GENERAL NOTE
============
Due to history and structure of this package, the server part of HylaFAX+ 
should only be installed in isolated environments for security reasons,
allowing direct access for admins only. [bsc#1173519]

Setup of hylafax+ on openSUSE
-----------------------------

After installation of hylafax you need to run

faxsetup

answer the questions and modify to your needs.

Run

faxaddmodem

for each attached modem. It asks you for the device, leave out the /dev prefix; 
only enter eg. modem, ttyS0 or similar device names. 
Answer the questions, important ones are related to ringtones, max pages, 
permissions on files or the name that should be shown on the tagline of send faxes.

Setting up hylafax for systemd
------------------------------

hylafax comes with a couple of systemd services. Two of them are needed to send
out faxes from your server:

hylafax-hfaxd.service - the hylafax server
hylafax-faxq.service - the fax scheduler

Enable these services with

systemctl enable hylafax-hfaxd.service
systemctl enable hylafax-faxq.service

They will be started at boot time.

systemd-timers
--------------

openSUSE has moved from cron to systemd-timers. By default we ship two timers, 
for cleaning the faxqueue and for usage statistics. You need to enable them in 
case you want to make use of these features:

systemctl enable hylafax-faxqclean.timer
systemctl enable hylafax-usage.timer

Receiving faxes
---------------

In order to receive faxes, you need to additinally run one faxgetty for each 
interface, e.g.:

systemctl start hylafax-faxgetty@ttyS0.service
systemctl start hylafax-faxgetty@ttyIAX0.service

Enable them at boot time with:

systemctl enable hylafax-faxgetty@ttyS0.service
systemctl enable hylafax-faxgetty@ttyIAX0.service

Setting up firewalld
--------------------
The server package installs a ready to use hylafax service and helper file.
For the simple case, you need to:

firewall-cmd --add-service hylafax

Please note, that the client tools faxstat and sendfax use a protocol similar
to FTP to transfer payload data. As long, as you don't mix hylafax with a ftp
server service, you're almost set at this point, and we would strongly advise
against such a setup! At least, it requires you to combine the ftp and hylafax
services and helpers into a single service and helper in /etc/firewalld, because
both use the same kernel helper module "nf_conntrack_ftp". Again, YMMV.

Additionally on the *clients*, you should switch the hylafax protocol to passive mode:

cat >> /etc/hylafax/hyla.conf << EOF
PassiveMode:    yes
EOF

After successfully checking the connection from the client with:

faxstat -hfaxserver -s

you can persist the firewalld settings with:

firewall-cmd --add-service hylafax --permanent

Send-only environment
---------------------

Many installations run hylafax just for sending faxes. To get this up and
running, the command

faxmodem

needs to run after hylafax is started.
For this we have created a separate service, hylafax-faxmodem@.service

You need to invoke this service with the interface, e.g.
systemctl enable hylafax-faxmodem@ttyS0.service

(Note: you may as well attach the faxmodem call to the faxq-service:
Create a directory
/etc/systemd/system/hylafax-faxq.service.d
and copy the file sendonly.conf into this directory.
Check that the mentioned port (ttyS0 - Parameter is the modem device) in this
file matches your configuration and restart the service.
Depending on how fast the FIFO comes up, you may see a restart of the service)
