  • Partition - Partitioning a Hard Drive
    Partition - Partitioning a hard drive What is a partition? The partitioning of a hard drive occurs after the drive has been physically formatted but before it is logically formatted. It involves creating areas on the disk where data will not be mixed. It can be used, for example, to install differentoperating systems that do not use the same file system. There will therefore be at least as many partitions as there are operating systems using different file systems. If you are using just one operating system, a single partition the full size of the disk is sufficient, unless you want create several partitions so as to have, for example, several drives on which data are kept separate. There are three types of partitions: primary partitions, extended partitions andlogical drives. A disk may contain up to four primary partitions (only one of which can be active), or three primary partitions and one extended partition. In the extended partition, the user can create logical drives (i.e. "simulate" several smaller-sized hard drives). Let's look at an example where the disk contains one primary partition and one extended partition made up of three logical drives (later we will look at multiple primary partitions): For DOS systems (DOS, Windows 9x), only the primary partition is bootable, and is therefore the only one on which the operating system can be started. Partitioning is the process of writing the sectors that will make up the partition table (which contains information on the partition: size in sectors, position with respect to the primary partition, types of partitions present, operating systems installed,...).

  • List of NMAP Scripts Use with the Nmap –Script Option
    List of NMAP Scripts Use with the nmap –script option Retrieves information from a listening acarsd daemon. Acarsd decodes ACARS (Aircraft Communication Addressing and Reporting System) data in real time. The information retrieved acarsd-info by this script includes the daemon version, API version, administrator e-mail address and listening frequency. Shows extra information about IPv6 addresses, such as address-info embedded MAC or IPv4 addresses when available. Performs password guessing against Apple Filing Protocol afp-brute (AFP). Attempts to get useful information about files from AFP afp-ls volumes. The output is intended to resemble the output of ls. Detects the Mac OS X AFP directory traversal vulnerability, afp-path-vuln CVE-2010-0533. Shows AFP server information. This information includes the server's hostname, IPv4 and IPv6 addresses, and hardware type afp-serverinfo (for example Macmini or MacBookPro). Shows AFP shares and ACLs. afp-showmount Retrieves the authentication scheme and realm of an AJP service ajp-auth (Apache JServ Protocol) that requires authentication. Performs brute force passwords auditing against the Apache JServ protocol. The Apache JServ Protocol is commonly used by ajp-brute web servers to communicate with back-end Java application server containers. Performs a HEAD or GET request against either the root directory or any optional directory of an Apache JServ Protocol ajp-headers server and returns the server response headers. Discovers which options are supported by the AJP (Apache JServ Protocol) server by sending an OPTIONS request and lists ajp-methods potentially risky methods. ajp-request Requests a URI over the Apache JServ Protocol and displays the result (or stores it in a file).
