Shadowsocks-libev - GitHub

Shadowsocks-libev – GitHub

Shadowsocks-libev is a lightweight secured SOCKS5
proxy for embedded devices and low-end boxes.
It is a port of Shadowsocks
created by @clowwindy, and maintained by
@madeye and @linusyang.
Current version: 3. 3. 5 | Changelog
Shadowsocks-libev is written in pure C and depends on libev. It’s designed
to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible.
For a full list of feature comparison between different versions of shadowsocks,
refer to the Wiki page.

Install from repository (not recommended)
Shadowsocks-libev is available in the official repository for following distributions:
Debian 8 or higher, including oldoldstable (jessie), old stable (stretch), stable (buster), testing (bullseye) and unstable (sid)
Ubuntu 16. 10 or higher
sudo apt update
sudo apt install shadowsocks-libev
Supported distributions:
Debian 8, 9 or higher
Ubuntu 14. 04 LTS, 16. 10 or higher
You can build shadowsocks-libev and all its dependencies by script:
mkdir -p ~/build-area/
cp. /scripts/ ~/build-area/
cd ~/build-area. /
For older systems, building packages is not supported.
Please try to build and install directly from source. See the Linux section below.
Note for Debian 8 (Jessie) users to build their own deb packages:
We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy. If you insist on building from source, you will need to manually install libsodium from jessie-backports-sloppy, NOT libsodium in main repository.
For more info about backports, you can refer Debian Backports.
cd shadowsocks-libev
sudo sh -c ‘printf “deb jessie-backports main” > /etc/apt/’
sudo sh -c ‘printf “deb jessie-backports-sloppy main” >> /etc/apt/’
sudo apt-get install –no-install-recommends devscripts equivs
mk-build-deps –root-cmd sudo –install –tool “apt-get -o Debug::pkgProblemResolver=yes –no-install-recommends -y”. / && dpkg-buildpackage -b -us -uc
sudo dpkg -i shadowsocks-libev*
Note for Debian 9 (Stretch) users to build their own deb packages:
We strongly encourage you to install shadowsocks-libev from stretch-backports. If you insist on building from source, you will need to manually install libsodium from stretch-backports, NOT libsodium in main repository.
sudo sh -c ‘printf “deb stretch-backports main” > /etc/apt/’
# Edit the configuration file
sudo vim /etc/shadowsocks-libev/
# Edit the default configuration for debian
sudo vim /etc/default/shadowsocks-libev
# Start the service
sudo /etc/init. d/shadowsocks-libev start # for sysvinit, or
sudo systemctl start shadowsocks-libev # for systemd
Recent Fedora versions (until EOL)
RHEL 6, 7 and derivatives (including CentOS, Scientific Linux)
If you are using CentOS 7, you need to install these prerequirements to build from source code:
yum install epel-release -y
yum install gcc gettext autoconf libtool automake make pcre-devel asciidoc xmlto c-ares-devel libev-devel libsodium-devel mbedtls-devel -y
sudo pacman -S shadowsocks-libev
Please refer to downstream PKGBUILD
script for extra modifications and distribution-specific bugs.
nix-env -iA adowsocks-libev
In general, you need the following build dependencies:
autotools (autoconf, automake, libtool)
libpcre3 (old pcre library)
asciidoc (for documentation only)
xmlto (for documentation only)
Notes: Fedora 26 libsodium version >= 1. 0. 12, so you can install via dnf install libsodium instead build from source.
If your system is too old to provide libmbedtls and libsodium (later than v1. 8), you will need to either install those libraries manually or upgrade your system.
If your system provides with those libraries, you should not install them from source. You should jump this section and install them from distribution repository instead.
For some of the distributions, you might install build dependencies like this:
# Installation of basic build dependencies
## Debian / Ubuntu
sudo apt-get install –no-install-recommends gettext build-essential autoconf libtool libpcre3-dev asciidoc xmlto libev-dev libc-ares-dev automake libmbedtls-dev libsodium-dev
## CentOS / Fedora / RHEL
sudo yum install gettext gcc autoconf libtool automake make asciidoc xmlto c-ares-devel libev-devel
## Arch
sudo pacman -S gettext gcc autoconf libtool automake make asciidoc xmlto c-ares libev
# Installation of libsodium
export LIBSODIUM_VER=1. 16
tar xvf libsodium-$
pushd libsodium-$LIBSODIUM_VER. /configure –prefix=/usr && make
sudo make install
sudo ldconfig
# Installation of MbedTLS
export MBEDTLS_VER=2. 6. 0
tar xvf mbedtls-$
pushd mbedtls-$MBEDTLS_VER
make SHARED=1 CFLAGS=”-O2 -fPIC”
sudo make DESTDIR=/usr install
# Start building. / &&. /configure && make
You may need to manually install missing softwares.
Shadowsocks-libev is available in FreeBSD Ports Collection. You can install it in either way, pkg or ports.
pkg (recommended)
pkg install shadowsocks-libev
cd /usr/ports/net/shadowsocks-libev
make install
Edit your file. By default, it’s located in /usr/local/etc/shadowsocks-libev.
To enable shadowsocks-libev, add the following rc variable to your /etc/ file:
Start the Shadowsocks server:
service shadowsocks_libev start
By default, shadowsocks-libev is running as a server in FreeBSD. If you would like to start shadowsocks-libev in client mode, you can modify the rc script (/usr/local/etc/rc. d/shadowsocks_libev) manually.
# modify the following line from “ss-server” to “ss-local”
Note that is simply a workaround, each time you upgrade the port your changes will be overwritten by the new version.
The OpenWRT project is maintained here:
For OS X, use Homebrew to install or build.
Install Homebrew:
ruby -e “$(curl -fsSL)”
Install shadowsocks-libev:
brew install shadowsocks-libev
To build Windows native binaries, the recommended method is to use Docker:
On Windows: double-click in dockermingw
On Unix-like system:
cd shadowsocks-libev/docker/mingw
A tarball with 32-bit and 64-bit binaries will be generated in the same directory.
You could also manually use MinGW-w64 compilers to build in Unix-like shell (MSYS2/Cygwin), or cross-compile on Unix-like systems (Linux/MacOS). Please refer to build scripts in docker/mingw.
Currently you need to use a patched libev library for MinGW:
Notice that TCP Fast Open (TFO) is only available on Windows 10, 1607 or later version (precisely, build >= 14393). If you are using 1709 (build 16299) or later version, you also need to run the following command in PowerShell/Command Prompt as Administrator and reboot to use TFO properly:
netsh int tcp set global fastopenfallback=disabled
As you expect, simply pull the image and run.
docker pull shadowsocks/shadowsocks-libev
docker run -e PASSWORD= -p:8388 -p:8388/udp -d shadowsocks/shadowsocks-libev
More information about the image can be found here.

