dpl4hydra v0.9.9 (c) 2012 by Roland Kessler (@rokessler)

Syntax: `basename $0` [help] | [refresh] | [BRAND] | [all]

This script depends on a local (d)efault (p)assword (l)ist called
${FULLFILE}. If it is not available, regenerate it with
'`basename $0` refresh'. Source of the default password list is
$SITE

Options:
  help        Help: Show this message
  refresh     Refresh list: Download the full (d)efault (p)assword (l)ist
              and generate a new local ${FULLFILE} file. Takes time!
  BRAND       Generates a (d)efault (p)assword (l)ist from the local file
              ${FULLFILE}, limiting the output to BRAND systems, using
              the format username:password (as required by THC hydra).
              The output file is called dpl4hydra_BRAND.lst.
  all         Dump list of all systems credentials into dpl4hydra_all.lst.

Example:
# `basename $0` linksys
File dpl4hydra_linksys.lst was created with 20 entries.
# hydra -C ./dpl4hydra_linksys.lst -t 1 192.168.1.1 http-get /index.asp
