Using SSH keys has become the default method for accessing remote directories here at Customer Paradigm so making sure that everyone can access them can be a bit of trouble.  Typically the keys generated are OpenSSH keys making them available to all users.  Sometimes they are generated as Putty keys.  I will describe how a Mac user here at Customer Paradigm uses each type of key.


Option 1: OpenSSH key

Download the key into a given directory.

Open the terminal and enter the following at the command line:

cd /directory/containing/key (ex. cd /Users/ikua/ddo_keys/)

Make sure key is there by using the following at the command line:


Change the permissions on the file by entering the following:

chmod 500 <name_of_key>

Now SSH into the server.

ssh -i <name_of_key> <user_name>@<server_ip>


Option 2: Use an existing Putty Key

Install MacPorts if you have not already.


Open a terminal and enter the following to install Putty:

sudo port install putty

Putty will be installed along with Puttygen. Now you can use Putty for your SSH needs on a Mac.


You can also use Puttygen to convert the PPK to OpenSSH.

Here is an example of what to enter in the command line:

puttygen <key_name>.ppk -O private-openssh -o <key_name>


Good luck and share your Mac SSH experiences and any tips you might have with us in your comments.
