I don't have a website I maintain right now so I thought I'd post this to the mailing list.
I have a need to scan a list of IP addresses and I wanted the scan order to be random. Nmap can do this. However, I also want the scan order to be consistent so I can do handy things like diff output logs for changes. The following program generates a list of IPs, randomizes their order, and outputs to a file. The program ends up being very small but expressive; I developed against Clojure 1.1. Because this was one of my first clojure programs, it took a long time to write and I'd like the thank everyone that answered my questions in IRC and the mailing list. For completeness' sake, you can use the list of IPs with e.g. the following nmap command: nmap -iL ips.txt -sP -oG scanned_results.txt http://gist.github.com/484747 - - - - ; Generate a list of random IPs to be fed into nmap so that nmap may scan ; aggressively but not swamp any given subnet within the 172.16.0.0/12 range. ; ; Licensed under the EPL (fwiw ;) (use '[clojure.contrib.seq-utils :only (shuffle)] '[clojure.contrib.duck-streams :only (write-lines)]) (write-lines "./ips.txt" (shuffle (for [octet1 [172] octet2 (range 16 33) octet3 (range 256) octet4 (range 256)] (str octet1 \. octet2 \. octet3 \. octet4)))) - - - - - Ryan (arkh) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
