Access Your Box.com Account from Your Linode

If you’ve discovered Box then you know that it can be a great tool for storage, moving and managing files. The following tutorial helps you install and configure a free piece of software that facilitates Box access from your Linode.

Before You Begin

1. If you have not already done so, create a Linode account and Compute Instance. See our Getting Started with Linode and Creating a Compute Instance guides.

2. Follow our Setting Up and Securing a Compute Instance guide to update your system. You may also wish to set the timezone, configure your hostname, create a limited user account, and harden SSH access.

Note

This guide requires having a Box account.

Set Box’s Mount Point

The following step will create an empty directory where Box will live and all of your Box files and folders will appear. You can mount it anywhere, but /home/example_user/box will be used for this guide.

1. Create a mount point:

   mkdir ~/box
   

   Note

   If only your example_user needs access to the Box account contents, making the mount point in that user’s /home directory will be fine. If multiple system users (other than root) need access to the Box account, then the mount point should be placed in a system directory such as /mnt/box. For more info, see the davfs man page.

2. Add Box to fstab.

   The fstab (or file systems table) file is a system configuration file commonly found at /etc/fstab. It contains the necessary information to automate the process of mounting. Add an entry for your Box account:

   File: /etc/fstab

   1	https://dav.box.com/dav /home/example_user/box davfs rw,user,noauto 0 0

Configure WebDAV and User Permissions

1. Install davfs2, the WebDAV backend which is used to communicate between your Linode and Box account:

   CentOS

   sudo yum install davfs2
   

   Debian / Ubuntu

   sudo apt-get install davfs2
   

   When asked if unprivileged users should be allowed to mount WebDAV resources, choose Yes.

   Fedora

   sudo dnf install davfs2
   

2. Give your user permission to mount using davfs2. Replace example_user with your user name.

   sudo usermod -aG davfs2 "example_user"
   

3. Reboot your distro. This is the best way to be sure there are no user sessions lingering open. If there are, you’ll experience problems mounting the Box drive even after adding your user to the proper group.

   sudo reboot
   

4. SSH back into your Linode.

5. The WebDAV share exported by Box.com does not support file locks. Thus, you need to disable file locks in the davfs2 configuration file. Otherwise, you will encounter “Input/output error” while attempting to create a file.

   echo 'use_locks 0' >> ~/.davfs2/davfs2.conf
   

6. Add your Box account info to WebDAV’s secrets file, replacing both email with the email address you use to log in to your Box account and password with your Box password.

   echo 'https://dav.box.com/dav email password' >> ~/.davfs2/secrets
   

   Note

   If your password contains quotation characters (' or "), you’ll need to edit the secrets file directly in a text editor.

7. Make the secrets file readable to only its owner:

    chmod 600 ~/.davfs2/secrets
   

Mounting and Unmounting Your Box Drive

1. To mount and change into its directory:

   mount ~/box
   

2. To unmount:

   umount ~/box
   

Wrapping Up

To confirm that your Box drive is mounted:

df

The output should look similar to this:

Filesystem              1K-blocks   Used Available Use% Mounted on
/dev/root                 4122048 886316   3009636  23% /

tmpfs                      101504      0    101504   0% /run/user/1000
https://dav.box.com/dav  10485756     72  10485684   1% /home/example_user/box

To see the mount options with which your Box drive is mounted:

cat /proc/mounts | grep box

The output should show the following:

https://dav.box.com/dav /home/example_user/box fuse rw,nosuid,nodev,noexec,relatime,user_id=1000,group_id=1000,allow_other,max_read=16384 0 0

You’re done! The directory ~/box will now reflect your Box contents! The first time you access the folder it may take a few minutes for the contents to synchronize. After that, folder access is almost immediate.
