you will not be able to hear audio over this link as the VNC Protocol does not
provide audio forwarding.) To use VNC, you must first enable the service by
selecting the relevant check box on this page, and enter a password that VNC
Clients will be expected to provide in order to gain access. The password must
be entered twice to make sure it is entered correctly.
4.5.4. VPN Settings
NexLog is capable of joining a VPN (Virtual Private Network) to make the
recorder accessible via the internet to Eventide technicians in the case
assistance is required. Here you can enable that setting and enter the port and
host, which would be provided by Eventide if necessary.
4.5.5. SNMP Settings
SNMP stands for “Simple Network Management Protocol” and provides a
standard mechanism for System Administrators to manage devices over an IP
Network. Many third party commercial and free utilities and consoles exist for
monitoring systems using the SNMP Protocol. Eventide NexLog provides a
simple subset of SNMP Functionality (with Linux and SQL notifications) which
can be configured here. First, you must choose to enable SNMP on the recorder
and provide a community to join. An SNMP community is similar to a
Workgroup. Only SNMP Clients in the same community will be permitted to
query the recorder via SNMP to retrieve information.
In addition to allowing third party utilities to monitor basic recorder status, you
can configure an SNMP Trap, upon receiving which, the recorder will shut down.
This can be used with a UPS which can be configured to generate a trap upon
power failure (Though Eventide recommends using one of the UPS’s listed earlier
in this manual which provides a USB connection to the recorder, since more
information is available to the recorder in that case). If this feature is used, the
system generating the trap must be a member of the same community as the
recorder. In addition, you can limit what IP address the recorder will allow the
trap to be sent from by replacing the ‘*’ (meaning any) with the IP address in the
“Trap from IP’ field. Finally you must provide the OID (Object Identifier) of the
trap upon which you wish the recorder to shut down upon receiving, in the
“Trap from OID” box.
4.5.6. Packet Capture
Packet Capture is a diagnostic tool that allows you to easily capture a record of
network traffic for analysis in a third party application such as Wireshark. You
may be asked to use this feature in the course of a support call in order to allow
Eventide to troubleshoot a networking or IP call situation.
