.SH DESCRIPTION
|
|
.PP
|
|
\fBipsend\fP can be compiled in two ways. The first is used to send one-off
|
|
packets to a destination host, using command line options to specify various
|
|
attributes present in the headers. The \fIdestination\fP must be given as
|
|
the last command line option, except for when TCP flags are specified as
|
|
a combination of A, S, F, U, P and R, last.
|
|
.PP
|
|
The other way it may be compiled, with DOSOCKET defined, is to allow an
|
|
attempt at making a TCP connection using a with ipsend resending the SYN
|
|
packet as per the command line options.
|
|
.SH OPTIONS
|
|
.TP
|
|
.BR \-d
|
|
enable debugging mode.
|
|
.TP
|
|
.BR \-f \0<offset>
|
|
The \fI-f\fP allows the IP offset field in the IP header to be set to an
|
|
arbitrary value, which can be specified in decimal or hexidecimal.
|
|
.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 \-i \0<interface>
|
|
Set the interface name to be the name supplied.
|
|
.TP
|
|
.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 \-o \0<option>
|
|
Specify options to be included at the end of the IP header. An EOL option
|
|
is automatically appended and need not be given. If an option would also
|
|
have data associated with it (source as an IP# for a lsrr option), then
|
|
this will not be initialised.
|
|
.TP
|
|
.BR \-s \0<source>
|
|
Set the source address in the packet to that provided - maybe either a
|
|
hostname or IP#.
|
|
.TP
|
|
.BR \-t \0<dest. port>
|
|
Set the destination port for TCP/UDP packets.
|
|
.TP
|
|
.BR \-w \0<window>
|
|
Set the window size for TCP packets.
|
|
.TP
|
|
.B \-I
|
|
Set the protocol to ICMP.
|
|
.TP
|
|
.B \-P <protocol>
|
|
Set the protocol to the value given. If the parameter is a name, the name
|
|
is looked up in the \fI/etc/protocols\fP file.
|
|
.TP
|
|
.B \-T
|
|
Set the protocol to TCP.
|
|
.TP
|
|
.B \-U
|
|
Set the protocol to UDP.
|
|
.TP
|
|
.BR \-d
|
|
enable verbose mode.
