User's Manual 13. Remote Device Management
Version 4.4.0 251 MP26x/MP27x
13.4.3 Syslog
Syslog is a standard protocol for reporting and logging of messages over IP network and is
defined by RFC 3164. The device enables the service provider to configure a Syslog server
and a severity level above which errors are sent to the server. Typically, only error-level
messages should be sent to the Syslog server (in order not to flood it with irrelevant debug-
level information). For debugging, it is possible to temporarily allow logging for debug-level
messages (e.g. for SIP messages).
Many free Syslog servers exist, including Kiwi Syslog Daemon
(http://www.kiwisyslog.com).
Note: Since Syslog is used only to output messages from the device, it does not
contain any security concerns.
13.4.4 Automatic File Download
A practical, straight-forward and easy to implement method for mass configuration and
firmware update is automatic file download from a remote file server (via HTTP, FTP, or
TFTP). This method is used by many service providers.
13.4.4.1 Firmware File Download
The device's firmware files contain information about the target product type and the
firmware version information.
13.4.4.2 Configuration File Download
The device supports two configuration file formats, a *.conf file and an *.ini file. Both files
define the same parameters, but in a different format; the *.conf file has a hierarchical tree-
like structure and the *.ini file is "flat" (defining the full path for each parameter).
As with the firmware file, the configuration file can be “pushed” to the device via the Web
server or “pulled” by the device from a remote server. This section refers only to the
second option.
When the device downloads a file from a remote server, it performs the following actions:

Decrypts the file, if it is encrypted.

Checks that the file version is later than the current configuration file version (if it is not
later, the new configuration is not used).

Checks the software version with which the configuration file was created (if the file
was created with a later software version, it is not used).
