SYNOPSIS

10       fragrouter6 [-dv -f len -e count -t count] INTERFACE EVASION-METHOD

OPTIONS

14         -f len    size of mini fragments (option 64, default 8)
15         -e count  hop count to the IDS for evading (option 256 & 512)
16         -t count  hop count to the target that reaches it
17         -v        verbose mode, print all packets processed for evasion
18

Evasion Methods

20         0     no manipulation
21         1-31  the number of atomic fragmentation headers to insert
22         32    use destination headers for 1-31 instead of fragmentation head‐
23       ers
24         64    fragment each packet to 8 byte length pieces  (or  change  with
25       -f)
26         128   a large destination header that fragments the packet
27         256   insert fake TCP data with a hop count just for the IDS (-e)
28         512   insert TCP connection reset packet with a hop count just to the
29       IDS (-e)
30        1024   insert fake fragmentation data with a hop count  just  for  the
31       IDS (-e)
32        2048   insert faked seq/ack data TCP packet
33
34       Performs  NIDS/NIPS  evasion to all defined packets that originate from
35       your system or pass through it. All evasion  methods  can  be  combined
36       (add together) with the exception that only either one of 64 or 128 can
37       be used at once.  Option 1024 can be used with 1..31 and 64.  The  eva‐
38       sion  methods  are  processed  in  the following order: 256, 512, 2048,
39       1..31/33..63 then either 64 or 128  then  1024.   Requires  to  set  up
40       ip6table  rules  that  jump  to  NFQUEUE, use fragrouter6.sh which is a
41       wrapper for ip6tables and fragrouter6!
