解决 GitHub Connect: kex_exchange_identification: Connection closed by remote host 作者: Chuwen 时间: 2022-07-30 分类: Linux 评论 # 背景 想要克隆项目/推送代码到 GitHub 老实错误，检查发现： ```shell ➜ ~ ssh -vvv git@github.com OpenSSH_8.1p1, LibreSSL 2.7.3 debug1: Reading configuration data /Users/chuwen/.ssh/config debug1: /Users/chuwen/.ssh/config line 1: Applying options for * debug1: /Users/chuwen/.ssh/config line 6: Applying options for github.com debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 47: Applying options for * debug1: Executing proxy command: exec nc -v -x 127.0.0.1:7890 github.com 443 debug1: identity file /Users/chuwen/.ssh/id_rsa type 0 debug1: identity file /Users/chuwen/.ssh/id_rsa-cert type -1 debug1: identity file /Users/chuwen/.ssh/id_dsa type -1 debug1: identity file /Users/chuwen/.ssh/id_dsa-cert type -1 debug1: identity file /Users/chuwen/.ssh/id_ecdsa type -1 debug1: identity file /Users/chuwen/.ssh/id_ecdsa-cert type -1 debug1: identity file /Users/chuwen/.ssh/id_ed25519 type -1 debug1: identity file /Users/chuwen/.ssh/id_ed25519-cert type -1 debug1: identity file /Users/chuwen/.ssh/id_xmss type -1 debug1: identity file /Users/chuwen/.ssh/id_xmss-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_8.1 Connection to github.com port 443 [tcp/https] succeeded! kex_exchange_identification: Connection closed by remote host ``` # 解决方案 最后找到[一篇文章](https://idreamshen.github.io/posts/github-connection-closed/ "一篇文章")解决了这个问题。 只需要在 `~/.ssh/config` 配置以下项目即可 ```config Host github.com HostName ssh.github.com User git Port 443 ``` 如果想要配置代理可以这样： ```config Host github.com HostName ssh.github.com User git Port 443 # 走 HTTP 代理 # ProxyCommand socat - PROXY:127.0.0.1:%h:%p,proxyport=8080 # 走 socks5 代理（如 Shadowsocks） ProxyCommand nc -v -x 127.0.0.1:7890 %h %p ``` ## 最终解决了问题 ```shell ➜ ~ ssh -T git@github.com Connection to ssh.github.com port 443 [tcp/https] succeeded! Hi PrintNow/react-i18next-base-usage! You've successfully authenticated, but GitHub does not provide shell access ```
