Raspberry Pi 3, fax


sudo apt-get update
sudo apt-get upgrade -y
sudo rpi-update
sudo reboot

sudo apt-get install hylafax-server sendmail -y --force-yes
find /sys/bus/usb/devices/usb*/ -name dev

tty/ttyACM0/dev is my USB fax modem found


special note, install sendmail, did not workout

uses ssmtp and gmail, works for single fax to email address, do not know why

Normal fax line, testing is expensive and wasting money, try local loop fax line, uses +12V battery and two 1K resistors to pull up the fax line, it is used to simulates phone line power of telephone company, no dial tone, and manually answering fax machine for testing, or abort (not working on Pi 3), on Pi 3 terminal

sudo faxanswer -h fax ttyACM0

sudo faxabort ttyACM0


restart hylafax

sudo /etc/init.d/hylafax restart

sudo faxsetup



Uses Gmail account and Pi 3 to send email to yourself for testing

Google account setting
# Login to your gmail account
# Go to: Settings -> Accounts and Import -> Other Google Account settings
# Go to: Personal info & privacy -> Account overview
# Go to: Sign-in & security -> Connect apps & sites
# Set option Allow less secure apps to ON


Now, on Pi 3, this is complete and tested command line script
copy and paste to Pi terminal, will run.
on Raspberry Pi 3, terminal,

## Install SSMTP & GEDIT, for send email, Gedit for GUI text editor, easy than uses vi
sudo apt-get install ssmtp gedit

## Save & copy original conf file to be .bak
sudo cp /etc/ssmtp/ssmtp.conf /etc/ssmtp/ssmtp.conf.bak

## Create new conf file (with vi, or some other text editor)
## sudo vi /etc/ssmtp/ssmtp.conf

## open GUI editor as root previlage, edit /etc/ssmtp/ssmtp.conf
gksudo gedit /etc/ssmtp/ssmtp.conf



————- ssmtp.conf, file content is following————

# Debug=Yes

————- ssmtp.conf, file content is end————



on Raspberry Pi 3, terminal again,

## Secure conf file
sudo groupadd ssmtp
sudo chown :ssmtp /etc/ssmtp/ssmtp.conf

## If you have error on this step like ''cannot access'' ...
## you must find ssmtp file and use that path: sudo find / -name "ssmtp"

sudo chown :ssmtp /usr/sbin/ssmtp
sudo chmod 640 /etc/ssmtp/ssmtp.conf
sudo chmod g+s /usr/sbin/ssmtp

## Sending mail to yourself, from (only one) command line 
echo "This is a test echo by command line" | ssmtp your_account@gmail.com

## or
printf "To: your_account@gmail.com\nFrom: RaspberryPi3\nSubject: printf Testing send mail from Raspberry\n\nThis is test. \nBest Regards\n" | ssmtp -t



build test.txt as email template for testing,

gksudo gedit test.txt



——————– content of test.txt———————
To: your_account@gmail.com
From: your_account@gmail.com
Subject: Testing send mail from Raspberry, by send test.txt file

This is test mail (body)

Best Regards!
