通过控制台从本地登录服务器,使用last指令查看登录情况,发现好几个终端依然登着,但是ip地址变化了,好吧,很有可能是网络ip地址变化导致xshell自动断开连接。于是修改本机ip为固定地址发现就不会轻易断了。

本人修改本机IP为固定地址了,还是不能解决问题。继续经过多次BAIDU和艰苦摸索,终于找到了解决办法:
一、修改配置文件:
如果本机网络dns变化也会导致xshell自动断开连接,这种情况通过修改ssh配置文件将其中“UseDNS yes”去掉注释并改成no即可,过程如下。
vim /etc/ssh/sshd_config将UseDNS yes 改为 no,保存。
UseDNS no二、重新更改ssh配置目录和文件的权限(为了安全系统配置文件勿随意开放为所有权限)
cd /etc/sshsudo chmod 644 ./*
sudo chmod 600 ssh_host_dsa_key
sudo chmod 600 ssh_host_rsa_key
sudo chmod 755 .
修改完配置记得重新启动ssh
/etc/init.d/sshd restart三、也有网友把权限设置为如下样子也可以了的
- 修改ssh权限
chmod 400 /etc/ssh/* - 重启SSH
service sshd restart - 重启网关
service network restart
四、没有设置超时时间
解决方案是:
sudo vim /etc/ssh/sshd_config添加两行:
ClientAliveInterval 60ClientAliveCountMax 3
然后
sudo /etc/init.d/sshd restart 标签:09,Connection,etc,host,ssh,Linux,pts,连接,SSH From: https://www.cnblogs.com/wjsqqj/p/16984532.html
