Using V2Ray to break through network blockade and access the Internet is undoubtedly the best choice at present. On the Windows platform, we have many choices, such as v2rayN and Clash; on the Mac platform, we can use ClashX, etc. But for Linux systems, we have even fewer choices. Fortunately, a very useful and highly extensible V2Ray GUI frontend on Linux is Qv2ray.

Unfortunately, all characteristics of Shadowsocks (SS) and ShadowsocksR (SSR) have been fully and absolutely identified and controlled by GFW ("thanks to" the forced compromise from their developers). In short, as long as the GFW wants to block your VPS, it can now do this easily and perfectly in less than 30 seconds. If you find that your SS/SSR is still working well, that means GFW has no interest or there is no need to ban you right now. Of course, each blocking cycle of GFW is about 10 weeks. Therefore, we can roughly calculate when our VPS can be unblocked.
