使用debug1: Trying private key: /c/Users/29676/.ssh/id_dsa提示的文件名id_dsa
gitee是可以正常访问的

然后

$ ssh -T git@github.com
Hi xsxiaosheng! You've successfully authenticated, but GitHub does not provide shell access.

gitee、github两套ssh共存

  • 首先进入C:/USER/XXX/.ssh

  • 执行

ssh-keygen -t rsa -C "2967615343@qq.com" -f "github_id_rsa"
ssh-keygen -t rsa -C "2967615343@qq.com" -f "gitee_id_rsa"

  • 创建known_hosts文件
    打开,填入
# gitee
Host gitee.com
HostName gitee.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/gitee_id_rsa

# github
Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/github_id_rsa
  • 测试
ssh -T git@github.com
ssh -T git@gitee.com

注意

Hi xsxiaosheng! You've successfully authenticated, but GitHub does not provide shell access.

这样提示是正常的,这样的意思就是,你可以访问,但是不能给你提功ssh登录权限
