1 V9FS: 9P2000 for Linux
2 ======================
3
4ABOUT
5=====
6
7v9fs is a Unix implementation of the Plan 9 9p remote filesystem protocol.
8
9This software was originally developed by Ron Minnich <rminnich@lanl.gov>
10and Maya Gokhale <maya@lanl.gov>. Additional development by Greg Watson
11<gwatson@lanl.gov> and most recently Eric Van Hensbergen
12<ericvh@gmail.com> and Latchesar Ionkov <lucho@ionkov.net>.
13
14USAGE
15=====
16
17For remote file server:
18
19 mount -t 9P 10.10.1.2 /mnt/9
20
21For Plan 9 From User Space applications (http://swtch.com/plan9)
22
23 mount -t 9P `namespace`/acme /mnt/9 -o proto=unix,name=$USER
24
25OPTIONS
26=======
27
28 proto=name select an alternative transport. Valid options are
29 currently:
30 unix - specifying a named pipe mount point
31 tcp - specifying a normal TCP/IP connection
32 fd - used passed file descriptors for connection
33 (see rfdno and wfdno)
34
35 name=name user name to attempt mount as on the remote server. The
36 server may override or ignore this value. Certain user
37 names may require authentication.
38
39 aname=name aname specifies the file tree to access when the server is
40 offering several exported file systems.
41
42 debug=n specifies debug level. The debug level is a bitmask.
43 0x01 = display verbose error messages
44 0x02 = developer debug (DEBUG_CURRENT)
45 0x04 = display 9P trace
46 0x08 = display VFS trace
47 0x10 = display Marshalling debug
48 0x20 = display RPC debug
49 0x40 = display transport debug
50 0x80 = display allocation debug
51
52 rfdno=n the file descriptor for reading with proto=fd
53
54 wfdno=n the file descriptor for writing with proto=fd
55
56 maxdata=n the number of bytes to use for 9P packet payload (msize)
57
58 port=n port to connect to on the remote server
59
60 timeout=n request timeouts (in ms) (default 60000ms)
61
62 noextend force legacy mode (no 9P2000.u semantics)
63
64 uid attempt to mount as a particular uid
65
66 gid attempt to mount with a particular gid
67
68 afid security channel - used by Plan 9 authentication protocols
69
70 nodevmap do not map special files - represent them as normal files.
71 This can be used to share devices/named pipes/sockets between
72 hosts. This functionality will be expanded in later versions.

74RESOURCES
75=========
76
77The Linux version of the 9P server, along with some client-side utilities
78can be found at http://v9fs.sf.net (along with a CVS repository of the
79development branch of this module). There are user and developer mailing
80lists here, as well as a bug-tracker.
