       sane-net - SANE network backend

       The  sane-net library implements a SANE (Scanner Access Now Easy) back‐
       end that provides access to image acquisition devices through a network
       connection.   This  makes  it possible to control devices attached to a
       remote host and also provides a means to grant  users  access  to  pro‐
       tected resources.

       This backend expects device names of the form:


       Where host is the name (or IP address) of the (remote-) host and device
       is the name of the device on this host that should  be  addressed.   If
       the device name does not contain a colon (:), then the entire string is
       treated as the device string for the default host.  The default host is
       the host listed last in the configuration file (see below).

       An IPv6 address can be specified enclosed in square brackets:


       The  contents  of  the  net.conf	 file  is  a list of host names (or IP
       addresses) that should be contacted for scan requests.  Empty lines and
       lines  starting	with  a	 hash  mark  (#)  are ignored.	Note that IPv6
       addresses in this file do not need to be enclosed in  square  brackets.
       A sample configuration file is shown below:

	      # this is a comment

       The  above  list of hosts can be extended at run-time using environment
       variable SANE_NET_HOSTS.	 This environment variable  is	a  colon-sepa‐
       rated  list  of	hostnames  or IP addresses that should be contacted in
       addition to the hosts mentioned in the configuration file.   For	 exam‐
       ple, a user could set the environment variable to the string:[::1]

       To  request  that hosts , [::1] , and scan‐ are contacted in addition to the hosts listed above.

       For this backend to function properly, it is also necessary  to	define
       the  sane-port  service	in  /etc/services.  The sane service should be
       defined using a line of the following form:

	      sane-port 6566/tcp # SANE network scanner daemon

	      The  backend  configuration  file	 (see  also   description   of
	      SANE_CONFIG_DIR below).

	      The static library implementing this backend.

	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

	      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 config‐
	      uration file is searched in two default directories: first,  the
	      current	 working   directory   (".")   and   then   in	 /sys‐
	      tem/resources/sane-backends/1.0.18/etc/sane.d.  If the value  of
	      the environment variable ends with the directory separator char‐
	      acter, then the  default	directories  are  searched  after  the
	      explicitly   specified   directories.    For   example,  setting
	      SANE_CONFIG_DIR to "/tmp/config:" would  result  in  directories
	      "tmp/config",	".",	 and	 "/system/resources/sane-back‐
	      ends/1.0.18/etc/sane.d" being searched (in this order).

	      A colon-separated list of host names or IP addresses to be  con‐
	      tacted by this backend.

	      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.

       If saned has timed out, the net backend	may  loop  with	 authorization
