host A ubuntu 14.04.3 -- running ssh-server
client B and C
client B 14.04.3 can connect no problem with ssh keys only to host A
(to me this means openssh-server is fine on Host A)
Client C 15.10 cannot ssh to host A, openssh cannot or refuses to load
identity files; output of ssh -vvv below
$ ssh ubuntu@172.27.20.1 -vv

###at this point connection hangs -- sometimes i get back
"ssh_exchange_identification: read: Connection reset by peer"
permissions on files look OK to me:
$ ls -all .ssh
total 24
drwx------ 2 user user 4096 Jan 15 12:53 .
drwxr-xr-x 26 user user 4096 Jan 15 12:13 ..
-rw-r--r-- 1 user user 396 Jan 15 12:53 authorized_keys
-rw------- 1 user user 1679 Jan 14 16:15 id_rsa
-rw-r--r-- 1 user user 395 Jan 14 16:15 id_rsa.pub
-rw-r--r-- 1 user user 1094 Jan 15 12:18 known_hosts
and home dir :
$ ls -all /home
drwxr-xr-x 26 user user 4096 Jan 15 12:13 user
actual username replaced with "user"
