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 more information on the Plan 9 Operating System check out http://plan9.bell-labs.com/plan9 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.
