Two user roles have been defined:

  • viewer for use in operational mode where the configuration cannot be changed, only commands to troubleshoot or monitor are available. All users have this role by default.
  • admin for use in configuration mode, with full access.

Two default users are created when booting the system for the first time: admin and viewer. Their default passwords are admin and viewer, respectively.

The admin account has the admin role, which means that it has permissions to edit the configuration and run privileged commands.

The viewer acccount has the viewer role, which means that it has permissions to view the configuration but not to edit it and run standard commands.


For obvious security reasons, you MUST change the passwords of these users.

You may even want to completely disable the default admin and viewer users, by setting default-users-enabled to false:

vrouter running config# system auth default-users-enabled false
vrouter running config# commit
Configuration applied.

In this case, you must configure a user with the admin role, else you will lose access to the CLI.

Changing Passwords

To change the admin user password, go in the system auth user admin context:

vrouter running config# system auth user admin
vrouter running user admin# password
Enter value for password> **********
vrouter running user admin# commit
Configuration applied.

For security reasons, the password is not stored in clear-text in the configuration. A hash is stored instead.

vrouter running user admin# show config
user admin
    password $5$Ndx/QlMS5Anp7LTq$Lws2OmAm0SO.cBmPBGtdpwnfdAM4hDM4AdSO4ncXjS/

It is also possible to directly set the password as a hashed value. To generate a hashed password on a Linux machine, use mkpasswd, which is provided in the whois package:

root@host:~# mkpasswd -m SHA-256
Password: **********

Creating Users

To create a new user, go into the config system auth context, and add a new user with the following commands:

vrouter running user admin# ..
vrouter running auth# user john
vrouter running user john# role admin
vrouter running user john# password
Enter value for password> **********
vrouter running user john# commit
Configuration applied.

Let’s display what has been sent to the NETCONF server:

vrouter running user john# show config xml absolute
<config xmlns="urn:6wind:vrouter">
  <system xmlns="urn:6wind:vrouter/system">
    <auth xmlns="urn:6wind:vrouter/system/auth">

Now that the configuration is applied, let’s see the state of our user:

vrouter running user john# show state
user john
    password $5$iqsVCbCmIYRF.Sht$lCwP.HDLxtTnzz33uXX7ZdTR6xdSdnUoabRMxHYXjI9
    role admin

The user john has the admin role. This means he can edit the configuration, read protected nodes (such as passwords) and run privileged commands.

Configuring SSH Authorized Keys

If you want, you may enable SSH authentication without using a password by configuring one or more authorized-key. First, you need to generate a key pair on a remote machine.

user@my-laptop:~$ ssh-keygen -t ecdsa
Generating public/private ecdsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_ecdsa):
Enter passphrase (empty for no passphrase): ********
Enter same passphrase again: ********
Your identification has been saved in /home/user/.ssh/id_ecdsa.
Your public key has been saved in /home/user/.ssh/
The key fingerprint is:
SHA256:UrMHdqPxmoeV8DNYRtL0Il5cWAFfzZn7PHy4j2enH5A robobuild@ubuntu1604es
The key's randomart image is:
+---[ECDSA 256]---+
|        .o+++..oo|
|         +o+ . oo|
|        O O o   .|
|       + ^ +  .. |
|      . S O  E.o.|
|       . * o  oo+|
|        + .    oo|
|         .    ..=|
|              o*+|

Then, copy the public key file contents into the configuration:

user@my-laptop:~$ cat ~/.ssh/
ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBH2hK42JHtTYU1XRw2Zu4xCriM7CIXBl19p1/1qkapobkS6yCnwauqTEveBw1GOjwuTADvqQVozBoaLbY3KGmsI= user@my-laptop
vrouter running user john# authorized-key "ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBH2hK42JHtTYU1XRw2Zu4xCriM7CIXBl19p1/1qkapobkS6yCnwauqTEveBw1GOjwuTADvqQVozBoaLbY3KGmsI= user@my-laptop"
vrouter running user john# commit
Configuration applied.


NEVER copy the private key contents. Only the PUBLIC key.

After which you may check that the remote authentication works without a password:

user@my-laptop:~$ ssh -i ~/.ssh/id_ecdsa john@vrouter
The authenticity of host 'vrouter (' can't be established.
ECDSA key fingerprint is SHA256:nNerPB16BKwHmcex5IVKS7YMVt4VuaVavH3LId7uI6Q.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'vrouter,' (ECDSA) to the list of known hosts.
Enter passphrase for key '/home/user/.ssh/id_ecdsa': ********
Welcome to Turbo Router - 2.0



If you did set a passphrase on your private key, you will need to enter it.
