图片保存到liunx失败

解决方法：

Linux修改SSH连接数 重启SSH服务

系统 linux，增加SSH终端连接数最大为1000个


解决方案：


vi /etc/ssh/sshd_config


输入/MaxStartups 定位到如下并修改


1)        #MaxStartups 10，#去掉，修改10为1000，MaxStartups 1000


2)        重启SSH服务，/etc/rc.d/init.d/sshd restart


 


查看某端口连接数


 netstat -nat|grep -i '22' |wc -l

解决结果：

连续测了5、6天没出现什么问题，后来该故事就关闭了。。
