6.2 Upload SSH keys  

The first time a device is accessed via SSH by a host, its IP should be added to the known hosts 

list as illustrated below. Then the password corresponding to the root user will be asked (default 

password is ‘

root

’

 as detailed in 0).  

 

ssh [email protected] 

The authenticity of host ‘192.168.7.35 (192.168.7.35)’ can’t be 

established. ECDSA key fingerprint is 
SHA256:YgGTNfRPHYH4ekrJxDSHl7460dSs. 
Are you sure you want to continue connecting (yes/no)? Yes 

Warning: Permanently added ‘192.168.7.

hosts. 
Welcome to WR-ZEN  
wr-zynq-os version: v3.2-RC1 
root@zen-425:~# 

 

This authentication procedure will only need to be confirmed the first time and will not be asked 

in the later connections.

Welcome to WR-ZEN 
wr-zynq-os version: v3.2-RC1 
root@zen-425:~# 

 

In order to improve security, it is strongly recommended to upload your public key to the device 

instead of using a password. 

 

This can easily be done by running the command: 

 

ssh-copy-id root@<device_ip> 

 

This  setting  is  also  available  in  the  Expert  mode  of  the  GUI  under 

Security  > 

Authentication  >  SSH  public  key  only  (disable  password)

. Choose Yes in the 

field, Save, and Reboot your device to activate changes.  

6.3 HTTPS  

Hypertext Transfer Protocol over TLS (HTTPS) is the encapsulation of HTTP over a Transport Layer 
Security (TLS) secured channel, which is the primary protocol used to send data between a web 
browser and a website.
