If you are having problems with the software installation, check the following:
Install Script Reports Errors
If you see messages like:
ln: creating symbolic link ‘/etc/init.d/rc0.d/K91farsync’ to ‘/etc/init.d/farsync’
No such file or directory
Then it is possible that you are using a Linux distribution that we have not tested our installation process with yet.
At this point in the script, we are trying to install System V startup and shutdown scripts for the various run levels. If you have encountered this error, then when the installation completes, the startup/shutdown scripts will be missing, and therefore when you reboot the system the FarSync card will not be loaded with low level driver software or be configured. (This will be indicated by the Green LED’s on the FarSync card near the connector being in an off state after you have rebooted the system).
This problem can occur if your distribution uses a BSD like method to boot the system. BSD uses a small number of scripts to configure the system software. In this case you need to place the following command in a startup file (e.g. /etc/rc.d/rc.local , or similar)
farutil hdlc0 load /etc/farsite/downloads/trtbios.cde /etc/farsite/downloads/farsynu2.cde
You will need to add one farifup command to the startup file for each port you want to configure.
If you see any other error message while running the install script, please let us know.
Check PCI card detected
Assuming that the mechanical installation id OK you can check whether the system has detected the card by running the lspcicommand:
[root@minion doc]# lspci 00:00.0 Host bridge: VIA Technologies, Inc. VT82C598 [Apollo MVP3] (rev 04) 00:01.0 PCI bridge: VIA Technologies, Inc. VT82C598/694x [Apollo MVP3/Pro133x AGP] 00:07.0 ISA bridge: VIA Technologies, Inc. VT82C586/A/B PCI-to-ISA [Apollo VP] (rev 47) 00:07.1 IDE interface: VIA Technologies, Inc.

Check device driver is being run
Watch the startup sequence carefully. When the FarSync device driver is first loaded four lines like this will appear:
May 19 10:30:12 odeon kernel: FarSync WAN driver 1.08.07-00-ia32 (c) 2001-2007 FarSite Communications Ltd. May 19 10:30:12 odeon kernel: hdlc0-hdlc3: (X0000001) FarSync T4U IRQ5, 4 ports May 19 10:30:12 odeon kernel: fst: Initialising flex tty driver May 19 10:30:12 odeon kernel: Flex USB WAN driver 1.08.07-00-ia32 (c) 2007 FarSite Communications Ltd. May 19 10:30:12 odeon kernel: hdlc4-hdlc4: (U0010083) FarSync Flex-1, 1 port
The first and last line are from the FarSync driver and the middle two from the syncPPP module. If the syncPPP module has already been loaded by another driver the middle two lines may appear elsewhere in the startup messages instead.
The last line is the most important it indicates the card detected and the ports that have been assigned to it. If more than one card is installed then the last line will be repeated with values for each card.
These messages can also be viewed after startup by using the command:
$ dmesg | more
If the card is installed as indicated by the lspci command yet the device driver message is not apparent the most likely cause is that you are running a kernel without the device driver built in correctly or where the module is not being loaded correctly.
Check the kernel build and installation and that the correct kernel is being bootstrapped by lilo. It’s easy for a new build not to be registered by lilo if you’ve performed a kernel upgrade at the same time as installing the FarSync software. To be absolutely certain they you are running the correct kernel modify the EXTRAVERSION entry in /usr/src/linux/Makefile, rebuild and then check for it with uname -r. Alternatively uname -v will give you the kernel build date and time.
Check module loaded
If the device driver was built as a module then you can check whether it has been loaded by using the lsmod command.
# lsmod Module Size Used by fsflex 36304 0 farsync 51824 0 syncppp 17856 1 hdlc_ppp hdlc 8836 3 fsflex,farsync,hdlc_ppp
This shows the farsync module has been loaded and that in turn it has caused the hdlc and syncppp module to be loaded. (The pcnet32 entry is for an unrelated Ethernet driver.)
If the modules have not been loaded check the sync0 alias entries in /etc/modules.conf
Check card detection and download OK
You can check the status of the firmware using the farutil command, response for a FarSync T4U card shown.
root@odeon:/etc/farsite/farsync# farutil hdlc0 card: T4U FarSync T-Series ports: i state: Running normally firmware id: 5 firmware vers: 1.02.03 Async ports present Configuration for port 0 physical: V.24 (RS232C) cable status: Cable presence detected active inputs: None active outputs: None clock: External, Not detected speed: 9600 protocol: Unknown generic HDLC code 0x0005 Buffer configuration: no of rx buffers: 8 size of rx buffers: 8192 no of tx buffers: 8 size of tx buffers: 8192 root@odeon:/etc/farsite/farsync#
The information that is most important is the state: line which gives the current firmware status. If this is not Running normally then check the system startup messages for possible download error messages. You could also run the system startup script manually to check for errors.
The Kernel is configured OK but the card is not loaded
You have verified that you can manually load the FarSync card, but the card does not seem to load after a reboot.
This problem can occur if you do not have an ifcfg-hdlc0 file. Please make sure that this file exists, even if you do not use Port A.
