Setup

``` bash caption="/etc/network/interfaces" linenums="1" auto lo

iface lo inet loopback iface eth0 inet dhcp

allow-hotplug wlan0 auto wlan0

iface wlan0 inet dhcp wpa-ssid "ssid" wpa-psk "password" 

## For static IP address

``` bash title="/etc/network/interfaces" linenums="1"
iface eth0 inet static
address <static-ip>
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1

Disable Power saving mode

Set up Hostname

Setting up your Raspberry with a hostname can be very useful if it is connected to a network with DHCP Server. Instead of searching for the IP of the RPi you can find it by it's hostname.

  • install samba and the samba tools 
    sudo apt-get install samba samba-common-bin
sudo apt-get install netatalk # for avahi setup for mac
  • change the hostname in the following files 
    sudo vim /etc/hostname
sudo vim /etc/hosts
# or
sudo hostname <new_host_name>
  • restart hostname service 
    sudo service hostname.sh start

Now you can connect to your RPi with your hostname

SSH Connect

Regenerate ssh keys to be safe

rm /etc/ssh/ssh_host_* && dpkg-reconfigure openssh-server

Connect via remote PC

ssh pi@<hostname>
# or for mac
ssh <hostname>.local -l <username>

Resolve ssh lang issue

/etc/ssh/ssh_config
# Comment the following line
# SendEnv LANG LC...

Add the following environment variables into your ~/.bash_profile
