NAME

plpnfsd - Daemon to mount a Psion an nfs like filesystem

SYNOPSIS

plpnfsd [-V [-v [-p__ ''port''__ [unrenderable node] [-u__ ''user''__

DESCRIPTION

plpnfsd is a daemon, which provides NFS-like access to your Psion. It automatically makes the psion's filesystems available below an NFS-mounted directory (default /mnt/psion). By default, plpnfsd is installed suid-root, so any normal user can start it and get's the mounted directory owned by himself. As this program is usually used on single-user machines, this does not hurt security. Like the others, 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

OPTIONS

-V

Display the version and exit

-v

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

-p port

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

-d mountdir

Specify the directory to mount the psion file system on. This defaults to /var/lib/plptools/mnt

-u 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

/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 username 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/

Shows the name of the corresponding process on the Psion.

/var/lib/plptools/mnt/proc/

Shows the arguments of the corresponding process on the Psion.
