1 v9fs: Plan 9 Resource Sharing for Linux
2 =======================================
5 =====
7 v9fs is a Unix implementation of the Plan 9 9p remote filesystem protocol.
9 This software was originally developed by Ron Minnich <rminnich@lanl.gov>
10 and Maya Gokhale <maya@lanl.gov>. Additional development by Greg Watson
11 <gwatson@lanl.gov> and most recently Eric Van Hensbergen
12 <ericvh@gmail.com>, Latchesar Ionkov <lucho@ionkov.net> and Russ Cox
13 <rsc@swtch.com>.
16 =====
18 For remote file server:
20 mount -t 9p /mnt/9
22 For Plan 9 From User Space applications (http://swtch.com/plan9)
24 mount -t 9p `namespace`/acme /mnt/9 -o proto=unix,uname=$USER
27 =======
29 proto=name select an alternative transport. Valid options are
30 currently:
31 unix - specifying a named pipe mount point
32 tcp - specifying a normal TCP/IP connection
33 fd - used passed file descriptors for connection
34 (see rfdno and wfdno)
36 uname=name user name to attempt mount as on the remote server. The
37 server may override or ignore this value. Certain user
38 names may require authentication.
40 aname=name aname specifies the file tree to access when the server is
41 offering several exported file systems.
43 debug=n specifies debug level. The debug level is a bitmask.
44 0x01 = display verbose error messages
45 0x02 = developer debug (DEBUG_CURRENT)
46 0x04 = display 9p trace
47 0x08 = display VFS trace
48 0x10 = display Marshalling debug
49 0x20 = display RPC debug
50 0x40 = display transport debug
51 0x80 = display allocation debug
53 rfdno=n the file descriptor for reading with proto=fd
55 wfdno=n the file descriptor for writing with proto=fd
57 maxdata=n the number of bytes to use for 9p packet payload (msize)
59 port=n port to connect to on the remote server
61 noextend force legacy mode (no 9p2000.u semantics)
63 uid attempt to mount as a particular uid
65 gid attempt to mount with a particular gid
67 afid security channel - used by Plan 9 authentication protocols
69 nodevmap do not map special files - represent them as normal files.
70 This can be used to share devices/named pipes/sockets between
71 hosts. This functionality will be expanded in later versions.
74 =========
76 The Linux version of the 9p server is now maintained under the npfs project
77 on sourceforge (http://sourceforge.net/projects/npfs).
79 There are user and developer mailing lists available through the v9fs project
80 on sourceforge (http://sourceforge.net/projects/v9fs).
82 News and other information is maintained on SWiK (http://swik.net/v9fs).
84 Bug reports may be issued through the kernel.org bugzilla
85 (http://bugzilla.kernel.org)
