scamper
Internet measurement tool for traceroute and probing
TLDR
SYNOPSIS
scamper [-c command] [-i target] [-f file] [-o output] [options]
DESCRIPTION
scamper is a network measurement tool designed for large-scale Internet research. It supports multiple probing techniques including traceroute, ping, DNS lookups, alias resolution, and load-balanced path detection, running them efficiently against many targets with configurable parallelism and rate limiting.
Results are stored in the warts binary format, which captures rich metadata including precise timing, ICMP responses, and measurement parameters. Companion tools (scwarts2json, scwarts2csv, etc.) convert warts data into common formats for analysis. Rate limiting controls prevent overwhelming target networks while maintaining measurement throughput.
