python3 main.py -c /path/to/config.json # Use a different config file
python3 main.py --install-cert # Install MITM CA certificate and exit
python3 main.py --no-cert-check # Skip automatic CA install check on startup
python3 main.py --scan # Scan Google IPs and find the fastest one
```
> **Auto-install:** On startup (MITM mode), the proxy automatically checks if the CA certificate is trusted and attempts to install it. Use `--no-cert-check` to skip this. If auto-install fails (e.g. needs elevation), run `python main.py --install-cert` manually or follow Step 6 above.
### Scanning for the Fastest Google IP
If your current `google_ip` in `config.json` is blocked or slow, you can scan to find a faster one:
```bash
python3 main.py --scan
```
This will:
1. Probe 27 candidate Google IPs in parallel
2. Measure latency from your network
3. Display results in a table
4. Recommend the fastest IP
5. Exit with exit code 0 if at least one IP is reachable, 1 otherwise
**Example output:**
```
Scanning 27 Google frontend IPs
SNI: www.google.com
Timeout: 4s per IP
Concurrency: 8 parallel probes
IP LATENCY STATUS
-------------------- ------------ -------------------------
216.239.32.120 42ms OK
216.239.34.120 45ms OK
216.239.36.120 52ms OK
142.250.80.142 timeout timeout
...
Result: 15 / 27 reachable
Top 3 fastest IPs:
1. 216.239.32.120 (42ms)
2. 216.239.34.120 (45ms)
3. 216.239.36.120 (52ms)
Recommended: Set "google_ip": "216.239.32.120" in config.json
```
After scanning, update your `config.json` with the recommended IP and restart the proxy.

```
> **نصب خودکار:** هنگام اجرا در حالت `apps_script`، برنامه به‌طور خودکار بررسی می‌کند که آیا گواهی CA قابل اعتماد است یا نه و در صورت نیاز آن را نصب می‌کند. اگر نصب خودکار ناموفق بود (مثلاً نیاز به دسترسی مدیر دارد)، می‌توانید دستور `python main.py --install-cert` را اجرا کنید یا مراحل مرحله ۶ را دنبال کنید.
### اسکن کردن برای یافتن سریع‌ترین IP گوگل
اگر `google_ip` فعلی در `config.json` بلاک شده یا آهسته است، می‌توانید اسکن کنید تا سریع‌ترین آن را پیدا کنید:
```bash
python3 main.py --scan
```
این دستور:
1. ۲۷ IP برای fronting Google را به‌صورت موازی بررسی می‌کند
2. تأخیر (latency) از شبکه شما را اندازه می‌گیرد
3. نتایج را در جدول نمایش می‌دهد
4. سریع‌ترین IP را پیشنهاد می‌دهد
5. اگر حداقل یک IP در دسترس باشد کد خروج ۰، ورنه ۱ را برمی‌گرداند
**نمونه خروجی:**
```

3. 216.239.36.120 (52ms)
Recommended: Set "google_ip": "216.239.32.120" in config.json
```
پس از اسکن، مقدار `google_ip` در `config.json` را با IP پیشنهادی به‌روزرسانی کنید و پراکسی را دوباره راه‌اندازی کنید.
