You will need a public key to log into cloud servers you provision. When you generate your keys, you will use ssh-keygen to store the keys in a safe location so you can bypass the login prompt when connecting to your server. To generate SSH keys in Mac OS X, follow these steps: Enter the following command in the Terminal window. Ssh-keygen -t rsa. SSH is a secure network protocol. With an SSH connection, you can access your Raspberry Pi remotely from another device – whether that be a Mac, PC, or smartphone. Remote access to your Raspberry Pi is especially handy if your Pi is acting as a web server – or as any kind of server, for that matter. How to SSH into the Raspberry Pi. Mac OS X and Linux both comewith an SSH client built in.To get to it, open up a terminal window.There, you'll need to type'ssh' and at minimum, the server name.If you don't specify a user nameSSH will assume you want to usethe same user name that you're usingon your local computer.You can specify a user with '-l'that stands for log-infollowed by the user name. I'm using Mac OS X 10.6.4, along with a couple of other people on the same network. I have a firewall set up on my computer While I am able to connect to most people remotely, using the command (in terminal) ssh username@IP address (I get the IP address by pinging the computer name) There are a couple of people where I come across the message of: 'Port 22: Connection refused' (or something.
Like many have answered, Cyberduck is a great free and open source tool for this. – Oskar Sep 22 '11 at 12:57 Since you're on Snow Leopard, have a look at MacFusion - you can just mount an ssh/sftp connection like a network volume, simple.
In the past, we’ve showed you how to set up an FTP server on a Raspberry Pi. Now we’re going to show you how to do something very similar: use SSH (Secure Shell) to access your Raspberry Pi from other devices.
SSH is a secure network protocol. With an SSH connection, you can access your Raspberry Pi remotely from another device – whether that be a Mac, PC, or smartphone. Remote access to your Raspberry Pi is especially handy if your Pi is acting as a web server – or as any kind of server, for that matter.
How to SSH into the Raspberry Pi
Step 1: Enable SSH
As you might remember from our FTP server how-to, the first thing we need to do is make sure that SSH is enabled on your Raspberry Pi. This can be done two ways: using the GUI or using Terminal. Which method you use is entirely up to you! We’ll cover both below.
Using the GUI
Head over to Preferences > Raspberry Pi Configuration and click on “Interfaces.” While there, select “SSH: Enabled.”
Using Terminal
Open Terminal and enter this command:
Then head over to Advanced Options and select SSH. You are asked whether you would like the SSH server to be enabled. Select “Yes.”
Now the SSH server is enabled and you can exit the config.
Step 2: Determine your IP address
In order to connect to your Raspberry Pi, you have to know your Raspberry Pi’s IP address. If you’re going to connect to your Raspberry Pi from inside your home network, open Terminal and enter this command:
If you want to connect to your Pi from outside of your home network, you will have to set up port forwarding and determine your public IP address instead.
Obtaining your public IP address is very easy. Just head to a search engine – like DuckDuckGo, the default search engine on Raspbian – and type “what is my IP address.” Hit search and your search engine of choice should provide your answer. You IP address will be in this format: ###.###.###.### – where each # is a digit, of course.
Whether you want to connect on your home network (with a private IP address) or from outside your network (with the public IP address), you’re going to need to remember the digits, so write your IP address down!
Step 3: SSH into your Raspberry Pi
Windows
To connect to your Raspberry Pi with SSH, you’ll need a popular program called PuTTY. In the words of its creator, PuTTY is “a free implementation of SSH and Telnet for Windows and Unix platforms.” You can download PuTTY here. Just choose putty.exe’s 32 bit or 64 bit version, depending on which version of Windows you have.
Once you’ve finished downloading, go ahead and launch putty.exe. You’ll be greeted with a screen like this:
See the “Host Name (or IP address)” field? That’s where you’ll want to enter your Raspberry Pi’s IP address as determined in the previous step.
Make sure that the “Port” field has a value of “22.”
Now, click “Open.”
You’ll get a security alert next – go ahead and hit “Yes” on that.
Finally, log in to your Raspberry Pi. If you haven’t changed the defaults, your username will be “pi” and your password will be “raspberry”.
You are now connected to your Pi and can control the device remotely with Linux commands. If you don’t know much about Linux commands, here’s a comprehensive list.
Mac OS X
Establishing an SSH connection to the Raspberry Pi on Mac OS X is very straightforward, since the operating systems comes with Terminal installed. You just have to open Terminal and enter this command:
(###.###.###.### here represents your IP address, of course.)
Mac Terminal Ssh
After issuing the command, you’ll be prompted with a security alert. Type “yes” to continue.
Log in to your Raspberry Pi. If you’ve left the defaults unchanged, the username will be “pi” and the password will be “raspberry”.
You are now connected to your Pi and can control the device remotely with Linux commands. As mentioned in the Windows section, you can find a comprehensive list of Linux commands here.
