OTMC 100 Series User Manual
8
Automation Interface
The OTMC 100 series offers secure shell (SSH) access to its internal Linux operating system for
remote configuration.
It provides the following functionality:
•
Configuration management (backup and restore)
•
Download of log files
•
Usage of Linux shell utilities (e.g. ping)
8.1
Access
The OTMC 100 supports TFTP, FTP and SSH access. By default you can login via FTP/SSH using
the user name omicron and the password timeserver. The Web Interface, the SSH, and the FTP
server use the same password. Therefore, changing the password in the Web Interface will also
update the password for the other services.
Anonymous access is possible via TFTP and FTP, however, without the option to upload files. In order
to upload files, we recommend the secure SCP (Secure Copy) instead of FTP, where passwords are
not transmitted in plain text. Note that the TFTP and FTP services can also be disabled if not needed.
The log and configuration files are located in the home directory of user omicron ("/home/omicron") in
the respective subfolders "config" and "log".
8.2
Configuration
All configuration options are stored in a single XML file that can be edited easily. The XML file contains
the same options as the Web Interface (which is in fact just a front end for the XML file). Additionally,
an XML Schema Definition (XSD) is provided to ensure that only valid configuration options are set.
This makes it possible to easily clone a device even from distant locations. Just download the
configuration file from one OTMC 100, edit it if required (e.g. change the IP address) and upload it to
another OTMC 100.
Further instructions regarding the automated configuration via SSH can be found in the readme file
located under "/home/omicron/doc/readme.txt".
