advanced maintenance commands for debugging purposes such as traces of a process or traces
specific to one component.
Using the OmniVista 8770 Audit application, the administrator can check any change that was made
on the OmniPCX Enterprise configuration. The grid view presents a summary of all the modifications:
–
Server or tool used to perform the change; the server could be:
o An OmniVista 8770 server
o An application such as Instant Communication Server
o The manager application embedded in OmniPCX Enterprise
–
Login of the user who performs the changes
Date of the modification
–
–
Action: add, update, delete
–
Type of object modified: subscriber, programmable key
–
Another Alcatel-Lucent OmniPCX broadcasting its internal changes
From the grid, the administrator can display the detail view with the new applied values.
Syslog files
With the security-by-default mechanism, the SYSLOG file is enabled on the Communication Server
and registers all network events as part of the process for preventing security issues. A record of
every event that involves the kernel, the network interface, the login, and other components seen by
the Linux system is distributed. These records are categorized by origin and severity and stored in
files (directory: /var/log (ex: messages, secure, auth.log, etc.).
The SYSLOG file keeps records or logs that concern:
–
Connections (who connected, and at what time)
The Kernel and registration of the daemons used on devices
–
–
Unauthorized attempts to enter the system
History of system commands used
–
Log files are dynamic and can vary widely in resource utilization. To avoid congestion on the disk
caused by these files, an automatic mechanism rotates the log files. They are compressed and
renamed by this mechanism.
The rotational schedule is weekly and/or when the file exceeds 500 Kb (before compression). In
concept, SYSLOG is a straightforward tool used to send small textual messages (usually less than
1024 bytes) to a logging server via UDP and/or TCP. In the most common configurations, SYSLOG
messages are sent across a network in an unencrypted clear text form, but options do exist to use
SSL/TLS services to transport SYSLOG messages in encrypted form.
1.8 Launching external applications
External applications (exe file or browser) can be launched in a separate window from the client.
Access to these applications is controlled by the OmniVista 8770 security agent.
1.9 Maintenance
The Maintenance application provides:
–
Immediate or scheduled backup for one or for a set of OmniPCX and OpenTouch.
–
Immediate or scheduled software update for one or for a set of OmniPCX.
