snort

Snort is a libpcap-based packet sniffer/logger which can be used as a lightweight network intrusion detection system. It features rules-based logging and can perform content searching/matching in addition to detecting a variety of other attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, and much more. Snort has a real-time alerting capability, with alerts being sent to syslog, a separate “alert” file, or even to a Windows computer via Samba.

This package provides the plain-vanilla version of Snort.

Snort has several options to get more help:

-? list command line options (same as --help)
--help this overview of help
--help-commands [<module prefix>] output matching commands
--help-config [<module prefix>] output matching config options
--help-counts [<module prefix>] output matching peg counts
--help-limits print the int upper bounds denoted by max*
--help-module <module> output description of given module
--help-modules list all available modules with brief help
--help-modules-json dump description of all available modules in JSON format
--help-plugins list all available plugins with brief help
--help-options [<option prefix>] output matching command line options
--help-signals dump available control signals
--list-buffers output available inspection buffers
--list-builtin [<module prefix>] output matching builtin rules
--list-gids [<module prefix>] output matching generators
--list-modules [<module type>] list all known modules
--list-plugins list all known modules
--show-plugins list module and plugin versions

--help* and --list* options preempt other processing so should be last on the
command line since any following options are ignored.  To ensure options like
--markup and --plugin-path take effect, place them ahead of the help or list
options.

Options that filter output based on a matching prefix, such as --help-config
won't output anything if there is no match.  If no prefix is given, everything
matches.

u2boat

Unified2 Binary Output & Alert Tool

U2BOAT(1)                   General Commands Manual                   U2BOAT(1)

NAME
       u2boat - Unified2 Binary Output & Alert Tool

SYNOPSIS
       u2boat [-t type] <infile> <outfile>

DESCRIPTION
       This manual page documents briefly the u2boat command.  This manual page
       was  written  for  the  Debian distribution because the original program
       does not have a manual page.

       u2boat is a utility that converts Snort's Unified2 logs  to  other  for-
       mats.  It was introduced in Snort due to the lack of support for formats
       that were present in the Snort 2.8.x releases.  Unified2 logs  to  other
       formats.

OPTIONS
       -t type
              Type specifies the type of output that the program should create.
              The only current valid option is 'pcap'

u2spewfoo

Tool for dumping the contents of unified2 files to stdout

root@kali:~# man u2spewfoo
U2SPEWFOO(1)                General Commands Manual                U2SPEWFOO(1)

NAME
       u2spewfoo -  tool for dumping the contents of unified2 files to stdout

SYNOPSIS
       u2boat <infile>

DESCRIPTION
       This  manual  page documents briefly the u2spewfoo command.  This manual
       page was written for the Debian distribution because the  original  pro-
       gram does not have a manual page.

       u2spewfoo is a lightweight tool for dumping the contents of Snort's Uni-
       fied2 log files to stdout. In order to use it Snort first has to be con-
       figured to use this format in its configuration file.

       The  tool  will take the log file and dump the information on the events
       in Standard output. This information includes the event and relevant in-
       formation about it (such as IP addresses and ports, the time  the  event
       was  detected,  etc.) as well as the packet that triggered the event (if
       Snort has been configured to store  a  packet  capture  associated  with
       events).

EXAMPLES
       To  use  it  run  it  against  a unified2 log file by running: u2spewfoo
       snort.log

       The following is a sample output of this tool:
