NAME

plpnfsd - Daemon to mount a Psion like an NFS file-system

SYNOPSIS

plpnfsd [-V] [-v] [-D] [-h] [-p [host:]port] [-d mount-dir] [-u user] [long-options]

DESCRIPTION

plpnfsd is a daemon, which provides NFS-like access to your Psion. It automatically makes the Psion's file-systems 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 available. 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 mount-point 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 fall-back builtin of 7501.
-d, --mountpoint=mount-dir
Specify the directory to mount the psion file system 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 specify 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 seconds.
/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.