Transparent proxy
The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router.
# Create new chain

Transparent proxy (pure tproxy)
Executing this script on the linux host can proxy all outgoing traffic of this machine (except the traffic sent to the reserved address). Other hosts under the same LAN can also change their default gateway to the ip of this linux host (at the same time change the dns server to 1. 1. 1 or 8. 8. 8, etc. ) to proxy their outgoing traffic.
Of course, the ipv6 proxy is similar, just change iptables to ip6tables, ip to ip -6, 127. 1 to::1, and other details.
#! /bin/bash
start_ssredir() {
# please modify MyIP, MyPort, etc.

Security Tips
For any public server, to avoid users accessing localhost of your server, please add –acl acl/ to the command line.
Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend
setting up your server’s firewall rules to limit connections from each user:
# Up to 32 connections are enough for normal usage
iptables -A INPUT -p tcp –syn –dport ${SHADOWSOCKS_PORT} -m connlimit –connlimit-above 32 -j REJECT –reject-with tcp-reset

Install And Use Shadowsocks Command Line Client on Linux

Install And Use Shadowsocks Command Line Client on Linux

In a previous post, I showed you how to build a shadowsocks server on your own server and install the client software on your Linux, Windows, and Mac Desktop. And also on your Android and iOS devices. This article will show you how to install and use the command line client on Linux including Debian, Ubuntu, Fedora, CentOS, OpenSUSE and Archlinux.
Install the Command Line Client
If you prefer command line client, then you can install it on your Linux with the following command.
sudo apt-get install python-pip
sudo pip install shadowsocks
Yes, you can use the above commands to install shadowsocks client on ubuntu. But it will install it under ~/ directory and it causes loads of trouble. So I suggest using su to become root first and then issue the following two commands.
apt-get install python-pip
pip install shadowsocks
sudo yum install python-setuptools or sudo dnf install python-setuptools
sudo easy_install pip
sudo zypper install python-pip
sudo pacman -S python-pip
As you can see the command of installing shadowsocks client is the same to the command of installing shadowsocks server, because the above command will install both the client and the server. You can verify this by looking at the installation script output
Downloading/unpacking shadowsocks
Running (path:/tmp/pip-build-PQIgUg/shadowsocks/) egg_info for package shadowsocks
Installing collected packages: shadowsocks
Running install for shadowsocks
Installing sslocal script to /usr/local/bin
Installing ssserver script to /usr/local/bin
Successfully installed shadowsocks
Cleaning up…
sslocal is the client software and ssserver is the server software. On some Linux distros such as ubuntu, the shadowsocks client sslocal is installed under /usr/local/bin. On Others such as Arch sslocal is installed under /usr/bin/. Your can use whereis command to find the exact location.
[email protected]:~$ whereis sslocal
sslocal: /usr/local/bin/sslocal
Create a Configuration File
we will create a configuration file under /etc/
sudo vi /etc/
Put the following text in the file. Replace server-ip with your actual IP and set a password.
“local_address”: “127. 0. 1”,
Save and close the file. Next start the client using command line
sslocal -c /etc/
To run in the background
sudo sslocal -c /etc/ -d start
Auto Start the Client on System Boot
Edit /etc/ file
Put the following line above the exit 0 line:
Save and close the file. Next time you start your computer, shadowsocks client will automatically start and connect to your shadowsocks server.
Check if It Works
After you rebooted your computer, enter the following command in terminal:
sudo systemctl status rvice
If your sslocal command works then you will get this ouput:
● rvice – /etc/ Compatibility
Loaded: loaded (/etc/systemd/system/rvice; enabled; vendor preset: enabled)
Active: active (running) since Fri 2015-11-27 03:19:25 CST; 2min 39s ago
Process: 881 ExecStart=/etc/ start (code=exited, status=0/SUCCESS)
CGroup: /
├─ 887 watch -n 60 su matrix -c ibam
└─1112 /usr/bin/python /usr/local/bin/sslocal -c /etc/shadowsocks….
As you can see from the last line, the sslocal command created a process whose pid is 1112 on my machine. It means shadowsocks client is running smoothly. And of course you can tell your browser to connect through your shadowsocks client to see if everything goes well.
If for some reason your /etc/ script won’t run, then check the following post to find the solution.
How to enable /etc/ with Systemd
