V9FS: 9P2000 for Linux
======================
ABOUT
=====
v9fs is a Unix implementation of the Plan 9 9p remote filesystem protocol.
This software was originally developed by Ron Minnich <rminnich@lanl.gov>
and Maya Gokhale <maya@lanl.gov>. Additional development by Greg Watson
<gwatson@lanl.gov> and most recently Eric Van Hensbergen
<ericvh@gmail.com> and Latchesar Ionkov <lucho@ionkov.net>.
USAGE
=====
For remote file server:
mount -t 9P 10.10.1.2 /mnt/9
For Plan 9 From User Space applications (http://swtch.com/plan9)
mount -t 9P `namespace`/acme /mnt/9 -o proto=unix,name=$USER
OPTIONS
=======
proto=name select an alternative transport. Valid options are
currently:
unix - specifying a named pipe mount point
tcp - specifying a normal TCP/IP connection
fd - used passed file descriptors for connection
(see rfdno and wfdno)
name=name user name to attempt mount as on the remote server. The
server may override or ignore this value. Certain user
names may require authentication.
aname=name aname specifies the file tree to access when the server is
offering several exported file systems.
debug=n specifies debug level. The debug level is a bitmask.
0x01 = display verbose error messages
0x02 = developer debug (DEBUG_CURRENT)
0x04 = display 9P trace
0x08 = display VFS trace
0x10 = display Marshalling debug
0x20 = display RPC debug
0x40 = display transport debug
0x80 = display allocation debug
rfdno=n the file descriptor for reading with proto=fd
wfdno=n the file descriptor for writing with proto=fd
maxdata=n the number of bytes to use for 9P packet payload (msize)
port=n port to connect to on the remote server
timeout=n request timeouts (in ms) (default 60000ms)
noextend force legacy mode (no 9P2000.u semantics)
uid attempt to mount as a particular uid
gid attempt to mount with a particular gid
afid security channel - used by Plan 9 authentication protocols
nodevmap do not map special files - represent them as normal files.
This can be used to share devices/named pipes/sockets between
hosts. This functionality will be expanded in later versions.
RESOURCES
=========
The Linux version of the 9P server, along with some client-side utilities
can be found at http://v9fs.sf.net (along with a CVS repository of the
development branch of this module). There are user and developer mailing
lists here, as well as a bug-tracker.
For more information on the Plan 9 Operating System check out
http://plan9.bell-labs.com/plan9
For information on Plan 9 from User Space (Plan 9 applications and libraries
ported to Linux/BSD/OSX/etc) check out http://swtch.com/plan9
STATUS
======
The 2.6 kernel support is working on PPC and x86.
PLEASE USE THE SOURCEFORGE BUG-TRACKER TO REPORT PROBLEMS.
