Test, validate and match regular expressions
Parses SSH log records by capturing five fields: an IPv4-style address, free-form message text, a MAC-like identifier in XX-XX-XX-XX-XX-XX:XX format, a string beginning with 'AHM', and a trailing 1-3 digit number. Intended for extracting structured data from SSH daemon or router/network device logs line by line. Note that the dots in the IP capture group are unescaped, so they technically match any character.
