Search online for a tutorial on creating and using SSH key pairs, here are a few.
ssh-keygen instructions from oracle
Once SSH key pairs are created, perform the following steps to enable this feature for your VCL account.
- Go to your VCL User Preferences
- Select General Preferences
- Click the Enabled radio button under Use public key authentication for SSH logins
- Paste the contents of your public key file in the Public keys box
- Click the Submit General Preferences button.
On your next VCL reservation, your public key will be inserted onto the assigned machine.
NOTE: This change will not be applied to existing reservations.
To test this change, make a new reservation. When connecting to your reservation, specify the private key that matches the public key you used in the previous steps when you attempt to make an SSH connection with the VCL image.
If you are using a Linux or Mac machine to connect with the VCL image you can use the following SSH syntax in a terminal window.
ssh -i
...
<path_to_private_ssh_key>
...
<username>@<ipaddress>
...
Replace
...
<path_to_private_ssh_key>
...
with
...
the
...
actual
...
directory
...
path
...
to
...
your
...
private
...
ssh
...
key
...
(e.g.
...
.ssh/id_rsa).
...
Replace
...
<username>
...
with
...
your
...
actual
...
username.
...
Replace
...
<ipaddress>
...
with
...
the
...
IP
...
address
...
of
...
the
...
VCL
...
image
...
listed

be

using

Putty

for

your SSH

you
