title: UDP Scans

description: The data format is gzip-compressed CSV with one record per line. Each file starts with a list of fields, so any use of this data should either strip the field headers, or pass the appropriate option to the parser. The current fields are timestamp-ts, saddr, sport, daddr, dport, ipid, ttl, and data. The timestamp-ts field is Unix time at UTC. The saddr and sport are the IP address that was scanned and the source port that it replied on respectively. The daddr and dport fields are the IP address and source port of the Project Sonar scanner. The ipid and ttl fields refer to the IP ID and Time to Live values in the response packet. Finally, the data field contains the hex-encoded raw response from the probe.

The example below displays the header and first 9 records from the 2014-10-13 Portmap probe on UDP port 111:

$ curl -s https://scans.io/data/rapid7/sonar.udp/20141013-portmap-111.csv.gz | \

The table below lists all current and past UDP probes. We use DAP to handle the decoding and processing probe responses. Every probe below has a corresponding DAP decoder filter.
