Su desarrollo ha sido intensivo, ya que nace en el Google Summer Of Code del año pasado. Pese a que actualmente es versión 0.01ALPHA, no hemos querido dejar escapar la oportunidad para ver qué pinta tiene.
Ncrack 0.01ALPHA ( http://ncrack.org )
Usage: ncrack [Options] {target specification}
TARGET SPECIFICATION:
Can pass hostnames, IP addresses, networks, etc.
Ex: scanme.nmap.org, microsoft.com/24, 192.168.0.1; 10.0.0-255.1-254
-iL <inputfilename>: Input from list of hosts/networks
--exclude <host1[,host2][,host3],...>: Exclude hosts/networks
--excludefile <exclude_file>: Exclude list from file
SERVICE SPECIFICATION:
Can pass target specific services in <service>://target (standard) notation or
using -p which will be applied to all hosts in non-standard notation.
Service arguments can be specified to be host-specific, type of service-specific
(-m) or global (-g). Ex: ssh://10.0.0.10,at=10,cl=30 -m ssh:at=50 -g cd=3000
Ex2: ncrack -p ssh,ftp:3500,25 10.0.0.10 scanme.nmap.org google.com:80,ssl
-p <service-list>: services will be applied to all non-standard notation hosts
-m <service>:<options>: options will be applied to all services of this type
-g <options>: options will be applied to every service globally
Misc options:
ssl: enable SSL over this service
path <name>: used in modules like HTTP ('=' needs escaping if used)
TIMING AND PERFORMANCE:
Options which take <time> are in milliseconds, unless you append 's'
(seconds), 'm' (minutes), or 'h' (hours) to the value (e.g. 30m).
Service-specific options:
cl (min connection limit): minimum number of concurrent parallel connections
CL (max connection limit): maximum number of concurrent parallel connections
at (authentication tries): authentication attempts per connection
cd (connection delay): delay <time> between each connection initiation
cr (connection retries): caps number of service connection attempts
to (time-out): maximum cracking <time> for service, regardless of success so far
-T<0-5>: Set timing template (higher is faster)
--connection-limit <number>: threshold for total concurrent connections
AUTHENTICATION:
-U <filename>: username file
-P <filename>: password file
--passwords-first: Iterate password list for each username. Default is opposite.
OUTPUT:
-oN/-oX <file>: Output scan in normal and XML format, respectively, to the given filename.
-oA <basename>: Output in the two major formats at once
-v: Increase verbosity level (use twice or more for greater effect)
-d[level]: Set or increase debugging level (Up to 10 is meaningful)
--nsock-trace <level>: Set nsock trace level (Valid range: 0 - 10)
--log-errors: Log errors/warnings to the normal-format output file
--append-output: Append to rather than clobber specified output files
MISC:
-6: Enable IPv6 cracking
-sL or --list: only list hosts and services
--datadir <dirname>: Specify custom Ncrack data file location
-V: Print version number
-h: Print this help summary page.
[aramosf@sbd ncrack]$ ./ncrack ssh://192.168.0.3:444 -U usuarios -P pass
Warning: File ./usuarios exists, but Ncrack is using usuarios for security and consistency reasons. Set NCRACKDIR=. to give priority to files in your local directory (may affect the other data files too).

Aw, this was a really quality post. In theory I’d like to write like this too – taking time and real effort to make a good article… but what can I say… I procrastinate alot and never seem to get something done.
