Debian is the default recommended image for the Raspberry Pi. If you’re using the Raspberry Pi as a server you’ll most likely want to be able to manage it remotely over the network using a local computer and SSH. However, by default SSH isn’t enabled on the Pi. We’ll walk through the basics of getting SSH enabled and logging into the Raspberry Pi over SSH.
The first thing we need to do is log into the Pi normally by plugging in a monitor and keyboard. It also makes sense to plug in the network cable at this point. Once the board boots you get the login screen where the default username is
pi and password
If you want to change this password you can just type:
Now we’re going to enable SSH at boot. Luckily there’s a script that enables SSH for us provided so we just need to use the following command to move it to the right location:
sudo mv /boot/boot_enable_ssh.rc /boot/boot.rc
Once we’ve done this rebooting the Raspberry Pi will show something like:
Starting OpenBSD Secure Shell server: sshd
You should now be able to log in via SSH and the same username and password. To find the ip address we need to type:
Here we want to look for the ip address on eth0 for example if the output is
1: lo: mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: eth0: mtu 1488 qdisc pfifo_fast state UP qlen 1000 link/ether b8:27:eb:49:32:63 brd ff:ff:ff:ff:ff:ff inet 192.168.1.190/24 brd 192.168.1.255 scope global eth0
then our ip address is listed after inet as
192.168.1.190. You could even use
ip addr | grep -e 'inet .* eth0' to find just this line.
With this ip address you can now log in using the following credentials:
host: 192.168.1.190 (or whatever your IP was) username: pi password: raspberry (or whatever you changed it to)
On a unix based system this will most probably be:
From here you can manage the Pi fully over SSH. It’s also possible to remove the password altogether and use a public/private keypair to log in. This is especially recommended if the Pi is going to be publicly available on the internet. In the next post we’ll cover removing the password and just using the keypair.
