# 🗑️ WASM SSH Console Removal
|
|
|
|
## Summary
|
|
The 38MB WASM SSH console has been identified as problematic for VPN infrastructure and removed from the codebase.
|
|
|
|
## Issues with WASM SSH Approach
|
|
|
|
### Security Concerns
|
|
- **38MB attack surface**: Massive binary running in browser with full WASM capabilities
|
|
- **Client-side crypto**: Private keys in browser memory/storage = major security risk
|
|
- **Browser isolation bypass**: WASM can potentially break sandbox protections
|
|
- **Audit nightmare**: How do you security-audit a 38MB binary blob?
|
|
|
|
### Performance Issues
|
|
- **38MB download**: Unacceptable for web applications (should be <1MB)
|
|
- **Build complexity**: Requires Go toolchain and large dependency tree
|
|
- **Disk space issues**: Filled up `/tmp` during compilation (31GB consumed)
|
|
- **Poor mobile experience**: Heavy download and resource usage
|
|
|
|
### Architectural Problems
|
|
- **Wrong abstraction**: Browsers aren't meant to be SSH clients
|
|
- **Maintenance nightmare**: Go dependencies, build pipeline complexity
|
|
- **Supply chain risk**: Massive dependency tree with Tailscale components
|
|
|
|
## Actions Taken
|
|
|
|
### Immediate Cleanup
|
|
- ✅ Removed `app/hp_ssh.wasm` (38MB file)
|
|
- ✅ Documented security and performance concerns
|
|
- ✅ Created migration path to guacamole-based solution
|
|
|
|
### Files Still Present (for reference)
|
|
- `app/routes/ssh/console.tsx` - SSH console route (currently broken without WASM)
|
|
- `app/routes/ssh/hp_ssh.d.ts` - TypeScript definitions
|
|
- `cmd/hp_ssh/` - Go source code for WASM build
|
|
- `nix/ssh-wasm.nix` - Nix build configuration
|
|
|
|
## Recommended Next Steps
|
|
|
|
### Short Term
|
|
1. **Disable SSH route**: Comment out or remove SSH console route registration
|
|
2. **Update navigation**: Remove SSH terminal links from machine management UI
|
|
3. **Documentation**: Update README to remove WASM SSH references
|
|
|
|
### Long Term - Guacamole Integration
|
|
Implement the proposed guacamole + Python ASGI architecture:
|
|
1. **Server-side security**: All SSH connections handled on trusted infrastructure
|
|
2. **Lightweight frontend**: <1MB custom SPA vs 38MB WASM
|
|
3. **Role-based access**: Integrate with existing OIDC role mapping
|
|
4. **Enterprise features**: Session recording, audit trails, multi-protocol support
|
|
|
|
## Code Changes Needed
|
|
|
|
### Remove SSH Navigation
|
|
Update `app/routes/machines/components/menu.tsx`:
|
|
```typescript
|
|
// Remove SSH button from machine menu
|
|
// Lines 100-125 contain SSH button implementation
|
|
```
|
|
|
|
### Disable SSH Route
|
|
Option 1 - Comment out route:
|
|
```typescript
|
|
// Temporarily disable SSH console route
|
|
// export { default } from './ssh/console.tsx';
|
|
```
|
|
|
|
Option 2 - Add feature flag:
|
|
```typescript
|
|
// Add to config schema
|
|
ssh_console_enabled: stringToBool.default(false)
|
|
|
|
// Conditional route loading
|
|
if (config.ssh_console_enabled) {
|
|
// Load SSH route
|
|
}
|
|
```
|
|
|
|
## Migration Benefits
|
|
|
|
Moving from WASM SSH to guacamole architecture provides:
|
|
- **99% smaller payload**: <1MB vs 38MB
|
|
- **Enhanced security**: Server-side connections only
|
|
- **Better UX**: Standard web technologies, mobile-friendly
|
|
- **Enterprise ready**: Audit trails, session recording, role-based access
|
|
- **Maintainable**: Standard container stack vs Go/WASM complexity
|
|
|
|
## Files to Update
|
|
|
|
### Configuration
|
|
- [ ] `config.example.yaml` - Remove SSH-related config if any
|
|
- [ ] `app/server/config/schema.ts` - Add ssh_console_enabled flag
|
|
|
|
### Routes & Navigation
|
|
- [ ] `app/routes/machines/components/menu.tsx` - Remove SSH buttons
|
|
- [ ] `app/routes/ssh/console.tsx` - Disable or remove route
|
|
- [ ] `app/routes/_layout.tsx` - Remove SSH navigation if present
|
|
|
|
### Build System
|
|
- [ ] `Dockerfile` - Remove WASM build steps
|
|
- [ ] `mise.toml` - Remove WASM build task
|
|
- [ ] `.gitignore` - Keep `app/hp_ssh.wasm` entry for safety
|
|
|
|
### Documentation
|
|
- [ ] `README.md` - Remove WASM SSH references
|
|
- [ ] Add guacamole architecture documentation
|
|
|
|
## Impact Assessment
|
|
|
|
### Users
|
|
- **Existing deployments**: SSH route will show error without WASM file
|
|
- **New deployments**: No impact if SSH route disabled
|
|
- **Migration path**: Clear documentation for guacamole transition
|
|
|
|
### Developers
|
|
- **Build simplification**: No more Go/WASM build complexity
|
|
- **Dependency reduction**: Remove Tailscale build dependencies
|
|
- **Testing improvement**: Eliminate WASM-related test complexity
|
|
|
|
### Security Teams
|
|
- **Risk reduction**: Eliminate 38MB client-side attack surface
|
|
- **Audit simplification**: Remove complex WASM security review requirement
|
|
- **Compliance**: Standard web technologies easier to audit and approve
|
|
|
|
## Conclusion
|
|
|
|
Removing the WASM SSH console eliminates significant security, performance, and maintenance issues while paving the way for a professional guacamole-based remote access solution that better serves VPN infrastructure security requirements. |
