Fails to load a VPN profile that has more then 6 characters in it's filename

[jdenoy]

Trying to start the VPN using the profile I have failed for no reasons. After testing different filenames, I've found that the problem is the number of caracters of the filename.

Seems that above 6 characters the VPN profile fails to be loaded :

jdenoy@johand:~/.ike/sites$ docker run --rm -it --privileged --net=host -v ~/.ike/sites:/sites stono/ike 1234567 user pass

But work perfectly with a six characters VPN profil name :
