今天早上天天连接的开发机突然报出连接错误。

这个错误是SSH最常见错误,造成的原因也是千奇百怪(具体可goole),下面描述我的server的问题:

客户端报错

[root@server]# ssh 192.168.1.22
Read from socket failed: Connection reset by peer

换个机器连接也不行,尝试重启server端的sshd,thanks god, 报错了

[root@GMTDev ssh]# service sshd restart
Stopping sshd: [ OK ]
Starting sshd: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

先解决这个错误吧

chmod 600 /etc/ssh/*key*

service sshd restart

按理说,只有我自己用这个机器,不知道为什么权限莫名报错。
