It follows a three-tier model with dozens of NUT device driver daemons that communicate with power-related hardware devices over selected media using vendor-specific protocols, the NUT server upsd which represents the drivers on the network (defaulting to IANA registered port 3493/tcp [1]) using the standardized NUT protocol, and NUT clients ...
A nutdriver or nut driver is a hand tool for tightening or loosening nuts and bolts. It essentially consists of a socket attached to a shaft and cylindrical handle and is similar in appearance and use to a screwdriver. [1] They generally have a hollow shaft to accommodate a shank onto which a nut is threaded.
Promiscuous mode is often used to diagnose network connectivity issues. There are programs that make use of this feature to show the user all the data being transferred over the network. Some protocols like FTP and Telnet transfer data and passwords in clear text, without encryption, and network scanners can see this data.
HackThisSite is known for its IRC network, where many users converse on a plethora of topics ranging from current events to technical issues with programming and Unix-based operating systems. Mostly, the HackThisSite IRC network serves as a social gathering of like-minded people to discuss anything.
IP fragmentation attacks are a kind of computer security attack based on how the Internet Protocol (IP) requires data to be transmitted and processed. Specifically, it invokes IP fragmentation, a process used to partition messages (the service data unit (SDU); typically a packet) from one layer of a network into multiple smaller payloads that can fit within the lower layer's protocol data unit ...
A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
The original version of netcat was a Unix program. The last version (1.10) was released in March 1996. [4]There are several implementations on POSIX systems, including rewrites from scratch like GNU netcat [5] or OpenBSD netcat, [6] the latter of which supports IPv6 and TLS.
Linux kernel: network device drivers and network stack. Utility programs are not depicted, they communicate through the SCI with the different components of the kernel. To connect computers with each other, various communications protocols have been developed, e.g. IEEE 802.3 (Ethernet), IEEE 802.11 ("wireless"), IEEE 802.15.1 (Bluetooth ...
