• 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

192.168.0.0/24

to

/etc/sane.d/saned.conf:

up to the point where I get

● saned.service

   Loaded: masked (/dev/null; bad)

   Active: inactive (dead)

After doing the following I Rebooted

and got the same as above.

Where and What next?

This is what I have done

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.

What do I do now?
