Trojan

Install trojan client on Ubuntu

For 18.10 & 19.04

sudo add-apt-repository ppa:greaterfire/trojan
sudo apt-get update
sudo apt-get install trojan

For >= 19.04 

sudo apt-get install trojan

On Manjaro:

sudo pacman -S trojan

Reference: Binary & Package Distributions · trojan-gfw/trojan Wiki

Trojan client config

Put config.json under /etc/trojan/config.json (for Arch) 或者 /usr/local/trojan/config.json (for Ubuntu)

sudo mv /etc/trojan/config.json /etc/trojan/config.json.backup
sudo vi /etc/trojan/config.json

To test that trojan is working, run the one-time command:

/usr/local/trojan/trojan -c /usr/local/trojan/config.json

Run on system daemon

Simply, enable trojan：

systemctl enable trojan
systemctl start trojan

If trojan service isn’t available: 

cd /etc/systemd/system/
sudo vi trojan.service

Input: 

[Unit]
Description=trojan
Documentation=man:trojan(1) https://trojan-gfw.github.io/trojan/config https://trojan-gfw.github.io/trojan/
After=network.target

[Service]
Type=simple
StandardError=journal
User=nobody
AmbientCapabilities=CAP_NET_BIND_SERVICE
ExecStart=/usr/local/trojan/trojan -c /usr/local/trojan/config.json
ExecReload=/bin/kill -HUP $MAINPID
Restart=on-failure
RestartSec=3s

[Install]
WantedBy=multi-user.target

Then add to auto-run and config system-wide alias: 

systemctl enable trojan

Optionally, add alias for quick run: 

sudo vi ~/.bashrc
# add the following line:
alias trojan='/usr/local/trojan/trojan -c /usr/local/trojan/config.json'

Above, configed trojan successfully on system level. Welcome to beyound the wall.

Browser config

Next step, download SwitchyOmega for Chrome and Firefox, config SOCKS5

Download url: https://github.com/FelisCatus/SwitchyOmega/releases

Local file:

  1. https://mar2ndx.github.io/files/proxy_switchyomega-2.5.20-an+fx.xpi
  2. https://mar2ndx.github.io/files/SwitchyOmega_Chromium.crx

Go to switchyomega config and set (default) to “SOCKS5” protocol and “127.0.0.1” server, “1080” port.

Done!

Known Issue

If you see “unknown protocol” error, then you have mis-configed http instead of socks5.

Qv2ray

Qv2ray仅需下载以下三件套：

  1. Main app: https://github.com/Qv2ray/Qv2ray/releases

  2. Trojan plugin: https://github.com/Qv2ray/QvPlugin-Trojan/releases/tag/v3.0.0-pre3

    1. 注意：trojan plugin 和 qv2ray 版本必须对应

  3. v2core: https://github.com/v2fly/v2ray-core/releases

    1. 或者 https://github.com/v2ray/v2ray-core/releases
    2. 注意选择：v2ray-linux-64.zip

After installation

Troubleshoot

Check IP address

curl ifconfig.me

Test VPN

Test whether proxy / trojan really works

curl google.com
echo $https_proxy

Use another machine as proxy

假如 somehow 你的机器无法 config proxy，你可以使用另一台机器：

  1. 在公用机器上 Config Qv2ray: 监听地址 = 0.0.0.0

  1. 在私人机器上 Set manual proxy:

    Proxy: （公用机器的地址，比如 192.168.31.105）
    Port: 8889

Terminal proxy

对于 Qv2ray: 

export http_proxy=http://127.0.0.1:8889
export https_proxy=http://127.0.0.1:8889

或者：

export http_proxy=http://127.0.0.1:8889
export https_proxy=socks5://127.0.0.1:1089

然后加入 alias：

sudo vi ~/.bashrc

Content：

alias fanqiang='export http_proxy=http://127.0.0.1:8889 && export https_proxy=socks5://127.0.0.1:1089'
