升级到 Catalina (MAC OS) 后无法访问 github

Question

我升级了 Catalina，然后我无法访问我的 github 存储库：

$ ssh -T git@github.com
kex_exchange_identification: Connection closed by remote host

$ ssh -vvv git@github.com
OpenSSH_8.1p1, LibreSSL 2.7.3
debug1: Reading configuration data /Users/XXX/.ssh/config
debug1: /Users/XXX/.ssh/config line 1: Applying options for *
debug1: /Users/XXX/.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: Connecting to ssh.github.com port 443.
debug1: Connection established.
debug1: identity file /Users/XXX/.ssh/id_rsa type 0
debug1: identity file /Users/XXX/.ssh/id_rsa-cert type -1
debug1: Local version string SSH-2.0-OpenSSH_8.1
kex_exchange_identification: Connection closed by remote host

这曾经工作得很好。知道如何调试吗？

Answer 1

Connecting to ssh.github.com port 443

这意味着你是Using SSH over the HTTPS port

试试测试：

ssh -Tv -p 443 git@ssh.github.com

但仔细检查端口 22 是否被阻止：

ssh -T -p 22 git@github.com

如果仍然失败，请查看“The hard way to debug the mysterious git+ssh+proxy failure “bash: No such file or directory””

解决方案：手动将 SHELL 设置为 shell 的完整路径名，例如/bin/bash.
