DHCP/Telnet/SSH 
Dynamic Host Configuration Protocol (DHCP) is a communications protocol that lets network 
administrators manage centrally and automate the assignment of Internet Protocol (IP) addresses in an 
organization's network. Default setting is DISABLED. 
 
 
 
Telnet is a user command and an underlying TCP/IP protocol for accessing remote devices. On the 
Web, HTTP and FTP protocols allow you to request specific files from remote computers, but not to 
actually be logged on as a user of that computer. Default setting is ENABLED.  
 
 IMPORTANT: Changing this setting will logout all SSH and Telnet sessions 
 
 
 
Secure Shell (SSH), sometimes known as Secure Socket Shell, is a Unix-based command interface and 
protocol for securely getting access to a remote computer. It is widely used by network administrators 
to control Web and other kinds of servers remotely. Default setting is ENABLED
 
 IMPORTANT: changing this setting will logout all SSH and Telnet sessions 
 
 
SSH Host Key Generation 
Selecting this option allows the user to generate a unique SSH host key for the DS unit. This key is 
part of the SSH encryption process. Each DS leaving Baytech is shipped with same default SSH host 
key. It is important that the user generate a new SSH host key if SSH communications will be used.  
 
 NOTE: It can take the DS up to 10 minutes to generate a new host key. 
 
 
IP Filter Configuration 
The IP Filter Management Menu allows the admin user to pass or block certain IP Addresses.  
If you have no rules defined the DS may display only options (A, E, C).
