If you have a VPN account from CITeS (Center for IT Services - UoM) and you want to configure your SoftEther VPN client on your ubuntu machine, this is the best guide for you. This blog post is a conversion to the linux environment from the guide here given for windows environment . I’ll explore the steps in general and give the example using CITeS VPN account. So you can apply the same procedure for another VPN server account too.
As a prerequisite you should have created an account from a VPN server. (For this case from CITeS VPN server)
1. Download and Install SoftEther VPN Client
- Download SoftEther VPN Client software from their official website (https://www.softether.org)
- Navigate to
Download — > Download SoftEther VPN
Download SoftEther VPN link.
Select Component : SoftEther VPN Client
Select Platform : Linux
Select CPU : Select the appropriate CPU from the Drop down
4. Click on the appropriate downloading link based on the version of the software.
5. Extract the downloaded tar.gz file. Here after I will refer the extracted folder as <vpnclient>
6. Navigate to <vpnclient>folder and open a terminal.
make command and accept all license agreements by entering the number relevant to “Yes”.
8. After the completion of
make command process, start the vpn client using:
sudo ./vpnclient start
9. Then you will get the following message.
10. Before going to the configuration part please test the VPN client installation.
./vpncmd and select No
3 to enter to
Use of VPN Tools (certificate creation and Network Traffic Speed Test Tool) option.
12. Then run
If all tests are passed, you are good to go.
Ctrl+C to terminate that process.
2. Configure SoftEther VPN Client
./vpncmdon a terminal opened inside the <vpnclient> folder.
- Select №2 to enter to the
Management of VPN Clientoption.
- Press Enter when you are asked for
Hostname of IP Address of Destination
- Then you will connect to the
5. Create a virtual interface to connect to the VPN server.
NicCreate <name for virtual interface>
6. Create an VPN client account using the following command.
In this case :
7. Then setup the account with your details.
Destination VPN Server Host Name and Port Number:<VPN IP address>:<SoftEther VPN Port>
Destination Virtual Hub Name: <Hub Name>
Connecting User Name: <Username of LMS, Moodle, UoM_Wireless, UoM Email>
Used Virtual Network Adapter Name: <Created virtual interface’s name>
Destination VPN Server Host Name and Port Number:svpn.mrt.ac.lk:443
Destination Virtual Hub Name: <Enter the appropriate one according to the following drop down>
Connecting User Name: <Username of LMS/ Moodle/ UoM_Wireless/ UoM Email>
Used Virtual Network Adapter Name: vpn_se (earlier created one)
You will get
The command completed successfully message if you do it correctly.
8. Setup a password to the created account.
AccountPassword <account name>
Set a password and confirm it. SPECIALLY, for CITeS account you should give
LMS/ Moodle/ UoM_Wireless/ UoM Email password
Specify standard or radius: input give
9. Now you can connect to the SoftEther VPN clinet account through the created account. For that issue:
AccountConnect <account name>
In this example:
10. Issue the command
AccountList and check the connectivity. If you get Connected status it is good to to for the next step.
3. Add Route to the Routing Table
cat /proc/sys/net/ipv4/ip_forwardto check whether ip forward is enabled in your system.
If you get “1” go to the step №2 .
If you get “0” , Navigate to
/etc/sysctl.conf file and uncomment
net.ipv4.ip_forward=1 line. Open a terminal and issue command
Then check whether you get “1” for the first step.
2. Open a terminal and issue the command
sudo ifconfig . Now you should see the virtual network adapter you created earlier. But you do not have a ip address for it.
3. Issue the command
sudo dhclient <virtual_network_adapter_name>
According to the above example :
sudo dhclient <vpn_vpn_se>
After few moments you will get an ip address from the VPN Server.
4. Then issue
sudo netstat -rn command to see the routing table. You need to add a static route here.
sudo ip route add <gateway of the ip range of your virtual network adapter>/<subnetmask> via <ip you got for the virtual network adapter>
Except the last route adding step all of the above steps are one time work.
Now you should able to connect to the required server through the VPN Client. 😃
