1.错误信息
之前github都能用,但是今天git clone的时候居然连不上了,报错信息如下:
$ git clone git@github.com:hanchao5272/myreflect.gitCloning into 'myreflect'...ssh_dispatch_run_fatal: Connection to 13.250.177.223 port 22: Software caused connection abortfatal: Could not read from remote repository.Please make sure you have the correct access rightsand the repository exists.
2.错误分析
于是怀疑是连接不到github.com了,首先在cmd窗口中,尝试ping一下百度
C:\Users\hanchao>ping www.baidu.com正在 Ping www.a.shifen.com [61.135.169.121] 具有 32 字节的数据:来自 61.135.169.121 的回复: 字节=32 时间=24ms TTL=57来自 61.135.169.121 的回复: 字节=32 时间=45ms TTL=57来自 61.135.169.121 的回复: 字节=32 时间=26ms TTL=57来自 61.135.169.121 的回复: 字节=32 时间=22ms TTL=5761.135.169.121 的 Ping 统计信息:数据包: 已发送 = 4,已接收 = 4,丢失 = 0 (0% 丢失),往返行程的估计时间(以毫秒为单位):最短 = 22ms,最长 = 45ms,平均 = 29ms
说明网络连接正常。
然后再ping一下github.com
C:\Users\hanchao>ping github.com正在 Ping github.com [13.229.188.59] 具有 32 字节的数据:请求超时。请求超时。请求超时。请求超时。13.229.188.59 的 Ping 统计信息:数据包: 已发送 = 4,已接收 = 0,丢失 = 4 (100% 丢失),
3.错误解决
打开C:\Windows\System32\drivers\etc\hosts,内容如下:
# Copyright (c) 1993-2009 Microsoft Corp.## This is a sample HOSTS file used by Microsoft TCP/IP for Windows.## This file contains the mappings of IP addresses to host names. Each# entry should be kept on an individual line. The IP address should# be placed in the first column followed by the corresponding host name.# The IP address and the host name should be separated by at least one# space.## Additionally, comments (such as these) may be inserted on individual# lines or following the machine name denoted by a '#' symbol.## For example:## 102.54.94.97 rhino.acme.com # source server# 38.25.63.10 x.acme.com # x client host# localhost name resolution is handled within DNS itself.# 127.0.0.1 localhost# ::1 localhost0.0.0.0 account.jetbrains.com
发现:确实没有github.com的解析
在文件末尾添加如下内容,并保存:
192.30.255.112 github.com git185.31.16.184 github.global.ssl.fastly.net
重启cmd窗口,继续ping一下github.com:
正在 Ping github.com [192.30.255.112] 具有 32 字节的数据:来自 192.30.255.112 的回复: 字节=32 时间=311ms TTL=48来自 192.30.255.112 的回复: 字节=32 时间=365ms TTL=48来自 192.30.255.112 的回复: 字节=32 时间=376ms TTL=48来自 192.30.255.112 的回复: 字节=32 时间=353ms TTL=48192.30.255.112 的 Ping 统计信息:数据包: 已发送 = 4,已接收 = 4,丢失 = 0 (0% 丢失),往返行程的估计时间(以毫秒为单位):最短 = 311ms,最长 = 376ms,平均 = 351ms
- 说明,本机已经能够正常解析
github.com这个域名了。至此,问题解决
