Specify a service type for an 
SSH user 

ssh user username 
service-type { stelnet | sftp | 
all } 

Required 

By default, an SSH user can 
use the service type of stelnet.

 

If the ssh user service-type command is executed with a username that does not exist, the system will 

automatically create the SSH user. However, the user cannot log in unless you specify an 

authentication type for it. 

 

 

This configuration is not necessary if the password authentication mode is configured for SSH users. 

 

With the publickey authentication mode configured for an SSH client, you must configure the client’s 

RSA or DSA host public key(s) on the server for authentication.  

You can manually configure the public key or import it from a public key file. In the former case, you can 

manually copy the client’s public key to the server. In the latter case, the system automatically converts 

the format of the public key generated by the client to complete the configuration on the server, but the 

client’s public key should be transferred from the client to the server beforehand through FTP/TFTP. 

Follow these steps to configure the public key of a client manually: 

Enter system view 

— 

Enter public key view 

public-key peer keyname 

Required 

Enter public key edit view 

— 

Configure a public key for the 
client 

Enter the content of the public 
key 

When you input the key, 
spaces are allowed between 
the characters you input 
(because the system can 
remove the spaces 
automatically); you can also 
press Enter to continue your 
input at the next line. But the 
key you input should be a 
hexadecimal digit string coded 
in the public key format.
