Ubuntu和FreeBSD之间的rsync

我正在尝试在我家的Ubuntu 14.04 i686服务器（备份存储）和被监禁的FreeBSD 10.3-PRERELEASE#5 amd64（web服务器）之间同步文件

我使用以下命令（真正的IP肯定是另一个）：

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，我会得到以下结果

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]

谢谢你的建议。

解决了。原因是FreeBSD监狱配置。采取了哪些措施来解决问题：

• 在主机FreeBSD机器上：在

  /etc/sysctl.conf

  set中

  net.inet.tcp.tso=0

• 入狱：在

  /etc/ssh/sshd_config

  add

  UsePAM yes

• 然后更新监狱中的所有内容，使其与主机FreeBSD上的版本相同

这只是一个不太了解rsync的人的想法。FreeBSD对文件具有附加的用户权限，这些文件称为“标志”。这可能会导致您的问题。我要做的是尝试与同一台主机同步（例如QEMU上的FreeBSD FreeBSD），然后继续查看FreeBSD->Ubuntu的情况。这是一个不太懂rsync的人的想法。FreeBSD对文件具有附加的用户权限，这些文件称为“标志”。这可能会导致您的问题。我要做的是尝试与同一主机同步（例如QEMU上的FreeBSD FreeBSD），然后继续查看FreeBSD->Ubuntu的情况。
