Versions of HP-UX
Lo guys, I've just started a new department in work and I'm going to be using HP-UX with Vi. The problem is I'm completely new to UNIX, I'm currently learning at work but I only have limited amounts of time on our dev systems. Is it possible to get a free/educational version any where? I don't mind if it's a restricted version as I won't be loading any systems onto it, I essentially need it just for 1-2 months to practice my commands and getting my head around the file structure and processes it uses.
Cheers
John

sane-qcam
sane-qcam(5) SANE Scanner Access Now Easy sane-qcam(5)
NAME
sane-qcam - SANE backend for Connectix QuickCam cameras
DESCRIPTION
The sane-qcam library implements a SANE (Scanner Access Now Easy) backend that provides access Connectix QuickCam cameras.
DEVICE NAMES
This backend expects device names of the form:
port
Where port is the I/O port address at which the device resides. This address is normally specified in hexadecimal using C syntax (e.g.,
0x37b) and may be prefixed with the letter "u" (e.g., u0x37b) to force the backend to access the camera in uni-directional mode.
CONFIGURATION
The contents of the qcam.conf file is a list port addresses that may be connected to a Connectix QuickCam. Empty lines and everything
starting from a hash mark (#) up to the end of a line are ignored. A sample configuration file is shown below:
0x37b # /dev/lp0
0x378 # /dev/lp1
u0x278 # /dev/lp2 forced in uni-directional mode
0x3bc # /dev/lp0 (alternate address)
In general, it is safest to list only the port addresses that really correspond to a QuickCam. For example, if one of the listed addresses
actually connect to a printer, then starting up this backend will cause the printer to perform a device reset (which is generally undesir-
able).
FILES
/etc/sane.d/qcam.conf
The backend configuration file (see also description of SANE_CONFIG_DIR below).
/usr/lib64/sane/libsane-qcam.a
The static library implementing this backend.
/usr/lib64/sane/libsane-qcam.so
The shared library implementing this backend (present on systems that support dynamic loading).
ENVIRONMENT
SANE_CONFIG_DIR
This environment variable specifies the list of directories that may contain the configuration file. Under UNIX, the directories
are separated by a colon (`:'), under OS/2, they are separated by a semi-colon (`;'). If this variable is not set, the configura-
tion file is searched in two default directories: first, the current working directory (".") and then in /etc/sane.d. If the value
of the environment variable ends with the directory separator character, then the default directories are searched after the explic-
itly specified directories. For example, setting SANE_CONFIG_DIR to "/tmp/config:" would result in directories "tmp/config", ".",
and "/etc/sane.d" being searched (in this order).
SANE_DEBUG_QCAM
If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. E.g.,
a value of 128 requests all debug output to be printed. Smaller levels reduce verbosity.

BUGS
Support is currently limited to the color version of the QuickCam. The black-and-white camera is starting to work too, but I don't believe
it works in all cases yet. Reportedly, acquiring images of certain sizes work fine, but others result in shifted images (sounds like a
problem due to byte-padding).
The program needs root-privileges since it needs to be able to access the camera's I/O ports.
