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 | --key- file=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 pre- fix. -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". Com- pression level can range from 0 (no compression) through to 9. Higher compression levels require more CPU to compress data. De- faults 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.
