NAME

       ipv6loganon - HTTP server log file anonymizer

SYNOPSIS

       ipv6loganon  [ -d value ] [ -V ] [ -n ] [ -w file ] [ -a file ] [ -c value ] [ --mask-ipv4
       bits ] [ --mask-ipv6 bits ] [ --no-mask-iid ] [ --anonymize-standard | --anonymize-careful
       | --anonymize-paranoid ]

DESCRIPTION

       ipv6loganon is a HTTP server log file anonymizer

       It expects a log line on stdin with an IPv4/IPv6 address as first token.

       This token would be anonymized according to given/default options.

       The anonymizer would keep as much information as possible for IPv6 address types.

       Client-side IID would be anonymized by

              • EUI-48 based: serial number would be zero'ed, keeping OID

              • EUI-64 based: serial number would be zero'ed, keeping OID

              • ISATAP: client IPv4 address would be anonymized by given IPv4 mask

              •  TEREDO:  client IPv4 address would be anonymized by given IPv4 mask, client port
              would be zero'ed

              • 6to4(Microsoft): client IPv4 address would be anonymized by given IPv4 mask

              • local: whole IID would be zero'ed (except if privacy extension was detected, then
              replaced by a special token)

       Client-side SLA would be anonymized by

              • SLA would be zero'ed

       Prefix would be anonymized by

              • 6to4: client IPv4 address would be anonymized by given IPv4 mask

       Compat/Mapped IPv4 addresses would be anonymized by

              • IPv4 address would be anonymized by given IPv4 mask

       Afterwards, the modified address and the trailing line would be printed to stdout or given
       file.

OPTIONS

   GENERAL
       -d, --debug <debug value>
              debug value (bitwise like)

       -V, --verbose
              be verbose

       -w, --write <file>
              write output to file instead of stdout

       -a, --append <file>
              append output to file instead of stdout

       -f, --flush
              flush output after each line

       -n, --nocache
              disable caching

       -c, --cachelimit
              set cache limit (default: 20, maximum: 200)

   OUTPUT ANONYMIZATION
       --mask-ipv4 <bits>
              mask all IPv4 addresses [0-32], default 24
               (applied also to IPv4 addresses inside IPv6 address)

       --mask-ipv6 <bits>
              mask IPv6 prefix [0-63], default 48
               (only applied to related address types)

       --no-mask-iid
              do not mask non-IPv4 based IPv6-IID

       --anonymize-standard
              (default) preset for standard anonymization
               mask-ipv4=24 mask-ipv6=48 mask-iid

       --anonymize-careful
              preset for careful anonymization
               mask-ipv4=20 mask-ipv6=40 mask-iid

       --anonymize-paranoid
              preset for paranoid anonymization
               mask-ipv4=16 mask-ipv6=32 mask-iid
