There are no problems in ssh communication among OpenBSD and Alpine Linux boxes. xen1:~# more /etc/alpine-release 3.13.1 xen1:~# uname -a Linux xen1.int.autonlab.org 5.10.11-1-lts #2-Alpine SMP Fri, 29 Jan 2021 16:43:14 +0000 x86_64 Linux xen1:~# echo $SHELL /bin/ash xen1:~# ssh au...@lnms.int.autonlab.org Host key fingerprint is SHA256:FGVw4gkiFuoDdbDg4+U/ZzyZh/pXaI//4jai+eBHzSE +---[ECDSA 256]---+ |. *oo . +o+ | |.= + . o * | |oo.. + | |+ + .
