DESCRIPTION

plpnfsd is a daemon, which provides NFS-like access to
your Psion. It automatically makes the Psion's file-sys
tems available below an NFS-mounted directory (default
/mnt/psion). By default, plpnfsd is installed suid-root,
so any normal user can start it and gets the mounted
directory owned by himself. As this program is usually
used on single-user machines, this does not hurt security.
Like the other front-ends, this program auto-reconnects
after a link-failure, so you can keep the psion mounted
all the time, even when it is not connected. Due to
Rudolf Koenig's clever error-handling, you don't need to
worry about blocked io-processes if the psion isn't avail
able. You simply will get an "device not configured"
error, when accessing a file on a previously connected
psion which has been disconnected. After that, the mountpoint will appear with the drives missing. As soon as the
psion is connected again, the subdirectories will reappear
(possibly with a few seconds delay).

OPTIONS

-V, --version

Display the version and exit

-h, --help

Display a short help text and exit.

-v, --verbose

Produce verbose logging output. Can be specified
more than once to increase the debug level (up to 3
times)

-p, --port=[host:]port

Specify the host and port to connect to (e.g. the
port where ncpd is listening on) - by default the
host is 127.0.0.1 and the port is looked up in
/etc/services. If it is not found there, a fallback builtin of 7501.

-d, --mountpoint=mount-dir

Specify the directory to mount the psion file sys
tem on. This defaults to /mnt/psion

-u, --user=user

Specify the user who will own the psion files. This
defaults to the user who is running plpnfsd. If the
user running plpnfsd is root , s/he may also spec
ify a different user.

FILES

Below the special directory /mnt/psion/proc there are
several special files which can be used to control plpnfsd
and/or view some information of the connected Psion.

/mnt/psion/proc/exit

can be used to shutdown plpnfsd gracefully. To
shutdown plpnfsd write the string "stop" into that
file.

/mnt/psion/proc/owner

shows the Psion's owner information.

/mnt/psion/proc/unixowner

The superuser (root) can set the owner of the
mounted directory-tree during runtime by writing
the desired user-name into this file.

/mnt/psion/proc/debuglevel

Reading/writing from/to this file shows resp. sets
the debug level.

/mnt/psion/proc/acache

Reading/writing from/to this file shows resp. sets
the timeout value for the attribute cache in sec
onds.

/mnt/psion/proc/dcache

Reading/writing from/to this file shows resp. sets
the timeout value for the data cache in seconds.

/mnt/psion/proc/<number>/cmd

Shows the name of the corresponding process on the
Psion.

/mnt/psion/proc/<number>/args

Shows the arguments of the corresponding process on
the Psion.
