Troubleshooting Firewalls and Interplay
228
Check the speed of the LAN between the Interplay Engine and the shared storage server.
Make sure that the Interplay Engine and the Avid shared-storage server are connected
appropriately; for example, the Interplay Engine needs to read the files to create thumbnails.
If the connection is slow, performance can drop.
Check the speed of file operations of the Interplay Engine on the shared storage server.
Make sure that the Interplay Engine can move data quickly on the Avid shared-storage
system. Log in to the Interplay Engine server and use Windows Explorer to transfer files
from an Avid shared-storage workspace to the Interplay Engine server. The speed
performance of these operations should be independent of file size and instantaneous. Make
sure the connectivity and credentials are correct.
Troubleshooting Firewalls and Interplay
Firewalls on client machines interfere with Interplay’s TCP/IP communications.
Symptoms
The list of servers does not appear, for example, when you are connecting to a new database.
Connection establishment to the server fails.
Cause
These problems can be caused by personal firewalls installed on the client machine. A typical
example for such a firewall is ZoneAlarm
®
from ZoneLabs
or the Windows XP firewall.
These applications intercept all outgoing and incoming network traffic and decide whether to let
the traffic go through or block it. The effect is that applications like Interplay fail to connect to
their servers.
Typically when the client looks for available Interplay Engines in the network, no servers can be
retrieved. When the client is looking for servers, a UDP broadcast is sent out on port 8321.
Solution
Usually these personal firewalls can be configured to allow all network traffic for specific
applications. This should be done for Interplay locally or for Internet access depending on which
servers Interplay should connect to.
For information about ports used by Interplay, see
“Required TCP/IP Ports” on page 255 and
“Interplay Port Usage” in the Interplay Software Installation and Configuration Guide.
