Exam XK0-005 topic 1 question 118 discussion

The file that can be used to set a different port value for a specific remote host in SSH is option C, ~/.ssh/config. The ~/.ssh/config file is a per-user configuration file that SSH reads before connecting to a remote host. It allows users to set various SSH options for specific hosts, eliminating the need to pass these options on the command line every time.

Only the server side can change the port value in '/etc/ssh/sshd_config'.

Ugh... these questions! "Which of the following files can be used to set a different port value for that host?" Only the server side can change the port value in '/etc/ssh/sshd_config'. By specifying the port on the client side in '~/.ssh/config', one need not specify the port every time from the command line, but this does not "set a different port value for that host." SMH. I surely hope the test is not like this.

The correct answer is C. ~/.ssh/config.

Answer is C For an individual user's connections to a remote system, create and/or modify the client side's ~/.ssh/config file. For every user's connection to a remote system, create and modify the client side's /etc/ssh/ssh_config file.
