NFANON(1) General Commands Manual NFANON(1) NAME nfanon -- anonymize the IP addresses SYNOPSIS nfanon -r path [-w nffile] -K key [-q] [-h] DESCRIPTION nfanon anonimizes all IP addresses ( src, dst, next hop, router IP etc. ) in the netflow records using the CryptoPAn (Cryptography-based Pre- fix-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 https://en.wikipedia.org/wiki/Crypto-PAn for more information on Cryp- toPAn. The source specified by argument -r path may point to a single nfdump file or to a directory containing many nfdump files. All files in a directory are processed recursively. If the output argument -w nffile is given, all anonimized records are written into that single file, even if the source is a directory. If no argument -w is specified, nfanon overwrites the original source file with the anonymized flow records. If the source is a directory, each flow file is anonymized respectively. The options are as follows: -r path Path to read flow files to anonymize. Path may point to a sin- gle file or a directory containing many flow files. [-w nffile] File name to write anonymized flow records to. If this argument is missing, the source file name is taken, which means the original file is overwritten. -k key key is either a 32 character string, or a 64 char hex string starting with 0x. This key is used to initialize the anonymizer. -q nfanon prints the file name to be processed and an actifivy spinner. This option disables both. -h Print help text to stdout and exit. EXAMPLES To create a random 64 character hex string you may use the following command: % xxd -u -l 32 -p -c 64 /dev/urandom Use the resulting output as key, prepended with 0x as -K argument. RETURN VALUES nfanon returns 0 on success and 255 otherwise. SEE ALSO nfdump(1) FreeBSD Ports 14.quarterly $Mdocdate$ NFANON(1)
