雙臺服務器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）
另一臺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服務端服務器121.15.1.102上的配置文件rsyncd.conf
一開始/etc/rsyncd.conf 裏面配置的允許ip:為61.10.45.70
[[email protected] 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機器推送數據到121.15.1.102機器上）
[[email protected] 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在同步中兩臺服務器的網卡尋找線路是聯通找聯通，電信的找電信的，而上面個的配置文件中添加的是的電信的ip地址：61.10.45.70，這樣會導致61.10.45.70機器進行rsync傳順數據包到121.15.1.102機器上出問題，
於是把上面的rsyncd.conf配置文件中的 地址改為112.82.223.70（聯通ip）就沒問題了
解決上面的問題是從報錯日誌文件中發現:
tail -100f /var/log/rsyncd.log
