Commands beginning with the # prompt are executed as the root user, the $ prompt means the execution is from a regular user.
1. DownloadingDownload the SoftEther VPN client distro for the OS architecture from the official site or from the project repository on GitHub. For example, terminal command of downloading the client distro for Linux x64 looks like this.
$ wget https://github.com/SoftEtherVPN/SoftEtherVPN_Stable/releases/download/v4.29-9680-rtm/softether-vpnclient-v4.29-9680-rtm-2019.02.28-linux-x64-64bit.tar.gzNext unzip the downloaded archive, terminal command for it looks like this.
$ tar -xvf softether-vpnclient-v4.29-9680-rtm-2019.02.28-linux-x64-64bit.tar.gz
All described below actions have to execute in Linux terminal only.
2. InstallingChange path to the archive directory which was unzipped on previous step.
$ cd vpnclientThere is the script file .install.sh in the directory. The file name beginning with dot (.), so a graphic explorer may be doesn't find it. Run the command to verify that the file exists.

To switch the current language, open and edit the 'lang.config' file. *** How to start the SoftEther VPN Client Service *** Please execute './vpnclient start' to run the SoftEther VPN Client Background Service. And please execute './vpncmd' to run the SoftEther VPN Command-Line Utility to configure SoftEther VPN Client. Of course, you can use the VPN Server Manager GUI Application for Windows / Mac OS X on the other Windows / Mac OS X computers in order to configure the SoftEther VPN Client remotely. *** For Windows users *** You can download the SoftEther VPN Server Manager for Windows from the http://www.softether-download.com/ web site. This manager application helps you to completely and easily manage the VPN server services running in remote hosts. *** For Mac OS X users *** In April 2016 we released the SoftEther VPN Server Manager for Mac OS X. You can download it from the http://www.softether-download.com/ web site. VPN Server Manager for Mac OS X works perfectly as same as the traditional Windows versions. It helps you to completely and easily manage the VPN server services running in remote hosts. --------------------------------------------------------------------
All described below actions have to execute with the root user rights.
Use commands sudo or su to get the root user rights. For example, enter sudo su to login as root in a desktop Debian-based distros (Ubuntu, Linux Mint and others). And use su in a RedHat-based distros (RHEL, Fedora, CentOS and others) and server Debian-based distros.
3. ConfiguringRun the VPN client.
# ./vpnclient start The SoftEther VPN Client service has been started.You can proceed to import configurations after successfully launching the VPN client. Download the configs archive file and unzip it.
# unzip all.zip
It is not necessary download archive of all SoftEther configs, you may select and download a specific configs (Single chains and Double chains).Next step is importing one or more configs. For example, the command for import config of the chain DoubleSSL_PL1_RU1 looks like this.
# ./vpncmd localhost /CLIENT /CMD AccountImport DoubleSSL_PL1_RU1.vpn
Use the next command to show all imported configs (accounts).You have to set the username and password for the imported config. Replace urusername and urpassword by your username and password in the example below.
./vpncmd localhost /CLIENT /CMD AccountList
The username and password are the same as the username and password of the DeepWebVPN Cabinet.
# ./vpncmd localhost /CLIENT /CMD AccountUsernameSet double-ssl-pl1-ru1 /USERNAME:urusername # ./vpncmd localhost /CLIENT /CMD AccountPassword double-ssl-pl1-ru1 /PASSWORD:urpassword /TYPE:radiusUse the same command again to change the username or password.
4. Connect and routingUse the next command to connect.
# ./vpncmd localhost /CLIENT /CMD AccountConnect double-ssl-pl1-ru1Check the connection status after a few seconds. If connection is successful the status will change to Connected.
# ./vpncmd localhost /CLIENT /CMD AccountList vpncmd command - SoftEther VPN Command Line Management Utility SoftEther VPN Command Line Management Utility (vpncmd command) Version 4.29 Build 9680 (English) Compiled 2019/02/28 19:22:54 by yagi at pc33 Copyright (c) SoftEther VPN Project. All Rights Reserved. Connected to VPN Client "localhost". VPN Client>AccountList AccountList command - Get List of VPN Connection Settings Item |Value ----------------------------+--------------------------------------------------- VPN Connection Setting Name |double-ssl-pl1-ru1 Status |Connected VPN Server Hostname |XX.XX.XX.XX/tcp:443 (Direct TCP/IP Connection) Virtual Hub |double-ssl-pl1-ru1 Virtual Network Adapter Name|VPN The command completed successfully.You have to configure routing after successfully connecting. First of all turn on the IP forwarding.
# echo 1 > /proc/sys/net/ipv4/ip_forward # echo net.ipv4.ip_forward=1 >> /etc/sysctl.conf && sysctl -pNext step is setting IP of VPN connection.
# dhclient vpn_vpnNow you need to know the default gateway (it is 192.168.0.1 on the second line in the example below). Default gateway belongs to the interface of external network (internet connection) usually, it is wlan0 in the example.
# netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.244.1 0.0.0.0 UG 0 0 0 vpn_vpn 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0 192.168.244.0 0.0.0.0 255.255.255.0 U 0 0 0 vpn_vpnAdd new routing rule, where XX.XX.XX.XX replaced with IP of the incoming (or only server for a Single chain) server (see command ./vpncmd localhost /CLIENT /CMD AccountList) and 192.168.0.1 is a default gateway.
# ip route add XX.XX.XX.XX via 192.168.0.1Make sure there is default via 192.168.234.1 dev vpn_vpn for a Single chain in the routing table or default via 192.168.244.1 dev vpn_vpn for a Double chain (the example below is for a Double chain).
# ip route show default via 192.168.244.1 dev vpn_vpn default via 192.168.0.1 dev wlan0 proto dhcp metric 600 XX.XX.XX.XX via 192.168.0.1 dev wlan0 192.168.244.0/24 dev vpn_vpn proto kernel scope link src 192.168.244.22
It is important to remember that the gateway 192.168.234.1 is for a Single chain and 192.168.244.1 is for a Double chain. The rule of the example above is for a Double chain.Add the rule if it is not in the routing table.
# ip route add default via 192.168.244.1 dev vpn_vpnAnd remove the last gateway.
# ip route del default via 192.168.0.1Don't forget setting DNS after succesfully connecting.
5. DisconnectTurn off the client to disconnect from a SoftEther VPN chain.
# ./vpnclient stopThen remove the VPN routing rule and make back the default gateway. Don't forget replace XX.XX.XX.XX with IP of the incoming VPN server (see command ./vpncmd localhost /CLIENT /CMD AccountList).
# ip route del XX.XX.XX.XX # ip route add default via 192.168.0.1
