It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, etc.  Additional details can be found at  Below are some screen captures from Ubuntu version 10.04.  Scapy was not present by default, so it needed to be installed.


The command must be executed with root credentials.  Simply enter scapy, and the command prompt should appear.


The command ls() will display all of the various modules available.


To view options for a specific module such as TCP, enter the command ls(TCP).


Variables can be used to specify different values than the defaults.  The command ls() can be used to verify the value of the variable.


The commands below configure the destination port, source port, and payload variables.


The command send(i/t/p) will send the packet to the destination address with the variables, which is the loopback in this example.  The send command is at Layer 3; sendp is at Layer 2.


The tcpdump command can be used to verify the packet was sent.


Multiple ports can be used, as well as a range

Tcpdump Information

Tcpdump is a command-line packet capture tool normally found within Unix/Linux operating systems.  A Windows port can be found  Below are some common command switches for tcpdump.

-D = list available interfaces

-i = listen on the selected interface

-r = read the input file specified

-n = do not perform DNS resolution

-c = give a count of the number of records to process

-x = display data in hexadecimal

-e = display the MAC/Ethernet address information

-vv = verbose output

-X = display the ASCII payload of records

-w = write the data to a file

-q = quiet or quick output (less data)

‘tcp’ ‘ip’ ‘udp’ ‘icmp’ = macro filters for protocols

‘port’ = port filter

‘src port’ ‘dst port’ = source port and destination port filters

‘src host’ ‘dst host’ = source host and destination host filters

Below is an example of displaying the the available interfaces on an Ubuntu operating system, and then capturing traffic on one interface.


The example below reads a file called TEST, disables DNS and port resolution, and only display TCP traffic.


The example below reads a file called TEST, disables DNS and port resolution, and only display traffic using the port 23.


The command below continues the example but uses a filter to only include ICMP traffic and only where the destination host had the IP address of


The example below uses a filter to include data with a source host of or a destination port value of 23.


The verbose option will return additional details concerning the packets.

Outlook Configuration Analyzer Tool

The Outlook Configuration Analyzer Tool (OCAT ) provides a quick and easy method to analyze your Microsoft Office Outlook profile for common configurations that may cause problems in Outlook.  The Outlook Configuration Analyzer Tool provides a detailed report of your current Outlook profile.  This report includes many parameters about your profile, and it highlights any known problems that are found in your profile.  For any problems that are listed in the report, you are provided a link to a Microsoft Knowledge Base (KB) article that describes a possible fix for the problem.


The Calendar Checking Tool for Outlook (CalCheck) is a command-line program that checks Microsoft Outlook Calendars for problems.  The tool opens an Outlook profile to access the Outlook Calendar.  It performs various checks, such as permissions, free/busy publishing, delegate configuration, and automatic booking.  Then each item in the calendar folder is checked for known problems that can cause unexpected behavior, such as meetings that appear to be missing.  As CalCheck goes through this process, it generates a report that can be used to help diagnose problem items or identify trends.
