they are retrieved from a remote FTP client, or until the system needs to create more space
for log files.

Configuring Host Keys
Use the
logconfig -> hostkeyconfig
subcommand to manage host keys for use with
SSH when pushing log files to other servers from the Web Security appliance. SSH servers
must have a pair of host keys, one private and one public. The private host key resides on the
SSH server and cannot be read by remote machines. The public host key is distributed to any
client machine that needs to interact with the SSH server.
