Even in those countries where the 12-hour clock is predominant, there are frequently contexts (such as science, medicine, the military or transport) in which the 24-hour clock is preferred. In most countries, however, the 24-hour clock is the standard system used, especially in writing. Some nations in Europe and Latin America use a combination ...
An ephemeral port is a communications endpoint of a transport layer protocol of the Internet protocol suite that is used for only a short period of time for the duration of a communication session. Such short-lived ports are allocated automatically within a predefined range of port numbers by the IP stack software of a computer operating system.
tc relates to the Linux kernel packet scheduler as iptables to netfilter. Both are user-space CLI programs that are used to configure their respective Linux kernel subsystem. tc (traffic control) is the user-space system administration utility program used to configure the Linux kernel packet scheduler.
In computer networking, localhost is a hostname that refers to the current computer used to access it. The name localhost is reserved for loopback purposes. [1] It is used to access the network services that are running on the host via the loopback network interface. Using the loopback interface bypasses any local network interface hardware.
The name localhost is a commonly defined hostname for the loopback interface in most TCP/IP systems, resolving to the IP addresses 127.0.0.1 in IPv4 and ::1 for IPv6.As a top-level domain, the name has traditionally been defined statically in host DNS implementations with address records (A and AAAA) pointing to the same loopback addresses.
The command is also available in the Motorola VERSAdos, [5] Intel iRMX 86, [6] PC-MOS, [7] SpartaDOS X, [8] ReactOS, [9] SymbOS, and DexOS operating systems as well as in the EFI shell. [10] On MS-DOS, the command is available in versions 1 and later. [11] In Unix, the date command displays and sets both the time and date, in a similar manner.
The port mapper (rpc.portmap or just portmap, or rpcbind) is an Open Network Computing Remote Procedure Call (ONC RPC) service that runs on network nodes that provide other ONC RPC services. Version 2 of the port mapper protocol maps ONC RPC program number/version number pairs to the network port number for that version of that program.
On various routers, this TCP or UDP port 7 for the Echo Protocol for relaying ICMP datagrams (or port 9 for the Discard Protocol) is also configured by default as a proxy to relay Wake-on-LAN (WOL) magic packets from the Internet to hosts on the local network in order to wake them up remotely (these hosts must also have their network adapter ...
