原因:
1.公司屏蔽了端口22的访问,检测一下端口22是否能够链接?
2.本机防火墙的缘故而不能使用端口22?
PowerShell 版本是5及其以后,直接使用命令Get-NetTCPConnection参看与端口相关的信息
PS C:\> $PSVersionTable Name Value ---- ----- PSVersion 5.1.14393.693 PSEdition Desktop PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...} BuildVersion 10.0.14393.693 CLRVersion 4.0.30319.42000 WSManStackVersion 3.0 PSRemotingProtocolVersion 2.3 SerializationVersion 1.1.0.1 PS C:\> Get-NetTCPConnection -LocalPort 80 | Format-Table -Property LocalAddress, LocalPort, State, OwningProcess LocalAddress LocalPort State OwningProcess ------------ --------- ----- ------------- :: 80 Listen 4
使用命令use Test-NetConnection测试远程主机的端口
PS C:\> Test-NetConnection -ComputerName 10.216.25.35 -Port 443 -InformationLevel Detailed
ComputerName : 10.216.25.35
RemoteAddress : 10.216.25.35
RemotePort : 443

如果是公司屏蔽端口访问,则使用http进行访问,对于git的url进行覆写。
git config --global url."https://".insteadOf git://
git config --list
~/.gitconfig 文件中可以看到:
[url "https://"]
insteadOf = git://
先测试443能不能用?
$ ssh -T -p 443 git@ssh.github.com
> Hi username! You've successfully authenticated, but GitHub does not
> provide shell access.
~/.ssh/config文件下设置:
Host github.com
Hostname ssh.github.com
Port 443
测试是否设置成功
$ ssh -T git@github.com
> Hi username! You've successfully authenticated, but GitHub does not
> provide shell access.
