Setting Up a Raspberry Pi for Dev Side-projects
The Raspberry Pi is a great device for dev side-projects, such as a home media station, an IoT device, or a local server. Here are some of my go-to configurations when setting one up.
Booting with Connectivity
- Create a
wpa_supplicant.conf
in theboot
directory for wireless connections- More info here
- Create a
ssh
file in theboot
directory to enable SSH
OpenSSH
- OpenSSH options are set in
/etc/ssh/sshd_config
# disable root login
PermitRootLogin no
# allow only specific users
AllowUsers user1 user2
# allow only specific groups
AllowGroups groupA groupB
# change sshd port number
Port 123
# change login grace time
LoginGraceTime 1m
# restrict the interface to login
ListenAddress 192.168.1.123
ListenAddress 192.168.0.456
# disconnect ssh when no activity
ClientAliveInterval 300
ClientAliveCountMax 0
Security
Add User and Password
sudo /usr/sbin/useradd --groups sudo -m user123
sudo passwd user123
Reset Root Password
