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 appear-
       ance 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.
