Here is my network configuration on an OVH server.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
root@ns3048991:~# cat /etc/network/interfaces # interfaces(5) file used by ifup(8) and ifdown(8) # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d auto eno3 iface eno3 inet static address 149.202.199.137 netmask 255.255.255.255 broadcast 149.202.199.137 gateway 149.202.199.254 dns-nameservers 8.8.8.8 8.8.4.4 root@ns3048991:~# |
To convert this interface to bridge network, do the following
1) Replace all occurance of “eno3” with “br0”
2) Add following lines
|
1 2 3 |
bridge_ports eno3 bridge_stp off bridge_maxwait 5 |

XFCE is a light weight desktop for Linux. XFCE + vnc allow you to setup remote desktop on a VPS or dedicated server located on a data center or cloud. You can connect to remote desktop using VNC client and work like it is local computer.

It is bad idea to use root user for logging into desktop. Create a normal user to run desktop.
|
1 |
useradd -m -s /bin/bash USERNAME_HERE |
It will be good to make this user an admin, so user can install software or update system.
|
1 |
usermod -aG sudo USERNAME_HERE |
Now login as the user
|
1 |
su - USERNAME_HERE |
Create a vnc password for this user.
|
1 |
vncpasswd |
Create vnc startup file
|
1 |
vi ~/.vnc/xstartup |
Add
|
1 2 3 4 5 6 7 |
#!/bin/bash xrdb $HOME/.Xresources /usr/bin/vncconfig -nowin -display :1 & startxfce4 & |
Make it executable
|
1 |
chmod 755 ~/.vnc/xstartup |
Now exit the user with “exit” command. You should be user “root” now.
To auto start vncserver on boot, you need to create a service file.
|
1 |
vi /etc/systemd/system/vncserver@.service |
Add
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
[Unit] Description=VNC server startup script After=syslog.target network.target [Service] Type=forking User=USERNAME_HERE ExecStartPre=-/usr/bin/vncserver -kill :%i &> /dev/null ExecStart=/usr/bin/vncserver -depth 24 -geometry 1920x1080 :%i PIDFile=/home/USERNAME_HERE/.vnc/%H:%i.pid ExecStop=/usr/bin/vncserver -kill :%i [Install] WantedBy=multi-user.target |
Enable the service with

ShadowSocks client is part of shadowsocks package. This include both client and server. If you are looking to install server, see Install ShadowSocks server on Debian 10
To install ShadowSocks, run
|
1 |
apt install -y shadowsocks |
ShadowSocks client is called sslocal, get installed in /usr/bin/sslocal.
On Ubuntu, no start up script provided with this package, so you need to create one or manually run sslocal when required.
Create a service file
|
1 |
vi /lib/systemd/system/shadowsocks-local@.service |
Add following content
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
[Unit] Description=Shadowsocks client mode service Documentation=man:sslocal(1) After=network-online.target [Service] Type=simple User=nobody Group=nogroup ExecStart=/usr/bin/sslocal -q -c /etc/shadowsocks/%i.json Restart=on-failure RestartSec=30 [Install] WantedBy=multi-user.target |
Now we need to create a configuration file with your ShadowSocks server IP and password.

mkdir /etc/shadowsocks/ vi /etc/shadowsocks/local.json |
Add following content
|
1 2 3 4 5 6 7 8 9 10 11 12 |
{ "server":"YOUR_SERVER_IP", "server_port":8044, "local_address": "127.0.0.1", "local_port":8044, "password":"PASSWORD", "timeout":300, "method":"aes-256-cfb", "fast_open": false, "workers": 1, "prefer_ipv6": false } |
“server” = IP of the server where you installled ShadowSocks server.
“server_port” = Port used by ShadowSocks server
“password” = ShadowSocks server password.
local_port can be anything you like.
Enable shadowsocks service

1 |
systemctl enable shadowsocks-local@local |
To start
