27.2.9.3  Secure FTP Using SSH Example
This section shows an example on file transfer using the OpenSSH client program. The 
configuration and connection steps are similar for other SSH client programs. Refer to your 
SSH client program user’s guide.
Enter “sftp –1 192.168.1.1”. This command forces your computer to connect to 
the ZyWALL for secure file transfer using SSH version 1. If this is the first time you are 
connecting to the ZyWALL using SSH, a message displays prompting you to save the 
host information of the ZyWALL. Type “yes” and press [ENTER].
Enter the password to login to the ZyWALL. 
Use the “put” command to upload a new firmware to the ZyWALL.

27.3  The WWW Screen    
Use this screen to configure the ZyWALL’s HTTP and HTTPS management settings. 
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web 
protocol that encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-
level protocol that enables secure transactions of data by ensuring confidentiality (an 
unauthorized party cannot read the transferred data), authentication (one party can identify the 
other party) and data integrity (you know if data has been changed). 
It relies upon certificates, public keys, and private keys (see 
 
for more 
information).
HTTPS on the ZyWALL is used so that you may securely access the ZyWALL using the web 
configurator. The SSL protocol specifies that the SSL server (the ZyWALL) must always 
authenticate itself to the SSL client (the computer which requests the HTTPS connection with 
the ZyWALL), whereas the SSL client only should authenticate itself when the SSL server
