See you again next time.You need to make sure that in both computers port 22 is open (firewalls anywhere?) and that there is a network route from A to B. If they don’t match, you would get something like: Permission denied (publickey,gssapi-keyex,gssapi-with-mic) Note: One of the common mistakes is selecting the wrong key pair when launching the instance, so make sure the private key you use during SSH login and the key pair you selected prior match. You have successfully connected to your Linux EC2 instance via SSH. bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory ~]$Īs soon as you see your ec2 instance’s ip address as the prompt, you can start celebrating. You should then get something like this: Warning: Permanently added ',54.88.51.10' (ECDSA) to the list of known hosts. Are you sure you want to continue connecting (yes/no)? yes ECDSA key fingerprint is SHA256:dDmWU5MGZhIxAVEajRTRLSQvQ1OIbVN圓Et1FInpKVg. The authenticity of host ' (54.88.51.10)' can't be established. myfirstkeypair.pem should then get something like the message below. nameofyourprivatekey.pem ipaddress or hostnameįor example (this is one line): ssh -i.
To SSH to your EC2 instance from your Mac, just go back to your terminal (or launch it again if you’ve closed it already), navigate into the directory that contains your private key file, and then enter: ssh -i. Once you’ve launched the instance, take note of its Public DNS hostname or Public IP address, as you’ll also be needing either one when you connect via SSH. I won’t go into the details of creating a Linux EC2 instance, as that should belong to a separate post, but once you launch such an instance, you need to select the key pair you created so that Amazon EC2 will know what private key file to expect when you connect via SSH. You can now start using your private key to authenticate to your Amazon EC2 Linux instance via SSH. Navigate to the directory that contains your private key file and then enter: chmod 400 nameofyourpravatekey.pem

Launch the Mac terminal from the Dock or launch Mission Control (F4 button) and then go to Other > Terminal. Keep that private key file in a safe place and remember where you kept it, as you’ll need it every time you connect to your Linux EC2 instance via SSH.īefore you can use that private key file, you’ll need to change its permissions. Give the key pair a name and then click the Create button.Īs soon as the key pair is created, its name will be displayed among the list of key pairs and the private key will be automatically downloaded by your browser. Scroll down the left sidebar until you reach the Network & Security section and then click the Key Pairs menu. Generate Keys in Amazon EC2Įxpand the All Services drop-down and then click EC2 under the Compute section. Although you can generate a public-private key pair using a third party tool and then import the public key on Amazon EC2, we are going to go through the usual route which is to generate keys from Amazon EC2 itself. SSH logins are typically done through public key authentication, which requires users to have their private key on hand. We’re using a Mac, so some of our screenshots are going to be taken from a Mac UI.

In this post, we’re going to show you how to connect to a Linux EC2 instance via SSH. having no graphical user interface (GUI), you need to access them through the command line.
Since many of these Linux instances are headless, i.e. For quite some time now, Linux and its derivatives or distros have been the most widely used platform in the cloud.
