arkcserver 0.2.0

A lightweight proxy designed to be proof to IP blocking measures

ArkC is a lightweight proxy designed to be proof to IP blocking measures and offer high proxy speed via multi-connection transmission and swapping connections.

ArkC-Server is the server-side utility.

Setup and Requirement

Running ArkC-Server requires Python 2.7 and Twisted (Python 3 is currently not supported for compatibility issues) and txsocksx. A virtual environment is generally recommended.

sudo pip install arkcserver

You may need python development environment.

Debian/Ubuntu users:

sudo apt-get install python python-pip python-dev

Fedora users:

sudo yum python python-pip python-devel

You may also install ArkC Server from source.

Privilege

By default ArkC Server needs to listen to port 53 to support DNS relay function (client may connect to server through multiple steps of DNS queries). Usually this requires pre-configuration or root privillege.

Usage

Run

arkcserver [-h] [-v] [-ep (use external proxy)] [-c <Path of the config Json file, default = config.json>]

In this version, any private certificate should be in the form of PEM without encryption, while any public certificate should be in the form of ssh-rsa.

For the configuration file, you can find an example here:

{
    "local_cert_path": "testfiles/server",
    "clients": [
        ["testfiles/client1.pub", <sha1 of client1's private key>],
        ["testfiles/client2.pub", <sha1 of client2's private key>]
    ]
}

For a full list of settings:

Index name	Value Type & Description	Required / Default
udp_port	int, udp listening port	(0.0.0.0:)53
proxy_port	int, local/ext proxy port	8100(local)/8123(ext)
local_cert_path	str, path of server pri	REQUIRED
clients	list, (path of client pub, sha1 of client pri) pairs	REQUIRED
pt_exec	str, command line of pluggable transport executable	“obfs4proxy”
obfs_level	integer, obfs level 0~3	0
meek_url	str, URL of meek’s GAE destination	“https://arkc-reflect.appspot.com/”
socks_proxy	list, (host, port)	None (Unused)

Note: if obfs_level is set to a non-zero value, obfs4_exec must be appropriate set. Obfs4 will use an IAT mode of (obfs_level - 1), which means if obfs_level is set to 2 or 3, the connection speed may be affected.
