How to access a Windows shared network path from Spotfire Web Player running on Node Manager in Linux OS

Summary:

This article contains instructions on how to add access to a Windows-shared network path from a Spotfire Web Player installed on Linux OS.

Details:

To access files on a Windows network shared drive from a Linux system, you must mount the shared folder on the Linux machine and modify the Spotfire.Dxp.Worker.Host.dll.config file accordingly. This is a 2-step process:

Mount the shared drive using /etc/fstab to ensure it is automatically mounted at system startup.
Configure Spotfire.Dxp.Worker.Host.dll.config file to enable seamless access to the mounted files.

Resolution:

1. Mount a shared file path in Linux using /etc/fstab:

============================
1. Install the cifs-utils package if not present already using the below commands

sudo apt-get install cifs-utils # On Debian/Ubuntu
sudo yum install cifs-utils # On CentOS/RHEL

2. Create a Mount Point:

sudo mkdir /mnt/test

3. First, mount the share manually to check network connectivity and make sure that everything is working correctly using the below command. No errors should be thrown on running the below command. This assumes the share allows guest access.

sudo mount -t cifs //gasdspssanwin01/test /mnt/test -o guest

Replace guest with username=your_username, and password=your_password if authentication is required on your Windows network share as shown below.

sudo mount -t cifs //gasdspssanwin01/test /mnt/test -o username=your_username,password=your_password

4. Next, edit the /etc/fstab file with any editor of your choice.

sudo vim /etc/fstab

Add the following line at the end of the file, replacing placeholders with your actual values:

//gasdspssanwin01/test /mnt/test cifs username=your_username,password=your_password,iocharset=utf8,vers=3.0 0 0

5. Finally, unmount the share that we have mounted manually in step 3 using the below command
sudo umount /mnt/test

6. Once the above step is done, mount all entries in /etc/fstab using the below command:
sudo mount -a

7. Check if the share is mounted correctly by running the below command:
ls /mnt/test

8. Reboot your system to ensure the share mounts automatically at startup
==========================

2. Modify Spotfire.Dxp.Worker.Host.dll.config and specify the shared network path in the AllowedFilePaths section:

===============================
1. To whitelist a Windows path and corresponding Linux path assuming that the "test" is mounted under "/mnt/test", in Spotfire.Dxp.Worker.Host.dll.config file, the allowed file path should be mentioned with the pipe operator (|) in between Windows network share and the Linux mounted path, as follows:

<setting name="AllowedFilePaths" serializeAs="Xml">
<value>
<ArrayOfString>
<string>\\NetworkPath1\test|/mnt/test/</string>
</ArrayOfString>
</value>
</setting>

2. Please refer to the below article for steps to edit the service configuration:
