EXPORTFS(4)                Kernel Interfaces Manual                EXPORTFS(4)



NAME
       exportfs, srvfs - network file server plumbing

SYNOPSIS
       exportfs [ -an ] [ -c ctlfile ]

       srvfs name dir

DESCRIPTION
       Exportfs  is  a  user  level  file  server  that  allows Plan 9 compute
       servers, rather than file servers, to export portions of a  name  space
       across  networks.   The service is started either by the cpu(1) command
       or by a network listener process.  An initial  protocol  establishes  a
       root directory for the exported name space.  The connection to exportfs
       is then mounted, typically on /mnt/term.  Exportfs then acts as a relay
       file  server:  operations in the imported file tree are executed on the
       remote server and the results returned.  This gives the  appearance  of
       exporting a name space from a remote machine into a local file tree.

       The  -a  option  instructs  exportfs  to authenticate the user, usually
       because it is being invoked from a remote machine.

       The -n option disallows export to user none.

       The -c options specifies a network control  file  onto  which  exportfs
       will  push the fcall line discipline.  This option is intended for net-
       works that do not preserve read/write boundaries.

       The cpu command uses exportfs to serve device files  in  the  terminal.
       The  import(4)  command  calls exportfs on a remote machine, permitting
       users to access arbitrary pieces of name space on other systems.

       Srvfs uses exportfs to create a  mountable  file  system  from  a  name
       space: a subsequent mount (see bind(1)) of /srv/name will reproduce the
       name space rooted at dir.  One might use srvfs to enable mounting of an
       FTP file system (see ftpfs(4)) in several windows.
