I've been trying to establish ssh connection with my raspberry by adding config files (wpa_supplicant.conf, ssh) to boot section of sd card with raspberry OS. I've done everything right and usually after these steps I could easily connect to my raspberry.
But, now I can't do this.
Whenever I try to log into raspberry using 'pi' as login and 'raspberry' as password, it says that this is incorrect password. I tried reinstalling OS on sd card; however, it didn't help.
I don't have any other opportunities other than connecting to raspberry wirelessly.
I have Raspberry Pi 4B and Raspberry OS 64-bit
It seems that you are using the latest release of raspbian. Developers have made a huge step forward to the security and there is no more default user pi and password raspberry, no need of the wpa_supplicant.conf & ssh files (but they are still work).
For headless setup you can press settings button in the last version of Raspberry Pi Imager and configure User, Wi-Fi, SSH and so on.
Scroll down to the Headless setup chapter

I created a guide with images to do this here:
As per the official raspberry blog at https://www.raspberrypi.com/news/raspberry-pi-bullseye-update-april-2022 the default username password will no longer be allowed for headless login.
Basically there are two methods
Use the updated raspberry pi imager too from here
manually add userconf file in the boot directory with username:encrypted-password as a single line. to generate encrypted-password string use echo 'mypassword' | openssl passwd -6 -stdin tested on win 10

I am trying to log into my Raspberry Pi using PuTTY from Windows. However, whenever I try to log into my Raspberry Pi using the default username and password (pi* and raspberry) it says Access Denied.
I have the wpa_supplicant.conf file and ssh file created. This is its first bootup. I am using the latest version of the Raspbian Lite OS.
Recently, the default user setup of Raspbian was significantly changed, rendering most existing online tutorials invalid.
In essence, the default pi user no longer exists, so you have to create it and set its password using either the official Imager tool or by creating a userconf file in the boot partition of your microSD card, which should contain a single line of text: username:hashed-password, replacing username with the name of the user you want (e.g., pi) and hashed-password with the hash of the password you want.
According to the official guide, the easiest way to do this is by running the following in a terminal (Linux or macOS):
echo 'password' | openssl passwd -6 -stdin
Again, you should replace password with the password you want here.

The default username and password are no longer valid for Raspberry Pi.
If you are trying to log in headlessly (without a monitor and keyboard), you can do it from Raspberry Pi Imager itself.
On selecting the OS in Raspberry Pi Imager, you get an icon of settings in which you can
create a user
setup Wi-Fi
enable SSH
After configuring, you can continue flashing your memory card.
And on first boot you will be good to go.
I have solved this problem. You can easily input your username and password with Raspberry Pi Imager.
add the user you created when flashing the image to the ssh group.
usermod -a -G ssh YourPiUsername
I'm trying to boot into my Raspberry Pi 3b+ on my Turtlebot3 with the respective image (https://emanual.robotis.com/docs/en/platform/turtlebot3/sbc_setup/#sbc-setup).
I get to the point where I need to enter the login information, but ubuntu/ ubuntu doesn't work. I have also tried pi/ raspberry etc. but nothing is correct.
Am I missing something? Is the username and pw for this image different?
I just did a manual SBC setup, it took a while but worked out.
Update:
At least for the Melodic version
user = "ubuntu" and password = "turtlebot"
I have a raspberry pi but no external keyboard, mouse or ethernet cable to set it up - but I do have micro-sd card reader. Is there a way for me to just write my wireless internet config straight to the micro-sd card so the raspberry pi will be able to connect to the wifi, and then allow me to ssh in?
The micro-sd card already has Raspbian installed on it.
Sure.
Put the card in a drive and mount it.
Go to the partition called boot.
Create an empty file called ssh just using:
touch ssh # Works in Linux/macOS
type NUL >> ssh # Works in Windows
Create a file called wpa_supplicant.conf with your WiFi settings - be very sure that Windows hasn't added any .txt extension:
country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="NETWORK-NAME"
psk="NETWORK-PASSWORD"
}
Once it works, and you can ssh successfully into the Raspberry Pi, be sure to run:
sudo raspi-config
and permanently enable ssh for subsequent reboots.
I face a problem that I can ping to correct IP address, it have no loss. And also I use nmap ping the pi address, and I get it correctly. Then I using VNC viewer to try access to pi, but it always show up "The connection was refused by the host computer"
Did u all have any idea ?
Your problem indicates that your Raspberry Pi was reached by the connection attempt, but that no service was running on the relevant port and hence the connection was refused. I think, this is because the VNC service is not running on your Raspberry Pi.
Update 1
Raspbian now comes with the server by default thanks to a partnership with RealVNC, it just needs to be enabled.
Original
You must enable VNC Server on your Raspberry Pi using terminal
sudo apt-get update
sudo apt-get install realvnc-vnc-server
or you can also enable VNC Server on the command line using the sudo raspi-config command.
Advanced Options->VNC:Yes
Now you can connect to the VNC Server using a application such as VNC Viewer.
I have been having this issue with my Raspberry Pi Zero W even though it worked perfectly beforehand. This page https://www.realvnc.com/en/connect/docs/raspberry-pi.html should help.
I ran vncserver in a ssh window after verifying the interface settings in raspi-config.
It started the VNC Server and gave me the VNC Server catchphrase and the IP address with Port Number as shown in the photo linked below.
vncserver output
After running that command I was able to get the VNC Viewer on my windows machine to connect to the pi.
I then ran sudo systemctl enable vncserver-x11-serviced.service in the ssh window so that it would start automatically on subsequent reboots.
I've had this same problem but found a different reason. I found three ways to get around this error message.
Plug a mouse or keyboard into the Raspberry Pi zero, waking up the screen and the VNC connection.
Wait about 5 - 10 minutes which is the amount of time for the screen saver to kick in which seems to wake up VNC connection. but don't wait to long other wise run this command to get things going via ssh "systemctl start vncserver-x11-serviced.service".
I am hoping the new update they just published will fix this problem. I don't see this as much with the Raspi B3+ as with the Zero H.
The last was plug in both monitor and mouse and that for sure fixes the VNC issues but defeats the headless connection. It seems that running headless and the screen/saver are somehow related but just not smart enough to figure it out.
For people using newer version of Raspberry, VNC option is found under:
Config>Interface Options
pinging to any service will only tells us that whether the server is currently listening on that port or not. It will not tell you the possible result to connection request asked by client.
It seems that, you have installed VNC server but not started it properly. Use this command to start it...
# vncserver start
Also recheck the port number is correct or not.
With the Rasp Pi 4 - had connecting fail after rebooting both the server and client (both Rasp Pi 4s).
Took a while to realize that I have two clients: One named "VNC Client", the other "VNC Viewer for Google Chrome".
The former works, the latter doesn't.
There are Raspberry Pi 3 model B and MicroSD with NOOBS OS. Unfortunately I have not any display to get a direct access to NOOBS shell. So remote connection could be set via ssh. However my device does not have any IP-address. I read everywhere that the connection options must be set... via shell. But it's impossible for me!
How can I resolve this problem and get remote access to shell (or to desktop even)?
I ran into this a while ago, I started using PiBakery. It will write raspbian to the SD card and add a startup script to connect to the network and enable ssh. This way the first time you boot it up, its ready to go and you can connect via SSH.
When you set it up, it also allows you to set a static IP address so you know exactly where it is when it boots.
Enable SSH by placing a file named 'ssh', without any extension, onto the boot partition of the SD card.
Connect your device to your LAN using a wired connection.
From another computer on the network execute arp -a to view locally connected hosts and get your raspberry pi's IP address.
From there you should be able to SSH into your pi.
