无法通过ssh连接到github [英] can't connect to github via ssh
问题描述
我试图从我新安装的使用fluxbox运行manjaro的Linux机器上克隆我的一个github仓库。我设置了user.name和user.email并上传了正确的ssh密钥。但我总是得到
主机'github.com（192.30.252.129）'的真实性无法建立。
RSA密钥指纹是SHA256：nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8。
您确定要继续连接（是/否）吗？
主机密钥验证失败。
致命：无法从远程存储库读取。
请确保您拥有正确的访问权限并存在存储库。
我搜索了它，发现我应该做 ssh-keygen -R github .com 这应该从我的known_hosts文件中删除github，但known_hosts文件还没有存在，因为我刚刚完成了一个新的linux安装。
所以我试过 ssh -vT git @ github 这给了我
ssh -vT git@github.com

这是我的头脑。有人可以告诉我出了什么问题，也许该如何解决这个混乱问题？
解决方案您是否尝试将github添加为已知主机？
如果您有一个现有的 known_hosts 文件并且不想覆盖（如评论中建议的@Puce） ，使用它。
ssh-keyscan -t rsa github.com>> 〜/ .ssh / known_hosts
这会将rsa密钥添加到known_hosts的末尾。 p>
如果您不知道 known_hosts 是/是否意味着，或者您从来没有使用它，那么您可以简单地写一个新的，但注意，这将删除现有的一个，如果你有任何。
ssh-keyscan -t rsa github。 com> 〜/ .ssh / known_hosts
I tried to clone one of my repositories on github from my newly installed linux machine running manjaro with fluxbox. i set up the user.name and user.email and uploaded the correct ssh key. but i always get
The authenticity of host 'github.com (192.30.252.129)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)?
Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
I googled it and found that i should do ssh-keygen -R github.com which should delete github from my known_hosts file but the known_hosts file doesn't even exist yet, because i just finished setting up a new linux install.
so i tried ssh -vT git@github which gave me
ssh -vT git@github.com

which is way over my head. can somebody tell me what went wrong and maybe how to fix this mess?
Did you try to add github as known host?
If you have an existing known_hosts file and do not want to overwrite (as @Puce suggested in the comment), use this.
ssh-keyscan -t rsa github.com >> ~/.ssh/known_hosts
This will add the rsa key to the end of the known_hosts.
If you have no idea what known_hosts is/means, or you never engaged with it for sure, you can simply write a new one, but note that this will remove the existing one if you had any.
ssh-keyscan -t rsa github.com > ~/.ssh/known_hosts
