- I have a working USB scanner on this computer.
- I need saned to be working [Not bad or hidden] so I can access it from another Ubuntu 18.04.1 computer.
- Ubuntu 18.04.1 Exclusively on Both computers and updated within the last 24 hours
- Both are HP:
- This one an HP 110-220z with an attached HP Office Jet Pro 6830 all-in-one Scanner printer.
- The one I want to access the Scanner from is a HP Envyt 1200
- XSane produces scanned images from the scanner.
I have followed all the steps in
https://help.ubuntu.com/community/SaneDaemonTutorial
and
Failed to start saned.service: Unit saned.service is masked
including adding
## Access list

to
/etc/sane.d/saned.conf:
up to the point where I get
● saned.service
Loaded: masked (/dev/null; bad)

After doing the following I Rebooted
and got the same as above.
Where and What next?

Tried reading
but only found a confusing array of what I could do.
Not what I should do to inetd.conf (or /etc/xinetd.conf) and services! to properly configure them for "saned.service" to work_
/etc/services does contain:##
sane-port 6566/tcp # SANE network scanner daemon
/etc/inetd.conf does not exist, should it?##
It is not offered in Ubuntu software.##
What is used instead for this entry in inetd.conf?
sane-port stream tcp nowait saned.saned /usr/local/sbin/saned saned
or, if your system is using tcpd, a line like this:
sane-port stream tcp nowait saned.saned /usr/local/sbin/tcpd saned
If it is needed How do I find out which of these my system is using
/etc/xinetd does not exist. Should it?##
It is not offered in Ubuntu software.
What is used instead for this entry in xinetd?
Your /etc/xinetd.conf should contain a block like this:
service sane-port
{
socket_type = stream
server = /usr/local/sbin/saned
protocol = tcp
user = saned
group = saned
wait = no
disable = no
}
None of the suggested questions below on this page seem relevant.
