Setting up Shadowsocks to work with OpenVPN on Ubuntu 20.04/22.04

NOTICE: dual-stack mode for '--proto udp' does not work correctly with '--socks-proxy'

This instruction is only for TCP config.

1.Installing shadowsocks-libev - you need to run the command in the terminal

sudo apt update ; sudo apt install shadowsocks-libev shadowsocks-v2ray-plugin resolvconf -yy

2. Next, you need to edit the configuration file by running the command in the terminal

sudo nano /etc/shadowsocks-libev/config.json

3. IP address table

+--------------------+-----------------+ | server_short_title | server_ip | +--------------------+-----------------+ | DE | 217.182.199.126 | | US | 147.135.36.162 | | CA | 66.70.179.236 | | FR | 46.105.107.231 | | GB | 185.253.98.234 | | NL | 92.38.186.85 | | LU | 92.38.162.11 | | SG | 139.99.68.157 | | MD | 178.175.139.202 | | RO | 86.105.25.218 | | IT | 91.193.5.90 | | SP | 195.206.107.202 | | RU | 95.213.164.11 | | UA | 193.106.31.98 | | PA | 190.97.163.213 | | HK | 193.239.86.18 | | TR | 31.210.70.186 | | US3 | 147.135.11.223 | | PL | 79.137.69.34 | | SE | 185.247.71.106 | | AT | 91.132.139.66 | | BE | 37.120.143.202 | | CH | 152.89.162.138 | | US2 | 5.181.234.58 | | CY | 134.255.210.26 | | RS | 89.38.224.2 | | RU2 | 5.188.163.34 | | AU | 51.161.128.135 | | FI | 95.216.15.25 | | NL-AllServers | 92.38.186.19 | | DE-AllServers | 49.12.133.171 | | LV | 188.92.78.249 | | RU4 | 176.123.175.242 | +--------------------+-----------------+

4. From the list above, select the IP by server_short_title, which is the first entry in the config file name.

copy-paste port 587

{
"server":["134.255.210.26"],
"mode":"tcp_only",
"server_port":587,
"local_port":10080,
"password":"Y0YWhQ4sACO3",
"timeout":86400,
"method":"chacha20-ietf-poly1305",
"no_delay": true,
"fast_open": false,
"reuse_port": true,
"workers": 4,
"plugin": "ss-v2ray-plugin",
"plugin_opts": "tls;host=specialsseason.com"
}

Next, close the nano editor with CTRL+X, press Y, and confirm with Enter.

Next, execute the command block.

sudo sed -i 's/ss-server/ss-local/g' /lib/systemd/system/shadowsocks-libev.service ; sudo systemctl daemon-reload; sudo service shadowsocks-libev restart; sudo service shadowsocks-libev status

The result is as in the screenshot.
Next, you need to add a line with the shadowsocks-libev settings to the OpenVPN file.
Download the Linux configuration file from your personal account.

Upload file to directory /etc/openvpn/client/ under the name 27194_RO_tcp.conf
edit with command sudo nano /etc/openvpn/client/27194_RO_tcp.conf
enter a line
socks-proxy 127.0.0.1 10080

add ShadowSocks server ip из 3. IP address table

route IP_SERVER_SS 255.255.255.255 net_gateway
redirect-gateway def1

connect-retry-max 3

Next, close the nano editor with CTRL+X, press Y, and confirm with Enter.
You can add a resolver using a command block from the terminal, specifying the path to /etc/openvpn/client/27194_RO_tcp.conf
sudo sed -i -e "15 i script-security 2" /etc/openvpn/client/27194_RO_tcp.conf
sudo sed -i -e "16 i up /etc/openvpn/update-resolv-conf" /etc/openvpn/client/27194_RO_tcp.conf
sudo sed -i -e "17 i down /etc/openvpn/update-resolv-conf" /etc/openvpn/client/27194_RO_tcp.conf

To run openvpn you need to run the command
sudo systemctl start openvpn-client@27194_RO_tcp.service

sudo systemctl status openvpn-client@27194_RO_tcp.service
