V9FS: 9P2000 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> and Latchesar Ionkov <lucho@ionkov.net>. 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,name=$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) name=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 timeout=n request timeouts (in ms) (default 60000ms) 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, along with some client-side utilities can be found at http://v9fs.sf.net (along with a CVS repository of the development branch of this module). There are user and developer mailing lists here, as well as a bug-tracker.
