I built a strongSwan on my VPS linux system as the server. I planed to connect my pine64 to the server via VPN, so I installed a strongSwan in it. However when I bring the connection up, there is something wrong. I refered to strongSwan website, and find that it requires the kernel support(the modules needed) https://wiki.strongswan.org/projects/str...nelModules:
The system I had installed are Ubuntu Base Image [20161218-1] by longsleep and Ubuntu Mate  built by PINE64. However they both do not include these modules required.
So, how to insert these modules or should I recompile the kernel from the beginning.
