I understand it wrongly first. Try first

export DISPLAY=:0

And run your ssh, this might help.

Associating ssh public key with user account

First, you create a public and private key (if you haven't done so already) on the machine from which you want to login:

ssh-keygen -t dsa

You only need to do this if there isn't already a ~/.ssh/id_dsa.pub file.

On Linux, there's the ssh-copy-id helper. On Mac, you need to copy the public key by hand:

Copy the generated public key to the target machine:

scp ~/.ssh/id_dsa.pub user@targetmachine:myPublicKey.pub
Login to the target machine:

ssh user@targetmachine
Append the public key to the authorized keys:

cat myPublicKey.pub >>.ssh/authorized_keys
You can now delete the copied key:

rm myPublicKey.pub
Done. You should now be able to login to your target machine without the need to enter a password.

MacOS – ssh terminal window closes immediately when opened

Here's what happened. On the machines I was trying to reach (10.x.y.182 and 10.x.y.194), in the time when I was not using them they had their hard disks replaced and the OS reinstalled. This gave them new SSH keys, invalidating the ones I had in my ~/.ssh/known_hosts file. Unfortunately, Terminal.app did not surface this problem to me.

By deleting the entries for those machines in ~/.ssh/known_hosts, I forced the system to pull down the new keys and ask me if I wanted to use them. With this done, connections worked perfectly as usual. Oddly, however, even before I changed ~/.ssh/known_hosts, connections using the DNS name of the machine (svr10 and svr20) worked. Weird.

Thanks, everyone, who looked at this problem.
