Configuring password-free login for the MA5801

I would like to share a post about how to configure password-free login and use the RSA authentication on the MA5801-GP08.

The procedure is as follows:

1. Configure the Linux client

Run the following commands to generate public keys:

linux# ssh-keygen -t rsa -b 2048 // Generate a 2048-bit RSA public key password.

The content of the id_rsa.pub public key is as follows:

ssh-rsa

Open the public key and paste the public key to the device configuration in the following content.

2. Configurations on the MA5801

MA5801-GP08 (config)#rsa peer-public-key ssh_test 
{ <cr>|encoding-type<K> }: encoding-type 
{ enc-type<E><der,pem,openssh> }: openssh 

Command: 

rsa peer-public-key ssh_test encoding-type openssh 
Enter "RSA public key" view, and you can return the system view with 
"peer-public-key end". 

MA5801-GP08(config-rsa-public-key)#public-key-code begin
 
Enter "RSA key code" view, and you can return the last view with 
"public-key-code end". 

MA5801-GP08(config-rsa-public-key-rsa-key-code)#ssh-rsa AAAAB3NzaC1yc2EAAAADAQABA

TwJ+VMCVpIAASaiSbKrI5Nhm1BX xxx@DESKTOP-0O7DRN5 

MA5801-GP08(config-rsa-public-key-rsa-key-code)#public-key-code end 

MA5801-GP08(config-rsa-public-key)#peer-public-key end 

3. Creating a User on the MA5801

MA5801-GP08(config)#terminal user name 
User Name(length<6,15>):aidim78 
User Password(length<6,15>): 
Confirm Password(length<6,15>): 
User profile name(<=15 chars)[root]: 
User's Level: 
1. Common User 2. Operator 3. Administrator:3 
Permitted Reenter Number(0--20):20 
User's Appended Info(<=30 chars): 
Adding user successfully 
Repeat this operation? (y/n)[n]:n 

4. Configure public key authentication on the MA5801

MA5801-GP08(config)#ssh user aidim78 
{ assign<K>|authentication-type<K> }: assign 
{ rsa-key<K> }: rsa-key 
{ key-name<S><Length 1-40> }: ssh_test 
Command: 
ssh user aidim78 assign rsa-key ssh_test 


MA5801-GP08(config)#ssh user aidim78 
{ assign<K>|authentication-type<K> }: authentication-type 
{ all<K>|password<K>|password-publickey<K>|rsa<K> }: rsa 
Command: 
ssh user aidim78 authentication-type rsa 
Warning: Authentication type is set, and will be in effect next time.


MA5801-GP08(config)#
! RUNNING MINOR 2023-01-28 15:17+00:00
EVENT NAME :The managing user of the equipment logout or logon
PARAMETERS :User name: aidim78, Log mode: SSH, IP: 9.x.x.210, State: Log on


MA5801-GP08(config)#

Please check whether system data has been changed, and save data in time

Configuration console time out, please retry to log on

5. Local login to verify results

That’s all I’ve shared about the configuring password-free login for the MA5801.

I hope it’s helpful to you!
