5 ipresend \- resend IP packets out to network
25 \fBipresend\fP was designed to allow packets to be resent, once captured,
26 back out onto the network for use in testing. \fIipresend\fP supports a
27 number of different file formats as input, including saved snoop/tcpdump
32 Set the interface name to be the name supplied. This is useful with the
33 \fB\-P, \-S, \-T\fP and \fB\-E\fP options, where it is not otherwise possible
34 to associate a packet with an interface. Normal "text packets" can override
38 Specify the hostname of the gateway through which to route packets. This
39 is required whenever the destination host isn't directly attached to the
40 same network as the host from which you're sending.
43 Specify the MTU to be used when sending out packets. This option allows you
44 to set a fake MTU, allowing the simulation of network interfaces with small
45 MTU's without setting them so.
48 Specify the filename from which to take input. Default is stdin.
51 The input file is to be text output from etherfind. The text formats which
52 are currently supported are those which result from the following etherfind
62 The input file is to be hex digits, representing the binary makeup of the
63 packet. No length correction is made, if an incorrect length is put in
67 The input file specified by \fB\-i\fP is a binary file produced using libpcap
68 (i.e., tcpdump version 3). Packets are read from this file as being input
72 When sending packets out, send them out "raw" (the way they came in). The
73 only real significance here is that it will expect the link layer (i.e.
74 ethernet) headers to be prepended to the IP packet being output.
77 The input file is to be in "snoop" format (see RFC 1761). Packets are read
78 from this file and used as input from any interface. This is perhaps the
79 most useful input type, currently.
82 The input file is to be text output from tcpdump. The text formats which
83 are currently supported are those which result from the following tcpdump
96 The input file is composed of text descriptions of IP packets.
99 ipftest(1), ipsend(1), iptest(1), bpf(4), ipsend(5), tcpdump(8)
102 Needs to be run as root.
105 Not all of the input formats are sufficiently capable of introducing a
106 wide enough variety of packets for them to be all useful in testing.
