The Public Key Support section of the External Login page explains why using ssh public keys is a bad idea. If that doesn't help, ask Informatics Computing Support for help.
If this happens to you, just wait a while then try again. If you type it wrong several times you will be temporarily locked out. rm /.ssh/idrsa The keys filenames may be different - see the FILES section of. To remove a public key which you may previously have generated on your Mac, open Terminal once again and type.
If you type the wrong password your login will fail. The Public Key Support section of the External Login page explains why using ssh public keys is a bad idea. If you aren't using it, you will be prompted for your DICE password at this point. Ssh you are using Kerberos and GSSAPI, you will now be logged in to an Informatics ssh server. Make the on-prem MDM server the default one. Connect Apple School Manager to the new on-prem MDM server and setup all certificates etc. Replace servername with the name of the server to connect to.įor example, if your username was s1234567 and you wanted to connect to the Informatics ssh server for students, you would type this in the Terminal window: The one thing I could think of is this: - Make sure all (or as many as possible) computers are in Apple School Manager.
Replace username with your DICE username - for example s1234567. replacing username and servername with the correct values.
Once you have a Terminal window running, this is how to use ssh: ssh servername You can find this in the Utilities folder which is on the Finder's Go menu. To use ssh first start the Terminal application. Once you have configured ssh as shown on that page, you will be able to ssh to School servers without being prompted for your DICE username and password each time you connect. (But note that the GSSAPIRenewalForcesRekey option is not supported.) Those instructions are for Linux, but ssh on the Mac should be configured similarly. To use this you will need to set up Kerberos on your Mac.Īfter that, read the instructions for Using GSSAPI (Kerberos) authentication. The most secure way to authenticate with the Informatics SSH service is to use GSSAPI (Kerberos). This stage is optional, but we recommend it, because it will help to keep your DICE password safe. VPNīefore you can use ssh, you must be using a VPN - either the University VPN or the School's OpenVPN. (That page is for Linux, but ssh is the same on macOS and Linux.)įor background reading see connecting from outside the University - an overview. When using ssh it's important to know how to use it securely, so please read about Host Key Management. You can use this to login safely and securely to the School of Informatics from elsewhere on the internet.
To do this, we only have to access this link and download the version that corresponds to our OS.Macs come with ssh installed.
We miss an automatic updater that allows us to download the new versions automatically, therefore, we will have to download and install the new version by hand. This new version of the program is now available for Windows, macOS and Linux users. If you aren’t connected to the same Wifi, now is the time to go through the standard WiFi process. So we can connect remotely to it without having to go through the annoying step of using a screen, a keyboard and a mouse to perform this first configuration.įinally, we will also be able to configure other aspects more typical of Raspberry Pi Imager, such as if we want to play a sound when the image is finished flashing, eject the memory card or if we want to activate or deactivate telemetry. Mac/Linux Only: Securing the SSH key with chmod. In this way, for example, we can make the Raspberry Pi connect to Wi-Fi from the first time we start it, and start accepting connections through SSH. We will also be able to configure the time zone of our distro and the keyboard layout.
For example, we will be able to choose the host name that we want to give it, the data of the Wi-Fi network or if we want to have SSH enabled from the first time we start the system. From this new menu we will be able to configure the most basic parameters of our system.
