NAME

       nfanon - netflow anonymisation

SYNOPSIS

       nfanon [options]

DESCRIPTION

       nfanon  is  used  to  anonymise  all  IP  addresses ( src, dst, next hop, router IP etc. ) in the netflow
       records using the CryptoPAn (Cryptography-based  Prefix-preserving Anonymization) module. The key  -K  is
       used  to  initialize  the  Rijndael  cipher.   The key is either a 32 character string, or a 64 hex digit
       string starting with 0x.

          See http://www.cc.gatech.edu/computing/Telecomm/cryptopan/ for more information about CryptoPAn.

       nfanon has several modes of operation.

       o nfanon reads a sequence of input files, specified by -r, -R and -M and  anonymises  the  flows  in  the
       given files. The input file arguments have the same syntax and meaning as nfdump(1).

       o  nfanon  reads a sequence of input files, specified by -r, -R and -M.  All anonymised flows are written
       to a single file specified by -w.

       o nfanon works as filter and reads flows from stding and writes the anonymised flows to stdout.

OPTIONS

       -r inputfile
          Read input data from inputfile. Default is read from stdin.

       -R expr
          Read input from a sequence of files in the same directory. expr may be one of:
           /any/dir          Read recursively all files in directory dir.
           /dir/file         Read all files beginning with file.
           /dir/file1:file2  Read all files from file1 to file2.

           Note: files are read in alphabetical sequence.

       -M expr
          Read input from multiple directories. expr looks like: /any/path/to/dir1:dir2:dir3 etc.  and  will  be
          expanded  to the directories: /any/path/to/dir1, /any/path/to/dir2 and /any/path/to/dir3 Any number of
          colon separated directories may be given. The files to read are specified by -r or -R and are expected
          to exist in all the given directories.  The options -r and -R must not contain any directory part when
          used in conjunction with -M.

       -w outputfile
          If specified writes anonymised netflow records to outputfile.

       -K key
          The key is used to initialize the Rijndael cipher. key is either a 32 character string, or  a  64  hex
          digit string starting with 0x.

RETURN VALUE

       Returns
           0   No error.
           255 Initialization failed.
           250 Internal error.

NOTES

       None.
