Where are the OpenSSH client configurations typically located?

The OpenSSH client configurations are typically found in the file located at /etc/ssh/ssh_config. This file is designed for configuring user-level settings for SSH clients on a system. It allows users to set default parameters for their SSH connections, such as the SSH protocol version, user authentication methods, and preferred cipher algorithms.

The main purpose of the ssh_config file is to provide settings that apply when a user initiates an SSH session to connect to a remote server, making it a critical component of the SSH client's functioning. Unlike the sshd_config file, which controls the SSH server's configuration, ssh_config is focused solely on client-based configurations.

In this context, other choices do not serve as the primary location for OpenSSH client configurations; for instance, /etc/ssh/sshd_config is dedicated to the SSH daemon's settings and governs the server's behavior rather than client configurations. Other paths, such as /usr/local/etc/ssh and /var/ssh/config, may not be standard or could be used in specific setups but are not the conventional locations for SSH client configurations.
