Passwordless ssh2 not working, to many authentication failures

Upon trying to setup passwordless ssh2 into my cygwin sshd server on my windows machine, I get the following error in -vvv mode

$ ssh2 -vvv -i .ssh2/id_rsa_2048_b -c aes128-ctr foobar@vm-333-333
2016-08-24 10:19:26: 6200 Broker_tcp_connect, Dst:  foobar@vm-333-333, Dst Port: 22, Src Port: -, Local username: toobar

Connection open failed; Protocol error (remote): Too many authentication failures

After reading "Too many authentication failures" I decided to add the following lines to my sshd_config file and restarting it to no avail

MaxAuthTries 30
RSAAuthentication yes  
PubKeyAuthentication yes

I piped the .ssh2/id_rsa_2048_b.pub file into both authorized keys and authroized_keys2 and all the permissions on my keys appear to be set correctly. The connection works when I enter a password. I'm not sure how to proceed.

Are you using an SSH agent? How many different keys are in your agent? – Zoredache – 2016-08-24T17:18:29.357

I don't have ssh-agent and can't install it on my current computer. – Adam W. Cooper – 2016-08-24T17:58:26.777

I checked /var/log and couldn't find anything. The sshd.log file existed but had nothing in it. – Adam W. Cooper – 2016-08-24T17:59:23.027

On the remote computer, start /usr/sbin/sshd -dDp 2222 and connect to it on port 2222. This will give you ssh server debug output. – mtak – 2016-08-24T18:11:17.060

I get prvate host key #0-3: somereallylongkeythatisreallyneatandstuff – Adam W. Cooper – 2016-08-24T19:14:45.013

and /var/empty must be owned by root and not group or world-writable – Adam W. Cooper – 2016-08-24T19:15:16.340
