HOW TO SET UP SSH ON MAC CODE
Now try logging into the machine, with: "ssh check to make sure that only the key(s) you wanted were the ssh keys are set up, we can connect to .uk and we will be authenticated using the ssh key and password, so that entering the one time code is not longer needed.Ī successful login with password and ssh keys looks like this: ssh -X The code received by email (timestamp 19:04:59): Unauthorised access is a criminal offence under United * * Use of this system is restricted to registered members of The University *
HOW TO SET UP SSH ON MAC INSTALL
usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed - if you are prompted now it is to install the new keys usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed ssh-copy-id authenticity of host '.uk (134.225.114.116)' can't be established.ĮCDSA key fingerprint is SHA256:ZeDQ/ns8OcD4ZpWw0R+1NlZ2GEHup08+YdSG+TrOyRY.Īre you sure you want to continue connecting (yes/no/)? yes You can see the procedure in the screenshot below. As we need to login to arc-ssh in order to transfer the key, we need to use a one time code as the second authentication factor (in addition to the UoR password, which is always required). This is achieved with the command ‘ssh-copy-id’. The public key, id_rsa.pub, should be copied to the remote server. The private key, id_rsa, should stay on your machine and it should be kept secret. *o=X+o we see in the output above, a pair of keys was created. SHA256:Tc0MZiEuZS/9i2T6w/G3taoy5c+DeufkzHEEUm23C/0 key's randomart image is: Your public key has been saved in /home/janedoe/.ssh/id_rsa.pub Your identification has been saved in /home/janedoe/.ssh/id_rsa ssh-keygenĮnter file in which to save the key (/home/janedoe/.ssh/id_rsa):Įnter passphrase (empty for no passphrase): In this case, we will also not protect this ssh key with a passphrase because here the ssh key is just one of the two authentication steps and we will need our UoR password anyway. We will use the default file name id_rsa. Let us create the ssh keys with the ‘ssh-keygen’ command as seen below. Here, we will not do it by hand, but we will use the convenient ssh-copy-id command which will also automatically create missing files or directories and correct access permissions if necessary. The public key should be appended to the file ~/.ssh/authorized_keys in our UoR Unix home directory. You can skip this step if you already have a public and private key pair in your ~/.ssh/ directory. Setting up ssh keys – this replaces inconvenient one time codes and it is recommended for all arc-ssh usersįirst, we create an ssh key pair on the home machine. we assume that you are working from home, you want to use ssh keys and your openssh version is fairly recent.ġ.
HOW TO SET UP SSH ON MAC SERIES
This document builds on what is already described in the general instructions for arc-ssh, but the goal is to present it as a consistent series of steps, suitable for this particular use case, e.g.
The commands and the configuration options should be treated just as examples, they might need to be modified to work on your own machine. We also mention ssh multiplexing and other tips and trick to automate everyday tasks, which is aimed at more experienced users.
HOW TO SET UP SSH ON MAC HOW TO
Here we discuss how to set up ssh key authentication, which is recommended for all users. It might be useful to read the MobaXterm article for some extra background explanations. There is also the sibling article arc-ssh with MobaXterm – step by step guide. Connection caching is discussed later in this article can be also useful in the case of scripted data transfer from off-campus systems. In this article we show how to set up a home Unix machine to connect to campus services via arc-ssh.
