Try

Code:

ssh -vvv kick@remotemachine

This will give you the most verbose output possible.

Well, I was thinking I didn't have all the correct files on the local machine,
ssh_config is the only ssh i had in the /etc/ folder.

I decided to see how ssh would react if I didn't have ssh_config available. Instead of throwing me an error though, it actually let me slogin to the remote machine.
I'm still hella confused about ssh tho, all documentation i've found is horrible in explaining the subject.

Thanks for the reply.
After putting the ssh_config file back where it belongs, then running

Code:

ssh -vvv kick@remotemachine

I noticed a couple suspicious items in the output, which I'm not sure what to make of.

1.

Code:

debug1: An invalid name was supplied
Configuration file does not specify default realm

realm? I haven't heard this term related to ssh

2. this is the last few lines, after it "offers" the id_dsa, looks like the last 7 lines here have something to do with the problem, but I don't know what to make of it....

Code:

debug1: Next authentication method: publickey
debug1: Trying private key: /Users/Eric/.ssh/identity
debug3: no such identity: /Users/Eric/.ssh/identity
debug1: Trying private key: /Users/Eric/.ssh/id_rsa
debug3: no such identity: /Users/Eric/.ssh/id_rsa
debug1: Offering public key: /Users/Eric/.ssh/id_dsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,password,keyboard-interactive
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
Permission denied (publickey,password,keyboard-interactive).

ssh_config only defines how the ssh client acts; everything defined in ssh_config can be given as an argument to ssh. The really important configuration file is sshd.config (sshd is the ssh daemon, i.e. ssh server) on the machine being logged in to.

Using the 'ssh -vvv' will show all interactions between client and server, and will give some clues as to which, if any configuration items need to be changed in sshd.conf.
