求助 SSH -vT [email protected] 命令报错

在使用ssh命令测试能否登陆github服务器的时候出现Permission deny，麻烦各位给分析分析是啥原因

找不到private key..

把private key命名为id_rsa, 放在$HOME/.ssh/试一试

[vitozhang]

初步确定问题出在
debug1: identity file /.ssh/identity type -1
debug1: identity file /.ssh/id_rsa type -1
debug1: identity file /.ssh/id_dsa type -1
系统找不到路径 /.ssh/
这是什么原因呢

[vitozhang]

@paulw54jrn 忘了跟你说了，我的是win8系统，private key已经放到 用户名/.ssh 目录了

@vitozhang
Windows下不熟悉.. 你是在Cygwin里面ssh的妈?

[paulw54jrn]

根据http://weka.wikispaces.com/Where+is+my+home+directory+located%3F

on Windows, open a command-prompt and type the following command
echo %USERPROFILE%
on Cygwin, open a bash and type the following command
echo $USERPROFILE

如果是Cygwin的话, 放在 $USERPROFILE/.ssh/ 试试

到 git 安装目录下去找 ssh_config 这个文件（一般是 /etc/ssh 下面），改成
IdentityFile=~/.ssh/id_rsa
注意有个 ~

[Ge4Los]

如果用cygwin的话, 先要在环境变量里面先定义下HOME
然后把id_rsa 放在 ~/.ssh/ 的目录下

我使用的MinGW，不过跟这个没关系，Git安装目录自带了个ssh以及.ssh目录，我把系统用户名目录下的.ssh 的内容拷贝到Git安装目录下的.ssh中就可以了。不过我还是没找到ssh_config文件，不知道该怎么设置ssh命令默认的private key的存放位置。

[aa65535]

@vitozhang Ctrl + F 搜索一下，一般是在 Git 安装目录 下的 etc/ssh 中，或者 MinGW 下的 etc/ssh 中，没有可以新建一个。
Host *
  StrictHostKeyChecking no
  UserKnownHostsFile=/dev/null
  IdentityFile=~/.ssh/id_rsa

可以在 http://git-scm.com/downloads 下载一个， 也是 MinGW 的。

[vitozhang]

@aa65535 在Git安装目录下的etc/ssh目录中添加了ssh_config文件， 并添为所有Host添加IdentityFile=~/.ssh/id_rsa
但ssh依然将路径解释为 /.ssh/id_rsa，完全忽略了~。
添加环境变量 HOME，设置为C:/Users/myname，然后将设置身份文件为IdentityFile=$HOME/.ssh/id_rsa发现奏效。另外，如果发现直接设置绝对路径/c/Users/myname/.ssh/id_rsa也是可以的。
