strongswan no start embedder linux

Solution 1:

Your problem is at a kernel level:

00[KNL] unable to create netlink socket: Protocol not supported (93)
00[KNL] received netlink error: Operation not supported (95)

Probably you are missing the xfrm_* kernel modules. You can try, e.g.:

modprobe xfrm_user

but it will probably fail.

You need to recompile the kernel with the list of required kernel modules from StrongSwan's wiki.
