# smartdns - Implementation Hints
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
The smartdns library is structured into three main modules:
|
||||
|
||||
1. **Client Module** (`ts_client/`) - DNS client functionality
|
||||
2. **Server Module** (`ts_server/`) - DNS server implementation
|
||||
3. **Main Module** (`ts/`) - Re-exports both client and server
|
||||
|
||||
## Client Module (Smartdns class)
|
||||
|
||||
### Key Features:
|
||||
- DNS record queries (A, AAAA, TXT, MX, etc.)
|
||||
- Support for multiple DNS providers (Google DNS, Cloudflare)
|
||||
- DNS propagation checking with retry logic
|
||||
- DNSSEC verification support
|
||||
- Both HTTP-based (DoH) and Node.js DNS resolver fallback
|
||||
|
||||
### Implementation Details:
|
||||
- Uses Cloudflare's DNS-over-HTTPS API as primary resolver
|
||||
- Falls back to Node.js DNS module for local resolution
|
||||
- Implements automatic retry logic with configurable intervals
|
||||
- Properly handles quoted TXT records and trailing dots in domain names
|
||||
|
||||
### Key Methods:
|
||||
- `getRecordsA()`, `getRecordsAAAA()`, `getRecordsTxt()` - Type-specific queries
|
||||
- `getRecords()` - Generic record query with retry support
|
||||
- `checkUntilAvailable()` - DNS propagation verification
|
||||
- `getNameServers()` - NS record lookup
|
||||
- `makeNodeProcessUseDnsProvider()` - Configure system DNS resolver
|
||||
|
||||
## Server Module (DnsServer class)
|
||||
|
||||
### Key Features:
|
||||
- Full DNS server supporting UDP and HTTPS (DoH) protocols
|
||||
- DNSSEC implementation with multiple algorithms
|
||||
- Dynamic handler registration for custom responses
|
||||
- Let's Encrypt integration for automatic SSL certificates
|
||||
- Wildcard domain support with pattern matching
|
||||
|
||||
### DNSSEC Implementation:
|
||||
- Supports ECDSA (algorithm 13), ED25519 (algorithm 15), and RSA (algorithm 8)
|
||||
- Automatic DNSKEY and DS record generation
|
||||
- RRSIG signature generation for authenticated responses
|
||||
- Key tag computation following RFC 4034
|
||||
|
||||
### Let's Encrypt Integration:
|
||||
- Automatic SSL certificate retrieval using DNS-01 challenges
|
||||
- Dynamic TXT record handler registration for ACME validation
|
||||
- Certificate renewal and HTTPS server restart capability
|
||||
- Domain authorization filtering for security
|
||||
|
||||
### Handler System:
|
||||
- Pattern-based domain matching using minimatch
|
||||
- Support for all common record types
|
||||
- **Multiple Handler Support**: As of v7.4.2+, multiple handlers can contribute records of the same type
|
||||
- Handler chaining for complex scenarios
|
||||
- Automatic SOA response for unhandled queries
|
||||
|
||||
### Multiple Records Support (v7.4.2+):
|
||||
- Server now processes ALL matching handlers for a query (previously stopped after first match)
|
||||
- Enables proper multi-NS record support for domain registration
|
||||
- Supports round-robin DNS with multiple A/AAAA records
|
||||
- Allows multiple TXT records (SPF, DKIM, domain verification)
|
||||
- Each handler contributes its record to the response
|
||||
|
||||
## Key Dependencies
|
||||
|
||||
- `dns-packet`: DNS packet encoding/decoding (wire format)
|
||||
- `elliptic`: Cryptographic operations for DNSSEC
|
||||
- `acme-client`: Let's Encrypt certificate automation
|
||||
- `minimatch`: Glob pattern matching for domains
|
||||
- `@push.rocks/smartrequest`: HTTP client for DoH queries
|
||||
- `@tsclass/tsclass`: Type definitions for DNS records
|
||||
|
||||
## Testing Insights
|
||||
|
||||
The test suite demonstrates:
|
||||
- Mock ACME client for testing Let's Encrypt integration
|
||||
- Self-signed certificate generation for HTTPS testing
|
||||
- Unique port allocation to avoid conflicts
|
||||
- Proper server cleanup between tests
|
||||
- Both UDP and HTTPS query validation
|
||||
|
||||
## Common Patterns
|
||||
|
||||
1. **DNS Record Types**: Internally mapped to numeric values (A=1, AAAA=28, etc.)
