1.Linux系统中scp命令传输文件报错显示
ssh_exchange_identification: read: Connection reset by peer
lost connection
以为是ssh连接有问题,查了半天ssh连接问题,后来发现是映射文件IP写错了
特此记录
2.虚拟机ping主机和外网突然ping不通,找不到原因,最后发现是NetworkManager没有关,特此记录
systemctl status NetworkManager //查看状态
此处是否是关闭状态,如果不是:
[atguigu@hadoop102 ~]$ systemctl stop NetworkManager //关闭网络管理
[atguigu@hadoop102 ~]$ systemctl disable NetworkManager //设施开机不自启
3.查看防火墙 //简单记录,提醒下次创建虚拟机时不要忘记
4.改静态IP地址
