SSH Access

Synpse allows you to ssh into the edge. You can access your devices anywhere where they are.

Accessing device via dashboard
Synpse allows you to connect to the device via the SSH directly from the browser:
​
Accessing device via CLI
First, to list your devices:
synpse devices
​
 NAME  STATUS  IP             OS      LABELS      LAST SEEN     CREATED      |
 nuc   online  192.168.1.120  Ubuntu  arch:amd64  1 second ago  23 hours ago |
​
To access your device from the CLI:
synpse ssh <device name>
Native SSH client
Synpse supports native ssh clients too. So you can use tools like SCP or Ansible more easily with your devices. Native ssh client supports 2 modes of authentication:
1.Username/password
2.SSH keys
Username/Password auth
You can ssh to any device using the syntax below. Password for this is is Access key or Service account access key
RBAC is still applicable to these connections. User in question should have "Resource: Device, Action: SSH" in their role bindings for authentication.
ssh <device_id>@ssh.synpse.net
Example:
ssh [email protected]
SSH key authentication
To authenticate using SSH keys you need to add public  SSH key into your account. This can be done via UI SSH Keys section or CLI synpse ssh-keys add <key-name> -k <path-to-public-key>
Or synpse CLI can do this for you. Just run synpse ssh-keys configure and it will generate key pair into .ssh folder and add it to the current synpse session.
synpse ssh-key configure
  NAME         SSH KEY                       CREATED               LAST USED             
  unknown-cli  ecdsa-sha2-nistp521 AAAAE...  112 milliseconds ago  112 milliseconds ago  
Authentication:
ssh <device_id>@ssh.synpse.net
Authentication shortcut
We understand that these names are hard to remember and to use. For this CLI will manage part of the.ssh/config file. If you have a synpse SSH key configured using synpse ssh-keys configure and you execute native ssh command synpse ssh <device_name> ssh config will be updated with all the required details. See the example below:
# configure cli ssh key
synpse ssh-keys configure
​
# SSH using native CLI client
synpse ssh minis
​
# check your .ssh/config file
cat ~/.ssh/config
....
​
# SSH using short command!
ssh minis
Due to security reasons, Synpse does not support RSA ssh keys. Use ECDSA keys.
Example how to generate ECDSA key pair:
ssh-keygen -t ecdsa -b 521

Where is a way to prevent anybody with access to SSH into the devices? This can be done using RBAC or via ssh key checking. Documentation is coming, but if you need this now - ping us on Discord
