traceanon
TRACEANON(1) User Commands TRACEANON(1)
NAME
traceanon - anonymise ip addresses of traces
SYNOPSIS
traceanon [ -s | --encrypt-source ] [ -d | --encrypt-dest ] [ -p prefix | --prefix=prefix ] [ -c key | --cryptopan=key ] [ -f key-file |
--keyfile=file ] [ -z level | --compress-level=level ] [ -Z method | --compress-type=method ] sourceuri desturi
DESCRPTION
traceanon anonymises a trace by replacing IP addresses found in the IP header, and any embedded packets inside an ICMP packet. It also
fixes the checksums inside TCP and UDP headers.
Two anonymisation schemes are supported, the first replaces a prefix with another prefix. This can be used for instance to replace a /16
with the equivilent prefix from RFC1918. The other scheme is cryptopan which is a prefix preserving encryption scheme based on AES.
-s
--encrypt-source
encrypt only source ip addresses.
-d
--encrypt-dest
encrypt only destination ip addresses.
-p
--prefix=prefix
substitute the high bits of the IP addresses with the provided prefix.
-c
--cryptopan=key
encrypt the IP addresses using the prefix-preserving cryptopan method using the key "key". The key can be up to 32 bytes long, and
will be padded with NULL characters.
-f
--keyfile=file
encrypt the IP addresses using the prefix-preserving cryptopan method using the key specified in the file "file". The key must be
32 bytes long. A suitable method of generating a key is by using the command dd to read from /dev/urandom.
-z
--compress-level=level
compress the output trace using a compression level of "level". Compression level can range from 0 (no compression) through to 9.
Higher compression levels require more CPU to compress data. Defaults to no compression.
-Z
--compress-type=method
compress the output trace using the compression algorithm "method". Possible algorithms are "gzip", "bzip2", "lzo" and "none".
Default is "none".
EXAMPLES
traceanon --cryptopan="fish go moo, oh yes they do"
--encrypt-source
--encrypt-dest
--compress-level=1
--compress-type=gzip
erf:/traces/unenc.gz
erf:/traces/enc.gz
BUGS
This software should support encrypting based on the direction/interface flag.
IP addresses inside ARP's are not encrypted.
