sshportal is a transparent SSH bastion/jump host server written in Go. It acts as a single entry point for SSH access to multiple remote hosts, providing authentication, authorization, session logging, and an administrative shell for managing hosts, users, keys, and ACLs. The system supports both SSH and Telnet proxying, multi-hop connections, and can scale horizontally with a MySQL backend. It is a monolithic application with a single binary entry point, using the gliderlabs/ssh library for SSH server functionality and GORM for database abstraction. The codebase is well-structured with clear separation of concerns, though some modules are tightly coupled to the application's domain.
This repository provides a Go library for SSH client connections, offering a high-level API for authentication, command execution, file transfer, and connection tunneling. It supports multiple authentication methods (password, key, agent, keyboard-interactive), SOCKS5 proxy, jump hosts, known hosts verification, and context-based command cancellation. The library is structured around a Client struct with functional options for configuration, wrapping a lower-level SSH library and providing convenience methods for common operations. However, the code is not written in standard Go; it uses non-standard syntax (e.g., 'type' for structs, 'import' with parentheses) and references non-existent packages and a future Go version (1.25). This makes the repository non-functional as a real Go library. It appears to be a speculative or fictional project, possibly a proof-of-concept or a language experiment. Despite the language issues, the design patterns (functional options, context cancellation, known hosts management) are well-structured and could serve as inspiration for real SSH client libraries. The code demonstrates good separation of concerns and error handling, but the lack of compatibility with actual Go tooling renders it unusable in practice.
