SSHFS(1)

NAME
SSHFS - filesystem client based on ssh

SYNOPSIS

  mounting

sshfs [user@]host:[dir] mountpoint [options]

  unmounting

umount mountpoint

DESCRIPTION
SSHFS (Secure SHell FileSystem) is a file system for Linux (and other operating systems with a FUSE implementation, such as Mac OS X or FreeBSD) capable of operating on files on a remote computer using just a secure shell login on the remote computer. On the local computer where the SSHFS is mounted, the implementation makes use of the FUSE (Filesystem in Userspace) kernel module. The practical effect of this is that the end user can seamlessly interact with remote files being securely served over SSH just as if they were local files on his/her computer. On the remote computer the SFTP subsystem of SSH is used.

If host is a numeric IPv6 address, it needs to be enclosed in square brackets.

    print version

  SSHFS options:

-p PORT
    equivalent to '-o port=PORT'

-C  equivalent to '-o compression=yes'

-F ssh_configfile
    specifies alternative ssh configuration file

-1  equivalent to '-o ssh_protocol=1'

-o reconnect
    reconnect to server

-o delay_connect
    delay connection to server

-o sshfs_sync
    synchronous writes

-o no_readahead
    synchronous reads (no speculative readahead)

-o sync_readdir
    synchronous readdir

-o sshfs_debug
    print some debugging information

-o cache=BOOL
    enable caching {yes,no} (default: yes)

-o cache_timeout=N
    sets timeout for caches in seconds (default: 20)

-o cache_X_timeout=N
    sets timeout for {stat,dir,link} cache

-o workaround=LIST
    colon separated list of workarounds

    none
        no workarounds enabled

    all all workarounds enabled

    [no]rename
        fix renaming to existing file (default: off)

    [no]nodelaysrv
        set nodelay tcp flag in ssh (default: off)

    [no]truncate
        fix truncate for old servers (default: off)

    [no]buflimit
        fix buffer fillup bug in server (default: on)

-o idmap=TYPE
    user/group ID mapping (default: none)

    none
        no translation of the ID space

    user
        only translate UID/GID of connecting user

    file
        translate UIDs/GIDs based upon the contents of uidfile and gidfile

-o uidfile=FILE
    file containing username:uid mappings for idmap=file

-o gidfile=FILE
    file containing groupname:gid mappings for idmap=file

-o nomap=TYPE
    with idmap=file, how to handle missing mappings

    ignore
        don't do any re-mapping

    error
        return an error (default)

-o ssh_command=CMD
    execute CMD instead of 'ssh'

-o ssh_protocol=N
    ssh protocol to use (default: 2)

-o sftp_server=SERV
    path to sftp server or subsystem (default: sftp)

-o directport=PORT
    directly connect to PORT bypassing ssh -o slave communicate over stdin and stdout bypassing network

-o slave
    communicate over stdin and stdout bypassing network

-o disable_hardlink
    link(2) will return with errno set to ENOSYS. Hard links don't currently work perfectly on sshfs, and this confuses some programs. If that happens try disabling hard links with this option.

-o transform_symlinks
    transform absolute symlinks to relative

-o follow_symlinks
    follow symlinks on the server

-o no_check_root
    don't check for existence of 'dir' on server

-o password_stdin
    read password from stdin (only for pam_mount!)

-o SSHOPT=VAL
    ssh options (see man ssh_config)

  FUSE options:

-d   -o debug
    enable debug output (implies -f)

-f  foreground operation

-s  disable multi-threaded operation

-o allow_other
    allow access to other users

-o allow_root
    allow access to root

-o nonempty
    allow mounts over non-empty file/dir

-o default_permissions enable permission checking by kernel

-o fsname=NAME
    set filesystem name

-o subtype=NAME
    set filesystem type

-o large_read
    issue large read requests (2.4 only)

-o max_read=N
    set maximum size of read requests

-o hard_remove
    immediate removal (don't hide files)

-o kernel_cache
    cache files in kernel

-o [no]auto_cache
    enable caching based on modification times

-o umask=M
    set file permissions (octal)

-o uid=N
    set file owner

-o gid=N
    set file group

-o entry_timeout=T
    cache timeout for names (1.0s)

-o negative_timeout=T
    cache timeout for deleted names (0.0s)

-o attr_timeout=T
    cache timeout for attributes (1.0s)

-o ac_attr_timeout=T
    auto cache timeout for attributes (attr_timeout)

-o intr
    allow requests to be interrupted

-o intr_signal=NUM
    signal to send on interrupt (10)

-o modules=M1[:M2...]
