title: v2Ray on Linux - Testing
description: 
---

We recommend you run v2Ray manually the first time, so you can easily monitor for errors:

```
~/Downloads
❯ /usr/bin/v2ray/v2ray -test -config /etc/v2ray/config.json
```

You'll need to configure your web browser to use the SOCKS proxy at 127.0.0.1 port 1080. (This is easiest with Firefox.)

Then use the browser to open [12vpx.com/ip](https://12vpx.com/ip) to see if you're using the VPN succesfully.

Hit CTRL+C to stop v2Ray when done.
