FTPFS(4)                   Kernel Interfaces Manual                   FTPFS(4)



NAME
       ftpfs  - file transfer protocol (FTP) file system

SYNOPSIS
       ftpfs [ -/dq ] [ -m mountpoint ] [ -a password ] system

DESCRIPTION
       Ftpfs  dials  the  TCP file transfer protocol (FTP) port, 21, on system
       and mounts itself (see bind(2)) on mountpoint (default /n/ftp) to  pro-
       vide  access to files on the remote machine.  If required by the remote
       machine, ftpfs will prompt for a user  name  and  password.   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.

EXAMPLE
       You want anonymous FTP access to the  system  export.lcs.mit.edu.   The
       first import(4) command is only necessary if your machine does not have
       access to the desired system, but another, called gateway in this exam-
       ple, does.

              import gateway /net
              ftpfs -a yourname@yourmachine export.lcs.mit.edu

SOURCE
       /sys/src/cmd/ftpfs

BUGS
       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:<&lt;ANONYMOUS>&gt;.  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 quiescent minutes or if the local user changes the direc-
       tory  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.
