带有sshfs的autofs不再起作用[关闭]


8

我刚刚从Ubuntu 12.04升级到12.10。在此之前,我备份了可以正常工作的autofs配置。我将旧的行添加/etc/auto.master到新的行:

+dir:/etc/auto.master.d
+auto.master
/mnt /etc/auto.sshfs uid=1000,gid=1000,--timeout=30,--ghost,--verbose

我的/etc/auto.sshfs样子是这样的:

mymount -fstype=fuse,rw,nodev,nonempty,noatime,allow_other,max_read=65536 :sshfs\#myuser@mydomain:/mnt/mymount

我得到了手动尝试,Connetion reset by peer所以我添加了option IdentityFile=/home/myuser/.ssh/id_rsa。现在,当我尝试访问时/mnt(使用手动和autofs),就会发生这种情况:

myuser@laptop /mnt % la
ls: cannot access mymount: No such file or directory
total 4
drwxr-xr-x  3 root root    0 Oct 19 10:34 ./
drwxr-xr-x 25 root root 4096 Oct 18 23:17 ../
d?????????  ? ?    ?       ?            ? mymount/

我已经检查了UID和GID,它们与我的用户匹配。我的用户的SSH密钥到位。我也尝试/mnt/mymount手动创建,但是奇怪的是,只要autofs正在运行,它甚至会以root身份返回“权限被拒绝”(猜测应该是这种方式)。

任何想法可能有什么问题吗?我必须通过配置步骤忘记之前做过的事情。


根据您的问题,我认为它也无法手动运行。最好先尝试调试此问题,例如通过启用调试输出(请参阅参考资料sshfs(1))-这里涉及很多事情(保险丝,ssh,autofs)……普通ssh(或sftp)连接是否正常工作?
sr_

Plain ssh正常工作。我必须承认我没有尝试手动安装sshfs。有时候,您没有想到最琐碎的事情。我尝试了一个实际得到Connection reset by peer。之后,我将ssh密钥手动添加到选项中。现在我有另一个错误。为此将更新我的问题。
安德烈Stannek

@André只是为了澄清,您是说在同时使用autofs和手动安装时,会遇到cannot access mymount错误?????吗?
帕特里克

老实说,半年后我不确定自己当时尝试过什么;-)我想我尝试手动安装以查看问题是否出在我的保险丝选件或autofs中。稍后我可以尝试重新构建问题,但是今天我的时间很短。

有一些陷阱可能会导致您遇到问题。截至本回答之时,您已经解决了其中一个问题,但我将全部解决(您的当前问题是由#3引起的)。

1-身份文件

这是您解决的问题。当运行sshfs从autofs挂载,sshfs运行作为root用户,所以它使用默认的根的SSH密钥。您必须指定IdentityFile=/home/user/.ssh/id_rsa使用其他密钥。

2-已知主机

另外,由于您以sshfs与通常不同的用户身份运行,因此必须确保要安装的远程主机位于known_hosts文件中。有几种解决此问题的方法。

  1. 以root身份一次登录到远程主机,并接受远程主机的密钥。
  2. 添加参数StrictHostKeyChecking=no。这将使ssh接受它看到的任何密钥(因此引入了一些不安全性)。
  3. 添加参数UserKnownHostsFile=/home/user/.ssh/known_hosts。这将使它使用known_hosts普通用户的文件。

3-保险丝allow_other

默认情况下,保险丝文件系统(sshfs是)不允许安装文件系统的用户以外的其他用户访问它。由于autofs以root身份运行,因此默认情况下,只有root可以访问它。其他任何人都没有权限(即使由非root用户安装,也没有权限),即使实际文件权限表明他们应该也可以。为了解决这个问题,您必须添加mount选项allow_other。这将允许安装它的用户以外的其他用户访问该安装。尽管访问仍将遵循挂载上文件的文件级权限。


对我没有帮助。如您所见,我已经解决了第一个问题。正如您在我的问题中看到allow_other/etc/auto.sshfs那样,第二个选项与该选项相同。我也经常使用ssh,因此也存在已知的主机条目。
安德烈Stannek

@AndréStannek哇,旧评论,但是known_hosts您检查了哪一个?从您关于经常使用ssh的评论来看,我猜您已经检查了用户的known_hosts。您需要检查root,因为调用ssh的是root。
Patrick

抱歉,但是现在我不再使用像这样的autofs了。Ubuntu的安装我以前甚至不存在了;-)

您是否尝试过使用调试选项运行autofs?

sudo automount --debug -f /etc/auto.master 将为您提供调试输出到运行终端。

您是否已将root和用户添加到保险丝组?

sudo gpasswd -a $USER fuse


调试行非常有帮助。对我来说,/etc/auto.sshfs文件中指定了一个未知选项。
