Aliyun-based SSH tunneling ArkC client & End user client release

We here announce that an end user client based on python is released.

Currently we have an Aliyun based server in China Mainland for users to test it. Please access the server with the above script.

The server listens at, port 22. Login without shell executed using the following credentials:

User = arkc, Private key = (here to download).

In this Aliyun server, the client-side HTTP proxy listens at

ArkC V0.2 Beta2

Here we have ArkC V0.2 Beta2 at our github repo. While we’re still optimizing user performance for the big release of ArkC V0.2, you may try it right now via the source code page.

We would like to thank you for who had provided suggestions to ArkC.

Please note: now we have a GUI-based ArkC Client and can redirect all the output automatically to the form.

ArkC V0.2 Beta2 includes the following functions:

  • Full support of IPv6
  • Significantly optimized user performance, by connection selection algorithms and bug fixes
  • Client-side with fully compatible GUI

Also, please note: our testing service is updated to this new testing version, since server’s CPU intensity is significantly relieved. Users may need to switch to the latest version of client to enjoy.

Open testing service for everyone to try | 免费开放的测试代理服务

<March 15, 2016> Server will be moved to another domain with different credentials, for public usage rather than testing. Not serving now.

We offer free testing service for ArkC. You can get all the configurations and credentials you need below. But before you start, please consider reading our Quickstart guide, to make sure that ArkC is what you need.


Our control domain is “” and its NS record is set to our server at Bandwagon Host. 请把””设置作为control_domain。这是我们测试服务器所使用的域名。

Deploying ArkC does not need your own domain. On any case you can use our free aid for deployment via this page (Not ready yet). After going through the wizard you shall have CDN and domain records configured ready for you.

您不需要自己的域名,即可以运行ArkC服务。我们在这个页面(Not ready yet)提供了免费部署方案,自动为您配置内容分发网络(CDN)和域名记录,并帮您自动生成您所需要的服务器配置文件。

ArkC V0.1.2 Released

ArkC V0.1.2 is released with windows executable. Our testing ensured similar stability as existing solutions such as Shadowsocks.

We strongly encourage users to adopt this version for stability and future compatibility issues.

Windows executable & Obfuscation

Last week ArkC released a Windows executable for the client-side utility upon user requests. It can be used as a substitute with a full Python developing environment.

Note: It can only work with appropriate settings and server-side support. Should you discover any bugs in it please report it to [email protected] Ddeerreekk is working to create a easier to use toolset for setting and debugging on Windows.

So far we have no intention to provide a server-side utility as we recommend users to run Linux or Unix in their servers, which can be much safer and portable with Tor, Shadowsocks and other tools.


Besides that, we would like to let you know about our obfuscation attempt with Obfs4 by Tor project. We are integrating a ptproxy shell script into with our code so that obfuscation will be a default setting. So far, as we’ve tested, ArkC can work well integrated with Obfs4, though it requires ptproxy to run a portable proxy alone.

DNS function enabled

On Nov.28, ArkC’s dns branch is merged into master branch, after intense debugging and testing efforts.

Now ArkC starts a connection via querying certain DNS records to any local or remote standard DNS servers.

Latest status can be found at our github page.
