Meinberg LANTIME, Operating Instructions Manual

Page: 93 / 153

The function “Reset to factory defaults“ is setting all configuration parameters back
to default values. The regular file /mnt/flash/global_configuration will be replaced
with the file /mnt/flash/factory.conf, but first a copy of the configuration is saved
under /mnt/flash/global_configuration.old for backup reasons. The default password
“timeserver” is replacing the actual password, too. After using this function, all
certificates should be recreated because of the change of the unit’s hostname.
Please be aware of the fact that the default configuration is not activated instantly. If
you want to avoid setting up the IP address of your unit by locally configuring it on
site with the buttons of the front panel (meaning physical presence of someone
directly at the location of the LANTIME), you have to configure the network
parameters of your LANTIME immediately after using the “reset to factory defaults”
button. So, please proceed directly to the Ethernet page and check/change the IP
address and the possible access subsystems (HTTP for example) of the LANTIME.
The first usage of “Save settings” will load the configuration from flash into memory
and activate it.
User Management
For administration different users can be set up. 3 group memberships can be
assigned to each user: the Super-User has all properties for administration. The group
membership Administrator can change all parameters via the command line interface
(CLI) configuartion tool and the WEB interface. The group Administrator cannot use
any Linux command in a Telnet, SSH or Terminal session. If the Administrator will
login, the setup program will be started directly. After termination of the Setup
program this user will be logout automatically. The group membership “Info“ has the
same properties like the Administrator but cannot change any parameter.
The menu “User Management“ allows you to set up different users with a password
and the group membership. To change the properties of an user you have to delete the
old user and set up a new one. The user “root“ cannot be deleted and has always the
membership of Super-User. The password of the user “root“ can be set on the security
page.
Administrative information
The button “List all messages“ displays the SYSLOG of the LANTIME
completely. In this log all subsystems create their entries, even the OS kernel. The
SYSLOG file /var/log/messages is only stored in the system’s ram disk, therefore it is
lost after a power off or restart. If you configured an external SYSLOG server, all
LANTIME SYSLOG entries will be duplicated on this remote system and can be
saved permanently this way.
