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.
