我刚刚在Debian框中安装了BackupPC,将其用作备份服务器.如
你知道,这个软件可以使用rsync等.使用时
rsync选项,它失败了.
你知道,这个软件可以使用rsync等.使用时
rsync选项,它失败了.
>服务器:Debian Jessie. BackupPC 3.3.1从源代码构建,由执行
用户“backup-user”. Rsync 3.1.2使用默认值从源代码构建
选项.
>客户:Debian Jessie. Rsync 3.1.2使用默认值从源代码构建
选项.
失败后,可以在BackupPC的日志中找到使用的rsync命令.
在shell中尝试命令,以BackupPC用户身份登录,我遇到了这个问题
“协议版本不匹配 – 你的shell干净了吗?”错误.命令是:
/usr/bin/ssh -q -x -l backup-user 192.168.10.20 /usr/local/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --ignore-times . /home/backup-user/test
在发送给客户端的rsync命令中添加一些详细信息,它说(注意远程协议版本):
FILE_STRUCT_LEN=24,EXTRA_LEN=4 (Server) Protocol versions: remote=168430090,negotiated=31 protocol version mismatch -- is your shell clean? (see the rsync man page for an explanation) [sender] _exit_cleanup(code=2,file=compat.c,line=178): entered rsync error: protocol incompatibility (code 2) at compat.c(178) [sender=3.1.2] [sender] _exit_cleanup(code=2,line=178): about to call exit(2)
看起来远程协议中的168430090是十进制的
代表0xA0A0A0A,但不知道是什么写的.我在列表中搜索了类似的错误,但我找到的所有错误都归功于我已经检查过的内容.
在客户端中,使用我在rsync站点中找到的调试脚本:
/usr/bin/ssh -q -x -l backup-user 192.168.206.103 /home/backup-user/rsync-debug --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --ignore-times . /home/backup-user/test

这是脚本停止的地方.我必须在服务器中多次返回.然后它继续:

经过几个小时的研究,我无法弄清楚出了什么问题.我删除了
并检查了所有可以写任何文本的内容(ssh welcome message,
.bashrc echos,passphrase甚至系统提示)和rsync仍然是
无法收集文件. ssh连接是无密码的.
我也做了真正的> testfile测试,没有问题:
backup-user@backup:~$/usr/bin/ssh -q -x -l backup-user 192.168.10.20 true > testfile backup-user@backup:~$ll testfile -rw-r--r-- 1 backup-user backup-user 0 feb 16 02:26 testfile
线条:
2997 00:58:30 open("/etc/popt",O_RDONLY) = -1 ENOENT (No such file or directory)
看起来很可疑,但也检查了涉及的库.
选项–server和–sender由BackupPC添加,但不应该
正如rsync文档所述,需要在常规使用中使用.
有人发现了同样的问题吗?我知道通常这是由在终端上写入数据的东西引起的,但是使用调试脚本我可以看到rsync是写入数据的过程.
希望这些信息足够清晰.谢谢你的时间.
