Configuring OpenSSH



SSH server (sshd)




/etc/ssh/sshd_config 


Directives:

- AllowUsers

- DenyUsers

- HostKey

- ListenAddress

- PermitRootLogin

- Port

- Protocol







SSH client 





/etc/ssh/ssh_config





file.







The





/etc/ ssh/ssh_config 






file is used to specify default parameters for all users running ssh on the system.





A user can override these defaults using the





~/.ssh/ssh_config 






file in his or her home directory.






The precedence for ssh client configuration settings are as follows:





1. Any command-line options included with the ssh command at the shell prompt



2. Settings in the ~/.ssh/ssh_config file



3. Settings in the /etc/ssh/ssh_config file










Connect




ssh –l user_name ip_address





Don’t forget the –l parameter. If you don’t, the SSH client will
attempt to authenticate you to the remote system using the same
credentials you used to authenticate to the local system.
