综合结构错误集合

1.not a regular file 不是普通文件

scp默认只能复制普通文件 与cp类似
加上-r 即可

[root@backup ~]# scp /etc/  172.16.1.31:/tmp
[email protected]'s password: 
/etc: not a regular file

2.remote command not found

远程服务器中没有这个命令
检查远程服务器是否安装了rsync 没有yum安装即可

[root@backup ~]# rsync -av /etc 172.16.1.31:/tmp
[email protected]'s password: 
bash: rsync: command not found
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: remote command not found (code 127) at io.c(226) [sender=3.1.2]

3.Connection refused

连接拒绝
检查是否能ping通对应服务器

  [root@backup ~]# rsync -avz /etc 176.16.1.31:/tmp
ssh: connect to host 176.16.1.31 port 22: Connection refused
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(226) [sender=3.1.2]

4. auth failed on module datadata

模块 认证错误(密码)

@ERROR: auth failed on module data
rsync error: error starting client-server protocol (code 5) at main.c(1648) [sender=3.1.2]

5. secrets file

nfs

mount: wrong fs type, bad option, bad superblock on 172.16.1.31:/data,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount. helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

No route to host

没有路由,道路不通。
