After port scanning reveals open ports, you still need to know exactly which service and protocol is listening on each one. This Skill uses nerva (Praetorian's upgraded successor to fingerprintx) to fingerprint 120+ protocols across TCP, UDP, and SCTP, turning raw port lists into actionable service intelligence.
Ask the AI to fingerprint the services running on a target host and port list using nerva and output the results as JSON.

Run nerva against target host:port pairs with the -t flag, or pass a file of targets with -l. It fingerprints 120+ protocols and returns the identified service with metadata, optionally in JSON format via the --json flag.
Pipe the port scanner output directly into nerva. For naabu, run naabu -host <target> -silent | nerva --json. For masscan, extract open host:port pairs with grep and awk, then pipe them into nerva with -o to save JSON results.
Yes, nerva supports UDP probing with the -U flag, for example nerva -t 192.168.1.1:161 -U for SNMP. It also supports TCP and SCTP transport layers depending on the protocol being fingerprinted.
nerva is Praetorian's upgraded successor to fingerprintx. It expands coverage to 120+ protocols including industrial control systems and message queues, adds multi-transport support across TCP, UDP, and SCTP, and extracts richer service metadata.
Use -w to set timeout in milliseconds and -W to limit concurrency, for example nerva -t targets -w 2000 -W 50. For large target lists, apply rate limiting with -R, such as nerva -l targets.txt -R 100.
