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 | ||
| 93fa58cb EVH |
60 | noextend force legacy mode (no 9P2000.u semantics) |
| 61 | ||
| 62 | uid attempt to mount as a particular uid | |
| 63 | ||
| 64 | gid attempt to mount with a particular gid | |
| 65 | ||
| 66 | afid security channel - used by Plan 9 authentication protocols | |
| 67 | ||
| 68 | nodevmap do not map special files - represent them as normal files. | |
| 69 | This can be used to share devices/named pipes/sockets between | |
| 70 | hosts. This functionality will be expanded in later versions. | |
