I'm trying to SSH into my Pi from my laptop, but I type ssh pigio@192.168.178.79 into my laptop, I get an error Permission denied after entering the password.

  • I'm sure the IP address is correct, because I can PING the IP and get response
  • I'm quite sure that the password which I'm typing in is correct
  • I can SSH from the Pi to itself by typing ssh localhost and then entering the password
  • I added my WiFi network on the Pi by editing /etc/wpa_supplicant/wpa_supplicant.conf but it didn't connect to the Wifi, so I connected it to the Wifi from the settings. The configuration on the wpa_supplicant.conf file is still there, tho

I'm in wlan (yes, same network), the Pi is a Raspberry Pi 3, the laptop is a Mac running the latest OS version.

Is there anything else I can do to try to debug the problem and see why it isn't working?

UPDATE: Look like RSP has problems connecting automatically to a 5Ghz network. Can someone confirm this?

UPDATE 2 Ping result:

As it turned out you are facing two issues:

1) Connectivity

Your wifi uses the 5 GHz band but your Raspberry Pi 3 Model B can only connect to 2.4 GHz band wireless LAN (to be exact: "802.11n Wireless LAN", see Hardware Guide). As a result of the missing connectivity your RPi is not accessible from your Mac using SSH.

Suggested solution: connect your RPi using 2.4 GHz or use a Raspberry Pi 3 Model B+ (which supports dual-band wireless LAN) and connect it to 5 GHz.

2) User

Side note #1: "pigio" is (or: should be) the name of a user on this RPi and the hostname of this RPi.
Side note #2: /var/log/auth.log is located on the RPi.

You've successfull established a SSH connection from your laptop to your RPi by using the default user "pi", seeable in /var/log/auth.log:

Jun 13 19:43:51 pigio sshd[1019]: Accepted password for pi from 192.168.178.70 port 49273 ssh2
Jun 13 19:43:51 pigio sshd[1019]: pam_unix(sshd:session): session opened for user pi by (uid=0)

Conclusion: SSH is working (you've assumed it and now it's verified).

The SSH connection fails with the user "pigio" like documented in /var/log/auth.log:

Jun 10 21:34:13 pigio sshd[1086]: Invalid user pigio from 192.168.178.70 port 56997
Jun 10 21:34:13 pigio sshd[1086]: input_userauth_request: invalid user pigio [preauth]

Most probably the user "pigio" doesn't exist. To verify: please connect again to your RPi as the user "pi", run sudo grep -i pigio /etc/passwd. (Background information: This command will search case-insensitive for the username "pigio" in the user account information file of Raspbian and therefor it needs sudo power.)
If the result is empty (you see the cursor in a new blank line waiting for your next input) then the user does not exist (please see below for how to create a user).
If the result is something like pigio:x:1001:1001:,,,:/home/pigio:/bin/false then indeed the user does exist.

As it turned out the user "pigio" is nonexistent.

Suggested solution: create the user "pigio" and assign a password by:

sudo useradd --create-home --shell /bin/bash pigio
sudo passwd pigio

Another way to create a new user is adduser. For the differences please read the manpages: man useradd respective man adduser.

If you want to add the new user to sudoers and grant passwordless sudo access, then please read the official Raspberry Pi Documentation - User management in Raspbian.

To answer your comment "I will not have more then one user anyway": you can use the default user "pi" but it is not recommend for security reasons. I recommend to

But this is getting to be off-topic, so I'd suggest for details you please read Securing your Raspberry Pi - Raspberry Pi Documentation.

Make sure you activated ssh in the raspi-config!
-> sudo raspi-config -> Interfacing Options -> ssh -> enable

I had this issue and it turned out that the problem was that I was trying to change the password for the Raspberry PI by doing the following:

sudo passwd

and this was changing the password for the root user and not the pi user. I then set the password using this:

sudo passwd pi

and SSH connected correctly with the pi user. This may not be the exact issue experienced by OP, but mentioning it here in case other people encounter this issue due to their failure to set the password correctly for the pi user.

Try

ssh [custom-username]@[ip-address]

I was still using

ssh pi@[ip-address]
