FarSync Drivers

Trouble Shooting Guide


This guide is suitable for the FarSync T-Series and USB products for Linux, where actions are version specific this is noted in the action.

For most users the FarSync Drivers product installation on Linux is quick and trouble free. There are however a very large number of versions of Linux in use together with a large number of kernel variants which can give rise to problems getting the product working correctly in all configurations. This guide has been put together by the Support team at FarSite with the aim of helping users to quickly resolve issues which have been encountered before. Many of the problems appear to have been 'one offs' but they have been included just in case.

FarSite makes every effort to ensure that installation and configuration of our products is quick and trouble free on the widest possible variety of installations. If you have any suggestions to help us achieve that aim we will be pleased to hear from you, just send an email to support@farsite.com.



Installation

Problem Symptom Possible Cause(s) Action
There are compile errors during the install process for the fsflex.c and farsync.c driver source files. From time to time the internal Kernel API's change.  This usually requires patches to be applied to the drivers to resolve the issue. Check to see if these patches are available on the support pages of the web site, or there is not patch available that fixes the error then please send the details of the error to support@farsite.com
There are no compile errors during the install process but there are unresolved symbols during link. The WAN driver may need other WAN modules to be present in the Kernel or in the Kernel Modules areas, for example the HDLC modules.  It may be possible that you are installing on a distribution that does not include these modules.  In general you won't get this error with the OEM module as it doesn't have any other dependencies. Check the install documentation for details on how to build the additional modules required.  This may require copying these modules from the Kernel source tree and updating the Makefile to build them.

If this does not resolve the issue please contact support@farsite.com
The farsync or flex driver driver does not load because there are unresolved load time references. This probably means that the required modules haven't been loaded yet. Use dmesg or cat /var/log/messages to identify the unresolved references.  This will indicate which module hasn't been loaded that the driver requires.
Check the install documentation for details on how to load the additional modules required.  This may require updating the  /etc/init.d/farsync script that loads the farsync driver.  There are comments in this file to indicate where the loading and unloading of the other modules could be placed.

If this does not resolve the issue please contact support@farsite.com
