Setup of the Comparison Tool

How to prepare data and your systems to use the comparison tool.

Requesting the “Comparison Tool”

To request the “Comparison Tool,” you must have an active trial.

Logfile Mode

For logfile mode, the tool requires a file containing a list of IPs to be checked. This list should be extracted from the log files of your production system(s). The logs should be at most two days old and as recent as possible for the best results. These can either be a simple de-duplicated list of IP addresses or a list containing a count (e.g., occurrences) and IP addresses, with the latter being preferred as it will provide a more accurate result.


Data Preparation

Here is an example of extracting a list of IPs using standard UNIX tools from a Postfix server. This can be modified to work with most logfile formats with some minor modifications.

$ grep -Poh '\d+\.\d+\.\d+\.\d+' /var/log/mail.log | sort  | uniq -c | sort -rn > ips_to_test

This will create a file called “ips_to_test” containing “<count> <ip>” where <count> is the number of times that IP address has been seen in the logs and will be sorted by the IPs with the largest number of occurrences first.
