v9fs: Plan 9 Resource Sharing 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>, Latchesar Ionkov <lucho@ionkov.net> and Russ Cox
|
|
<rsc@swtch.com>.
|
|
|
|
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,uname=$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)
|
|
|
|
uname=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
|
|
|
|
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.
|
|
