本文解决了一个常见的技术问题：重装系统后，使用git push和ssh登录远程服务器时遇到的链接失败问题。通过调整MTU（最大传输单元）设置，成功解决了这一难题。文章详细记录了故障排查过程及解决方案。

重装系统后git push和ssh登录远程服务器一直链接失败，重装系统前没发现这毛病。

后来ssh -v 登录查看了下日志，发现一直卡在debug1: SSH2_MSG_KEXINIT sent。直到最后链接失败。

网上查了很多，发现是因为mtu设置的数值太大。

详情参考 https://blog.youkuaiyun.com/wjciayf/article/details/76916075

http://techbackground.blogspot.com/2013/06/path-mtu-discovery-and-gre.html

之后开始设置mtu数值

 

 

 将“硬件”中的配置由“自动”变为“手动”，mtu设置为标准。之后就可以了

最近我在尝试从一台linux服务器SSH登录到另一台服务器时发现链接错误。通过加入-vvv参数后，发现卡在debug1: SSH2_MSG_KEXINIT sent 通过搜索，发现可能是网络接口MTU设置的问题。我尝试在/etc/sysconfig/network-scripts/ifcfg-eth0中添加MTU=1500，在重启网络服务后，发现并没有生效。由于我是通过DHCP获取IP地址的，那么...
