You will need to create an SSH key pair for communication with your AXIOM Beta camera over Ethernet if you don't already have one.
By default, the ssh directory is located at
~/.ssh, and contains key files called
id_rsa.pub, respectively. Check if the directory exists and already contains keys by listing its contents:
$ ls -al ~/.ssh
If the directory doesn't exist or is empty and you don't have your SSH keys stored elsewhere on your machine, follow the instructions for key creation below.
Linux machines as well as new Macs usually come pre-installed with the tools you need for creating SSH keys. To start the key creation process, use the command:
$ ssh-keygen -t rsa -b 4096 -C "yourname@yourmachine"
-C argument is used to add a comment which can help indentify your key as yours/your machine's, which might come in handy once you use other computers to connect to your Beta camera. If you leave it out, your default username/hostname will be used (you can check with
$ echo "$(whoami)@$(hostname)" either beforehand or in another Terminal window to find out what it is), though you can always change the comment part again later on.
You will be prompted for a file in which to save the keys. To use the default install location (recommended), just press Enter.
Next, you will be asked to enter a passphrase. Using a passphrase means greater security, though you can continue without one by just pressing Enter. In either case you will be asked to confirm your passphrase (by re-entering it if you used one, or pressing Enter again in case you did not).
Subsequently, your keys will be created and saved in the directory you specified (
~/.ssh by default). You can have your machine print out your public key for you by using the command:
$ cat ~/.ssh/id_rsa.pub
The output will look approximately like this:
ssh-rsa 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 anne@farragut
Note that in newer Ubuntu versions (tested with 16.04) it seems that the newly created key is not loaded by the keyserver until you manually run:
