我知道这个问题已经讨论过很多次了，我几乎觉得惭愧，我还没有find解决scheme。 显然有一些我不明白，真的很感激任何input或指针。

研究背景

• Linux 3.2.0-4-amd64＃1 SMP Debian 3.2.51-1 x86_64 GNU / Linux
• 所有cmd都以root用户身份运行，并且ssh密钥已被复制到远程的.ssh / authorized_keys中
• 使用ssh-agent来解锁密钥
• 正常的sshfs cmd按预期工作 – sshfs USER@REMOTE:/ /mnt/ssh/backup
• 将条目添加到fstab并执行“mount -a”按预期工作 – sshfs#USER@REMOTE:/ /mnt/ssh/backup/ fuse defaults 0 0

＃：automount -V

 Linux automount version 5.0.7 Directories: config dir: /etc/default maps dir: /etc modules dir: /usr/lib/x86_64-linux-gnu/autofs Compile options: ENABLE_FORCED_SHUTDOWN ENABLE_IGNORE_BUSY_MOUNTS WITH_HESIOD WITH_LDAP WITH_SASL LIBXML2_WORKAROUND 

＃：automount -m

 autofs dump map information =========================== global options: none configured Mount point: /mnt/ssh source(s): instance type(s): file map: /etc/auto.sshfs backup | -fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536 :sshfs#USER@REMOTE:/ 

auto.master文件

• 使用sec = krb5 *的NFS导出是否需要使用sec = krb5导出父目录？
• 如何防止autofs挂载在特定的目录？
• 什么是autofs安装凭据文件的正确转义？
• 保持用户的文件系统在AWS EC2现货实例中保持一致
• 为什么在Docker容器中的一些主机卷会给出错误“符号链接的级别太多”？

 /mnt/ssh /etc/auto.sshfs --timeout=30,--ghost,--debug 

auto.sshfs

 backup -fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536 :sshfs#USER@REMOTE:/ 

当我在前台自动挂载auto.master（详情如下）时，将创build“backup”文件夹，并且远程目录根本不会被挂载。 我可以ls -al / mnt / ssh / backup文件夹，确实正在浏览远程主机

 #:automount -f -v -d auto.master #:ls -al /mnt/ssh/backup attempting to mount entry /mnt/ssh/backup lookup_mount: lookup(file): looking up backup lookup_mount: lookup(file): backup -> -fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536 :sshfs#USER@REMOTE:/ parse_mount: parse(sun): expanded entry: -fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536 :sshfs#USER@REMOTE:/ parse_mount: parse(sun): gathered options: fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536 parse_mount: parse(sun): dequote(":sshfs#USER@REMOTE:/") -> :sshfs#USER@REMOTE:/ parse_mount: parse(sun): core of entry: options=fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536, loc=:sshfs#USER@REMOTE:/ sun_mount: parse(sun): mounting root /mnt/ssh, mountpoint backup, what sshfs#USER@REMOTE:/, fstype fuse, options rw,nodev,noatime,allow_other,default_permissions,max_read=65536 do_mount: sshfs#USER@REMOTE:/ /mnt/ssh/backup type fuse options rw,nodev,noatime,allow_other,default_permissions,max_read=65536 using module generic mount_mount: mount(generic): calling mkdir_path /mnt/ssh/backup mount_mount: mount(generic): calling mount -t fuse -s -o rw,nodev,noatime,allow_other,default_permissions,max_read=65536 sshfs#USER@REMOTE:/ /mnt/ssh/backup spawn_mount: mtab link detected, passing -n to mount mount_mount: mount(generic): mounted sshfs#USER@REMOTE:/ type fuse on /mnt/ssh/backup 

但是，当我启动autofs服务如下所述，“备份”文件夹被创build，但只要我试图ls目录，它只是拒绝安装。

 #:service autofs start #:ls -al /mnt/ssh/backup attempting to mount entry /mnt/ssh/backup lookup_mount: lookup(file): looking up backup lookup_mount: lookup(file): backup -> -fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536 :sshfs#USER@REMOTE:/ parse_mount: parse(sun): expanded entry: -fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536 :sshfs#USER@REMOTE:/ parse_mount: parse(sun): gathered options: fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536 parse_mount: parse(sun): dequote(":sshfs#USER@REMOTE:/") -> :sshfs#USER@REMOTE:/ parse_mount: parse(sun): core of entry: options=fstype=fuse,rw,nodev,noatime,allow_other,default_permissions,max_read=65536, loc=:sshfs#USER@REMOTE:/ sun_mount: parse(sun): mounting root /mnt/ssh, mountpoint backup, what sshfs#USER@REMOTE:/, fstype fuse, options rw,nodev,noatime,allow_other,default_permissions,max_read=65536 do_mount: sshfs#USER@REMOTE:/ /mnt/ssh/backup type fuse options rw,nodev,noatime,allow_other,default_permissions,max_read=65536 using module generic mount_mount: mount(generic): calling mkdir_path /mnt/ssh/backup mount_mount: mount(generic): calling mount -t fuse -s -o rw,nodev,noatime,allow_other,default_permissions,max_read=65536 sshfs#USER@REMOTE:/ /mnt/ssh/backup spawn_mount: mtab link detected, passing -n to mount >> read: Connection reset by peer mount(generic): failed to mount sshfs#USER@REMOTE:/ (type fuse) on /mnt/ssh/backup dev_ioctl_send_fail: token = 22 failed to mount /mnt/ssh/backup 

我已经testing了许多解决方法，包括但不限于

• 转义：sshfs＃USER @ REMOTE：/ – :sshfs\#USER@REMOTE\:/
• 删除/ – :sshfs#USER@REMOTE:
• 在auto.sshfs中提供我的身份文件的path – IdentityFile=/root/.ssh/id_rsa
• 在auto.master中指定uid / gid – /mnt/ssh /etc/auto.sshfs uid=0,gid=0,--timeout=30,--ghost

我现在没有想法，卡住了。

在此先感谢，JS

UPDATE

@KaszpiR – 感谢您的努力，但正确的密钥已经上传到远程的authorized_keys文件和标准的sftp或sshfs完美地工作。

看来，autofs initscript（或用于在脚本中启动automount的选项之一）正在创build问题，但没有足够的时间来正确debugging它。

作为解决方法，您可以完全删除/etc/init.d/autofs脚本（update-rc.d autofs删除并将其移至备份位置以便妥善保pipe），然后手动或通过脚本启动automount。

 sudo su - ssh-keygen -t rsa ssh-copy-id -i ~/.ssh/id_rsa.pub remote_user@remote_server
