2. [`SSHFinger`][ssh-finger] - Fingerprints target machines over SSH (port 22) and extracts the computer version and SSH banner.
3. [`PingScanner`][ping-scanner] - Fingerprints target machine's TTL to differentiate between Linux and Windows hosts.
4. [`HTTPFinger`][http-finger] - Detects HTTP/HTTPS services, using the ports listed in `HTTP_PORTS` in the configuration, will return the server type and if it supports SSL.
5. [`MySQLFinger`][mysql-finger] - Fingerprints MySQL (port 3306) and will extract MySQL banner info - version, major/minor/build and capabilities.
6. [`ElasticFinger`][elastic-finger] - Fingerprints ElasticSearch (port 9200) will extract the cluster name, node name and node version.
