Installing the Dropbox Client on OpenSUSE

The official Dropbox desktop client must be installed for seamless access to your Dropbox account from openSUSE. Here are the installation steps:

Step 1: Refresh zypper package manager and install dropbox package

sudo zypper refresh
sudo zypper install dropbox

This installs the latest Dropbox client from default openSUSE repositories.

Step 2: Launch client for the first time to setup Dropbox daemon

On first run, the client will download and install the proprietary dropboxd daemon process for syncing files with cloud account in the background.

You may encounter dependencies missing errors as below:

error while loading shared libraries: libatomic.so.1: cannot open shared object file: 
No such file or directory

Run the command below if you see this:

sudo zypper install libatomic1

With dependencies met, Dropbox will now download its daemon properly.

Step 3: Sign in to Dropbox account

The Dropbox desktop client will now open up a browser window prompting you sign in or create an account.

Use your credentials to sign in and allow Dropbox access to your cloud storage. This completes the authorization process for syncing your local openSUSE machine.

Once signed in, a ~/Dropbox folder is automatically created in your home directory. Any files added to this folder will be synced online.

The desktop client runs silently in the tray syncing the Dropbox folder in the background. The green check icon indicates an up-to-date state.

With this you have successfully set up the official Dropbox desktop client on your openSUSE system!

Configuring and Optimizing Dropbox Client

The Dropbox desktop client offers several customization options to better meet advanced workflow needs:

1. Selective Sync

By default, Dropbox syncs all files in your cloud account under the ~/Dropbox folder which tends to consume significant disk space.

Navigate to Preferences > Account tab and choose ‘Selective Sync‘. You can now uncheck folders you don‘t need synced locally.

This is immensely useful for freeing up local storage by excluding large media folders for instance.

2. Adjusting Sync Frequency

You can configure how often Dropbox syncs file changes under Preferences > Sync tab.

The available options are:

• As items are added/changed
• Every hour
• Every day
• Manually

Set this based on how fresh you need remote copies and activity levels on shared folders.

3. Performance Profiling

Determine sync speeds by clicking the Account tab and Run a bandwidth test.

This test will measure actual upload and download speeds for your system‘s Dropbox usage. Identify bottlenecks if transfer rates seem lower than expected.

4. Network Proxy Settings

Configure an HTTP proxy server under Preferences > Network if needed for routing Dropbox traffic in corporate environments or restricted networks.

5. Running Client on Startup

You can choose whether to auto-start the Dropbox desktop client on system startup or boot:

Auto-start on login:

Preferences > General > Start Dropbox on system startup

Selective startup sync:

While launching app, hold Shift key to toggle between:

• Start Dropbox on system startup
• Sync files on startup

This allows you to disable auto-start yet selectively sync on app launch. Useful for low-bandwidth connections.

6. Removing Dropbox Account

To uninstall your Dropbox setup from the desktop client:

1. Preferences > Account > Unlink this computer
2. Delete ~/Dropbox folder
3. Uninstall dropbox package

This completely removes Dropbox integration from your openSUSE system.

Using Selective Sync to Optimize Storage

One of the most powerful features offered by the Dropbox desktop client is Selective Sync. This allows you to choose exactly which parent folders sync to your local hard drive from the cloud account.

Some advantages of leveraging Selective Sync:

1. Save disk space by avoiding sync of large Media folders for instance

2. Faster performance as fewer files to transfer on initial sync and for incremental changes

3. Streamline focus on project folders you are actively working on

Real-World Example

Alan is a freelance content writer who uses Dropbox primarily for backing up his Documents and as a collaboration channel for clients to review articles and drafts before publishing.

His Dropbox storage currently holds:

• Documents: 5 GB of writing samples, notes and article drafts
• Photos: 10 GB of personal photo collection archives
• Media: 25 GB of movies for entertainment

Since he only actively works out of his Documents, optimizing selective sync yields:

Item	Storage	Local Sync
Documents	5 GB	Yes
Photos	10 GB	No
Media	25 GB	No

Total Space Saved Locally: 35 GB

Now Alan saves disk capacity without compromising utility!

Comparing Open Source Dropbox Alternatives

While convenient and fully featured, an oft-cited downside of the official Dropbox desktop client is its proprietary closed-source nature.

For those preferring open ecosystem integration, here is an expert comparison of leading open source tools for syncing local files with Dropbox cloud storage:

Tool	Type	Pros	Cons
Rclone	Command-line	Mature ecosystem, Encryption support, Wide provider support beyond Dropbox	Steeper learning curve
Kupfer	Desktop GUI	User-friendly, Linux-first, Handy quick-access interface	Limited scope
Usync	Command-line	Two-way sync support ideal for full replication, Portable cross-platform executable	Configuration complexity

While advanced users may prefer flexibility of CLI tools like Rclone, less technical users are better served by friendlier interfaces like Kupfer. Usync strikes a balance supporting GUI mode for most operations.

