NAME

       jazip - X tool to easily mount and unmount Iomega Zip and/or Jaz drives.

SYNOPSIS

       jazip [SCSI device] [-display host:dpy] [-visual visual] [-depth depth] [-private]

DESCRIPTION

       jazip  is  a  program  for  maintaing  your Iomega Zip and/or Jaz drive(s) and disks under
       Linux. This program combines Grant Guenther's original command line utility, ziptool, with
       Jaz  drive  support,  a nice X interface and additional utilities to allow users to easily
       mount and unmount disks.  The interface is based on version 0.88 of the XForms library.

OPTIONS

       The optional SCSI device command line parameter specifies the raw scsi device name of  one
       of  the  drives  with  an entry in /etc/jazip.conf.  If no SCSI device is specified on the
       command line, jazip will use the first entry of /etc/jazip.conf by default.   This  allows
       you  to  add  a  different line in the configuration file for each drive you own, and then
       invoke jazip with the name of the device for the drive you want jazip to use.

       Note that the SCSI device argument does not  contain  a  partition  number.   jazip  auto-
       detects partitions and mounts the first one it encounters.

       jazip  is built with the XForms Graphical User Interface Toolkit for X, and hence supports
       a number of flags which are interpreted by XForms:

       -display host:dpy
              defines the X display.

       -visual class
              TrueColor, PseudoColor etc...

       -depth d
              visual depth in bits

       -private
              forces a private colormap.

       -shared
              forces a shared colormap.

       -stdcmap
              forces a standard colormap.

FEATURES

   Mounting/Unmounting of Disks:
       The program allows non-root users to securely mount/unmount disks.  Disks are mounted with
       the  nosuid  flag to increase security.  The type of disk should be detected automagically
       by reading its partition table.  Only the first disk partition encountered will be mounted
       by jaZip.

   Write Protection/De-Write Protection:
       The program allows non-root users to control the disk's software write protection feature.
       Password protection is not currently supported.

   Ejection of Media:
       Any questions?

   Disk Information:
       Keeps you informed about the current disk's protection and mount status.

   Other information:
       Once the program is running, see the  online  help  (under  the  help  menu)  for  further
       information and instructions.

USER ACCESS TO JAZIP

       On  Debian  systems, jazip is installed suid to root, and sgid to floppy.  Access to jazip
       is limited to users in the floppy group.  To add user  joe  to  group  floppy  ,  run  the
       following command as root

       # adduser joe floppy

   What about non-Debian systems?
       You may change permission and group ownership of the jazip executable like so:

       # chown root:floppy /usr/bin/jazip

       # chmod 4754 /usr/bin/jazip

       to yield

       # ls -l /usr/bin/jazip

       -rwsr-xr-- 1 root jazip 147340 May 18 15:04 /usr/bin/jazip

OWNERSHIP AND PERMISSIONS OF MOUNT POINTS

       This is what is suggested

       # chmod 1771 /zip

       to yield

       drwxrwx--t 3 root floppy 1024 May 21 10:58 /zip

       Only  members of the floppy group can read it, all floppy group members can write to it at
       any time, but can't overwrite other user's files.  This only matters  for  ext2  formatted
       disks  because  jazip's  mount  changes  ownwership of the mount for vfat formatted disks:
       whoever uses jazip to mount the disk owns the files.  No other user can write to the disk.

KNOWN LIMITATIONS

   Starting the program:
       There needs to be a disk in the drive in order to start the program.  If you  start  jazip
       from  a window manager menu without a disk in the drive, it will fail silently because you
       will never see the text error message.

   Partitioning your disks:
       Since Zip and Jaz are removable media technologies, it is  assumed  that  each  disk  will
       contain  just  one  partition.  This is less likely to be desireable if you are a Jaz user
       with 1G or 2G disks.  In order to easily support autodetection of disk types, I don't  see
       a way around this restriction.

   Unmounting disks to access some features:
       Currently, to use the lock and unlock features, the disk must be unmounted.

CONFIGURATION FILE

       jazip  uses the file /etc/jazip.conf to map the raw SCSI device name of the drive you wish
       to use onto its mount point.  If you have more than one drive  on  your  system,  you  can
       create  a  separate entry in the configuration file for each one, and then specify the raw
       device name of the drive you want to use on the command line when you invoke jazip.  If no
       device  name  is given on the command line, jazip will use the settings in the first entry
       of /etc/jazip.conf by default.

       The format of the jazip.conf file should be mostly self-explanatory.  The first  entry  of
       the  configuration  file  is  the raw SCSI device name of your drive (e.g. /dev/sda).  The
       second entry is the mount point you wish to use (e.g. /zip).  The additional  entries  are
       required,  but  are  not  user-changeable.  See the jazipconfig(8) man page for specifics.
       See the jazipconfig command to create the /etc/jazip.conf configuration file.
