| 1 | V9FS: 9P2000 for Linux | ||
| 2 | ====================== | ||
| 3 | |||
| 4 | ABOUT | ||
| 5 | ===== | ||
| 6 | |||
| 7 | v9fs is a Unix implementation of the Plan 9 9p remote filesystem protocol. | ||
| 8 | |||
| 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> and Latchesar Ionkov <lucho@ionkov.net>. | ||
| 13 | |||
| 14 | USAGE | ||
| 15 | ===== | ||
| 16 | |||
| 17 | For remote file server: | ||
| 18 | |||
| 19 | mount -t 9P 10.10.1.2 /mnt/9 | ||
| 20 | |||
| 21 | For 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 | |||
| 25 | OPTIONS | ||
| 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. | ||
| 73 | |||
| 74 | RESOURCES | ||
| 75 | ========= | ||
| 76 | |||
| 77 | The Linux version of the 9P server, along with some client-side utilities | ||
| 78 | can be found at http://v9fs.sf.net (along with a CVS repository of the | ||
| 79 | development branch of this module). There are user and developer mailing | ||
| 80 | lists here, as well as a bug-tracker. | ||
