in "snoop" format (see RFC 1761). Packets are read
|
|
from this file and used as input from any interface. This is perhaps the
|
|
most useful input type, currently.
|
|
.TP
|
|
.B \-T
|
|
The input file is to be text output from tcpdump. The text formats which
|
|
are currently supported are those which result from the following tcpdump
|
|
option combinations:
|
|
.PP
|
|
.nf
|
|
tcpdump -n
|
|
tcpdump -nq
|
|
tcpdump -nqt
|
|
tcpdump -nqtt
|
|
tcpdump -nqte
|
|
.fi
|
|
.LP
|
|
.TP
|
|
.B \-X
|
|
The input file is composed of text descriptions of IP packets.
|
|
.DT
|
|
.SH SEE ALSO
|
|
snoop(1m), tcpdump(8), etherfind(8c), ipftest(1), ipresend(1), iptest(1), bpf(4), dlpi(7p)
|
|
.SH DIAGNOSTICS
|
|
Needs to be run as root.
|
|
.SH BUGS
|
|
Not all of the input formats are sufficiently capable of introducing a
|
|
wide enough variety of packets for them to be all useful in testing.