Troubleshooting
If you can’t establish an SSH connection to your Raspberry Pi, here are a couple of things you can do:
- Make sure that you have enabled SSH on your Raspberry Pi
- Make sure that you’re using the correct IP address
- Make sure that you have the correct credentials
- If you’re connecting from outside of your home network, make sure that you have set up port forwarding
If you still have problems in connecting, please post a comment below.
Obtain SSH credentials
Obtain SSH credentials from the Bitnami Launchpad
The Bitnami Launchpad for Microsoft Azure automatically injects an auto-generated public SSH key for the bitnami user and allows the user to download the private SSH key. To do so, follow these steps:
- Browse to the Bitnami Launchpad for Microsoft Azure and sign in if required using your Bitnami account.
- Select the “Virtual Machines” menu item.
- Select your cloud server from the resulting list.
- Download the SSH key for your server (.pem for Linux and Mac OS X, .ppk for Windows). Note the server IP address on the same page.
Obtain SSH credentials from the Azure Marketplace
If you are using the Microsoft Azure Marketplace, you will have been presented with a choice of using either an SSH password or an SSH key pair at the time of deploying the server as shown below:
Option 1: SSH key pair
If you have copied and pasted your SSH key file during the deployment of the server, you can retrieve your key in the “Resource Group -> Deployments” section. Click on your deployment, you will see a summary with the related information:
Option 2: SSH password
The SSH password that you have entered during the server deployment is the same that you will use to access your server through an SSH client and to access the server through an SSH tunnel.
Connect with an SSH client
TIP: Refer to these instructions to learn how to obtain your SSH credentials.
NOTE: If you specified a custom username for SSH access when deploying your server, replace bitnami in the examples below with the correct username.
Connect with an SSH client on Windows using an SSH key
In order to access your server via SSH tunnel you need an SSH client. In the instructions below we have selected PuTTY, a free SSH client for Windows and UNIX platforms. To access the server via SSH tunnel using PuTTY on a specific port using an SSH tunnel, you need to have it configured in order to allow connections to your server.
Step 1: Obtain PuTTY
- Download the PuTTY ZIP archive from its website.
- Extract the contents to a folder on your desktop.
- Double-click the putty.exe file to bring up the PuTTY configuration window.
Step 2: Convert your PEM private key to PPK format (optional)
If your private key is in .pem format, it is necessary to convert it to PuTTY’s own .ppk format before you can use it with PuTTY. If your private key is already in .ppk format, you may skip this step.
Follow the steps below to convert your .pem private key to .ppk format:
- Launch the PuTTY Key Generator by double-clicking the puttygen.exe file in the PuTTY installation directory.
Click the “Load” button and select the private key file in .pem format.
Once the private key has been imported, click the “Save private key” button to convert and save the key in PuTTY’s .ppk key file format.
Step 3: Configure PuTTY
- Double-click the putty.exe file to bring up the PuTTY configuration window.
In the PuTTY configuration window, enter the host name or public IP address of your server into the “Host Name (or IP address)” field, as well as into the “Saved Sessions” field. Then, click “Save” to save the new session so you can reuse it later.
Obtain your SSH credentials in order to allow the authentication against the server. Refer to the FAQ to learn how to obtain your SSH credentials for your client.
In the “Connection -> SSH -> Auth” section, browse to the private key file (.ppk) you’ve previously obtained in the step above.
In the “Connection -> Data” section, enter the username bitnami into the “Auto-login username” field, under the “Login details” section.
In the “Session” section, click on the “Save” button to save the current configuration.
Select the session you want to start (in case that you have saved more than one session) and click the “Open” button to open an SSH session to the server.
PuTTY will first ask you to confirm the server’s host key and add it to the cache. Go ahead and click “Yes” to this request (learn more).
You should now be logged in to your server. Here is an example of what you’ll see:
TIP: In case of difficulties using PuTTY, refer to the official documentation for troubleshooting advice and resolution for common error messages.

Forward your key using SSH Agent
With key forwarding, you can connect to a host using an SSH key and then make the key available for subsequent SSH connections from that host. Key forwarding lets you connect to a host (host A) with your SSH key, and then connect to another host (host B) from host A using the same key.
Forward your key using SSH Agent on Windows
Ssh Server For Mac Os X 10.10
To forward your SSH key using PuTTY, you must first have SSH access to your server. Please check the SSH instructions for Windows section for more information on this.
Once you have your SSH client correctly configured, enable SSH Agent forwarding. To do so, follow these steps:
In the “Connection -> SSH -> Auth” section, activate the “Allow agent forwarding” checkbox.
In the “Session” section, save your changes by clicking the “Save” button.
Click the “Open” button to open an SSH session to the server. The SSH session will now forward your key for subsequent SSH sessions starting from the same server. You can check this by running the following:
