lsyncd error: unexplained error (code 255) at io.c(235) [sender=3.1.2]的解决方法

首先贴一下lsyncd的配置文件

settings {
   logfile    = "/tmp/lsyncd.log",
   statusFile = "/tmp/lsyncd.status",
   insist = true,
   statusInterval = 10
}
sync {
    default.rsyncssh,
    source    = "源服务器路径",
    host      = "目标服务器IP",
    targetdir = "目标服务器路径",
    -- maxDelays = 5,
   delete = false,
   delay = 30,
    -- init = false,
    rsync    = {
        binary = "/usr/bin/rsync",
        archive = true,
        compress = true,
        verbose   = true,
        owner = true,
        perms = true,
       
        },
}

今天出现了 syncd error: unexplained error (code 255) at io.c(235) [sender=3.1.2]错误

解决方法，编辑ssh的配置文件

/etc/ssh/sshd_config

添加以下代码，，，目的是解决lsyncd同步大文件时的超时问题，

ClientAliveInterval 30
ClientAliveCountMax 6
