any software to test proxies as the "proxy hunter" on windows platform?
 

There are some limits on my internet service.
So I often need some proxy servers to visit some website or other internet resources.

On windows platform, I use a software named "proxy hunter" to test if the proxied are good.

However, on linux platform, I don't know any software functioning like this.

Does anyone know the software with this function?
Could you please tell me what it is and where to download?

Thank you very much!
