Raspberry PI, Bonjour service, SSH and AFP

Raspbian Stretch Lite (without desktop)

  1. Download Raspbian Stretch Lite
  2. Install Raspbian with etcher to SD card
  3. Boot from SD card...

Basic configuration and Wifi connection

sudo raspi-config
  1. Change User Password :-) (default user pi with password raspberry)
  2. Change Localisation Options
  3. Enable SSH in Interfacing Options
  4. Configure WiFi in Network Options and change Hostname (in my case to pi)

If you have Wifi with hidden SSID, you will need change /etc/wpa_supplicant/wpa_supplicant.conf file and add scan_ssid=1:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

    psk="and password :)"

Reboot (sudo reboot) and then check with iwgetid if you are connected to your Wifi!

Install AFP and Bonjour service

Install netatalk thats provide AppleTalk Filing Protocol (AFP) interface.

sudo apt install netatalk

Install avahi

sudo apt install avahi-daemon
sudo apt install avahi-utils
sudo update-rc.d avahi-daemon defaults

Config AFPD with /etc/avahi/services/afpd.service

<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
   <name replace-wildcards="yes">%h</name>

PS: RackMac is define icon that will be shown in Finder (there is plenty other options e.g. Windows, Macintosh, TimeCapsule and so on)

Config SSH with /etc/avahi/services/ssh.service

<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
     <name replace-wildcards="yes">%h SSH</name>

Configure avahi daemon

Then in /etc/avahi/avahi-daemon.conf change two parametters host-name and publish-workstation:

host-name=pi # this row
# ...

publish-workstation=yes # this row

# ...

Now Awvvaaaahhhhiii

Enable afp and avahi

sudo systemctl enable netatalk
sudo systemctl enable avahi-daemon

and start them

sudo service avahi-daemon start
sudo service netatalk start

now check if everything works well with

avahi-browse -a | grep $(hostname)

wget -qO- | tar xvz -C ./nodejs
cd nodejs
sudo cp -R bin/* /usr/bin/
