Sam SpadeSam Spade is a set of tools for network-query designed to hunt down spammers. Each tool displays it’s output in it’s own window, and everything is multi-threaded so you don’t need to wait for one query to complete before starting the next one. Some functions are threaded still further to allow lazy reverse DNS lookups (never do a traceroute -n again). The output from each query is hotlinked, so you can right click on an email address, IP address, hostname or internic tag to run another query on it

Below are the tools you can use:

ping, nslookup, whois, IP block whois, dig, traceroute, finger, SMTP VRFY, web browser, keep-alive, DNS zone transfer, SMTP relay check, Usenet cancel check, website download, website search, email header analysis, Email blacklist query, Abuse address query, S-Lang scripting, Time.
