  Brother HL3170CDW
search "linux brother HL3170CDW" did give this web site
http://support.brother.com/g/b/downloadtop.aspx?c=us&lang=en&prod=hl3170cdw_all.
select linux and deb; I did not find how to continue ==> information
printer(cups) =>
sudo dpkg -i hl3170cdwcupswrapperdriver.....

browse to http://localhost:631/printers
HL3170CDW is available
Pint testpage works
changes default options
  media size A4
  two sided long edge binding
  toner save mode ON
PPD file is in /etc/cups/ppd/HL3170CDW.ppd

PROBLEM: not succeeded on ingrid ??? and tyo ???
       suggestions in
       https://wiki.ubuntu.com/DebuggingPrintingProblems#Network_printer
       did not help
But the printer can be reached at
       http://192.168.13.99:631/
       and can be configured ?
Problem is caused by the fact that the brother packages contain binary execautables for i386. These executables need some /lib32/... libraries.
WORKAROUND    apt install lib32gcc1

Epson Ecotank ET-2650 Printer

The printer driver package for the ET-2650 can be found on the epson website
https://epson.com/Support/Printers/All-In-Ones/ET-Series/Epson-ET-2650/s/SPT_C11CF47201
It is important to start on the epson.com website. Epson.be does not the linux OS.....
After selecting linux id did find

Epson ET-2650 Scanner

  1. Installation. ET-2650 is supported fom version 77 on:
    The newest version can be downloaded from hamrick.com. Note that the file seems always to be vuex6495.tgz, but its contents are updated/changed.

Where is emilia-2 ?

        # service avahi-daemon start

      

      
No process changes but emilia.local is remotely usable.

        Observation:

        There is a /etc/init/avahi-daemon..  AND
        /etc/init.d/avahi-daemon ??

        Next problem site try:

        sudo kill --USR1 process_id_of_avahi-daemon

        (this dumps information in /var/log/syslog)

        After simulatneous restart of emilia, ingrid and tyo (in that
        order), tyo.local is not available.

        On tyo there is a 

        avahi-daemon: running [tyo-2.local]

This seems to cause registering off tyo-2.local ?

      Avahi-daemon creates new hostname-2.local
        when global dynamic ipv6 is created (timing problem ?)

        

        Workaround:

      if e.g. tyo.local does not work, try tyo-2.local

      then on tyo

      service avahi-daemon restart

      after:

      Nas will be mounted on:

      

        
sudo mkdir /Shared /Backup /Public /Multimedia

      

      And some entries in /et/fstab are needed:

      

        
# NAS over nfs
nas.local:/Public	/Public	nfs	noauto,user,soft,port=2049,proto=tcp,rw	0	0
nas.local:/Shared	/Shared	nfs	noauto,user,soft,port=2049,proto=tcp,rw	0	0

      sudo apt update

      Problem: skype works, but login in with the same account only
      works after a reboot ?

      
Vuescan

      
download from www.hamrick.com.

      

      
wget -c www.hamrick.com/files/vuex6495.tgz

        tar -xzvf vuex6495.tgz

      

      
To make vuescan uasbale for any user:

      

      

        
root@emilia:~/vuescan# cat Install.sh
#! /bin/bash
# install vuescan from www.hamrick.com

# do not know what these are used for
cp ${DOWNLOADDIR}/vuescan.8ba ${INSTALLDIR}/vuescan.8ba

cp VueScan48x48.png /usr/share/icons/hicolor/48x48/apps/vuescan.png

      

      Now vuescan works for root user, but other users may not see the usb
      scanner

This was done for Canon Lide 30, when a Epson ET-2650 was added nothing more was done

      
    
        
  1. # lsusb
    
          Bus 002 Device 009: ID 04a9:220e Canon, Inc. CanoScan
          N1240U/LiDE 30
    
          this is the usb device.
    2. 
        
  2. # lsusb -v -d 04a9:220e
    
          gives more information of the device
    3. 
        
  3. Bus and device from 1) are used to make device accessible
          under /dev/
    
          # ls -l /dev/bus/usb/002/009

          /dev/bus/usb/002/009
    
          This is the problem since only the root user can access this
          device.
    4. 
        
  4. The default ubuntu rules (/lib/udev/rules.d) asume scanner
          devices are accessed by apps running as user/group scanner.
    
          Vuescan does run with normal user/group and can nnot access
          the /dev/usb/bus/device files.
    
          We install add_user_libsane.rules in /etc/udev/rules.d to
          create aan extended access list with our users.

Usenet access
To access usenet e.g. for ebook strips (https://www.eboek.info/downloaden-met-sabnzbd/)
    1. Install sabnnzbdplus
      sudo apt install sabnzbdplus
    2. edit /etc/default/sabnzbdplus
      # [required] user or uid of account to run the program as:
      #USER=
      USER=jean
      ...
      # [optional] hostname/ip and port number to listen on:
      #HOST=
      #PORT=
      HOST=localhost
      PORT=8080

    3. restart sabnzbdplus.
      The config can be done by connectiong to http://localhost:8080/

    4. Your usenet account (I use a usenet.farm block account)  should contain the config information
    5. One can reach sabnzbd as
      https://127.0.0.1:9090/sabnzbd/
      https://localhost:9090/sabnzbd/
      https://emilia:9090/sabnzbd/
      Note: firefox/mozilla needs a security exception for https to work...
    6. I store my nzb files under Downloads/www.ebooks.info and the complete files under Downloads/complete

ssh keys

      

      
rsa keys donot work with ssh on 16.04. you need a dsa key

        ssh-keygen -t dsa

        generates a id_dsa 2048 bit in ~/.ssh/id_dsa and
        ~.ssh/id_dsa.pub

      

      
if needed the id_dsa.pub must be added to
