Configuration through the web interface

175

Change the password for administrative user

To increase security, change the password for the administrative user from its default. By default,

the administrative username is root.

Note

Record the new password. If the changed password is lost, the Digi device must be

reset to the default firmware settings.

In Digi devices with a single-user model, changing the root password also changes the password

for Advanced Digi Discovery Protocol (ADDP). In Digi devices with the multi-user model,

changing the root password has no effect on ADDP. To change the ADDP password, enter

newpass name=addp from the command line.

In the web interface:

1 On the Main menu, click Users.

2 On the Security Configuration page, enter the new password in the New Password and

Confirm Password edit boxes. The password can be from 4 through 16 characters long and

is case-sensitive. Click Apply.

3 A logoff is forced immediately. Log in to the web interface using the new values.

From the command line:

Issue the newpass command.

Upload an SSH public key

SSH can be configured to log into to servers without having to provide a password. This is called

“public key authentication” and is more secure than using a normal password.

You generate a public/private key using a program called ssh-keygen, and store a copy of the

public key on the server(s) that you wish to use for authentication. When you attempt to log in, the

server sends you a message encrypted with your public key. Your machine decrypts it and sends

back the original message, proving your identity.

To upload an SSH public key:

1 On the Main menu, click Security.

2 On the Security Configuration page, check the Enable SSH public key authentication

check box.

3 Type or paste the SSH public key in the edit box.

4 Click Apply.
