How to Use the Command 'waypipe' (with examples)

Waypipe is a tool designed to facilitate the remote execution of graphical applications on systems employing the Wayland display server protocol. By leveraging SSH, it securely transmits application outputs from a remote server to a local client, enabling users to interact with applications running on different machines. This can be particularly useful for accessing software resources on a remote system without losing the graphical interface. More information can be found on its official page at Waypipe GitLab .

Use case 1: Run a graphical program remotely and display it locally

Code:

waypipe ssh user@server program

Motivation:

This use case is ideal for users who wish to utilize software installed on a remote server but need to interact with it through a graphical user interface (GUI) on their local machine. For instance, a researcher might need to run a resource-intensive simulation program that is installed on a powerful remote server but requires a GUI to monitor results in real time. By using Waypipe, they can execute the program on the remote server while accessing and interacting with the GUI locally.

Explanation:

• waypipe: The command name that initiates the Waypipe utility to enable remote graphical application execution under Wayland.

• ssh: An abbreviation for Secure Shell, this command is used to establish a secure and encrypted connection between the local machine and the remote server.

• user@server: Specifies the credentials required for logging into the server remotely. “user” is the username on the remote machine, and “server” can be an IP address or a hostname of the remote server.

• program: Refers to the specific graphical application that you wish to run on the remote server. This is where you would place the name of the application you intend to execute.

Example Output:

Upon executing the command, the specified ‘program’ starts on the remote server, with its interface displayed on your local machine. This allows direct interaction with the application as if it were running locally, despite consuming remote system resources.

Use case 2: Open an SSH tunnel to run any program remotely and display it locally

Code:

waypipe ssh user@server

Motivation:

This approach is advantageous when you want to open a general-purpose connection to a remote server to run various graphical applications without needing to specify which application at the command’s initiation. This can serve as a flexible, session-based setup where you plan to run different applications over the same SSH connection. For example, during a collaborative coding session, a developer might want to test multiple graphical applications sequentially on a shared remote environment.

Explanation:

• waypipe: Again, this specifies the use of Waypipe to facilitate the graphics forwarding process via Wayland.

• ssh: Utilized here to establish a secure channel or tunnel through which data can flow securely between the local client and remote server.

• user@server: Similar to the previous use case, this indicates the account and location details required to log into the remote machine, with “user” being the username and “server” being the remote machine identifier.

Example Output:

After executing this command, a secure SSH session is initiated, enabling you to remotely execute various graphical programs sequentially. The outputs and interfaces of these applications are displayed on the local machine, allowing an array of graphical operations to be managed remotely.

Conclusion:

Waypipe is an ingenious tool for professionals who require remote access to graphical applications within a Wayland environment, eliminating the spatial constraint of executing such apps locally. By understanding the different command arguments and their purpose, users can effectively navigate and utilize remote computing power while retaining the user-friendly interactions afforded by graphical interfaces.
