2.1.7. 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>
Download is done with the command:
> scp <source_firewall> <local_filename>
The source or destination NetDefend Firewall is of the form:
<user_name>@<firewall_ip_address>:<filepath>.
For example: admin@10.62.11.10:config.bak. The <user_name> must be a defined NetDefendOS
user in the administrator user group.
Note: SCP examples do not show the password prompt
SCP will normally prompt for the user password after the command line but that prompt
is not shown in the examples given here.
The following table summarizes the operations that can be performed between an SCP client
and NetDefendOS:
File type Upload possible Download possible
Configuration Backup (config.bak) Yes (also with WebUI) Yes (also with WebUI)
System Backup (full.bak) Yes (also with WebUI) Yes (also with WebUI)
Firmware upgrades Yes No
