SSHD Proxy for Private Network Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and accessing software deployed on private networks is challenging due to the lack of exposed endpoints, making it difficult for administrators to communicate and manage applications hosted on third-party cloud services, especially when IP addresses overlap, preventing secure communication and management.
Innovation Solution
Deploying a compute pod configured to execute a secure shell daemon (SSHD) network proxy within the private cluster, allowing authorized administrators to establish an SSH tunnel for secure communication and data transfer, bypassing the need for direct internet access and resolving IP address conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a private network cluster is deployed on third-party cloud services, then computing resources can be accessed remotely, but administrators cannot directly communicate with the cluster due to lack of exposed endpoints and IP address overlaps
Solution Approach 1:
The patent introduces an intermediary compute pod deployed within the private network cluster that provides an SSHD network proxy. This intermediary component enables administrators to access the private network through a gateway that forwards connections, resolving the communication barrier caused by lack of exposed endpoints and IP address overlaps.
Solution Approach 2:
The patent segments the network access by creating a dedicated compute pod with SSHD proxy functionality separate from the main application workloads. This segmentation allows the proxy to handle administrative access independently, enabling secure communication without exposing the entire private network cluster.
2Reliability
If compute instances are deployed in a private network, then secure isolated environment is created, but management and maintenance tasks become difficult due to inaccessible endpoints
Solution Approach 1:
The SSHD network proxy acts as an intermediary that maintains the secure isolated environment while providing a controlled access point for management and maintenance tasks. The proxy authenticates and authorizes administrative connections without compromising the private network's security isolation.
Solution Approach 2:
The compute pod running SSHD serves multiple functions: it provides network proxy capabilities for administrative access, maintains security boundaries, and enables various management operations (SSH connections, port forwarding, tunneling) through a single unified component.
3Reliability
If SSH tunnel is established through compute pod, then secure encrypted communication is enabled, but additional infrastructure complexity is introduced
Solution Approach 1:
The SSHD network proxy simplifies the infrastructure complexity by centralizing the SSH tunneling functionality in a single compute pod. Rather than requiring complex network configurations across multiple nodes, the proxy handles all encryption, authentication, and connection routing through one standardized component.
Solution Approach 2:
The SSHD proxy implements self-service by automatically handling connection requests, authentication, and tunnel establishment without requiring manual configuration of each compute instance. The proxy manages its own state and routing decisions, reducing the operational burden on administrators.

AI summary
Systems and methods for remote management of software on private networks are generally described. In various examples, a cluster of compute instances are deployed by a cloud compute service provider. A first compute pod may be deployed among the cluster of compute instances. The first compute pod may be configured to execute a secure shell daemon (SSHD) network proxy. The first compute pod may be configured to open ports to allow access to the cluster of compute instances by an authorized administrative user. In some examples, a connection may be established between a first computing device executing a secure shell (SSH) process and the SSHD network proxy of the first compute pod. Data may be sent from the first computing device to at least one compute instance of the cluster of compute instances using the connection.
