Git - 解决Github连接失败的问题

Github有时会出现突然连接失败的问题，有部分情况是地址解析错误导致的，本文介绍此类问题的解决方案。

问题复现

Github本来好好的，说不定啥时候就会报错，报错信息如下：

Connection to XXXXX port 22: Software caused connection abort
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

此问题也会导致 Hexo 在 hexo d 过程中报错：

ssh_dispatch_run_fatal: Connection to 13.250.177.223 port 22: Broken pipe
fatal: sha1 file '<stdout>' write error: Broken pipeiB/s
fatal: the remote end hung up unexpectedly
fatal: the remote end hung up unexpectedly

错误原因

• 网络不通
• 本地DNS无法正确解析地址

解决方案

打开C:\Windows\System32\drivers\etc\hosts文件：

# 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             localhost

在最后加入内容：

192.30.255.112  github.com git 
185.31.16.184 github.global.ssl.fastly.net  12

• 至此问题解决，github可以正常访问。
