SSH key on dreamhost

问题:

I am trying to setup an SSH key pairing with dreamhost and my local machine. I'm using git bash as my terminal (which uses mingw32)

I can ssh [e-mail] and I'm asked for my password. I have already created RSA keys on both my local and the shared dreamhost server. Here are the steps I take on my git terminal:

$ scp ~/.ssh/id_rsa.pub [e-mail]:~/

$ ssh [e-mail]
[e-mail]'s password: *****
$ (ls shows my local's id_rsa.pub in the ~ directory)
$ cd ~/.ssh
$ ls
id_rsa id_rsa.pub key_backup
$ cat ./id_rsa.pub >> authorized_keys (i know I could have just copied)
$ ls
authorized_keys id_rsa id_rsa.pub key_backup

vi authorized_keys shows my local's pubkey

$ chmod go-w ~
$ chmod 700 ~/.ssh
$ chmod 600 ~/.ssh/authorized_keys

I then exit the ssh connection and type ssh [e-mail] into my local shell

and I am asked for a password.... what am I doing wrong here?

do I need to setup ssh-agent? when i do, and try ssh-add I get 'could not open a connection to your authentication agent'

Thanks for any help!

EDIT: Here is a dump of ssh -v

I've had similar issue recently. Check permissions on server:

• ~/ (whole home directory) 755 or lower for group & others - this was cause of the issue for me I had 765
• ~/.ssh 700
• ~/.ssh/authorized_keys 600

Update:

There also can be issue with encryptfs, details here: https://serverfault.com/questions/310827/ssh-prompts-for-password-even-though-private-keys-are-available-presented-to-se/310829#310829
