This tutorial will show you how to install SoftEther VPN on Ubuntu 22.04.
Step 1 – Install SoftEther VPN
First, install the required packages using the following command:
apt-get install build-essential gnupg2 gcc make -y
Next, download the SoftEther VPN Server package from the official website. You can use wget to download the package directly from the command line:
wget http://www.softether-download.com/files/softether/v4.38-9760-rtm-2021.08.17-tree/Linux/SoftEther_VPN_Server/64bit_-_Intel_x64_or_AMD64/softether-vpnserver-v4.38-9760-rtm-2021.08.17-linux-x64-64bit.tar.gz
Once the download is complete, extract the contents of the package using the following command:
tar -xvzf softether-vpnserver-v4.38-9760-rtm-2021.08.17-linux-x64-64bit.tar.gz
Change into the extracted directory:
cd vpnserver
Run the make command to build the SoftEther VPN Server:
make
Once the build process is complete, move the vpnserver directory to /usr/local/:
cd .. mv vpnserver /usr/local/
Set the correct permissions for the vpnserver directory:
cd /usr/local/vpnserver/ chmod 600 * chmod 700 vpnserver chmod 700 vpncmd
Step 2 – Create a Systemd File for SoftEther
Next, you will need to create a service file to start and stop SoftEther VPN.
You can create an init service file using the following command:
nano /etc/init.d/vpnserver
Add the following lines:
#!/bin/sh
# chkconfig: 2345 99 01
# description: SoftEther VPN Server
DAEMON=/usr/local/vpnserver/vpnserver
LOCK=/var/lock/subsys/vpnserver
test -x $DAEMON || exit 0
case "$1" in
start)
$DAEMON start
touch $LOCK
;;
stop)
$DAEMON stop
rm $LOCK
;;
restart)
$DAEMON stop
sleep 3
$DAEMON start
;;
*)
echo "Usage: $0 {start|stop|restart}"
exit 1
esac
exit 0
Next, create a subsys directory and set execution permission to the service file.
mkdir /var/lock/subsys chmod 755 /etc/init.d/vpnserver
Finally, start SoftEther VPN using the following command:
/etc/init.d/vpnserver start
You will see the following output.
Let's get started by accessing to the following URL from your PC: https://69.28.85.145:5555/ or https://69.28.85.145/ Note: IP address may vary. Specify your server's IP address. A TLS certificate warning will appear because the server uses self signed certificate by default. That is natural. Continue with ignoring the TLS warning.
Next, add the SoftEther VPN service to start at the system reboot.
update-rc.d vpnserver defaults
Step 3 – Configure SoftEther VPN Server
Next, you will need to configure the SoftEther VPN Server using the vpncmd command line tool.
Change to the directory where the SoftEther VPN Server is installed. By default, it is located in /usr/local/vpnserver/:
cd /usr/local/vpnserver
Run the vpncmd utility to access the SoftEther VPN Server console:
./vpncmd
You will be asked to choose from the following options:
