In blue–green deployments, two servers are maintained: a "blue" server and a "green" server. At any given time, only one server is handling requests (e.g., being pointed to by the DNS ). For example, public requests may be routed to the blue server, making it the production server and the green server the staging server, which can only be ...
The command to create a local repo, git init, creates a branch named master. [61] [111] Often it is used as the integration branch for merging changes into. [112] Since the default upstream remote is named origin, [113] the default remote branch is origin/master. Some tools such as GitHub and GitLab create a default branch named main instead.
Rsync has numerous command line options and configuration files to specify alternative shells, options, commands, possibly with full path, and port numbers. Besides using remote shells, tunnelling can be used to have remote ports appear as local on the server where an rsync daemon runs.

The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
This command is often used to obtain the IP of an abusive user to more effectively perform a ban. It is unclear what, if any, privileges are required to execute this command on a server. This command is not formally defined by an RFC, but is in use by some IRC daemons. Support is indicated in a RPL_ISUPPORT reply (numeric 005) with the USERIP ...
HTTP/2 Server Push is an optional [1] feature of the HTTP/2 and HTTP/3 network protocols that allows servers to send resources to a client before the client requests them. Server Push is a performance technique aimed at reducing latency by sending resources to a client preemptively before it knows they will be needed. [ 2 ]
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.
