SSHFS - filesystem client based on ssh



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




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.


general options:

-o opt,[opt...]
mount options
-h --help
print help
-V --version
print version

SSHFS options:

equivalent to '-o port=PORT'
equivalent to '-o compression=yes'
-F ssh_configfile
specifies alternative ssh configuration file
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
no workarounds enabled
all workarounds enabled
fix renaming to existing file (default: off)
set nodelay tcp flag in ssh (default: off)
fix truncate for old servers (default: off)
fix buffer fillup bug in server (default: on)
-o idmap=TYPE
user/group ID mapping (default: "none")
no translation of the ID space
only translate UID/GID of connecting user
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
don't do any re-mapping
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 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!)
ssh options (see man ssh_config)

foreground operation
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 use_ino
let filesystem set inode numbers
-o readdir_ino

-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...]
names of modules to push onto filesystem stack
-o max_write=N
set maximum size of write requests
-o max_readahead=N
