From 2debd073f86083b55202bca39ba19d64e32e1d93 Mon Sep 17 00:00:00 2001 From: Jeongkyu Shin Date: Fri, 19 Dec 2025 16:59:58 +0900 Subject: [PATCH 1/4] fix: Apply SSH config ProxyJump directive when -J option not specified (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. --- docs/architecture/ssh-jump-hosts.md | 66 ++++++++++++++++++-- src/app/dispatcher.rs | 1 + src/app/initialization.rs | 93 +++++++++++++++++++++++++++++ src/commands/exec.rs | 5 +- src/executor/connection_manager.rs | 19 +++++- src/executor/parallel.rs | 18 ++++++ 6 files changed, 195 insertions(+), 7 deletions(-) diff --git a/docs/architecture/ssh-jump-hosts.md b/docs/architecture/ssh-jump-hosts.md index 1310934e..4474a32a 100644 --- a/docs/architecture/ssh-jump-hosts.md +++ b/docs/architecture/ssh-jump-hosts.md @@ -330,6 +330,64 @@ pub fn get_max_jump_hosts -> usize { - No compilation warnings (after clippy allows) - Successfully handles multi-hop scenarios +### SSH Config ProxyJump Integration (Issue #117 - Implemented) + +**Implementation:** `src/executor/connection_manager.rs`, `src/app/initialization.rs` + +The jump host resolution now integrates with SSH configuration files, automatically using `ProxyJump` directives when no CLI `-J` option is specified: + +**Priority Order:** +1. **CLI `-J` option** (highest priority) - Explicitly specified jump hosts +2. **SSH config `ProxyJump` directive** - Per-host configuration from `~/.ssh/config` +3. **None** - Direct connection (no jump host) + +**Implementation Details:** +```rust +// In connection_manager.rs execute_on_node_with_jump_hosts() +let ssh_config_jump_hosts = config + .ssh_config + .and_then(|ssh_config| ssh_config.get_proxy_jump(&node.host)); + +let effective_jump_hosts = if config.jump_hosts.is_some() { + config.jump_hosts // CLI takes precedence +} else { + ssh_config_jump_hosts.as_deref() // Fall back to SSH config +}; +``` + +**Example SSH Config:** +``` +Host *.internal + ProxyJump bastion.example.com + +Host db.internal + ProxyJump db-gateway.example.com +``` + +**Usage:** +```bash +# Automatically uses bastion.example.com from SSH config +bssh -H web.internal "uptime" + +# CLI option overrides SSH config +bssh -J custom-jump.example.com -H web.internal "uptime" + +# Most specific SSH config pattern wins +bssh -H db.internal "uptime" # Uses db-gateway.example.com +``` + +**Benefits:** +- Seamless integration with existing SSH workflows +- Centralized jump host configuration +- Per-host or wildcard pattern support +- No need to specify `-J` for frequently accessed internal hosts + +**Tests:** +- Added unit tests in `src/app/initialization.rs::tests` +- Tests verify CLI precedence over SSH config +- Tests verify wildcard pattern matching +- Tests verify fallback behavior + ### Known Limitations **Connection Pooling:** @@ -337,14 +395,14 @@ pub fn get_max_jump_hosts -> usize { - Each operation establishes fresh tunnel - **Rationale:** russh session limitations prevent connection reuse -**Configuration File Support:** -- Jump hosts only supported via CLI `-J` flag currently -- Configuration file support for per-cluster jump hosts is not implemented +**YAML Configuration File Support:** +- Jump hosts via YAML cluster config not yet implemented +- Only CLI `-J` and SSH config `ProxyJump` are supported - **Future Enhancement:** Add `jump_hosts` field to cluster configuration ### Future Enhancements -1. **Configuration File Support:** +1. **YAML Configuration File Support:** ```yaml clusters: production: diff --git a/src/app/dispatcher.rs b/src/app/dispatcher.rs index 2a6a349f..278ad847 100644 --- a/src/app/dispatcher.rs +++ b/src/app/dispatcher.rs @@ -407,6 +407,7 @@ async fn handle_exec_command(cli: &Cli, ctx: &AppContext, command: &str) -> Resu sudo_password, batch: cli.batch, fail_fast: cli.fail_fast, + ssh_config: Some(&ctx.ssh_config), }; execute_command(params).await } diff --git a/src/app/initialization.rs b/src/app/initialization.rs index 9998c682..e8b006de 100644 --- a/src/app/initialization.rs +++ b/src/app/initialization.rs @@ -345,3 +345,96 @@ pub fn determine_use_keychain(ssh_config: &SshConfig, hostname: Option<&str>) -> pub fn determine_use_keychain(_ssh_config: &SshConfig, _hostname: Option<&str>) -> bool { false } + +/// Determine the effective jump hosts for a connection. +/// +/// Priority order: +/// 1.
