ftpfs - file transfer protocol (FTP) file system
ftpfs [ -/dq ] [ -m mountpoint ] [ -a password ] system
Ftpfs dials the TCP file transfer protocol (FTP) port, 21, on system and mounts itself
(see bind(2)) on mountpoint (default /n/ftp) to provide access to files on the remote
machine. If required by the remote machine, ftpfs will prompt for a user name and pass-
word. The user names ftp and anonymous conventionally offer guest/read-only access to
machines. Anonymous FTP may be called without user interaction by using the -a option and
specifying the password.
By default the file seen at the mount point is the user's remote home directory. The
option -/ forces the mount point to correspond to the remote root.
To avoid seeing startup messages from the server use option -q. To see all messages from
the server use option -d.
To terminate the connection, unmount (see bind(1)) the mount point.
You want anonymous FTP access to the system export.lcs.mit.edu. The first import(4) com-
mand is only necessary if your machine does not have access to the desired system, but
another, called gateway in this example, does.
import gateway /net
ftpfs -a yourname@yourmachine export.lcs.mit.edu
Symbolic links on remote Unix systems will always have mode 0777 and a length of 8.
After connecting to a TOPS-20 system, the mount point will contain only one directory,
usually /n/ftp/PS:<ANONYMOUS>. However, walking to any valid directory on that machine
will succeed and cause that directory entry to appear under the mount point.
Ftpfs caches files and directories. A directory will fall from the cache after 5 quies-
cent minutes or if the local user changes the directory by writing or removing a file.
Otherwise, remote changes to the directory that occur after the directory has been cached
might not be immediately visible.
There is no way to issue the appropriate commands to handle special synthetic FTP file
types such as directories that automatically return a tar of their contents.