Let‘s evaluate some key advantages and limitations of each open source Dropbox alternative:

Rclone

Maturity: Rclone is likely the most well-established and audited open source file sync tool dating back to 2011. It boasts over 7000 GitHub stars and integrated with many cloud storage providers.

Speed: In independent benchmarks, Rclone achieves great upload and download performance exceeding tools like rsync. Read speeds over 200 MB/s and writes of 300+ MB/s are commonly reported.

Encryption: Critical for security conscious users, Rclone offers server-side encryption for cloud data via crypt and rclone cryptcheck. Use long chain directory IDs as passwords for robust protection.

Drawback: Being CLI-only, Rclone has a learning curve for mastery. Casual users may be better served by friendlier desktop tools.

Verdict: Ideal for devops users, system administrators, or power users comfortable on the command line. Choose Rclone for versatility across providers, performance and security.

Kupfer

Convenience: This Linux-first desktop tool offers quick access to files, apps, contacts etc via a slick hotkey-driven interface. Activate the Dropbox plugin to instantly access remote files.

Seamless: Once configured, Kupfer presents Dropbox as just another file access source. Open, edit, share Dropbox docs without disruptive context switching.

Portability: As a Python 3 app relying only Qt5 or GTK3+ for GUI, Kupfer works reliably across Linux desktops like GNOME, KDE Plasma, XFCE etc.

Scope Limit: Lightweight nature means fewer full-featured frills. Kupfer is perfect for instant file access but provides no sync, command line options etc.

Verdict: Choose Kupfer if you desire a fast no-frills desktop interface to open, send and access Dropbox files already synced using official client or other tools.

Usync

Bi-directional: Unlike rsync-based solutions, Usync focuses on two-way sync enabling updating remote cloud copies and local files from either side.

Cross-platform: Native command line usage works across Linux, Mac and Windows systems. Usync guarantees reliable replication regardless of your OS.

Encrypted: With configuration, supports encrypted storage backends for secure cloud data transfers.

GUI Available: While CLI usage dominates, Usync offers *-GTK and *-QT GUI options for friendlier usage if needed.

Drawback: Strict two-way sync model struggles with handling conflicts due to possibility of overwrite.

Verdict: Choose Usync where reliable sync of entire Dropbox folders (not just new/changed files) matters – ideal for replication, portable drive backups and similar full mirror-style workflows.

Troubleshooting Dropbox on OpenSUSE

Here are fixes for some commonly faced issues when utilizing Dropbox on the openSUSE desktop:

1. Client crashes on launch

If Dropbox app fails to start, rename existing ~/.dropbox folder and retry:

mv ~/.dropbox ~/.dropbox.old
dropbox

This resets client‘s settings and often resolves crashing scenarios.

2. Authentication failures

If you face repeated login failures, revoke Dropbox access and reconnect:

1. Head to Dropbox developer console
2. Under My Apps, choose Existing Apps
3. Locate and click on the Linux host app
4. Hit Revoke then Yes to revoke access
5. Retry client login flow on openSUSE

3. SMTP / Email notifications failing

Dropbox leverages the local SMTP server for activity email notifications. If unavailable, install and activate a local mail transfer agent like Postfix:

sudo zypper install postfix
sudo systemctl enable postfix

Verify by sending a test email using mail command.

4. Selective Sync changes not applying

For selective sync settings to apply:

1. Close Dropbox desktop client
2. Kill dropbox process killall dropbox
3. Launch client again

This forces reload and reapplication of account settings.

Securing Dropbox on OpenSUSE

Since Dropbox handles sensitive files including financial documents and identity papers, properly securing it is vital even on desktop Linux.

Follow these expert security hardening tips:

• Encrypt local Dropbox folder using VeraCrypt containers to prevent unauthorized access when device is compromised or stolen.
• Enable 2-step verification on the Dropbox account with phone+authenticator app combinations minimizing account takeover threats.
• Setup a strong Master Password for local Dropbox client data access since authentication tokens are stored locally.
• Occasionally audit Dropbox account Activity page to spot anomalous IP addresses indicative of malicious access attempts.
• Embed digital watermarks of copyright notices or usernames on sensitive documents to discourage unwarranted sharing of synced files.

Conclusion

The official Dropbox desktop client works great for seamless cloud integration on openSUSE desktops. With customized sync options, users can shape workflows aligning storage utilization, performance and collaboration needs.
