[strongSwan] Failure connecting VICI socket: permission denied

[Noel Kuntze]

Hello Terry,

Of course it aborts. %any is neither an IP address, nor an FQDN.

Check the output of `which ipsec` to figure out where your shell gets it from. Make sure it uses only libs that belong to your compiled version. You likely mixed up
the files of the package with your self compiled ones. Uninstall the package. nhrp already told you, that the wrong version is in use on your system.
Build the software the exact same way Timo does. Otherwise you will fail in one way or another. You do not know enough yourself to do this right without help.
The best way for you, and to keep it maintained, is to just get the debian package source files of the package and change it to build from the source that supports nhrp.

Kind regards

Noel
