Uploading with SCP
It is possible to upload new HTTP Banner files using SCP. The steps to do this are:
1. Since SCP cannot be used to download the original default HTML, the source code must be
first copied from the WebUI and pasted into a local text file which is then edited using an
appropriate editor.
2. A new ALG Banner Files object must exist which the edited file(s) is uploaded to. If the
object is called mytxt, the CLI command to create this object is:
gw-world:/> add HTTPALGBanners mytxt
This creates an object which contains a copy of all the Default content filtering banner files.
3. The modified file is then uploaded using SCP. It is uploaded to the object type
HTTPALGBanner and the object mytxt with the property name URLForbidden. If the edited
URLForbidden local file is called my.html then using the Open SSH SCP client, the upload
command would be:
scp myhtml admin@10.5.62.11:HTTPAuthBanners/mytxt/URLForbidden
The usage of SCP clients is explained further in Section 2.1.6, “Secure Copy”.
4. Using the CLI, the relevant HTTP ALG should now be set to use the mytxt banner files. If the
ALG us called my_http_alg, the command would be:
