Install SoftEther client in CentOS

This tutorial will explain how to install SoftEther client in a linux machine. This is pretty straight forward for both debian based distros also. Please check the server part first

  1. First download source code, unpack it and compile

[root@Client home]# wget http://www.softether-download.com/files/softether/v4.05-9416-beta-2014.02.06-tree/Linux/SoftEther%20VPN%20Client/64bit%20-%20Intel%20×64%20or%20AMD64/softether-vpnclient-v4.05-9416-beta-2014.02.06-linux-x64-64bit.tar.gz
[root@Client home]# tar -zxvf softether-vpnclient-v4.05-9416-beta-2014.02.06-linux-x64-64bit.tar.gz
[root@Client home/vpnclient]# cd vpnclient
[root@Client home/vpnclient]# make

In make select yes on all accounts, otherwise it won’t compile.

  1. Install it

[root@Client home/vpnclient]# mkdir /usr/bin/vpnclient
[root@Client home/vpnclient]# cp vpn* /usr/bin/vpnclient/
[root@Client home/vpnclient]# cp hamcore.se2 /usr/bin/vpnclient/
[root@Client home/vpnclient]# vim /etc/init.d/vpnclient

#!/bin/sh
# chkconfig: 2345 99 01
# description: SoftEther VPN Client
DAEMON=/usr/bin/vpnclient/vpnclient
LOCK=/var/lock/subsys/vpnclient
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
  1. Start daemon and make sure it will start after a reboot

[root@Client home/vpnclient]# chmod 755 /etc/init.d/vpnclient
[root@Client home/vpnclient]# service vpnclient start
SoftEther VPN Client Service Started.
[root@Client home/vpnclient]# chkconfig --add vpnclient

  1. Configure client

As I stated in the previous server example, this is the best example I’ve come up with. I don’t even know if there’s a better way to do this but there probably is. But for now I’m sticking with what I know that is working quite well.

Run vpncmd by executing /usr/local/vpnclient/vpncmd and selecting option number 2 and press enter until VPN Client> prompt shows up.

VPN Client> NicCreate myadapter
VPN Client> AccountCreate myconnection
(e.g.Server: serverip:port, Virtual HUB:VPN, Virtual Adaptar: myadapter)
VPN Client> AccountUsernameSet myconnection
VPN Client> AccountPasswordSet myconnection
(set password, choose standard)
VPN Client> AccountConnect myconnection
VPN Client> AccountStartupSet myconnection

And that’s it you should be all done. If you have any problems please check the log at /usr/local/vpnclient/client_log/* or vpnserver in case you’re in the server.

I tried using the SecureNat DHCP server but ended up losing all of my clients connections. In order to connect different clients just go to your command line and add the ip address to your adapter like this. Do this in all the clients you setup.

[root@Client home/vpnclient]# ifconfig vpn_myadapter
vpn_myadapter Link encap:Ethernet HWaddr 00:AC:4B:C4:92:82
…..
[root@Client home/vpnclient]# ifconfig vpn_myadapter 172.16.0.3/24
[root@Client home/vpnclient]# ifconfig vpn_myadapter
