[issue1869] openssh update key problems

[Alex Hornung]

And here comes the resolution. Seems that having an id_rsa.pub file in
~/.ssh makes stuff not work properly.

10:06:22 dragon:~
1 # ls .ssh
id_rsa          id_rsa.pub      identity        known_hosts
10:16:59 dragon:~
# mv .ssh/id_rsa.pub .
10:17:05 dragon:~
# ssh alexh at leaf.dragonflybsd.org
