Secure Copy - D-Link DFL-1660 User Manual

2.1.6. Secure Copy

then uploaded and executed on the other NetDefend Firewalls. The end result is that all units will
have the same IP4Address objects in their address book.
The name of the file created using the -create option cannot be greater than 16 characters in length
(including the extension) and the filetype should be .sgs.
Certain aspects of a configuration which are hardware dependent cannot have a script created using
the -create option. This is true when the CLI node type in the script -create command is one of:
COMPortDevice
Ethernet
EthernetDevice
Device
If one of these node types is used then the error message script file empty is returned by
NetDefendOS.
Commenting Script Files
Any line in a script file that begins with the # character is treated as a comment. For example:
# The following line defines the If1 IP address
add IP4Address If1_ip Address=10.6.60.10
Scripts Running Other Scripts
It is possible for one script to run another script. For example, the script my_script.sgs could contain
the line:
"
"
script -execute -name my_script2.sgs
"
"
NetDefendOS allows the script file my_script2.sgs to execute another script file and so on. The
maximum depth of this script nesting is 5.
2.1.6. Secure Copy
To upload and download files to or from the NetDefend Firewall, the secure copy (SCP) protocol
can be used. SCP is based on the SSH protocol and many freely available SCP clients exist for
almost all platforms. The command line examples below are based on the most common command
format for SCP client software.
SCP Command Format
SCP command syntax is straightforward for most console based clients. The basic command used
here is scp followed by the source and destination for the file transfer.
Upload is performed with the command:
> scp <local_filename> <destination_firewall>
Tip: Listing commands at the console
To list the created CLI commands on the console instead of saving them to a file, leave
out the option -name= in the script -create command.
