雙台伺服器rsync同步報錯(code 5) at main.c(1503) [sender=3.0.6]

環境：某某項目的代碼機器70配置有雙網卡：232.182.23.70（聯通）61.10.45.70（電信）

另一台代碼機器是滄州聯通的代碼機器102，配置單網卡：121.15.1.102（聯通）

rsync服務端伺服器121.15.1.102上的配置檔案rsyncd.conf

一開始/etc/rsyncd.conf 裡面配置的允許ip:為61.10.45.70

[root@localhost tmp]# cat /etc/rsyncd.conf 

##rsyncd.conf start##

uid = root

gid = root

port=873

use chroot = no 

read only = no 

list = no 

max connections = 200

timeout = 300

auth users = stuser

hosts allow =  61.10.45.70

#hosts deny = *

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsync.lock

log file = /var/log/rsyncd.log

secrets file = /etc/rsync.pass

motd file = /etc/rsyncd.Motd

[sdkdhcode]

path = /data/www/sdkdhcode/

comment = sdkdhcode

看似一切正常，但是這樣在配置好的rsync的同步環境就出問題了：

（61.10.45.70機器推送資料到121.15.1.102機器上）

[root@localhost tmp]# rsync -avH --port=873 --progress  /opt/biao-framedb_backup.sh  [email protected]::sdkdhcode --password-file=/tmp/lmpasswd.txt 

@ERROR: Unknown module 'sdkdhcode'

rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]

原因是：rsync在同步中兩台伺服器的網卡尋找線路是聯通找聯通，電信的找電信的，而上面個的配置檔案中添加的是的電信的ip位址：61.10.45.70，這樣會導緻61.10.45.70機器進行rsync傳順資料包到121.15.1.102機器上出問題，

于是把上面的rsyncd.conf配置檔案中的 位址改為112.82.223.70（聯通ip）就沒問題了

解決上面的問題是從報錯日志檔案中發現:

tail -100f /var/log/rsyncd.log
