1) From the Mac functioning as an SSH Server:įirst you’ll want to grab the IP of the Mac running the server, this let’s another user/client know where to connect to:
SSH clients are bundled with Mac OS X and Linux so there are no downloads necessary there, you can just open the Terminal and use the ‘ssh’ commands, but iOS users can use Prompt and Windows users can get PuTTY (its free). The great thing about this is you can now connect to the Mac from virtually any other operating system, all you need is an SSH client.

Warning: Permanently added 'localhost' (RSA) to the list of known hosts.Ĭonnecting to localhost isn’t too useful though, and this is called Remote Login for a reason, because it allows for secured connections to remote Macs through either the SSH command line interface, SFTP through any modern FTP/SFTP client, or with a direct file transfer by using the scp command from the terminal of other Macs or unix machines. The authenticity of host 'localhost (::1)' can't be established. The easiest way to do this is to visit Terminal app and type either ‘ssh localhost’ or ‘sftp localhost’, which, if all is running as intended, should return something like this: Now that the SSH server has been enabled, you can verify they have enabled if you’d like. Think of this as an extra security step, although SSH by default is quite secure as is due to the nature of the protocol. This brings up a list of Users & Groups on the Mac that you can select from. If you want to limit incoming SSH access to certain users, you can do so in the same preference panel by ticking “Only these users” and then manually adding them by clicking on the + icon.
