How can I change the SSH key use from /etc/ssh/ to ~/.ssh/id_rsa
At the moment when I run ssh -T git@github.com -A -p 22
it finds the key in /etc/ssh/ssh_host_ed25519_key
I also did assign another port on sshd_config and ssh_config from 22 to something else.
In systemctl status the new Port is confirmed after restart sshd but ssh is still running on Port 22 at the moment.
I’m thankful for any help
my ssh_config is:
# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/local/sbin:/usr/local/bin:/usr/bin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.
