LuckFox-Pico-Mini-B SSH login

2024-05-03 22:27

I downloaded and flashed the firmware\buildroot\Luckfox_Pico_Mini_B_Image from the Google disk under Windows using Soc Toolkit.
I assigned the 172.32.0.93 address to connection.

Code: Select all

usb0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.32.0.93  netmask 255.255.0.0  broadcast 172.32.255.255

        TX packets 25  bytes 4922 (4.9 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

And now I can't connect via ssh.

Code: Select all

~$ ssh root@172.32.0.93
root@172.32.0.93's password:
Permission denied, please try again.

1. Make sure the password you entered is completely correct. Passwords are case-sensitive, so check if Caps Lock was accidentally activated. If possible, try entering the password in another terminal or application to verify its correctness before attempting to log in via SSH.
2. Ensure that your Windows computer and the development board are on the same local network. This means setting up a USB virtual network port.

Password correct. I can enter through adb and login ssh both local and outer addresses:

Code: Select all

adb.exe shell                                                                                                                                  
* daemon not running; starting now at tcp:5037
* daemon started successfully
# ssh root@localhost
root@localhost's password:
# pwd
/root
# exit
Connection to localhost closed.
# ssh root@172.32.0.93
root@172.32.0.93's password:
# pwd
/root
# exit
Connection to 172.32.0.93 closed.
#

But if I try to ssh from host computer, I get an error. I think the issue is that some setting in /etc/ssh/sshd_config is incorrect.
Example connect from linux host at Verbose mode:

Code: Select all

When the development board is connected to a virtual machine or an Ubuntu host, it registers as a virtual network interface. We need to ensure that this virtual network interface and the development board are in the same LAN. As mentioned earlier, being in the same LAN is crucial for successful SSH connection. The current testing is based on Ubuntu 22.04.

Code: Select all

sudo ip addr add 172.32.0.100/24 dev enx12f2609218cf
sudo ip link set enx12f2609218cf up

Thank you very much. This is my first time working with virtual adapters and I confused myself with the addresses.
By the way, in Ubuntu, rtsp does not work in vlc, so I had to install the Flatpack version.
Now everything works.

In the Ubuntu environment, you can use the ffplay command for streaming, and the camera's image delay is much smaller than VLC in the Windows environment. Overall, thank you for your active feedback.
