Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
The hosts file is one of several system facilities that assists in addressing network nodes in a computer network. It is a common part of an operating system's Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network.
File Explorer (Preview Panes) adds SVG, Markdown and PDF previews to File Explorer. [27] File Locksmith adds the ability to check which files are in use and by which processes.

Added a history section to provide background on hosts files origins and uses. On my to-do list for this article: o Fix the crappy formatting, spelling errors, etc o Fix all the technical ambiguity, remove OS prejudices, etc. o Move chunks of the article into a more appropriate article, such as "Hosts_File_Filtering" or something
If you are looking for a simple, general mechanism for the local specification of IP addresses for specific hostnames (server names), use the HOSTS file, not the LMHOSTS file. The file, if it exists, is read as the LMHOSTS setting file. A sample file (lmhosts.sam) is provided. It contains documentation for manually configuring the file.
On social networking sites like Facebook, users may be able to block users which prevents the user they have blocked from seeing things on their profile or contacting them. [9] Such blocking is often reciprocal, meaning the blocking user is also blocked from seeing the profile and activities of the blocked party. [ 10 ]
In computer networking, MAC address filtering is a network access control method whereby the MAC address assigned to each network interface controller is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the ...
using byte-range locks to arbitrate read and write access to regions within a single file [3] by Windows file systems disallowing executing files from being opened for write or delete access; Windows inherits the semantics of share-access controls from the MS-DOS system, where sharing was introduced in MS-DOS 3.3 . Thus, an application must ...
