In relation to this question. I wrote a response as well but I'll repost here, as not sure if that post will be read because of the date of the original post.
Each time I start a terminal session I have to first use ssh-add first to add the key; key being the id_rsa. Although in Windows rather command how do I use SSH-Agent as it doesn't exist in Windows so that I'm not prompt for the password for that terminal session ?
