NetDefendOS File organization
NetDefendOS maintains a simple 2 level directory structure which consists of the top level root and
a number of sub-directories. However, these "directories" such as sshlclientkey should be more
correctly thought of as object types. All the files stored in the NetDefendOS root as well as all the
object types can be displayed using the CLI command ls.
The resulting output is shown below:
gw-world:/> ls
HTTPALGBanners/
HTTPAuthBanners/
certificate/
config.bak
full.bak
script/
sshclientkey/
Apart from the individual files, the objects types listed are:
• HTTPALGBanners/ - The banner files for user authentication HTML. Uploading these is
described further in Section 6.3.4.4, “Customizing HTML Pages”.
• HTTPAuthBanner/ - The banner files for HTML ALG dynamic content filtering. Uploading
these is described further in Section 6.3.4.4, “Customizing HTML Pages”.
• certificate/ - The object type for all digital certificates.
• script/ - The object type for all CLI scripts. Scripts are described further in Section 2.1.5, “CLI
Scripts”.
• sshclientkey/ - The SSH client key object type.
Examples of Uploading and Downloading
In some cases, a file is located in the NetDefendOS root. The license file (license.lic) falls into this
category, as well as backup files for configurations (config.bak) and the complete system (full.bak).
When uploading, these files contain a unique header which identifies what they are. NetDefendOS
checks this header and ensures the file is stored only in the root (all files do not have a header).
If an administrator username is admin1 and the IP address of the NetDefend Firewall is 10.5.62.11
then to upload a configuration backup, the SCP command would be:
> scp config.bak admin1@10.5.62.11:
To download a configuration backup to the current local directory, the command would be:
> scp admin1@10.5.62.11:config.bak ./
