icmpsh - simple reverse ICMP shell



icmpsh is a simple reverse ICMP shell with a win32 slave and a POSIX compatible master in C or Perl.





--- Running the Master ---



The master is straight forward to use. There are no extra libraries required for the C version. 

The Perl master however has the following dependencies:



	* IO::Socket

	* NetPacket::IP

	* NetPacket::ICMP





When running the master, don't forget to disable ICMP replies by the OS. For example:



	sysctl -w net.ipv4.icmp_echo_ignore_all=1



If you miss doing that, you will receive information from the slave, but the slave is unlikely to receive

commands send from the master.





--- Running the Slave ---



The slave comes with a few command line options as outlined below:





-t host            host ip address to send ping requests to. This option is mandatory!



-r                 send a single test icmp request containing the string "Test1234" and then quit. 

		   This is for testing the connection.



-d milliseconds    delay between requests in milliseconds 



-o milliseconds    timeout of responses in milliseconds. If a response has not received in time, 

		   the slave will increase a counter of blanks. If that counter reaches a limit, the slave will quit.

                   The counter is set back to 0 if a response was received.



-b num             limit of blanks (unanswered icmp requests before quitting



-s bytes           maximal data buffer size in bytes





In order to improve the speed, lower the delay (-d) between requests or increase the size (-s) of the data buffer.