|
||||
2. **Error Handling**: Graceful fallback and retry mechanisms
|
||||
3. **DNSSEC Workflow**: Zone → Key Generation → Signing → Verification
|
||||
4. **Certificate Flow**: Domain validation → Challenge setup → Verification → Certificate retrieval
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- Client implements caching via DNS-over-HTTPS responses
|
||||
- Server can handle concurrent UDP and HTTPS requests
|
||||
- DNSSEC signing is performed on-demand for efficiency
|
||||
- Handler registration is O(n) lookup but uses pattern caching
|
||||
|
||||
## Security Notes
|
||||
|
||||
- DNSSEC provides authentication but not encryption
|
||||
- DoH (DNS-over-HTTPS) provides both privacy and integrity
|
||||
- Let's Encrypt integration requires proper domain authorization
|
||||
- Handler patterns should be carefully designed to avoid open resolvers
|
||||
|
||||
## Known Issues
|
||||
|
||||
1. **DNSSEC RRSIG Generation**: When multiple records of the same type are returned, DNSSEC signing may encounter issues with the current implementation
|
||||
2. **SOA Record Prefix**: The server hardcodes 'ns1.' prefix for SOA mname field which may not match actual nameserver names
|
||||
3. **Handler Deduplication**: If the same handler is registered multiple times, it will contribute duplicate records

# SmartDNS Improvement Plan
|
||||
|
||||
Command to reread CLAUDE.md: `cat /home/philkunz/.claude/CLAUDE.md`
|
||||
|
||||
## Critical Issue: Support Multiple DNS Records of Same Type
|
||||
|
||||
### Current Status: Planning
|
||||
**Priority: HIGH** - This issue blocks proper DNS server operation and domain registration
|
||||
|
||||
### Problem Summary
|
||||
The DNS server currently exits after finding the first matching handler for a query, preventing it from serving multiple records of the same type (e.g., multiple NS records, multiple A records for round-robin, multiple TXT records).
|
||||
|
||||
### Implementation Plan
|
||||
|
||||
#### Phase 1: Analysis and Testing ✅ COMPLETED
|
||||
- [x] Create comprehensive test cases demonstrating the issue
|
||||
- [x] Test with multiple NS records scenario
|
||||
- [x] Test with multiple A records (round-robin) scenario
|
||||
- [x] Test with multiple TXT records scenario
|
||||
- [x] Document current behavior vs expected behavior
|
||||
|
||||
#### Phase 2: Core Fix Implementation ✅ COMPLETED
|
||||
- [x] Remove the `break` statement in `processDnsRequest` method (line 609)
|
||||
- [x] Ensure all matching handlers are processed
|
||||
- [x] Accumulate all answers from matching handlers
|
||||
- [x] Add NS record serialization for DNSSEC support
|
||||
|
||||
#### Phase 3: Handler Interface Enhancement (Optional)
|
||||
- [ ] Consider allowing handlers to return arrays of records
|
||||
- [ ] Update `IDnsHandler` interface to support `DnsAnswer | DnsAnswer[] | null`
|
||||
- [ ] Update processing logic to handle array responses
|
||||
- [ ] Maintain backward compatibility with existing handlers
|
||||
|
||||
#### Phase 4: Testing and Validation
|
||||
- [ ] Test multiple NS records return correctly
|
||||
- [ ] Test round-robin DNS with multiple A records
|
||||
- [ ] Test multiple TXT records (SPF + DKIM + verification)
|
||||
- [ ] Test DNSSEC signatures for multiple records
|
||||
- [ ] Verify no regression in single-record scenarios
|
||||
|
||||
#### Phase 5: Documentation and Examples
|
||||
- [ ] Update documentation with multiple record examples
|
||||
- [ ] Add example for registering multiple NS records
|
||||
- [ ] Add example for round-robin DNS setup
|
||||
- [ ] Document best practices for handler registration
|
||||
|
||||
### Technical Details
|
||||
|
||||
#### Current Code Issue (ts_server/classes.dnsserver.ts:609)
|
||||
```typescript
|
||||
answered = true;
|
||||
break; // <-- This prevents multiple handlers from contributing answers
|
||||
```
|
||||
|
||||
#### Proposed Fix
|
||||
```typescript
|
||||
answered = true;
|
||||
// Continue processing other handlers instead of breaking
|
||||
```
|
||||
|
||||
### Success Criteria
|
||||
- DNS queries return ALL matching records from ALL matching handlers
|
||||
- Domain registration with multiple NS records succeeds
|
||||
- Round-robin DNS works with multiple A records
|
||||
- Multiple TXT records can be served for the same domain
|
||||
- DNSSEC signatures are properly generated for all returned records
|
||||
|
||||
### Implementation Summary
|
||||
|
||||
#### What Was Fixed
|
||||
1. **Core Issue Resolved**: Removed the `break` statement at line 609 in `processDnsRequest` that was preventing multiple handlers from contributing DNS answers
|
||||
2. **NS Record Serialization**: Added NS record type support in `serializeRData` method for DNSSEC compatibility
|
||||
3. **Result**: DNS server now correctly returns multiple records of the same type from different handlers
|
||||
|
||||
#### Test Results
|
||||
- ✅ Multiple NS records now work (2+ nameservers returned)
|
||||
- ✅ Round-robin DNS with multiple A records works
|
||||
- ✅ Multiple TXT records (SPF, DKIM, verification) work
|
||||
- ⚠️ DNSSEC RRSIG generation needs additional fixes for multiple record scenarios
|
||||
|
||||
#### Code Changes
|
||||
```typescript
|
||||
// Before (line 609):
|
||||
answered = true;
|
||||
break; // This was preventing multiple handlers from running
|
||||
|
||||
// After:
|
||||
answered = true;
|
||||
// Continue processing other handlers to allow multiple records
|
||||
```
|
||||
|
||||
### Additional Improvements to Consider
|
||||
1. Fix DNSSEC RRSIG generation for multiple records
|
||||
2. Fix SOA record timeout issues
|
||||
3. Make DNSSEC zone prefix configurable (remove hardcoded 'ns1.')
|
||||
4. Improve error handling for edge cases
|
||||
5. Consider handler interface enhancement to return arrays
