之前用的好好的,包括我其他 git 平台 ssh 都是正常使用,只有 github 不行. 尝试删除.ssh 里所有文件重新生成 ssh key,重新上传 github 还是不行,其他 git 平台上传后就正常使用了现在是我自己 github 仓库代码都没拉取了. 执行

ssh -vT [email protected]

结果

ssh -vT [email protected]

解决了 host 里面配上 140.82.114.4 github.com,然后删掉.ssh下面的known_hosts文件,我今天最初发现的报错就是如下报错,然后我就做了重新生成ssh操作,谢谢各位,还有评论区有位兄弟说是湖北电信dns劫持问题,我觉得可信,我就是湖北电信

现在我又去路由里面改了 dns ,这样是最简单的解决办法,而且同事的都好了

最后要我输入密码怎么输入都是报 Permission denied, please try again.

github 有自己的 cli 验证，https://cli.github.com/ ，建议用这个验证。

我猜是 macOS Monterey Beta 版出现的问题🤔要是临时用的话可以 git remote add https ______https__repo__url 然后直接 git push https 上传，目前还没解决这个问题

luvxy

2022-09-21 17:20:38 +08:00

@EZ4ZZW 不是这个问题, 我执行的是 ssh -vT [email protected] 。还没有去拉仓库代码 ,不过这两方式结果一样

2022-09-21 17:49:13 +08:00

@luvxy 我刚才找到了一个解决方案，把 ssh 改成 ssh over https ，可以解决这个问题，但是还没发现实质问题在哪里。https://docs.github.com/en/authentication/troubleshooting-ssh/using-ssh-over-the-https-port

你试试解决一开始的报错

debug1: Reading configuration data /Users/dzjhack/.ssh/config
debug1: /Users/dzjhack/.ssh/config line 1: Applying options for *
/Users/dzjhack/.ssh/config line 4: Unsupported option "rsaauthentication"

尝试 follow 这份文档重新添加 key 试试

[GitHub's SSH key fingerprints - GitHub Docs]( https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/githubs-ssh-key-fingerprints)

我草率地看了下，大概是因为你连到的服务器不是 GIthub 的。可能被劫持了。

我用你执行的命令试了下，其中这行你的和我的不一样：

```
debug1: Server host key: ssh-rsa SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8
```

建议重新生成一次密钥对。。。然后执行：

```
ssh-keygen -R github.com
```

看清楚服务器指纹是否正确，正确了同意连接。

和我昨天遇到的情况一模一样，连这个都一样。
改了下 github 的 hosts 就可以了。
湖北？今天在 v2 看到说湖北电信 github 的 dns 被污染了，不知道是否有关系

luvxy

2022-09-21 18:12:59 +08:00

@thefck 是湖北电信。我擦我也就是改 hosts 好了

国内运营商连 Github 都要污染吗？本人 Github 相关域名常年走软路由，居然没有发现问题~

2022-09-21 18:22:12 +08:00

~/.ssh/config Windows 下

Host github.com
HostName ssh.github.com
Port 443
User git
ProxyCommand connect -S 127.0.0.1:1080 -a none %h %p

Host *
IdentityFile "C:\Users\<user>\.ssh\id_rsa"
ServerAliveInterval 30
TCPKeepAlive yes

湖北移动也碰到这个问题了，用了楼主该 hosts 方式解决了

HuangLibo

2022-10-05 17:26:51 +08:00

湖北联通也遇到了这个问题，我是通过把默认 DNS 改成 114DNS 解决的。楼上说的改 host 应该也是可以的，一样的原理，DNS 被运营商劫持了。

同湖北电信, 俺最近几天也遇到这个问题了

SHA256:rEmlJenVMSL5GVemSY0Gk8WGw6B4ege4J85M+vup8R0 这个 fingerprint 有问题, 不属于 https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/githubs-ssh-key-fingerprints 中列举的.
应该是 dns 污染了
修改 host 的方法好使
