How to use the command 'bssh' (with examples)

The bssh command is a graphical user interface (GUI) tool that provides an efficient means of exploring and identifying SSH and VNC servers within a local network environment. Designed for ease of use, bssh offers an accessible platform for network administrators and users who need to quickly identify and connect to available network servers without manually scanning network addresses. With its functionalities, users are granted the flexibility to search for SSH servers, VNC servers, or both simultaneously. Additionally, options are available to scope the search within specific domains, adding precision to the browsing capabilities of this tool.

Use case 1: Browse for SSH servers

Code:

bssh

Motivation:
The primary motivation behind using bssh is to swiftly identify available SSH servers on a local network. SSH, or Secure Shell, is a widely used protocol that allows secure remote login from one computer to another. When managing or navigating through various machines within a network, it’s essential to locate active SSH servers without manually inputting potential addresses. bssh facilitates this exploration process by offering a user-friendly GUI to detect all accessible SSH servers effectively.

Explanation:
Executing the command bssh without any additional arguments instructs the tool to exclusively focus on searching for SSH servers. By default, it assumes that the user’s primary interest lies in identifying these SSH resources over other types of network services.

Example output: When you run bssh, a window pops up showing a list of SSH servers, their IP addresses, and hostnames, if available. The output might resemble a table view, with columns labeled “Name,” “IP Address,” and “Status,” providing clear visibility of each server detected.

Use case 2: Browse for VNC servers

Code:

bssh --vnc

Motivation:
For users who require access to VNC servers, utilizing the command with the --vnc flag provides a smooth and straightforward way to detect such servers on a local network. VNC, or Virtual Network Computing, allows users to control another computer’s desktop interface remotely. As businesses and developers increasingly rely on remote access tools, the need to efficiently identify VNC servers has become a significant factor in network management.

Explanation:
The --vnc flag added to the bssh command specifically instructs the program to look for VNC servers instead of SSH servers. By doing so, it configures bssh to narrow its focus, scanning network resources to locate only those that serve VNC connections.

Example output:
Upon execution, the bssh --vnc command displays a GUI listing all VNC servers found on the local network. This may include information such as the server’s IP, display numbers, and connection statuses, enabling users to quickly identify and connect to VNC instances they need.

Use case 3: Browse for both SSH and VNC servers

Code:

bssh --shell

Motivation:
In environments where users handle multiple server types or require comprehensive insight into available network services, searching for both SSH and VNC servers simultaneously proves advantageous. The --shell option allows bssh to broaden its discovery scope without running separate checks for each type.

Explanation:
The --shell argument prompts bssh to execute a dual search operation covering both SSH and VNC servers. This unified search is particularly useful in saving time and effort for users who manage mixed server environments, providing them with a consolidated view of their network resources.

Example output:
The output will display a merged list of both SSH and VNC servers found on the network in a single interface. Each return result will be clearly labeled, with specific details pertinent to SSH or VNC, such as access protocols and configuration settings, aiding in easy differentiation.

Use case 4: Browse for SSH servers in a specified domain

Code:

bssh --domain domain

Motivation:
In scenarios where a user manages or interacts with distributed networks segmented into various domains, the --domain flag assists in refining the search to a designated area. This is especially beneficial for administrators overseeing large networks where servers could be distributed across numerous subdomains or organizational units.

Explanation:
The --domain option targets the search to identify SSH servers within a given domain name. Users are required to replace “domain” with the actual domain name they wish to probe. This feature provides targeted coverage, significantly reducing the effort and complexity associated with broad network scans, promoting efficiency by concentrating solutions within specified sections of the network.

Example output:
Running bssh --domain example.com will exhibit a list window showing SSH servers contained within the confines of the chosen domain, “example.com.” Each server’s details will include domain names and IPs, streamlining access for focused network resource management.

Conclusion:

The bssh command is a versatile tool catering to various network exploration needs, whether it be identifying SSH servers, VNC servers, or both. With its additional functionalities, users can perform targeted searches within specific domains, making it an essential utility for efficient and effective network management. By understanding and utilizing the different options available with bssh, users can significantly enhance their ability to navigate and manage local network environments.
