<H2>DESCRIPTION</H2><PRE>
|
|
|
|
|
<B>saned</B> is the SANE (Scanner Access Now Easy) daemon that allows remote
|
|
|
|
|
clients to access image acquisition devices available on the local
|
|
|
|
|
host.

<H2>OPTIONS</H2><PRE>

2010-02-10 15:23:52 +00:00
|
|
|
The <B>-a</B> flag requests that <B>saned</B> run in standalone daemon mode. In this
|
|
|
|
|
mode, <B>saned</B> will detach from the console and run in the background,
|
|
|
|
|
listening for incoming client connections; <B>inetd</B> is not required for
|
|
|
|
|
<B>saned</B> operations in this mode. If the optional <B>username</B> is given after
|
|
|
|
|
<B>-a</B> , <B>saned</B> will drop root privileges and run as this user (and group).
|
|
|
|
|
|
2008-02-14 01:57:19 +00:00
|
|
|
The <B>-d</B> and <B>-s</B> flags request that <B>saned</B> run in debug mode (as opposed to
|
2010-02-10 15:23:52 +00:00
|
|
|
<B><A HREF="inetd.8.html">inetd(8)</A></B> mode). In this mode, <B>saned</B> explicitly waits for a connection
|
2008-02-14 01:57:19 +00:00
|
|
|
request. When compiled with debugging enabled, these flags may be fol-
|
2010-02-10 15:23:52 +00:00
|
|
|
lowed by a number to request debug info. The larger the number, the
|
|
|
|
|
more verbose the debug output. E.g., <B>-d128</B> will request printing of
|
2008-02-14 01:57:19 +00:00
|
|
|
all debug info. Debug level 0 means no debug output at all. The default
|
2010-02-10 15:23:52 +00:00
|
|
|
value is 2. If flag <B>-d</B> is used, the debug messages will be printed to
|
2008-02-14 01:57:19 +00:00
|
|
|
stderr while <B>-s</B> requests using syslog.
|
|
|
|
|
|
|
|
|
|
If <B>saned</B> is run from inetd or xinetd, no option can be given.

<H2>CONFIGURATION</H2><PRE>
|
|
|
|
|
First and foremost: <B>saned</B> is not intended to be exposed to the internet
|
|
|
|
|
or other non-trusted networks. Make sure that access is limited by tcp-
|
2010-02-10 15:23:52 +00:00
|
|
|
wrappers and/or a firewall setup. Don't depend only on <B>saned</B>'s own
|
|
|
|
|
authentication. Don't run <B>saned</B> as root if it's not necessary. And do
|
2008-02-14 01:57:19 +00:00
|
|
|
<B>not</B> install <B>saned</B> as setuid root.
|
|
|
|
|
|
2010-02-10 15:23:52 +00:00
|
|
|
The <I>saned.conf</I> configuration file contains both options for the daemon
|
|
|
|
|
and the access list.
|
|
|
|
|
|
|
|
|
|
<B>data_portrange</B> = <I>min</I><B>_</B><I>port</I> - <I>max</I><B>_</B><I>port</I>
|
|
|
|
|
Specify the port range to use for the data connection. Pick a
|
|
|
|
|
port range between 1024 and 65535; don't pick a too large port
|
|
|
|
|
range, as it may have performance issues. Use this option if
|
|
|
|
|
your <B>saned</B> server is sitting behind a firewall. If that firewall
|
|
|
|
|
is a Linux machine, we strongly recommend using the Netfilter
|
|
|
|
|
<I>nf</I><B>_</B><I>conntrack</I><B>_</B><I>sane</I> module instead.
|
|
|
|
|
|
|
|
|
|
The access list is a list of host names, IP addresses or IP subnets
|
|
|
|
|
(CIDR notation) that are permitted to use local SANE devices. IPv6
|
|
|
|
|
addresses must be enclosed in brackets, and should always be specified
|
|
|
|
|
in their compressed form. Connections from localhost are always permit-
|
|
|
|
|
ted. Empty lines and lines starting with a hash mark (#) are ignored. A
|
|
|
|
|
line containing the single character ''+'' is interpreted to match any
|
|
|
|
|
hostname. This allows any remote machine to use your scanner and may
|
|
|
|
|
present a security risk, so this shouldn't be used unless you know what
|
|
|
|
|
you're doing.
|
|
|
|
|
|
|
|
|
|
A sample configuration file is shown below:
|
|
|
|
|
|
|
|
|
|

The case of the host names does not matter, so AHost.COM is considered
|
|
|
|
|
identical to ahost.com.

