| 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. |
| |
| RESOURCES |
| ========= |
