NAME
ipv6loganon - HTTP server log file anonymizer
SYNOPSIS
ipv6loganon [ -d value ] [ -V ] [ -n ] [ -c value ] [ --mask-ipv4 bits
] [ --no-mask-iid ] [ --anonymize-standard ]
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
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.
OPTIONS
GENERAL
-d, --debug <debug value>
debug value (bitwise like)
-V, --verbose
be verbose
-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 8 even if occurs in
IPv6-IID
--no-mask-iid
do not mask non-IPv4 based IPv6-IID
--anonymize-standard
preset for standard anonymization
Default settings: mask-ipv4=8 mask-iid
