ssh bitbucket.org by GitBash

//=== https://confluence.atlassian.com/display/BITBUCKET/Set+up+SSH+for+Git

0. launch GitBash
1. chk OpenSSH/OpenSSL are installed
$ ssh -v
   OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 ...

$ cd    //go back user home folder
$ pwd
$ cd .ssh
[ $ cd ~/.ssh ]


$ ls
id_rsa    id_rsa.pub  known_hosts

* id_rsa is the private key
* id_rsa is the public key
* id  --> identifier for short

2. $ ssh-keygen

[ 3.  notepad ~/.ssh/config , 預設的組態檔
加入
Host bitbucket.org
 IdentityFile ~/.ssh/id_rsa

"...
The second line is indented.
That indentation (a single space) is important, so make sure you include it.
..."
IdentityFile 的那一行開頭必須有一個空白, 之後緊接著IdentityFile  path-to-privatekey

]

4.  $ ssh-add -l
Could not open a connection to your authentication agent
-->
need to start ssh-agent before you run the ssh-add command:

$ eval `ssh-agent -s`  # need to use eval instead of just ssh-agent
$ ssh-add path-to-target-privatate-key

path-to-target-privatate-key 代表密鑰檔案路徑
會蓋過預設組態檔的設定
[例] /c/myProjs/sshkeys/privkey-for-bitbucket

5. 將公鑰(.pub)內容複製到 bitbucket.org 帳戶
account settings --> ssh
*** take care not to wrap the lines


6. 更改既存的git config, 將https改為ssh
$ cat .git/config
[core]
  ...
[remote "origin"]
  fetch = +refs/heads/*:refs/remotes/origin/*
  url = https://username@bitbucket.org/teamid/repo1.git
[branch "master"]
  remote = origin
  merge = refs/heads/master

--> url = ssh://git@bitbucket.org/username/repo1.git

https://accountname@bitbucket.org/accountname/reponame.git
-->  ssh://git@bitbucket.org/accountname/reponame.git

https://accountname@bitbucket.org/teamid/reponame.git
-->  ssh://git@bitbucket.org/teamid/reponame.git


//=== 讓 Git Bash 啟動時帶入 ssh-agent
http://stackoverflow.com/questions/17846529/could-not-open-a-connection-to-your-authentication-agent

1. notepad .bashrc

#!/bin/bash
eval `ssh-agent -s`
ssh-add

ssh-add without paramaters
-->  ~/.ssh/id_rsa

for customized location of the private key
--> ssh-add path-to-private-key


2. Restart GitBash (Msysgit)

//=== ssh-add, ssh-agent
$ man ssh-add
""" ...
-L      Lists public key parameters of all identities currently repre?
             sented by the agent.

-l      Lists fingerprints of all identities currently represented by the
             agent.
... """

$ man ssh-agent
""" ...
     a program to hold private keys used for public key authenti?
     cation (RSA, DSA, ECDSA).  The idea is that ssh-agent is started in the
     beginning of an X-session or a login session, and all other windows or
     programs are started as clients to the ssh-agent program.  Through use of
     environment variables the agent can be located and automatically used for
     authentication when logging in to other machines using ssh(1).
