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 ] 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 NUL charactors.
EXAMPLES
- traceanon --cryptopan="fish go moo, oh yes they do" \
- --encrypt-source \
--encrypt-dest \

BUGS
This software should support encrypting based on the direction/interface flag.
IP addresses inside ARP's are not encrypted.
