…d (issue #117) The get_proxy_jump() function existed but was never called during connection. Now bssh automatically uses ProxyJump from ~/.ssh/config when connecting to hosts that have it configured. Priority order for jump host resolution: 1. CLI -J option (highest priority) 2. SSH config ProxyJump directive 3. None (direct connection) Changes: - Add ssh_config field to ExecutionConfig and ParallelExecutor - Update execute_on_node_with_jump_hosts to resolve effective jump hosts - Pass ssh_config through dispatcher to execution commands - Add determine_effective_jump_hosts helper function - Add comprehensive unit tests for jump host resolution - Update documentation in docs/architecture/ssh-jump-hosts.md The implementation resolves jump hosts per-node, allowing different nodes to use different jump hosts based on their SSH config patterns.

This commit extends the SSH config ProxyJump integration to file transfer operations (upload/download), addressing the consistency issue where command execution respected SSH config ProxyJump but file transfers did not. Changes: - Add ssh_config parameter to upload_to_node, download_from_node, and download_dir_from_node functions in connection_manager.rs - Apply the same jump host resolution logic (CLI precedence over SSH config) for all file transfer operations - Update execution_strategy.rs task functions to accept ssh_config - Update parallel.rs to pass ssh_config to file transfer tasks This ensures consistent behavior where users configuring ProxyJump in their ~/.ssh/config will have it applied to both command execution and file transfers automatically.
Completes the SSH config ProxyJump integration for the upload and download CLI commands by adding ssh_config to FileTransferParams. Changes: - Add ssh_config field to FileTransferParams struct in upload.rs - Update dispatcher.rs to pass ctx.ssh_config in FileTransferParams for both upload and download commands - Update upload_file() to call executor.with_ssh_config() - Update download_file() to call executor.with_ssh_config() - Update download_dir_from_node() call to pass params.ssh_config This ensures that `bssh upload` and `bssh download` commands now properly respect ProxyJump directives from ~/.ssh/config.

Adds 11 new unit tests for the SSH config ProxyJump resolution logic in connection_manager.rs: Test Coverage: - CLI jump hosts precedence over SSH config - SSH config ProxyJump fallback when CLI not specified - No jump hosts when neither CLI nor SSH config specifies one - No jump hosts when SSH config is not provided - Multi-hop ProxyJump chains (comma-separated) - ProxyJump with port specification (host:port) - ProxyJump with user and port (user@host:port) - Wildcard pattern matching (*.internal.example.com) - Unmatched hosts returning no ProxyJump - ProxyJump "none" value for disabling jump - Complex multi-hop chains with mixed formats Also adds a `resolve_effective_jump_hosts` helper function that encapsulates the priority logic for easier testing.

Summary
Fixes #117
The
get_proxy_jump()function existed in the SSH config parser but was never called during connection establishment. This PR implements automatic ProxyJump directive resolution from~/.ssh/configwhen the CLI-Joption is not specified.Changes
Core Implementation
src/executor/connection_manager.rs: Updatedexecute_on_node_with_jump_hosts()to resolve effective jump hosts by checking CLI option first, then falling back to SSH config ProxyJumpsrc/executor/parallel.rs: Addedssh_configfield toParallelExecutorand updated all constructorssrc/commands/exec.rs: Addedssh_configfield toExecuteCommandParamsand passed it to the executorsrc/app/dispatcher.rs: Updated to pass SSH config through to execution commandssrc/app/initialization.rs: Addeddetermine_effective_jump_hosts()helper function with comprehensive unit testsDocumentation
docs/architecture/ssh-jump-hosts.md: Added new section documenting SSH config ProxyJump integration with examples and usage patternsPriority Order
Jump host resolution now follows this priority:
-Joption (highest priority) - Explicitly specified jump hostsProxyJumpdirective - Per-host configuration from~/.ssh/configExample Usage
Given this SSH config:
Now works automatically:
