Hi Jason! "Jason A. Donenfeld" , 19/10/2021 – 17:51:01 (-0600): > Isn't WireGuard already in the SLES kernel? My understanding is that it should, that's why I was surprised to have to build it. But apparently not. This may be related to a specific kernel from IBM LinuxONE cloud infrastructure? | $ uname -r | 5.3.18-24.86-default But again, my knowledge of SLES is very limited (and s390x architecture even more) so I don't have any idea why this was needed. I'll be happy to help you if you need me to do some tests on the machine. Cheers! -- Faustin
