network jack

network jack is intended as an internet troubleshooting / information gathering tool providing a web interface to several common command line tools, including ping, traceroute, dig, and whois, as well as a subnet mask calculator and a DNS block list (aka blackhole) lookup.

Current Modules

    - Ping a host on the internet (currently only IPv4)
  • Tracer
    - Traceroute to a host on the internet from the web server (currently only IPv4)
  • Digger
    - Do a DNS Dig of a hostname or IP address (for reverse lookups)
  • Drooler
    - block list lookup (aka RBL query, blackhole lookup)
  • Whoser

  • Netter
    - Mask / CIDR calculator

  • It is intended to be easy to add new modules
  • Seperates html code into it's own file so can be customized without modifying the program files

Nothing really besides what's included as part of the download.
