# plpnfsd(8)

Daemon to mount a Psion like an NFS file-system

## 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 /var/lib/plptools/mnt). 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 */var/lib/plptools/mnt*

- **-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 /var/lib/plptools/mnt/proc there are several special files which can be used to control plpnfsd and/or view some information of the connected Psion.

- /var/lib/plptools/mnt/proc/exit

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

- /var/lib/plptools/mnt/proc/owner

  shows the Psion's owner information.

- /var/lib/plptools/mnt/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.

- /var/lib/plptools/mnt/proc/debuglevel

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

- /var/lib/plptools/mnt/proc/acache

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

- /var/lib/plptools/mnt/proc/dcache

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

- /var/lib/plptools/mnt/proc/\<number\>/cmd

  Shows the name of the corresponding process on the Psion.

- /var/lib/plptools/mnt/proc/\<number\>/args

  Shows the arguments of the corresponding process on the Psion.
