Raspberry Pi 1e installation
|
|
|
|
--------
|
|
Before 1e boot:
|
|
|
|
Add "ssh" file In The Boot Partition
|
|
|
|
"ssh" is empty
|
|
|
|
--------
|
|
|
|
Find ip-adres in router and log in via ssh (user: pi, password: raspberry)
|
|
|
|
Add user and make sure it has the same UID as your other machines (for convenience):
|
|
|
|
in "/etc/passwd" you cab find the UID of users
|
|
|
|
Add user:
|
|
adduser user_name
|
|
|
|
Change UID with command:
|
|
usermod -u 1001 user_name
|
|
|
|
Add new user to all the groups 'pi' is also in:
|
|
|
|
File "/etc/group"
|
|
Change all entries. For example: adm:x:4:pi becomes adm_x:username,pi")
|
|
|
|
Add new user to sudo:
|
|
usermod -aG sudo user_name
|
|
|
|
REBOOT SYSTEEM!
|
|
|
|
Login as new user and test (don't forget to test sudo!
|
|
|
|
Remove pi-user:
|
|
sudo deluser -remove-home pi
|
|
sudo rm -vf /etc/sudoers.d/010_pi-nopasswd
|

|
SSH loggin without password:
|
|
On local-machine (if not already done, check with "ls ~/.ssh/id_*"):
|
|
ssh-keygen -t rsa -b 4096
|
|
|
|
Copy the keu:
|
|
ssh-copy-id remote_username@server_ip_address
|
|
|
|
Log in on remote, now without passworrd
|
|
|
|
Disable login with password on remote: (optional; don't loose the key!)
|
|
open file "/etc/ssh/sshd_config"
|
|
|
|
Change:
|
|
PasswordAuthentication no
|
|
ChallengeResponseAuthentication no
|
|
UsePAM no
|
|
|

|
|
Change login schreen by editing the text file "/etc/motd".
|
|
|
|
Change the "sshd_config" to (if you now get two motd's, change it back to no)
|

sudo nano /etc/hostname
|
|
sudo nano /etc/hosts

|
|
LOCALE settings
|
|
|
|
sudo raspi-config
|
|
Than Localisation options / change locale (en_US.UTF-8 UTF-8)
|

Apache webserver and php
|
|
|
|
sudo apt-get install apache2 php
|
|
sudo chown www-data:www-data /var/www/html/
|
|
sudo usermod -aG www-data marcel
|
|
sudo chmod g+w /var/www/html/
|

Add firewall:
|
|
|
|
sudo apt install ufw
|
|
sudo ufw allow ssh
|
|
sudo ufw allow http
|
|
sudo ufw allow https

Enable I2C RTC
|
|
|
|
sudo rapi-config
|
|
enable i2c
|
|
sudo reboot
|
|
|
|
sudo apt-get install i2c-tools
|
|
|
|
sudo i2cdetect -y 1
|
|
#68 is RTC
|
|
|
|
sudo nano /boot/config.txt
|
|
dtoverlay=i2c-rtc,ds1307
|
|
|
|
sudo reboot
|
|
sudo i2cdetect -y 1
|
|
You should see a wall of text appear, if UU appears instead of 68 then we have successfully loaded in the Kernel driver for our RTC circuit.
|
|
|
|
Disable fake hardware clock:
|
|
sudo apt-get -y remove fake-hwclock
|
|
sudo update-rc.d -f fake-hwclock remove
|
|
sudo systemctl disable fake-hwclock
|
|
|
|
|
|
sudo nano /lib/udev/hwclock-set
|
|
Find
|
|
|
|
if [ -e /run/systemd/system ] ; then
|
|
exit 0
|
|
fi
|
|
|
|
Replace With
|
|
|
|
#if [ -e /run/systemd/system ] ; then
|
|
# exit 0
|
|
#fi
|
|
|
|
|
|
Also comment out the two lines
|
|
/sbin/hwclock --rtc=$dev --systz --badyear
|
|
and
|
|
/sbin/hwclock --rtc=$dev --systz
|
|
|
|
Read RTC:
|
|
sudo hwclock -r
|
|
|
|
Set RTC from system time:
|
|
sudo hwclock -w

kissattach and kissutil can only be executed as root. But we don't want to enter a password when starting the pe1rxf-scripts as the aprs-server has to work autonomous. We also don't want to run all the scripts as root, because that's a safety risk. The solution is to add the following lines to the sudoers-file:
|
|
|
|
sudo visudo
|
|
marcel ALL = (root) NOPASSWD: /usr/sbin/kissattach
|
|
marcel ALL = (root) NOPASSWD: /usr/sbin/kissparms
|
|
marcel ALL = (root) NOPASSWD: /usr/bin/socat

Install software from PE1RXF (meezenest.nl/mees):
|
|
|
|
Start ax.25 interfaces (direwolf and kiss) in crontab of user marcel.
|
|
Delay of 60 sec, otherwise direwolf will not start. Probably no sound card module loaded at time crontab is executed:
|
|
|
|
crontab -l
|
|
|
|
Add:
|
|
# Start APRS server at boot time
|
|
@reboot sleep 60 && /home/marcel/ham/start_aprs_server.sh
|
|
|
|
A default crontab is included in the ham/aprs_utils directory. Two more processes are in there for the custom telemetry.
|
|
|
|
The web-interface uses php to do some tasks. Make sure that at least the following files and directories can be accessed by user www-data:
|
|
ham/aprs_utils/aprs_files_to_transmit/ (rwx)
|
|
ham/aprs_utils/aprs_log/ (rwx)
|
|
ham/aprs_utils/send_message.sh (rx)
|
|
|
|
Make a symbolic link from ham/web-interface/ to /var/log/www/html/ and place all web-files in this folder.
|
|
|
|
MAKE IMAGE OF SD_KAART!
|
|
Use the script 'pishrink.sh' to compress the image.
|
|
At 1st boot, the image is automatically expanded (or not if you have choosen to to it manually. Than do that with sudo raspi-config.
