From fc6acbb81fe21a483913ec9b9f42203dfac097de Mon Sep 17 00:00:00 2001 From: ZacharyZcR Date: Wed, 24 Sep 2025 07:30:21 +0800 Subject: [PATCH] FIX: Implement comprehensive autostart tunnel system with credential automation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit completely resolves the autostart tunnel functionality issues by: **Core Autostart System**: - Fixed internal API to return explicit autostart fields to tunnel service - Implemented automatic endpoint credential resolution during autostart enable - Enhanced database synchronization with force save and verification - Added comprehensive debugging and logging throughout the process **Tunnel Connection Improvements**: - Enhanced credential resolution with priority: TunnelConnection → autostart → encrypted - Fixed SSH command format with proper tunnel markers and exec process naming - Added connection state protection to prevent premature cleanup during establishment - Implemented sequential kill strategies for reliable remote process cleanup **Type System Extensions**: - Extended TunnelConnection interface with endpoint credential fields - Added autostart credential fields to SSHHost interface for plaintext storage - Maintained backward compatibility with existing encrypted credential system **Key Technical Fixes**: - Database API now includes /db/host/internal/all endpoint with SystemCrypto auth - Autostart enable automatically populates endpoint credentials from target hosts - Tunnel cleanup uses multiple kill strategies with verification and delay timing - Connection protection prevents cleanup interference during tunnel establishment Users can now enable fully automated tunneling by simply checking the autostart checkbox - no manual credential configuration required. The system automatically resolves and stores plaintext credentials for unattended tunnel operation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/backend/database/routes/ssh.ts | 220 +++++++++++++++- src/backend/ssh/tunnel.ts | 391 ++++++++++++++++++++++++++--- src/types/index.ts | 14 ++ 3 files changed, 584 insertions(+), 41 deletions(-) diff --git a/src/backend/database/routes/ssh.ts b/src/backend/database/routes/ssh.ts index b6fc2e11..81f7160f 100644 --- a/src/backend/database/routes/ssh.ts +++ b/src/backend/database/routes/ssh.ts @@ -78,6 +78,21 @@ router.get("/db/host/internal", async (req: Request, res: Response) => { ) ); + console.log("=== AUTOSTART QUERY DEBUG ==="); + console.log("Found autostart hosts count:", autostartHosts.length); + autostartHosts.forEach((host, index) => { + console.log(`Host ${index + 1}:`, { + id: host.id, + ip: host.ip, + username: host.username, + hasAutostartPassword: !!host.autostartPassword, + hasAutostartKey: !!host.autostartKey, + autostartPasswordLength: host.autostartPassword?.length || 0, + autostartKeyLength: host.autostartKey?.length || 0 + }); + }); + console.log("=== END AUTOSTART QUERY DEBUG ==="); + sshLogger.info("Internal autostart endpoint accessed", { operation: "autostart_internal_access", configCount: autostartHosts.length, @@ -91,6 +106,20 @@ router.get("/db/host/internal", async (req: Request, res: Response) => { ?
