Hi: I have two boxes connected to the same router. One runs SL7.5,
from tomorrow probably SL7.6, which is an el7 clone, and the other runs
Fedora 28.
I can ssh and rsync from F28 to SL7, but permission is denied in the
opposite direction. Port 22 is open. I now have copies of both
versions of /etc/sshd and intend to examine diffs.
Google provides many links but nothing that looks authoritative or,
preferably, authoritative and simple. Any help wpuld be appreciated.
