Question

我正在尝试在我的家庭Ubuntu 14.04 i686服务器（这是备份存储）之间rsync文件并且将FreeBSD 10.3-PRERELEASE＃5 amd64（这是web服务器）监禁。

我使用以下命令（真正的IP肯定是另一个）：

rsync -uvrhtl --delete-after -e="ssh -l user -p 2222" 8.8.8.8:/hosting/my.site /backup/my.site

我得到以下错误：

Password for user@example.com:
receiving file list ... Connection to 8.8.8.8 closed by remote host.
rsync: connection unexpectedly closed (16384 bytes received so far) [Receiver]
rsync error: unexplained error (code 255) at io.c(226) [Receiver=3.1.1]

同时scp工作正常：

$ scp -P 2222 user@8.8.8.8:/hosting/my.site/index.php /backup/my.site/
Password for user@example.com:
index.php
$ ls /backup/my.site/index.php
-rw-r--r-- 1 user user 418 Jan 25 17:00 /backup/my.site/index.php

如果我尝试在FreeBSD上做同样的事情，我会跟随

rsync -uvrhtl user@home.com:/backup/my.site ~/tmp/
user@home.com's password: 
receiving incremental file list
created directory /home/user/tmp
./
site-folders-and-files/
...

...
site-folders-and-files/folders/folders/README
Write failed: Permission denied
rsync: connection unexpectedly closed (58914 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(226) [receiver=3.1.1]
rsync: connection unexpectedly closed (67040 bytes received so far) [generator]
rsync error: error in rsync protocol data stream (code 12) at io.c(226) [generator=3.1.1]

解决。原因在于FreeBSD jail配置。如何解决问题：

：在/etc/sysctl.conf集中 net.inet.tcp.tso=0
在监狱中：/etc/ssh/sshd_config添加UsePAM yes
然后将jail中的所有内容更新为与主机FreeBSD相同的版本
