Figure 6.24: Successful firmware update
The configuration settings of the LANTIME will be preserved during a firmware update, except the config-
uration files of the web server and the SSH service. These files will be overwritten during an update to be
able to deliver current cryptographic methods with an update. If, contrary to our recommendation, the automatic
update is not desired, a separate customer-specific configuration file can be stored for these services.
SSH configuration:
The configuration file /etc/ssh/ssh.cfg defines which configuration file the SSH service should use. In factory
configuration the file contains the following entry:
[SSHD]
CONFIGFILE=/etc/standard/sshd_config
If the file
/etc/standard/sshd_config
is defined as an SSH configuration file, this file is updated during a
firmware update. If the file
/etc/ssh/sshd_config
is entered, an own configuration can be created in this file,
which is not replaced during an update.
Web server configuration:
The configuration file
/etc/webUI/webUI_custom.cfg
defines which configuration file the web server should use.
In the factory configuration the file contains the following entry:
[CUSTOM CONFIGURATION]
CUSTOM_CONFIG_PATH=
