- 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
- =========
- The Linux version of the 9p server is now maintained under the npfs project
- on sourceforge (http://sourceforge.net/projects/npfs).
- There are user and developer mailing lists available through the v9fs project
- on sourceforge (http://sourceforge.net/projects/v9fs).
- News and other information is maintained on SWiK (http://swik.net/v9fs).
- Bug reports may be issued through the kernel.org bugzilla
- (http://bugzilla.kernel.org)

- For information on Plan 9 from User Space (Plan 9 applications and libraries
- ported to Linux/BSD/OSX/etc) check out http://swtch.com/plan9
- STATUS
- ======
- The 2.6 kernel support is working on PPC and x86.
- PLEASE USE THE SOURCEFORGE BUG-TRACKER TO REPORT PROBLEMS.
