rsync 客戶端同步的時候報錯

已經做過好幾臺伺服器的rsync配置了，可是有遇到了一個怪異的問題

rsync客戶機同步的時候報錯：
[root@tonykorn02 test]# /usr/bin/rsync -vzrtopg --progress --delete 192.168.1.250::test /test
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(463) [receiver=2.6.8]

原來的版本：
[root@tonykorn test]# rpm -e rsync-2.6.8-3.1
warning: /etc/xinetd.d/rsync saved as /etc/xinetd.d/rsync.rpmsave

新安裝的版本，
[root@tonykorn installfiles]# rpm -ivh rsync-2.6.3-1.x86_64.rpm
warning: rsync-2.6.3-1.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID db42a60e

因為在redhat4u4上面同樣的配置都可以執行，所以用redhat4u4中的rsync版本試試，更換服務端rsync版本還是一樣的報錯：

重啟xinetd服務，檢視日誌資訊：
May 15 12:54:57 tonykorn xinetd[7308]: Exiting...
May 15 12:54:57 tonykorn xinetd[16450]: bind failed (Address already in use (errno = 98)). service = rsync
May 15 12:54:57 tonykorn xinetd[16450]: Service rsync failed to start and is deactivated.
May 15 12:54:57 tonykorn xinetd[16450]: xinetd Version 2.3.14 started with libwrap loadavg labeled-networking options compiled in.
May 15 12:54:57 tonykorn xinetd[16450]: Started working: 2 available services

檢視埠的使用情況：
[root@tonykorn posftp]# netstat -na | grep 873
tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN
[root@tonykorn posftp]#

停止掉xinetd後檢視埠的佔用狀態：
[root@tonykorn xinetd.d]# /etc/init.d/xinetd status
xinetd (pid 16964) is running...
[root@tonykorn xinetd.d]# /etc/init.d/xinetd stop
Stopping xinetd: [ OK ]
[root@tonykorn xinetd.d]# netstat -na | grep 873
tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN
unix 3 [ ] STREAM CONNECTED 76873
[root@tonykorn xinetd.d]#

檢視那個程式在使用這個埠：
[root@tonykorn xinetd.d]# netstat -lnp
Active Internet connections (only servers)

tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 2772/portmap

查詢那個程式啟動的這個埠，關閉這個服務
[root@tonykorn xinetd.d]# chkconfig --list | grep nfs
nfs 0:off 1:off 2:off 3:off 4:off 5:off 6:off
nfslock 0:off 1:off 2:off 3:on 4:on 5:on 6:off
[root@tonykorn xinetd.d]# service nfslock status
rpc.statd (pid 2811) is running...
[root@tonykorn xinetd.d]# service nfslock stop
Stopping NFS statd: [ OK ]
[root@tonykorn xinetd.d]# netstat -lnp | grep 873
[root@tonykorn xinetd.d]# netstat -na | grep 873
[root@tonykorn xinetd.d]#

重新啟動xinetd服務
[root@tonykorn xinetd.d]# /etc/init.d/xinetd start
Starting xinetd: [ OK ]
[root@tonykorn xinetd.d]# vi /var/log/messages

May 15 13:27:50 tonykorn rpc.statd[2811]: Caught signal 15, un-registering and exiting.
May 15 13:28:52 tonykorn xinetd[18304]: xinetd Version 2.3.14 started with libwrap loadavg labeled-networking options compiled in.
May 15 13:28:52 tonykorn xinetd[18304]: Started working: 3 available services

從日誌上可以看到伺服器已經啟動。

重新執行rsync成功
[root@tonykorn02 test]# /usr/bin/rsync -vzrtopg --progress --delete 192.168.1.250::test /test