<H2>INETD CONFIGURATION</H2><PRE>
|
|
|
|
|
For <B>saned</B> to work properly in its default mode of operation, it is also
|
|
|
|
|
necessary to add a configuration line to <I>/etc/inetd.conf</I>. Note that
|
|
|
|
|
your inetd must support IPv6 if you want to connect to saned over IPv6
|
|
|
|
|
; xinetd and openbsd-inetd are known to support IPv6, check the docu-
|
|
|
|
|
mentation for your inetd daemon.
|
2008-02-14 01:57:19 +00:00
|
|
|
|
|
|
|
|
The configuration line normally looks like this:
|
|
|
|
|
|
|
|
|
|
sane-port stream tcp nowait saned.saned /usr/sbin/saned saned
|
|
|
|
|
|
|
|
|
|
However, if your system uses <B><A HREF="tcpd.8.html">tcpd(8)</A></B> for additional security screening,
|
2010-02-10 15:23:52 +00:00
|
|
|
you may want to disable saned access control by putting ''+'' in
|
|
|
|
|
<I>saned.conf</I> and use a line of the following form in <I>/etc/inetd.conf</I>
|
2008-02-14 01:57:19 +00:00
|
|
|
instead:
|
|
|
|
|
|
|
|
|
|
sane-port stream tcp nowait saned.saned /usr/sbin/tcpd
|
|
|
|
|
/usr/sbin/saned
|
|
|
|
|
|
2010-02-10 15:23:52 +00:00
|
|
|
Note that both examples assume that there is a <B>saned</B> group and a <B>saned</B>
|
|
|
|
|
user. If you follow this example, please make sure that the access
|
|
|
|
|
permissions on the special device are set such that <B>saned</B> can access
|
2008-02-14 01:57:19 +00:00
|
|
|
the scanner (the program generally needs read and write access to scan-
|
|
|
|
|
ner devices).
|
|
|
|
|
|
2010-02-10 15:23:52 +00:00
|
|
|
If xinetd is installed on your system instead of inetd the following
|
2008-02-14 01:57:19 +00:00
|
|
|
example for xinetd.conf may be helpful:
|
|
|
|
|
|
|
|
|
|
# default: off
|
|
|
|
|
# description: The sane server accepts requests
|
|
|
|
|
# for network access to a local scanner via the
|
|
|
|
|
# network.
|
|
|
|
|
service sane-port
|
|
|
|
|
{
|
|
|
|
|
port = 6566
|
|
|
|
|
socket_type = stream
|
|
|
|
|
wait = no
|
|
|
|
|
user = saned
|
|
|
|
|
group = saned
|
|
|
|
|
server = /usr/sbin/saned
|
|
|
|
|
}
|
|
|
|
|
|
2010-02-10 15:23:52 +00:00
|
|
|
Finally, it is also necessary to add a line of the following form to
|
2008-02-14 01:57:19 +00:00
|
|
|
<I>/etc/services</I>:
|
|
|
|
|
|
|
|
|
|
sane-port 6566/tcp # SANE network scanner daemon
|
|
|
|
|
|
2010-02-10 15:23:52 +00:00
|
|
|
The official IANA short name for port 6566 is "sane-port". The older
|
2008-02-14 01:57:19 +00:00
|
|
|
name "sane" is now deprecated.

The hosts listed in this file are permitted to access all local
|

|
|
SANE devices. Caveat: this file imposes serious security risks
|
|
|
|
|
and its use is not recommended.

|
|

<I>/etc/sane.d/saned.users</I>

If this file contains lines of the form

|
|
|
user:password:backend
|
|
|
|
|
|
|

access to the listed backends is restricted. A backend may be

listed multiple times for different user/password combinations.

The server uses MD5 hashing if supported by the client.

|
<B>SANE_CONFIG_DIR</B>
|
|
|
|
|
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 /etc/sane.d. If the
|
|
|
|
|
value of the environment variable ends with the directory sepa-
|
|
|
|
|
rator character, then the default directories are searched after
|
|
|
|
|
the explicitly specified directories. For example, setting
|
|
|
|
|
<B>SANE_CONFIG_DIR</B> to "/tmp/config:" would result in directories
|
|
|
|
|
"tmp/config", ".", and "/etc/sane.d" being searched (in this
|
|
|
|
|
order).
