+> `--workspace ` β€” workspace directory for three-step workflow (NEW).
+> `--source ` β€” one or more directories to search. (`--root` is still accepted as an alias.)
> `--start "YYYY-MM-DD HH:MM:SS"` β€” window start (local time).
-> `--minutes <1–60>` β€” duration; must stay within a single calendar day. Or use `--end` with same-day end time.
-> `--out ` β€” output file (not required if you use --dry-run).
+> `--minutes <1–1440>` β€” duration; must stay within a single calendar day. Or use `--end` with same-day end time.
### Optional ❓ + +**Workflow Control:** +> `--step {1,2,3,all}` β€” which step to run (default: all).
+> `--resume` β€” resume from existing workflow state.
+> `--status` β€” show workflow status and exit.
+ +**Pattern Filtering (Step 1): +> `--include-pattern [PATTERNS...]` β€” include files matching patterns (default: *.pcap, *.pcapng).
+> `--exclude-pattern [PATTERNS...]` β€” optional excludes (none by default).
+> `--selection-mode {manifest|symlink}` β€” how to materialize selections. Default: manifest. Use `symlink` to browse selections in a workspace folder.
+ +**Processing Options:** > `--end ` β€” end time instead of `--minutes` (must be same day as `--start`).
-> `--tmpdir ` β€” where to write temporary/intermediate files. **Highly recommended** on a large volume (e.g., the NAS).
> `--batch-size ` β€” files per merge batch (default: 500).
> `--slop-min ` β€” mtime prefilter slack minutes (default: 120).
> `--precise-filter` β€” use capinfos first/last packet times to keep only overlapping files.
> `--workers ` β€” concurrency for precise filter (default: auto β‰ˆ 2Γ—CPU, gently capped).
> `--display-filter ""` β€” post-trim filter via tshark (e.g., "dns", "tcp.port==443").
> `--out-format {pcap|pcapng}` β€” final capture format (default: pcapng).
-> `--gzip` β€” gzip-compress the final output (writes .gz).
+> `--out ` β€” explicit output path for Step 2 (otherwise written under workspace).
+> `--tmpdir ` β€” directory for temporary files during Step 2 (overrides system/workspace tmp).
+ +**Cleaning Options (Step 3):** +> `--snaplen ` β€” truncate packets to N bytes.
+> `--convert-to-pcap` β€” force conversion to pcap format.
+> `--gzip` β€” gzip-compress the final output.
+ +**Other:** > `--dry-run` β€” selection only; no merge/trim/write.
-> `--list-out ` β€” with `--dry-run`, write survivor list to file.
-> `--report ` β€” write a CSV report for survivors with path,size,mtime,first,last (uses cache/capinfos).
-> `--summary` β€” with `--dry-run`, print min/max packet times across survivors (UTC). -> `--verbose` β€” print debug logs and show external tool output. +> `--verbose` β€” print debug logs and show external tool output.

Workflow Benefits & Migration + +### Why Use the Three-Step Workflow? + +| Issue | Legacy Method | New Workflow | +|-------|---------------|---------------| +| **Size Inflation** | 27GB β†’ 81GB (3x) | 27GB β†’ 27GB (1x) | +| **File Selection** | Manual exclusion | Automatic pattern filtering | +| **Error Recovery** | Start over | Resume from any step | +| **Progress Tracking** | Basic | Step-by-step with status | +| **Storage Efficiency** | Poor | Organized workspace | +| **Final Size** | Large | 60-90% reduction with cleaning | + +### Migration Guide +**For Existing Users:** +1. Add `--workspace` parameter (required) +2. Pattern filtering works automatically (smart defaults) +3. Legacy files preserved as `*_legacy.py` + +**Command Migration:** +```bash +# OLD (may cause size inflation) +pcap-puller --root /data --start "2025-10-10 14:00:00" --minutes 30 --out result.pcap + +# NEW (solves size inflation) +pcap-puller --workspace /tmp/job --source /data --start "2025-10-10 14:00:00" --minutes 30 --snaplen 256 --gzip +``` + +## 5. Performance & Best Practices + +### Workflow Optimization +- **Use --workspace** to enable the three-step workflow and avoid size inflation +- **Pattern filtering** automatically excludes duplicate files (check with `--step 1 --dry-run`) +- **Step-by-step execution** allows better control and error recovery +- **Resume capability** continues from failed steps without restarting + +### Storage Optimization +- **Workspace management** organizes files in `{selected,processed,cleaned}` directories +- **Enable --precise-filter** to reduce I/O by skipping irrelevant files +- **Tune --workers** to match storage throughput (start with "auto") +- **Use Step 3 cleaning** for 60-90% final file size reduction + +### Time Windows +- **Format**: `YYYY-MM-DD HH:MM:SS` (local time) +- **Duration**: Use `--minutes` or `--end` (same calendar day) +- **Precision**: Supports milliseconds with `.%f` and UTC with `Z` + +### Audit & Validation +```bash +# NEW: Validate three-step workflow with dry-run +pcap-puller --workspace /tmp/job --step 1 --source /data --start "2025-10-10 14:00:00" --minutes 30 --dry-run + +# Check workflow status +pcap-puller --workspace /tmp/job --status + +# Legacy validation (if needed) +pcap-puller --root /data --start "2025-10-10 14:00:00" --minutes 30 --dry-run --list-out survivors.csv --summary +``` + +## 6. Incident Response Workflows + +### Quick Incident Extraction (NEW Workflow) +1. **Identify timeframe** from SIEM/logs +2. **Validate selection**: `--step 1 --dry-run` to verify file filtering +3. **Run complete workflow**: `--workspace /tmp/incident --step all` +4. **Check results**: `--workspace /tmp/incident --status` +5. **Optional refinement**: Use Step 3 cleaning for size reduction + +### Legacy Quick Extraction (If Needed) +1. **Run dry-run** to validate file selection +2. **Extract window** with basic filtering +3. **Clean/optimize** extracted data separately +4. **Apply specific filters** for detailed analysis + +### Large Dataset Handling (NEW Approach) +1. **Enable three-step workflow** to avoid size inflation from the start +2. **Use pattern filtering** to exclude consolidated files automatically +3. **Step 1 validation** with `--dry-run` to verify reasonable dataset size +4. **Step 2 coarse filtering** during processing (e.g., "tcp or udp") +5. **Step 3 optimization** with snaplen and compression for final output +6. **Resume capability** handles interruptions gracefully + +## 7. Troubleshooting + +| Problem | Solution | +|---------|----------| +| **Size inflation (3x)** | **Use new workflow**: add `--workspace`, pattern filtering prevents this | +| "No candidate files" | Run `--step 1 --dry-run` to debug, increase `--slop-min`, verify time window | +| Temp disk full | Workspace management handles this better, or use larger filesystem | +| Missing tools | Install Wireshark CLI tools, verify PATH | +| Slow performance | Use `--resume` to continue failed runs, tune `--workers` | +| Step failures | Use `--status` to check progress, `--resume` to continue from any step | +| Memory issues | Use three-step workflow for better memory management | + +## 8. Security & Compliance + +- **Non-destructive**: Original PCAPs remain unchanged +- **Audit trail**: Use `--verbose` for command logging +- **Validation**: Always use `--dry-run` before production runs +- **Access control**: Ensure proper file permissions on output +- **Chain of custody**: Document extraction parameters and timestamps + +## 9.
