Softethervpn: v4.10-9505-beta can not work on Ubuntu 14.04

This wont help, but I am running SoftEther on ubuntu 14.04 without any problems.

I have linux mint 17.1 (based on Ubuntu 14.04), works without problems so far (server + client).
Im use the latest LTS kernel available:

$ sudo apt-get install linux-image-generic-lts-utopic linux-headers-generic-lts-utopic
$ reboot

Kind regards,

I meet the same problem. just run it by root, everything wil be fine.
$ sudo vpnserver start

I had this problem when I moved the executables out of the build directory. Moving them back in and running vpnserver from here fixed the issue.

$ ls -al vpnserver/

$ ./vpnserver -v

vpnserver command usage:
 vpnserver start  - Start the SoftEther VPN Server service.
 vpnserver stop   - Stop the SoftEther VPN Server service if the service has been already started.

Have same problem and windows and problem remain even if run as admin. a file with same name exist in directory but 0KB in size. Attempt to uninstall give same problem which make me impossible to reinstall

The problem is due to hamcore.se2 under /bin/vpnbridge, /bin/vpnclient, /bin/vpncmd, /bin/vpnserver is root access only.

$ ls -al /usr/vpnserver/hamcore.se2
-rw------- 1 root root 1296234 Mar  6 07:05 /usr/vpnserver/hamcore.se2

so just run the command sudo vpnserver start

This issue is a couple of years old and there are many good answers here, and I personally couldn't reproduce it, when installing under /opt and giving the correct permissions.
vpnserver is supposed to run with sudo.

If things are working fine now, I'd like to close this issue in the next few days

PR #339 Solves this problem for vpncmd. vpnserver should be started as root. For vpnclient, I am not sure

@moatazelmasry2 Do you want to fix _vpnclient_? I will research. I personally have this convention:

• Start vpnserver and vpnclient as _root_, because they are services.
• Start vpncmd as normal user, because it is run one-off and there is already admin password to protect system config.

@hongquan yes true. So this issue has been answered correctly. Closing this issue

I know this is closed, but as I stumbled on this issue on Ubuntu 18.04, here's what I've found. If I'm in my home directory:

~$ sudo vpncmd
-- Alert: SoftEther VPN Kernel --
Fatal Error: The file "hamcore.se2" is missing or broken.
Please check hamcore.se2.

(First, reboot the computer. If this problem occurs again, please reinstall VPN software files.)

However the file is present:

~$ ls -la /usr/local/vpnserver | grep se2
-rw-------  1 root root 1296250 Jan 15  2018 hamcore.se2

Just cd to that directory does not work:

~$ (cd /usr/local/vpnserver && sudo vpncmd)
-- Alert: SoftEther VPN Kernel --
Fatal Error: The file "hamcore.se2" is missing or broken.
Please check hamcore.se2.

(First, reboot the computer. If this problem occurs again, please reinstall VPN software files.)

... however, explicitly calling the vpncmd in that directory does:

~$ (cd /usr/local/vpnserver && sudo ./vpncmd)
vpncmd command - SoftEther VPN Command Line Management Utility
SoftEther VPN Command Line Management Utility (vpncmd command)
Version 4.25 Build 9656   (English)

By using vpncmd program, the following can be achieved. 

1. Management of VPN Server or VPN Bridge 
2. Management of VPN Client
3. Use of VPN Tools (certificate creation and Network Traffic Speed Test Tool)

Select 1, 2 or 3: ^C

Note that vpncmd is a symlink, if you've used softether.sh to install:

~$ ls -la `which vpncmd` 
lrwxrwxrwx 1 root root 27 Feb 23 19:43 /usr/local/bin/vpncmd -> /usr/local/vpnserver/vpncmd

My guess is, the vpncmd tries to get the path to itself, and then looks for hamcore.se2 in the same directory; however, it probably does not resolve symlinks, so ends up with /usr/local/bin/ as the path to itself instead of the correct /usr/local/vpnserver/, looks in there for hamcore.se2, doesn't find it, and fails.

Why not to open new issue?
