Configuring `saned` as a service
|
|
================================
|
|
|
|
To launch `saned` automatically in response to an incoming connection,
|
|
configure it as a service managed by `inetd`, `xinetd`, or `systemd`.
|
|
|
|
First verify that /etc/services contains a line of the following form:
|
|
|
|
sane-port 6566/tcp # SANE network scanner daemon
|
|
|
|
If not, then add it. (The name "sane-port" has been assigned by IANA.)
|
|
|
|
|
|
The examples below assume there is a "saned" group and a "saned" user.
|
|
Make sure that the ACLs on the scanner device files are set such that
|
|
`saned` can access them for reading and writing.
|
|
|
|
|
|
`inetd` Configuration
|
|
---------------------
|
|
|
|
Configure `inetd` if your platform does not use `systemd` or `xinetd`.
|
|
Not all `inetd` implementations support IPv6; check its documentation.
|
|
|
|
Add a line in /etc/inetd.conf like the following:
|
|
|
|
sane-port stream tcp nowait saned.saned /usr/local/sbin/saned saned
|
|
|
|
|
|
`xinetd` Configuration
|
|
----------------------
|
|
|
|
Copy frontend/saned.xinetd.conf into the `xinetd` configuration files
|
|
directory (as /etc/xinetd.d/saned.conf).
|
|
|
|
|
|
`systemd` Configuration
|
|
-----------------------
|
|
|
|
Copy frontend/saned.socket and frontend/saned@.service into one of the
|
|
system-wide directories for unit files (/etc/systemd/system/).
|
|
|
|
The recommended way to adjust the service settings is with the command
|
|
`systemctl edit saned@`. This opens a file inside a text editor where
|
|
overrides may be entered. As an example, environment variables can be
|
|
set which are used to control debug logging in individual backends:
|
|
|
|
[Service]
|
|
Environment=SANE_DEBUG_DLL=255
|
|
Environment=SANE_DEBUG_BJNP=5
|
|
|
|
(Refer to the man pages of the appropriate backends for more details.)
|
|
|
|
It is recommended to build SANE with explicit `systemd` support, which
|
|
allows log messages from `saned` to be written to the journal. If SANE
|
|
is built without this support, the following override must be used:
|
|
|
|
[Service]
|
|
StandardInput=socket
